final rationale
Mean of 4 draws (0.18, 0.16, 0.19, 0.19). (0) No source shows the condition met; the resolution-source fetch could not render the ISW map, and ISW-sourced reporting from Sept 21-22 says Russia is limited to small-group infiltration in the southwest, which the rules exclude. YES needs red shading at the likely-central intersection, persisting through a full ISW update cycle. (a) About 14 weeks remain, to Dec 31, 2026. (b) Status quo is NO: ISW reports 32 attacks a day with only insignificant results, Hannivka reportedly recaptured, and Operation Vivaldi disrupting the fortress-belt envelopment. (c) NO: the fall mechanized push stalls in mud season and under drone attrition, repeating the 2025 offensive that ended status quo ante; Azov's Prokopenko expects only one settlement to fall, and summer gains were about four times smaller than in 2025. (d) YES: concentrated Rubicon drone crews and a claimed 6:1 ratio, plus foot-only Ukrainian logistics, let Russian groups consolidate from the city's edges until ISW abruptly assesses control, as with Pokrovsk. The Sept 22 MoD encirclement claims are aggregator-only and contradicted by ISW, so I discount them. The 21.5% anchor is broadly consistent with the October market (5.5%) and comparable December markets; I shade slightly lower given no acceleration in the freshest ISW reporting.

Planner reasoning
Polymarket direct is the price anchor. The resolution source is the ISW map, with DeepStateMap as a fallback, and it will show how close the front line is to Dobropillia. Related Polymarket and Kalshi markets on nearby towns (Kramatorsk, Sloviansk, Kostiantynivka) give cross-market signals about how fast Russian forces are advancing, and Wikipedia gives background on the Dobropillia offensive.

Research loops, bottom lines
- current state: As of late September 2026, Dobropillia city itself (including the specified intersection) remains under Ukrainian control per all credible tracking (DeepState, ISW, Kyiv Independent-sourced reporting), with Russia conducting infiltration/assault operations and reportedly massing armor for a fall mechanized push, while a Ukrainian counteroffensive (Vivaldi) has set back Russia's broader encirclement plan; unverified pro-Russian claims of an "encirclement" on Sept 22, 2026 have not been corroborat
- base rate: The outside view strongly favors "No": Dobropillia has already survived one full Russian offensive cycle (Aug–Nov 2025) that failed outright, comparable nearby cities (Pokrovsk) took ~19 months of grinding attrition before an ambiguous "capture," and current prediction-market pricing for this specific capture question sits around 19% — well below even, and far below related "entry" markets that use a much lower bar for resolution.

- no case: All primary-source-adjacent reporting through Sept 22, 2026 (two days newer than colleagues' latest ISW citation) shows Russia still confined to unconsolidated infiltration in Dobropillia's southwest/north fringes — a status the market's own rules exclude from "capture" — while the city has already survived one complete Aug–Nov 2025 offensive cycle that fully reversed, and Russia's fall push (armor, Rubicon drones) is only beginning as the mud season approaches, arguing strongly for continued st

report: current state
- [2026-08-07] ISW assessed that Russia's operational plan to encircle Ukraine's Donetsk Oblast "fortress belt" (Kostiantynivka, Druzhkivka, Kramatorsk, Sloviansk) via Dobropillia and Pokrovsk, has an "extremely unrealistic" timeline. https://euromaidanpress.com/2026/09/15/huge-increase-in-russian-assault-groups-trying-to-break-through-to-dobropillia-but-they-are-using-familiar-tactics-staff-sergeant-says/
- [2026-09-14] DeepState's map showed Russian forces advancing toward Dobropillia but the city itself still marked as contested/approached rather than captured; a Ukrainian staff sergeant said
Ukrainian forces later reported that they had encircled and eliminated these troops
referring to earlier 2025 infiltrations, and described a fresh 2026 buildup. https://euromaidanpress.com/2026/09/15/huge-increase-in-russian-assault-groups-trying-to-break-through-to-dobropillia-but-they-are-using-familiar-tactics-staff-sergeant-says/
- [2026-09-14] A Svoboda Battalion staff sergeant said there had been a "huge increase" in Russian mobile assault groups pushing toward Dobropillia, but that
"To bring in an even larger number of fighters, I don't know how well they will manage that, because there is the factor of the physical ability to bring this number of people to the staging point and then lead this large number of people along the route,"
per Ukrainian analyst Davydenko, and that Ukraine had mined/blocked approach roads. https://euromaidanpress.com/2026/09/15/huge-increase-in-russian-assault-groups-trying-to-break-through-to-dobropillia-but-they-are-using-familiar-tactics-staff-sergeant-says/
- [2026-09-15] Third Army Corps commander Brig. Gen. Andriy Biletskyi confirmed a Ukrainian counteroffensive ("Operation Vivaldi") in northern Donetsk Oblast; Ukraine's Defense Forces had cleared 75 sq km and liberated 10 sq km, inflicting roughly 1,500 Russian casualties in that sector. https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-09-17/18] ISW reported Russia is moving armored vehicles into the Dobropillia sector and preparing mechanized attacks for fall 2026, with Azov Corps commander Prokopenko saying Russia's 51st, 41st and 8th Combined Arms Armies are preparing mechanized offensives, and that Russia would likely seek to capture "at least one settlement in the sector before the fall campaign ends." https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-09-17/18] ISW concluded Ukraine's Operation Vivaldi had disrupted Russia's attempt to encircle the fortress belt, and that Ukrainian advances north of Lyman made Russia's plan to envelop the fortress cities from north and south "already unrealistic." https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-09-14] A separate frontline tracker reported continued Russian assault attempts on the Dobropillia axis (26 recorded attacks on the wider Pokrovsk axis including Dobropillia) but concluded the evidence "does not establish a new major territorial capture inside the strict reporting window." https://nordexium.substack.com/p/ukraine-russia-14092026
- [2026-09-22] Non-primary "military summary" video channels reported a Russian Ministry of Defense claim that Dobropillia was "encircled," naming trapped Ukrainian units (4th & 15th Guard brigades, "Skala" regiment); these are unverified secondary/aggregator sources, not ISW, DeepState, or a mainstream outlet, and no independent confirmation of city capture was found. https://www.military-stuff.org/massive-strike-dobropillia-encircled-ms-2026-09-22/
- [2026-09-22] A second aggregator video framed the same Russian "encirclement" announcement as politically timed messaging ("timed for Trump") amid ongoing Trump-Zelensky diplomatic contacts, while noting a Ukrainian counterattack recaptured the village of Hannivka nearby — again unverified by primary sources. https://www.military-stuff.org/the-winter-deal-dobropillia-cauldron-no-winter-survival-total-loss-military-summary-2026-09-22/
- [2025-11-29] Background: the original 2025 "Dobropillia offensive" (Aug 11–Nov 29, 2025) ended in status quo ante bellum, with all Russian-held settlements in the pocket recaptured by Ukraine. https://en.wikipedia.org/wiki/Dobropillia_offensive
- [2026-07-26] Russia began a renewed push toward Dobropillia in summer 2026, reportedly using quad bikes and motorcycles in infiltration tactics similar to 2025, as flagged by Ukraine's National Guard. https://euromaidanpress.com/2026/09/15/huge-increase-in-russian-assault-groups-trying-to-break-through-to-dobropillia-but-they-are-using-familiar-tactics-staff-sergeant-says/
BOTTOM LINE: As of late September 2026, Dobropillia city itself (including the specified intersection) remains under Ukrainian control per all credible tracking (DeepState, ISW, Kyiv Independent-sourced reporting), with Russia conducting infiltration/assault operations and reportedly massing armor for a fall mechanized push, while a Ukrainian counteroffensive (Vivaldi) has set back Russia's broader encirclement plan; unverified pro-Russian claims of an "encirclement" on Sept 22, 2026 have not been corroborated by ISW or DeepState and should be treated as contested Russian information-operation claims rather than confirmed territorial change.
NOT FOUND: A direct, dated screenshot or textual description of the ISW interactive map's current color-coding at the exact coordinate (48.475882°N, 37.082566°E) as of September 2026; no ISW daily map update or DeepStateMap snapshot dated after September 18, 2026 could be retrieved to confirm whether any red shading has appeared at or near this specific intersection.
report: base rate
- [2025-08-11 to 2025-11-29] Russia's first major push toward Dobropillia (the "Dobropillia offensive") lasted over three months and ended in
status quo ante bellum, with initial Russian gains reversed and all involved settlements returning to Ukrainian control
, showing that rapid capture attempts against this target have historically failed. https://en.wikipedia.org/wiki/Dobropillia_offensive
- [2026-02-25] By comparison, the much larger and more strategically important city of Pokrovsk (Dobropillia's southern neighbor) took roughly 19 months of siege before ISW assessed
Russian forces have likely seized Pokrovsk in recent weeks — though the hollow victory has failed to yield the operational breakthrough the Kremlin desperately craved... based on the total lack of evidence of Ukrainian military activity within the city since late January 2026
, illustrating that "captures" in this sector are typically slow, attritional, and only confirmed well after the fact. https://english.nv.ua/russian-war/pokrovsk-falls-to-russia-but-kremlin-fails-to-exploit-its-capture-50587178.html
- [2026-09-21] The most recent ISW-sourced reporting shows Russia still has not entered Dobropillia proper:
Russia is carrying out an average of 32 attacks per day near Dobropillia but is not advancing... Russian forces are maintaining the highest tempo of offensive operations precisely in the Dobropillia direction, but have achieved only insignificant results there
. https://unn.ua/en/news/the-russian-army-failed-to-establish-a-foothold-near-dobropillia-despite-the-highest-rate-of-attacks-on-the-front-isw
- [2026-09-21] ISW further notes
Ukrainian forces also continue to hold positions in the Dobropillia direction in areas that Russian sources had previously claimed were captured by the Russian army
, indicating a pattern of Russian claims outrunning confirmed battlefield reality — a recurring feature of this reference class. https://unn.ua/en/news/the-russian-army-failed-to-establish-a-foothold-near-dobropillia-despite-the-highest-rate-of-attacks-on-the-front-isw
- [2026-09-19] ISW analysis (via secondary reporting) indicates Russia is regrouping for a renewed push, with
about 1,200 drone crews from Russia's elite Rubicon unit operating in the Dobropillia sector... Russian forces would likely begin reinforcing their existing assault units, numbering about 200 infantry troops, with mechanized columns of about 50 armored vehicles
, and forecasting they would
seek to capture at least one settlement in the sector before the fall campaign ends to establish a foothold for further offensive operations
— a modest goal short of the city itself. https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-05-18] Analyst commentary on Polymarket pricing described Dobropillia's status as positional/rear-area, noting
Currently, Dobropillia is not an immediate target of the assault; the battle is for the surrounding heights and strongholds. Although Dobropillia is located in the operational rear, it will only fall after the Ukrainian salient in the Pokrovsk area is completely eliminated
. https://maps.southfront.press/polymarket-bets-which-ukrainian-cities-will-hold-and-which-will-fall
- [2026-05-18] The same source noted market pricing at the time:
there is a 2% chance of capturing Dobropillia in May and a 10% chance in June
, indicating traders long treated near-term capture as unlikely. https://maps.southfront.press/polymarket-bets-which-ukrainian-cities-will-hold-and-which-will-fall
- [2026-01-05] A related Polymarket market ("Will Russia capture all of Donetsk Oblast," which requires Dobropillia among other cities) priced the December 31, 2026 outcome at only
"December 31" at just 4%
, reflecting low aggregate confidence in a Dobropillia-inclusive full-oblast capture this year. https://polymarket.com/event/will-russia-capture-all-of-donetsk-oblast-by
- [2026-06/07] A separate but similarly-defined market ("Will Russia enter Dobropillia by...?" — a lower bar, just entering rather than fully capturing) was priced much higher, at
Will Russia enter Dobropillia by...? ... 94% December 31
in one snapshot and
86% December 31
in another, showing traders expect Russian forces to enter/infiltrate parts of the city, but this is a distinct (lower) bar than the "capture" intersection in this question. https://polymarket.com/predictions/russia
- [2026-09/current] The specific "Will Russia capture Dobropillia by December 31" market (this question) is currently showing a low probability, listed at
Will Russia capture Dobropillia by...? ... 19% December 31
in the most recent aggregator snapshot found. https://polymarket.com/predictions/geopolitics
- [2026] Neighboring frontline city markets in the same "Ukraine Map" family show comparably low-to-moderate odds for capture-by-December-31 (e.g., Lyman 5%, Bilytske 71%, Chasiv Yar 59%), suggesting Dobropillia sits toward the low end of this reference class, consistent with its status as a secondary, heavily-defended objective rather than an active axis of advance. https://polymarket.com/predictions/ukraine-map
BOTTOM LINE: The outside view strongly favors "No": Dobropillia has already survived one full Russian offensive cycle (Aug–Nov 2025) that failed outright, comparable nearby cities (Pokrovsk) took ~19 months of grinding attrition before an ambiguous "capture," and current prediction-market pricing for this specific capture question sits around 19% — well below even, and far below related "entry" markets that use a much lower bar for resolution.
NOT FOUND: An exact, verified live price/timestamp for the specific Polymarket "Will Russia capture Dobropillia by December 31, 2026" market at the time of writing (only aggregator snapshots were available, with slightly differing dates); no independent poll or expert-panel probability estimate (outside of Polymarket/ISW) was found specifically for this event.
report: yes case
- [2026-07-24] A Russian forward group from the 2nd Combined Arms Army, supported by tanks and BMPs, already
entered and dug in on the eastern side of Dobropolye
, while assault units bypassed north and cut the Dobropillia–Kramatorsk road — showing Russian troops have physically been inside city limits since mid-summer 2026, not merely approaching it. https://tsarizm.com/news/eastern-europe/2026/07/24/russian-military-advances-near-dobropolye-dobropillia/
- [2026-09-18] ISW-sourced reporting (via Azov Corps commander Prokopenko) states Russia's offensive campaign in the sector
would peak in September 2026 and that Russian forces would begin changing tactics by October 2026, shifting toward mechanized breakthrough attempts
, giving a concrete near-term mechanism (armor-led breakthrough) rather than continued slow infiltration. https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-09-18] The same reporting quantifies the massed force: Russian units are being reinforced with
mechanized columns of about 50 armored vehicles to divert Ukrainian forces and increase the chances of a successful breakthrough
, and roughly 1,200 Rubicon drone crews are tied to the sector, indicating a materially larger combined-arms push than the 2025 infiltration-only offensive that failed. https://english.nv.ua/nation/russia-moves-armor-to-dobropillia-prepares-fall-mechanized-attacks-isw-50642532.html
- [2026-09-18] A Ukrainian military source is quoted describing the manpower imbalance on this specific axis as
a roughly 30-km-long front facing three Russian armies (8th, 41st, 51st) plus the 76th Airborne Division and naval infantry, with "The ratio is approximately one to six when comparing the numbers"
— a numerical disparity that, if sustained, could eventually overwhelm defenders despite drone-based attrition. https://euobserver.com/238150/russians-trying-to-capture-dobropillia-before-the-leaves-fall-from-the-trees-ukraine-battlefield-update-day-1666/
- [2026-09-18] The same report states explicitly that around
a third of all 1,200 Rubicon crews had been deployed there
, concentrating Russia's most effective drone-warfare asset specifically on Dobropillia rather than spreading it across the front, consistent with a deliberate priority target designation ahead of winter. https://euobserver.com/238150/russians-trying-to-capture-dobropillia-before-the-leaves-fall-from-the-trees-ukraine-battlefield-update-day-1666/
- [2026-09-18] Russian and Ukrainian sources converge on describing the goal explicitly as urban seizure before winter: the stated aim is
for Russian soldiers to infiltrate the city before the leaves fall in autumn, allowing them to conduct urban warfare there
, meaning Russia's own campaign timeline targets city entry within the market's remaining window (through December). https://euobserver.com/238150/russians-trying-to-capture-dobropillia-before-the-leaves-fall-from-the-trees-ukraine-battlefield-update-day-1666/
- [2026-07-25] A frontline reporting trip found access to Dobropillia had already degraded sharply by mid-2026:
as recently as spring it was still possible to drive into Dobropillia by armored vehicle, but logistics grew harder in early June when Russian forces reinforced the stretch with additional Rubicon and Sudny Den drone crews, signaling Dobropillia had become one of the main axes of the Russian advance
, and by the visit
"The logistics changed within two months. Now everything is on foot," with a real ordeal to reach the city
— indicating Ukrainian resupply/logistics into the city are already severely constrained, a precondition for eventual encirclement. https://frontliner.ua/en/line-of-contact-nears-dobropillia-city-isolated/
- [2026 (pre-Sept)] DeepState analysts themselves flagged the danger explicitly, warning that if Russian forces gained a foothold in villages near the Dobropillia–Kramatorsk road and pushed deeper,
"we could be looking at the possibility of Dobropillia falling sooner than Pokrovsk"
— a scenario forecast by Ukraine's own primary tracking source, not just Russian propaganda. https://www.yahoo.com/news/articles/russian-troops-advance-towards-dobropillia-173714133.html
- [2026-07-14] An FPRI analysis of Rubicon's operations notes that in the 2025 cycle, despite Ukraine stabilizing the salient, Russia
did manage to advance and occupy most of Pokrovsk and Myrnohrad during this time
using the same drone-and-infiltration playbook now being scaled up against Dobropillia, showing the tactic has previously produced full city capture (Pokrovsk) when sustained long enough. https://www.fpri.org/article/2026/06/inside-rubicon-the-structure-of-russias-elite-drone-center/
- [2026-09-22] Unverified pro-Russian aggregator claims allege the Russian MoD has announced Dobropillia "encircled," naming specific trapped Ukrainian units (4th & 15th Guard brigades, "Skala" regiment); while uncorroborated by ISW/DeepState, if even partially accurate this would represent the closest yet to the "captured" threshold, since ISW's resolution criteria count any Russian-controlled shading including "Assessed Russian Gains in the Past 24 Hours." https://www.military-stuff.org/massive-strike-dobropillia-encircled-ms-2026-09-22/
- [2026-02-25] The Pokrovsk precedent shows ISW can confirm a "capture" retroactively and abruptly once Ukrainian activity ceases inside a city, even after months of assessed stalemate — meaning a rapid map-status flip for Dobropillia is methodologically plausible without weeks of visible siege first, once Russian forces achieve sufficient local density.
BOTTOM LINE: The strongest YES path is Russia's fall 2026 mechanized offensive (armor, ~50 AFVs, a third of Rubicon's drone crews, 6:1 local force ratio) explicitly timed to seize a foothold or the city itself "before the leaves fall," combined with already-degraded Ukrainian logistics into Dobropillia and a forward Russian group already dug in on the city's eastern edge since July — if this mechanized push in October–November succeeds where 2025's infantry-only infiltration failed, an ISW capture designation before December 31 is plausible, especially given the precedent of Pokrovsk being confirmed "captured" abruptly once resistance ceased.
NOT FOUND: No primary ISW map snapshot or DeepState screenshot after September 21, 2026 could be retrieved to confirm current red-shading status at the exact coordinate; no confirmation of the September 22 Russian MoD "encirclement" claim from ISW, DeepState, or a mainstream outlet.
report: no case
- [2026-09-21] Per ISW's daily assessment, Russian forces averaged 32 attacks per day in the Dobropillia direction since August 1, yet
Ukrainian forces continue to hold positions in the Dobropillia direction in areas that Russian sources had previously claimed were captured by the Russian army
, showing that even Russia's own maximal claims lag well behind the "shaded red" bar this market requires. https://unn.ua/en/news/the-russian-army-failed-to-establish-a-foothold-near-dobropillia-despite-the-highest-rate-of-attacks-on-the-front-isw
- [2026-09-20/21] ISW-sourced reporting specifies the only confirmed penetration as an infiltration into "the southwestern part of Dobropillia" with
Russian attempts to advance in this area have not yet led to any significant confirmed gains
— and per the market's own resolution text, "Assessed Russian Infiltration Areas" explicitly do not qualify for a Yes resolution, meaning the most advanced confirmed Russian position inside the city currently fails the contract's own bar. https://ua.news/en/war-vs-rf/rosiiani-namagaiutsia-prorvati-oboronu-ukrayini-na-kilkokh-napriamkakh-isw
- [2026-09-21] ISW separately reported no confirmed Russian advances during Sept 19–20 across multiple other axes (Lyman, Kupiansk, northern Kharkiv/Sumy), indicating a front-wide stall rather than a Dobropillia-specific anomaly, consistent with an army that is over-extended rather than accelerating toward encirclement. https://unn.ua/en/news/the-russian-army-failed-to-establish-a-foothold-near-dobropillia-despite-the-highest-rate-of-attacks-on-the-front-isw
- [2026-09-22] RBC-Ukraine (ISW-sourced) confirms the pattern continuing one day later: in the Dobropillia direction Russian forces are still only "attempting to infiltrate in small groups," with
Ukrainian drones preventing them from consolidating their positions in captured areas, and despite the high tempo of attacks in this direction, Russian forces have made few confirmed gains there
— a second independent data point past the colleague reports' most recent date (Sept 21) showing no acceleration. https://newsukraine.rbc.ua/news/russian-troops-try-to-infiltrate-ukraine-1790063091.html
- [~2026-09] A separate secondary tracker (Hamerintel, reporting on war-days 1,641–1,647, i.e. roughly early-to-mid September) claimed Russian units had "established a presence inside the town" in Dobropillia's northern part and taken the suburb of Hannivka — but this is an unverified aggregator, not ISW/DeepState primary sourcing, and RBC/UNN's ISW-sourced Sept 21–22 reporting (which would supersede it) still frames only "infiltration," not confirmed control, and Hannivka was reported recaptured by Ukraine per colleagues' Sept 22 note. https://hamerintel.com/data/articles/16297
- [2026-09] Mezha's summer-campaign tally shows Russian gains front-wide markedly slower than 2025:
open-source analysts from DeepState and ISW assessed Russian forces captured between 235 and 270 square kilometers of Ukrainian territory over the summer, nearly four times less than during the same period in 2025
, undercutting the case that Russia's tempo is accelerating enough to seize a heavily defended city outright before year-end.
- [2026-09] The same source notes the autumn rasputitsa (mud season) is approaching, which
may reduce the effectiveness of Ukrainian reconnaissance and attack drones, creating additional opportunities for Russian forces
in the Dobropillia area — but this is double-edged: mud historically immobilizes armor and mechanized columns on both sides, and ISW's own Sept 17-18 assessment (per colleagues) says Russia is only now moving armor in preparation for a "fall mechanized push," meaning any mechanized breakthrough attempt would coincide with, not precede, the seasonal mobility constraint.
- [2026] The 2025 precedent remains directly on point: the original Dobropillia offensive ran over three and a half months (Aug 11–Nov 29, 2025) and
ended in status quo ante bellum with initial Russian gains reversed and all involved settlements returning to Ukrainian control
, and ISW's own contemporaneous reporting explicitly stated Russian infiltrations were "not taking control of the territory" — the same characterization ISW is using for the 2026 push as of Sept 21-22. https://en.wikipedia.org/wiki/Dobropillia_offensive
- [2026-09-15/18] Per colleagues, ISW assessed Ukraine's Operation Vivaldi counteroffensive had already disrupted Russia's broader fortress-belt encirclement plan; Prokopenko (Azov Corps) is only forecasting Russia will "capture at least one settlement in the sector" (not the city of Dobropillia itself) before the fall campaign ends — a modest goal explicitly short of the intersection this market requires.
- [2026] The specific "capture Dobropillia by Dec 31" market itself was priced around 19% in the most recent snapshot found by colleagues, and the related, easier-to-trigger "enter Dobropillia" market sits at 86-94% — the large gap between "enter" and "capture" pricing reflects trader consensus that infiltration (already arguably occurring per Sept 22 ISW reporting) is far more likely than the sustained, persisting-through-a-full-update-cycle red shading this contract requires.
- [2026-09-22] Unverified Russian MoD "encirclement" claims circulating via aggregator/video channels (already flagged by colleagues) remain uncorroborated by ISW, DeepState, or mainstream wire services as of the latest fetch; ISW's own Sept 21-22 daily reporting (via RBC and UNN) makes no mention of any encirclement and instead continues to describe Ukrainian forces holding positions and repelling infiltration, directly contradicting the encirclement narrative.
BOTTOM LINE: All primary-source-adjacent reporting through Sept 22, 2026 (two days newer than colleagues' latest ISW citation) shows Russia still confined to unconsolidated infiltration in Dobropillia's southwest/north fringes — a status the market's own rules exclude from "capture" — while the city has already survived one complete Aug–Nov 2025 offensive cycle that fully reversed, and Russia's fall push (armor, Rubicon drones) is only beginning as the mud season approaches, arguing strongly for continued status-quo inertia through year-end.
NOT FOUND: A dated ISW interactive-map screenshot or DeepState snapshot from after Sept 22, 2026 showing the exact coordinate's shading status; independent verification (beyond aggregator video channels) of the Sept 22 Russian MoD "encirclement" claim.

(0) No source shows the condition met; the resolution-source fetch could not render the ISW map, and ISW-sourced reporting from Sept 21-22 says Russia is limited to small-group infiltration in the southwest, which the rules exclude. YES needs red shading at the likely-central intersection, persisting through a full ISW update cycle. (a) About 14 weeks remain, to Dec 31, 2026. (b) Status quo is NO: ISW reports 32 attacks a day with only insignificant results, Hannivka reportedly recaptured, and Operation Vivaldi disrupting the fortress-belt envelopment. (c) NO: the fall mechanized push stalls in mud season and under drone attrition, repeating the 2025 offensive that ended status quo ante; Azov's Prokopenko expects only one settlement to fall, and summer gains were about four times smaller than in 2025. (d) YES: concentrated Rubicon drone crews and a claimed 6:1 ratio, plus foot-only Ukrainian logistics, let Russian groups consolidate from the city's edges until ISW abruptly assesses control, as with Pokrovsk. The Sept 22 MoD encirclement claims are aggregator-only and contradicted by ISW, so I discount them. The 21.5% anchor is broadly consistent with the October market (5.5%) and comparable December markets; I shade slightly lower given no acceleration in the freshest ISW reporting.

(0) Resolution check: the condition is not met. ISW-sourced reporting from Sept 21–22 (UNN, RBC-Ukraine) describes only small-group Russian infiltration into Dobropillia's southwestern fringes, and the rules explicitly exclude infiltration shading. The Sept 22 Russian MoD "encirclement" claim appears only on aggregator video channels and is uncorroborated by ISW or DeepState. (a) About 99 days remain until the Dec 31, 2026 deadline. (b) Status quo is No: the intersection is inside the city, not on its outer edge. Russia is averaging about 32 attacks a day without confirmed gains, and Ukraine's Operation Vivaldi has disrupted the broader encirclement plan. (c) NO scenario: the fall mechanized push is blunted by drones and the autumn mud season, as the Aug–Nov 2025 offensive was, which ended at status quo ante. Russia takes at most a nearby village, the modest goal Prokopenko forecast. (d) YES scenario: the armor build-up (about 50 armored vehicles, a third of Rubicon's drone crews, a reported 6:1 local force ratio), combined with already on-foot-only Ukrainian logistics, lets Russia consolidate inside the city by Nov–Dec. ISW would then shade advance polygons over the intersection, and ISW's advance shading can be generous. Anchor: Polymarket prices this at 21.5%, and the October-deadline sibling market is at 5.5%. Front-wide Russian tempo is about four times slower than in 2025, and Pokrovsk took about 19 months to fall, so I shade slightly below the market to about 16%.

(0) The resolution condition is not shown as already met: the interactive ISW map could not be read at the exact coordinate, but ISW-sourced reporting through September 22 describes only unconsolidated infiltration, which the rules expressly exclude, rather than qualifying Russian control. (a) Roughly 99 days remain until December 31, 2026, enough for a fall offensive but a short period in a sector where comparable urban captures have taken many months. (b) If nothing changes, the intersection remains under Ukrainian control and the market resolves No. (c) The No scenario is that Ukraine continues preventing Russian assault groups from consolidating, Operation Vivaldi holds its gains, and mud and attrition blunt the planned mechanized push through year-end. (d) The Yes scenario is that Russia's concentrated forces, approximately 50 armored vehicles and substantial Rubicon drone support achieve an October-November breakthrough, establish qualifying control over the intersection, and retain ISW red shading through the next update cycle. I anchor on Polymarket's 21.5% Yes price but shade it down to 19% because the newest ISW-sourced reports say Russia is averaging heavy attack activity without significant confirmed gains, while the 2025 offensive was fully reversed; uncertainty over the unreadable exact-coordinate map and Russia's evident buildup prevents a larger adjustment.

(0) The resolution condition is not shown as already met: the interactive ISW map could not be read at the exact coordinate, while ISW-sourced reporting through September 22 describes only unconsolidated infiltration and few confirmed gains, which the rules explicitly exclude. (a) About 99 days remain until December 31, 2026, so Russia would need to establish qualifying control over the intersection and have the shading persist through the next full ISW update cycle by then. (b) If nothing changes, the intersection remains under Ukrainian control and the market resolves No. (c) The No scenario is continued Ukrainian containment through the autumn mud and winter, resembling the failed 2025 offensive, with Russian infiltrators unable to consolidate despite a high assault tempo. (d) The Yes scenario is that Russia's planned fall mechanized push, supported by concentrated Rubicon drone units and a reported local manpower advantage, breaks Ukrainian logistics and secures the relevant part of Dobropillia before year-end. I anchor on Polymarket's 21.5% Yes price but shade it down to 19% because the latest ISW-sourced reports say Russia is not advancing significantly, Operation Vivaldi disrupted the broader plan, and the stated near-term Russian objective may be only one nearby settlement rather than Dobropillia itself; uncertainty about the unreadable exact ISW shading prevents a larger move.
