final rationale
Mean of 5 draws (0.31, 0.31, 0.32, 0.30, 0.33). (0) Nothing is resolved yet. The RIK homepage shows only commission sessions, with no results, and the vote is on 25 October 2026. (a) About 29 days remain until election day, and final seat counts would follow shortly after. (b) Status quo: the SNS-led 'Aleksandar Vučić – United Serbia' list leads in conventional polls. The latest is Faktor Plus, 16–20 Sept: 48.6% vs 37.1%. SNS has also won every national election since 2012. That points to No. (c) No scenario: Vučić resigns and campaigns full-time, and media asymmetry plus the registry and phantom-list mechanics help SNS. SNS then takes a plurality in line with the Faktor Plus and Ipsos numbers, as in 2023. (d) Yes scenario: near-total opposition consolidation behind the Student List holds and turnout surges. The independent CRTA polls prove right: July showed Students 44.9% vs 35.7%, and a reported 13–27 Sept for/against-government framing showed 57.9–42.1. The Student List then wins the most seats. The Polymarket anchor is 31%, with the Vučić list at ~66.5%. The only information that might be underpriced is the late-September CRTA figure. It is binary-framed and I found it only through Wikipedia, so it does not justify moving off the anchor against pro-government pollsters and a strong incumbent base rate. I stay at the market price.

This is a Polymarket election-winner market, so polymarket_direct is the price anchor and the sibling outcome markets (SNS list and others) help check consistency. Wikipedia's election page usually aggregates opinion polls for the student list vs SNS. Kalshi may have a parallel market for an independent price, and RIK is the resolution source.

report: current state
- [2026-09-09] President Vučić called snap parliamentary elections for 25 October 2026 and dissolved the National Assembly; the citizens' group "Student List – Students Are Winning" (Студентска листа – Студенти побеђују) was founded the same day. The association Student List was registered on 21 May 2026, and the citizens' group Student List – Students Are Winning was founded on 9 September 2026, the same day the 2026 parliamentary elections were called. - [2026-09-14/15] The Student List submitted its candidate list of 250 names (headed by cardiologist Ilija Srdanović) to the Republic Electoral Commission (RIK), which unanimously proclaimed the list, confirming 69,099 valid supporting signatures. Za proglašenje liste glasalo je svih 19 prisutnih članova RIK-a... Ona je rekla da je utvrđeno da izborna lista ispunjava uslove u pogledu zastupljenosti polova. - [2026-09-16/20] The most recent published poll (Faktor Plus, fieldwork Sep 16–20, published Sep 21) shows the SNS-led "Aleksandar Vučić – United Serbia" list at 48.6% vs Student List at 37.1%, SPS 4.9%, "European Serbia" 3.6%, with 16% undecided. A Faktor Plus poll, conducted from 16 to 20 September among 986 respondents, found that if elections were held on Sunday, the "Aleksandar Vučić – United Serbia" list would secure 48.6% of the vote, compared with 37.1% for the Student List. Two other lists would also cross the 3% electoral threshold: the Socialist Party of Serbia on 4.9% and the "European Serbia" coalition on 3.6%. Meanwhile, 16% of respondents remained undecided. - [2026-09-21] Analysis of the Faktor Plus polling series notes this agency has consistently favored SNS and shows the SNS-Student List gap widening since April 2026 (46.4–28.7 in April, 47.1–30.7 in June, 47.2–31.5 in early Sept, to 48.6–37.1 now) even as the student gap narrowed in absolute terms. The Faktor Plus has consistently weighed in favor of the SNS, for example... in April 2026, 46,4 percent for the SNS/Vučić list and 28,7 percent for the student list; in June, the ratio was 47,1–30,7 percent; and in early September, 47,2–31,5 percent, until we reached the current 48,6 percent. - [2026-07-15] By contrast, the CRTA/Stanford Democracy Action Lab poll (fieldwork June, published July 15) was the first regular poll since 2010 to show a non-SNS option leading: The survey, conducted in June by Serbia's CRTA election watchdog and Stanford University's Democracy Action Lab, found that among decided voters, 44.9% would support the Student List, compared with 35.7% for President Aleksandar Vučić's SNS. - [2026-08-30] BIRODI released an "electoral outcome model" (not a standard poll) estimating Student List at 48.5% vs SNS at 38.6%, based on 2012–present results, demographic shifts and turnout modeling. Studentska lista osvojila bi oko 48,5 odsto glasova... prema modelu procene mogućeg izbornog ishoda... Procenjeni raspon rezultata Studentske liste je od 45,9 do 51,1 odsto, SNS–Vučićeve liste od 36,3 do 40,9 odsto. This model is a scenario/estimate, explicitly not a conventional poll, and stands as an outlier favoring the Student List versus most conventional polls. - [2026-09-11 to 20] Polling agency NSPM (30 July) had shown SNS 37.5% vs Student List 39.6% (a rare student-list lead), while Ipsos and Faktor Plus consistently show SNS ahead; agencies disagree markedly, and opposition media accuse Ipsos/Faktor Plus of pro-government bias. The Opposition and independent media accuse polling agencies Ipsos and Faktor Plus of pro-government bias. - [2026-09-21] Analyst commentary attributes the Student List's polling gains partly to consolidation of opposition votes after several opposition parties withdrew from the race in its favor. Regarding the Students' List, Pejic said the withdrawal from the election race of the People's Movement of Serbia, Ecological Uprising, and New Face of Serbia had contributed to a consolidation of the opposition vote. - [2026-09-27] Vučić is scheduled to formally resign the presidency and campaign as a private citizen and PM candidate atop the SNS-led "United Serbia" list. Serbian President Aleksandar Vučić announced that he plans to resign on September 27. He added that he will then take part in the election campaign. - [2026-09-26] Analysis piece (IFIMES via Eurasia Review) frames three possible outcomes for the election: an SNS majority with Vučić as PM, SNS finishing first without a stable majority, or a "student/opposition surge," and notes the Student List has called for street mobilization after polls close on 25 October. Faktor Plus (16–20 Sept., n=986): that list 48.6%, Student List 37.1%... Warns against a "replay of the 1990s"; notes Student List calls to the street after polls close. - [2026-09-14] Student List leader Srdanović declined a proposed TV debate offer from Vučić, per Serbian press coverage. Vučić offered a TV debate; Srdanović declined. - [2026-09-25] Wikipedia's election article confirms the race dynamics: multiple opposition groups (PES coalition members SSP/SRCE/PSG) are cooperating with or deferring to the Student List, with PSG dropping out of its own coalition in September to back the students instead. PSG left the coalition in September, announcing that it wouldn't participate in the elections and would support the Student List instead. BOTTOM LINE: As of late September 2026, all recent conventional polls (Faktor Plus, Ipsos, NSPM average) show the SNS-led "Aleksandar Vučić – United Serbia" list ahead of the Student List, with the gap widening in the newest (Sep 16-20) Faktor Plus poll to 48.6% vs 37.1%; only CRTA (July) and the non-standard BIRODI scenario model (August) show the Student List ahead, and both are viewed by some as outliers or contested for methodology/bias reasons. The current state of polling therefore leans toward SNS's list finishing first, though the race is being described by analysts as more competitive than any Serbian election in over a decade, with meaningful uncertainty (~16% undecided) as of the last measured poll. NOT FOUND: No poll fieldwork later than 20 September 2026 was found (i.e., nothing from the last ~6 days before this report); no seat-projection/allocation model (as opposed to vote-share) specific to the Student List was located; the RIK's own official candidate/list count as of 26 September 2026 was not directly fetched from rik.parlament.gov.rs.
report: base rate
- [2026-09-26] Base rate reference class: SNS has won every parliamentary/general election in Serbia since 2012 (2012, 2014, 2016, 2017 snap, 2020, 2022, 2023), an unbroken 7-election streak of ~13-14 years of incumbent electoral victories. The 2026 election is the fourth early parliamentary election since the SNS came to power in 2012, none triggered by a collapse of the ruling majority but rather a strategic political move. https://www.ispionline.it/en/publication/serbias-election-results-vucics-sns-victory-amidst-vast-irregularities-157292 - [2023-12-17] Most recent precedent: in the 2023 election, the SNS-led list won 129/250 seats (48.06%) against a fragmented opposition (largest rival SPN got 65 seats), illustrating how dominant incumbent margins have historically been even against unified opposition coalitions. https://en.wikipedia.org/wiki/2023_Serbian_parliamentary_election - [2026-09-26] However, this cycle is a genuine outlier versus the base rate: CRTA's poll published on 15 July 2026 marked the first time any political option other than SNS took first place in a regular national poll since July 1st 2010, over 16 years prior. https://en.wikipedia.org/wiki/Opinion_polling_for_the_2026_Serbian_parliamentary_election - [2026-07-16] Independent (non-government-linked) pollster CRTA/Stanford DAL found among decided voters, 44.9% would support the Student List, compared with 35.7% for President Aleksandar Vučić's SNS , the first published poll ever to place a challenger ahead of SNS. https://www.intellinews.com/student-list-overtakes-serbia-s-ruling-sns-in-poll-ahead-of-expected-elections-455084/ - [2026-09-21] By contrast, government-aligned/traditionally pro-government pollster Faktor Plus (accused by opposition media of bias) put the SNS-led "United Serbia" list at 48.6% versus 37.1% for the Student List in its most recent survey (16-20 Sept), continuing a consistent SNS lead across nearly all Faktor Plus and Ipsos polls this cycle. The Opposition and independent media accuse polling agencies Ipsos and Faktor Plus of pro-government bias. https://www.bta.bg/en/news/balkans/1208852-poll-vucic-led-list-at-48-6-student-list-at-37-1-ahead-of-serbia-s-parliamen - [2026-09-26] Polling this cycle shows a wide agency-dependent split: government-leaning firms (Faktor Plus, Ipsos, Nacija TV) consistently show SNS leading 44-51% vs Student List 28-42%; independent/academic pollster CRTA shows Student List leading 44.9-57.9% vs SNS 35.7-42.1%. This divergence itself is a historically unusual feature (no prior Serbian cycle had such polarized "for/against government" framing). https://en.wikipedia.org/wiki/Opinion_polling_for_the_2026_Serbian_parliamentary_election - [2026-09-26] Prediction-market pricing across platforms currently favors the incumbent list: Polymarket's "Serbia Parliamentary Election Winner" market prices "Aleksandar Vučić – United Serbia" at 72%, followed by "Student List – Students Win" at 32% as of Sept 24-26, with a slight subsequent move to roughly 63-64% vs 37-38% by Sept 26. https://polymarket.com/event/serbia-parliamentary-election-winner-2026 - [2026-09-19] Kalshi's equivalent contract similarly prices "United Serbia" much higher (~95¢) than "Student list" (~86¢ combined across separate binary contracts), consistent with markets treating the incumbent list as the base-rate favorite despite unprecedented opposition polling strength. https://kalshi.com/markets/kxserbiaparli/serbian-parliamentary-election-winner/kxserbiaparli-26jun30 - [2026-09-26] Structural base-rate factors favoring incumbents in Serbia historically include: observers have assessed that Serbia has suffered from democratic backsliding into authoritarianism, followed by a decline in media freedom and civil liberties , and the V-Dem Institute has classified Serbia as an "electoral autocracy" since 2014 — conditions historically associated with incumbent overperformance relative to independent polling. https://en.wikipedia.org/wiki/2026_Serbian_parliamentary_election - [2026-09-26] Opposition-side base rate risk: the Student List is a newly formed, first-time citizens' group (association registered 21 May 2026, list founded 9 September 2026) with no prior electoral track record, unlike SNS's seven consecutive national victories; first-time/new movement lists in Serbia have not previously won a national plurality. https://en.wikipedia.org/wiki/Student_List - [2026-09-26] Track record of Serbian pro-government pollsters (Ipsos, Faktor Plus) has been criticized as biased toward overstating SNS support, while CRTA/independent polling has historically been viewed as more methodologically robust, though it has less of a multi-cycle track record for predicting final seat outcomes given Serbia's electoral-autocracy conditions (turnout manipulation, list withdrawal effects, etc.) https://en.wikipedia.org/wiki/Opinion_polling_for_the_2026_Serbian_parliamentary_election BOTTOM LINE: The historical base rate strongly favors the incumbent (SNS/"United Serbia" list has won every national election since 2012, often with 46-50%+ vote shares against fragmented opposition), and current prediction markets (Polymarket ~37-38%, Kalshi similar) still price the Student List as the underdog; however, this cycle is a genuine base-rate outlier, as independent pollster CRTA is the first in 16 years to show a non-SNS option leading, meaning historical priors should be weighted alongside — not simply substituted for — this cycle's unusually competitive and polarized polling picture. NOT FOUND: No official RIK-published poll-of-polls or seat projection was found; no historical instance of a first-time citizens'-group list winning a Serbian national plurality was found (making direct "success rate" for this specific reference class effectively undefined/zero-sample); could not find independent verification of Kalshi's exact current percentage split (only recent snapshot with mixed labels).
report: yes case
**Strongest YES case: mass, unprecedented civic mobilization consolidates the anti-SNS vote onto a single list, and the most methodologically independent pollster shows that consolidation still growing into late September.** - [2026-09-26] A newly-surfaced fieldwork window (13–27 September, n=2,020) from CRTA — the pollster whose July survey was the first in 16 years to show a non-SNS option leading — puts the "for/against government" scenario at Student List 57.9% vs SNS-led bloc 42.1%, a wider +15.8 lead than CRTA's own July poll (+9.2), directly contradicting the Faktor Plus narrative of a widening SNS lead. https://en.wikipedia.org/wiki/Opinion_polling_for_the_next_Serbian_parliamentary_election - [2026-07-30] NSPM — a "regular" (non-scenario) poll, not just CRTA's binary framing — separately put the Student List at 39.6% against SNS's 37.5%, making it a second independent house to show the students ahead at some point this cycle. https://en.wikipedia.org/wiki/Opinion_polling_for_the_next_Serbian_parliamentary_election - [2026-09-25/26] The list has consolidated an unusually broad coalition of formal backers — DS, ZLF, PSG, POKS, SPO, NPS, NLS, EU, Kreni-Promeni, the Social Democratic Party, LSV, Dveri and Enough is Enough all publicly support the Student List rather than running rival slates. The Student List received support from DS, ZLF, PSG, POKS, SPO, NPS, NLS, EU, Kreni-Promeni, Social Democratic Party, League of Social Democrats of Vojvodina, Dveri, and Enough is Enough, as well as from various local associations from Serbia and Kosovo. https://en.wikipedia.org/wiki/2026_Serbian_parliamentary_election - [2026-09-11] Grassroots energy translated into visible turnout at the campaign's opening event: hundreds gathered in Serbia's second city Novi Sad on Thursday evening for the first pre-election rally held by the student opposition movement ahead of early parliamentary elections , explicitly invoking the 2024 Novi Sad disaster as a mobilizing grievance. https://balkaninsight.com/2026/09/11/student-led-movement-launches-election-challenge-to-serbian-government/bi/ - [2026-09-11] Balkan Insight notes the structural strength of this challenger versus prior opposition attempts: the student movement has become the strongest opposition force in Serbia, and the decision to participate in the elections represents its first direct entry into electoral politics. https://balkaninsight.com/2026/09/11/student-led-movement-launches-election-challenge-to-serbian-government/bi/ - [2026-09-14] The signature-collection drive to qualify for the ballot moved unusually fast and drew large public participation: the list was submitted to the Republic Electoral Commission on 14 September 2026, after a march through central Belgrade, with around 70,000 signatures of support — far above the minimum threshold, evidencing organizational capacity for get-out-the-vote operations. https://en.wikipedia.org/wiki/Student_List - [2026-09-14] Vreme's campaign coverage frames the coalition's unifying logic explicitly around defeating the incumbent: "Studentska lista je okupila prilično heterogenu i veoma široku mrežu podrške," ujedinjuje ih procena da pojedinačne interese treba podrediti rušenju režima Aleksandra Vučića, a da su studenti jedina snaga koja to može da ostvari — i.e., disparate opposition actors have subordinated their own interests to the single goal of unseating SNS via the students, reducing vote-splitting relative to 2023's fragmented opposition. https://vreme.com/vesti/studenti-izbori-studentska-lista/ - [2026-09-20] Srdanović twice declined Vučić's televised debate challenge, per Vreme, a low-risk posture consistent with a front-runner protecting an existing lead rather than needing to contest ground. https://vreme.com/vesti/studenti-izbori-studentska-lista/ - [2026-09-13/14] Concrete evidence of opposition parties actively stepping aside rather than merely "declining to campaign": Koalicija Narodna Srbija koju čine Narodni pokret Miroslava Aleksića, Ekološki ustanak Aleksandra Jovanovića i Novo lice Srbije Miloša Parandilovića predala je potpise Republičkoj izbornoj komisiji i istovremeno povukla iz izborne kampanje , directly funneling their voters toward the Student List. https://www.danas.rs/vesti/politika/studenti-sutra-predaju-potpise-za-listu-organizuju-mars-podrske-od-rektorata/ - [2026-09-26] Analyst commentary (Eurasia Review/IFIMES) frames a genuine "student/opposition surge" as one of three live scenarios for October 25, alongside SNS majority or SNS plurality without a majority — meaning credible outside analysts still treat a Student List win as a plausible, not fringe, outcome this late in the race. https://www.eurasiareview.com/26092026-serbia-early-parliamentary-elections-a-test-of-political-legitimacy-and-future-direction-analysis/ BOTTOM LINE: The strongest YES path is that the Student List has achieved a scale of civic mobilization (mass rallies, ~70,000 signatures, near-total opposition-party consolidation) unmatched by any past Serbian challenger, and the most recent independent (CRTA) poll shows this translating into an even larger lead than in July, directly at odds with government-aligned pollsters — making a Student List plurality plausible if CRTA's methodology proves closer to the true electorate than Faktor Plus/Ipsos. NOT FOUND: No RIK-published turnout or seat-projection model was located; could not confirm the exact publication date of the CRTA 13–27 September fieldwork poll or find it on CRTA's own site (only via Wikipedia's aggregation); no seat-by-seat translation of any 2026 poll into projected National Assembly seats was found.
report: no case
- [2026-09-21] A sitting RIK election commissioner, Sofija Mandić (CEPRIS), publicly warned that the 2026 vote will be "irregular" whoever wins, citing a persistent gap of over 900,000 people between census adult population and the registered electoral roll, an unresolved structural risk carried over from 2023. https://streamlinefeed.co.ke/news/serbian-election-commissioner-warns-2026-vote-marred-by-phantom-voter-discrepancies - [2026-09-21] The same commissioner flagged that a legislative change now lets a single citizen sign in support of multiple electoral lists, enabling "phantom lists" that "legalised proliferation of phantom political lists, a member of the Republic Electoral Commission (RIK) has warned" — a mechanism that dilutes the anti-SNS vote across more fringe lists, working against Student List consolidation even amid the reported opposition-withdrawal trend. - [2026-09-26] Structural tilt persists into this cycle: analysts note that while there has been no proof of major vote-counting irregularities, the playing field before election day has been heavily tilted in favour of the ruling party, with the OSCE/ODIHR noting the "ruling party's systemic advantages" in prior cycles — a pattern with no evidence of correction for 2026. - [2026-09-26] Pro-government tabloid media (Informer, largest-circulation daily) has run a sustained discrediting campaign against the Student List's candidates and program in the two weeks after its RIK proclamation, including claims the list has no coherent policy positions on Kosovo, the EU, or Srebrenica — indicating an asymmetric media environment still favoring the incumbent list in the final month. https://informer.rs/politika/vesti/1151315/opozicija-blokaderi-izbori - [2026-09-27 planned] Vučić's resignation and full-time campaigning as a private citizen, with a campaign visiting the most remote parts of Serbia and three or four large rallies in Kragujevac, Belgrade, Novi Sad and Niš , signals the incumbent apparatus is mobilizing maximal late-campaign resources rather than coasting — a sign SNS itself does not treat the race as safely won, undercutting any narrative of inevitable Student List momentum. - [2026-09-26] The Student List itself has visible internal strain: reporting describes a "prilično velika migracija glasova sa strane opozicionih partija ka studentskoj listi" occurring largely as tactical consolidation rather than affirmative enthusiasm, and separate Mašina reporting notes unresolved friction such as a dispute between the party center and a local (Vranje) committee over whether to back the list, suggesting coordination is not fully settled a month before polling. - [2026-09-25] Local-election dynamics from the same cycle (10 municipalities, 29 March 2026) show the opposition/students did not always unify behind a single list — in some municipalities they ran separately, illustrating that even the vaunted "opposition consolidation" behind Student List is uneven and incomplete at lower levels, a potential drag on national list discipline and turnout efficiency on 25 October. - [2026-09-26] No conventional (methodologically standard, house-disclosed) poll fielded after 20 September has shown the Student List ahead; the most recent Faktor Plus survey (16–20 Sept, n=986) instead shows the gap widening to 48.6% vs 37.1%, continuing a multi-month trend rather than reversing it. - [2026-09-26] Deadline arithmetic favors NO on ambiguity grounds: the market only resolves "Other" if results are not "definitively known" by 31 March 2027, but disputes over the 900,000-voter discrepancy and phantom lists (flagged by an RIK commissioner) create a plausible post-election contestation pathway similar to the 2023 fraud allegations and protests, which could delay a definitive resolution without changing which list leads. - [2026-09-26] Historical precedent for post-election opposition delegitimization efforts (2023 "Serbia Against Violence" protests demanding annulment) shows that even strong opposition showings have not previously translated into overturning an SNS plurality; the Student List's own stated plan to mobilize street protests after polls close (per IFIMES analysis) echoes a pattern that in 2023 did not change the seat outcome. BOTTOM LINE: The NO case rests less on top-line polling (which colleagues already covered) and more on structural mechanics that persistently favor the incumbent list: an acknowledged ~900,000-voter registry gap, a newly legalized "phantom list" loophole that fragments the anti-SNS vote, continued media asymmetry, unresolved coordination friction inside the Student List coalition, and a track record in which even a mobilized opposition (2022, 2023) has never converted street pressure or narrowing polls into an outright seat-plurality defeat of SNS. NOT FOUND: No RIK-published official candidate/list count or seat-projection model was directly retrieved from rik.parlament.gov.rs; no post-20-September conventional poll (as opposed to commentary/analysis pieces) was found; no confirmed instance of the "Narodna Srbija" list actually withdrawing per Mandić's suggestion.

(0) Nothing is resolved yet. The RIK homepage shows only commission sessions, with no results, and the vote is on 25 October 2026. (a) About 29 days remain until election day, and final seat counts would follow shortly after. (b) Status quo: the SNS-led 'Aleksandar Vučić – United Serbia' list leads in conventional polls. The latest is Faktor Plus, 16–20 Sept: 48.6% vs 37.1%. SNS has also won every national election since 2012. That points to No. (c) No scenario: Vučić resigns and campaigns full-time, and media asymmetry plus the registry and phantom-list mechanics help SNS. SNS then takes a plurality in line with the Faktor Plus and Ipsos numbers, as in 2023. (d) Yes scenario: near-total opposition consolidation behind the Student List holds and turnout surges. The independent CRTA polls prove right: July showed Students 44.9% vs 35.7%, and a reported 13–27 Sept for/against-government framing showed 57.9–42.1. The Student List then wins the most seats. The Polymarket anchor is 31%, with the Vučić list at ~66.5%. The only information that might be underpriced is the late-September CRTA figure. It is binary-framed and I found it only through Wikipedia, so it does not justify moving off the anchor against pro-government pollsters and a strong incumbent base rate. I stay at the market price.

(0) Nothing is resolved yet. The RIK homepage shows only commission-session news and no results; the election is on 25 October 2026. (a) About one month remains until the vote. Official results should come shortly after, well before the 31 March 2027 'Other' cutoff. (b) If nothing changes, most polls from firms seen as pro-government (Faktor Plus 16–20 Sept: 48.6% for the SNS list vs 37.1% for the Student List; Ipsos) put Vučić's United Serbia list first. SNS has also won all seven national elections since 2012, which points to No. (c) NO scenario: SNS's structural advantages decide the race. These include media asymmetry, the ~900k gap between the census adult population and the voter roll flagged by an RIK commissioner, and Vučić resigning to campaign full-time. United Serbia takes a plurality, much as the pro-government pollsters show. (d) YES scenario: independent polling is closer to the truth. CRTA showed the Student List leading 44.9–35.7 in June, and a reported 13–27 Sept 'for/against' scenario had it at 57.9–42.1, though its dating is unverifiable and it is a binary framing. Near-total opposition consolidation behind the list (withdrawals by Narodna Srbija, PSG and others) plus high turnout among young and urban voters then carries it to first place. The Polymarket anchor is 31%, with the complementary Vučić market at 66.5%. Pollster disagreement is real, but I see no unpriced information strong enough to move off the consensus, so I stay near 31%.

(0) The condition is not yet met. The RIK site shows only commission-session notices, and the vote is on 25 October 2026. (a) That leaves about one month, with the result then due in RIK's official seat allocation. (b) On the status quo, the conventional polls read as an SNS plurality. Faktor Plus (16–20 Sept) has 'Aleksandar Vučić – United Serbia' at 48.6% against 37.1% for the Student List, and Ipsos agrees. SNS has won seven straight national elections since 2012. Serbia is an 'electoral autocracy' with a roughly 900k-voter registry gap and heavy media asymmetry. (c) NO: Vučić resigns and campaigns full-time, the state and media apparatus plus the phantom-list loophole blunt the students' consolidation, and SNS wins more seats as the house polls predict. (d) YES: near-total opposition consolidation behind the students and mass mobilization hold up. Independent pollsters (CRTA's July 44.9–35.7 lead, NSPM's 39.6–37.5) prove right over the government-leaning houses, and the Student List edges out SNS on seats. A reported CRTA poll showing 57.9–42.1 has a fieldwork window ending after today and a binary framing, so I treat it as unverified and discount it. The Polymarket anchor is 31% and has drifted down from 41%; the companion Vučić list trades around 66.5%. I see no unpriced information strong enough to move far, so I stay near the market with a slight nudge up, given how split the pollsters are.

(0) The condition has not been met: the Republic Electoral Commission homepage, updated September 25, contains no results or seat totals, so the Student List must win the most seats in the October 25 election, with definitive results required by March 31, 2027. (a) There are 29 days until election day and the market close. (b) If current conditions persist, NO wins: the latest completed conventional poll, Faktor Plus fielded September 16–20, has United Serbia ahead 48.6% to 37.1%, while SNS has won every Serbian parliamentary election since 2012. (c) A straightforward NO scenario is that Vučić's campaign, incumbent media and organizational advantages, and opposition fragmentation preserve even part of that polling lead, leaving United Serbia with the most seats. (d) YES occurs if broad opposition consolidation and unusually strong student mobilization produce turnout closer to the independent CRTA and NSPM measurements, which have shown the Student List ahead. I anchor on Polymarket's 31% YES price and shade it only slightly to 30% because the purported September 13–27 CRTA poll is potentially important but is not yet verified on CRTA's site and its fieldwork extends beyond today, while the incumbent's base-rate and latest conventional-poll advantages remain substantial.

(0) The condition has not already been met: the Republic Electoral Commission homepage, updated September 25, contains no results or seat allocations, so the Student List must finish first in seats in the October 25 election. (a) There are 29 days until election day and the market close, leaving meaningful time for campaigning and undecided voters to shift. (b) If the current balance persists, NO wins: the latest completed conventional poll, Faktor Plus fielded September 16–20, has United Serbia ahead 48.6% to 37.1%, while SNS has won every Serbian national election since 2012. (c) A straightforward NO scenario is that Vučić's campaign, incumbency, media advantages, and electoral machinery preserve even a reduced SNS lead, giving United Serbia the most seats. (d) YES occurs if broad opposition consolidation and student-led mobilization produce the electorate indicated by CRTA and NSPM, allowing the Student List to overtake SNS in votes and seats. I anchor on Polymarket's 31% YES price and move only slightly upward to 33% because the Student List's extensive coalition support and independent polling provide a credible upset path, while the purported September 13–27 CRTA result is unconfirmed at its primary source and cannot outweigh the latest conventional poll and strong incumbent base rate.
