final rationale
Mean of 2 draws (0.17, 0.16). (0) Resolution check: the condition is not met. Reporting from 13–16 Oct 2026 (Al Jazeera, Reuters, CFR, Iran International) shows the Islamic Republic governing under Mojtaba Khamenei. The IRGC, Supreme Court and Supreme National Security Council are all functioning, and the crackdown is ongoing. (a) About 14.5 months remain until 31 Dec 2027. (b) Status quo is No. The regime has already absorbed Ali Khamenei's assassination, a US-Israeli war, a naval blockade and the January mass uprising, with no independently reported security-force defections. Under the rules, an IRGC-dominated hollowing-out or another succession does not count. (c) No scenario: the regime 'North Koreanizes'. It stays poorer and more repressive, with the IRGC running things behind an invisible Supreme Leader, and post-midterm US strikes degrade it without producing an internal break. (d) Yes scenario: 90% inflation and a rial near 2.7m per dollar trigger a renewed nationwide uprising after the midterms. IRGC or Basij units refuse to fire or split, possibly after a second decapitation strike, and a provisional authority displaces the clerical structures. Anchor and adjustment: this market sits at 23% on only about $19.6k of volume. The deep sibling 'fall before 2027' market ($27M) is at 5.5%, which implies the market puts roughly 18% on collapse during calendar 2027 alone. That is high next to low historical hazard rates for revolutionary autocracies and the repeated pattern of crisis-driven overpricing on this question ladder. The broader 'leadership change by June 30, 2027' market sits at only 23.5%, and that market counts mere succession events. Long-dated thin markets also carry a Yes premium from capital lockup. I shade below the market to about 17%, keeping a substantial tail for war escalation and economic collapse.

It could be helped by a second decapitation strike or an armed peripheral front. Each step lacks evidence today, and the IRGC has consolidated rather than fractured, so this case needs several unproven steps within about 14 months. - no case: The regime has already survived the strongest shocks one could design: the Supreme Leader killed, a US-Israeli campaign, a blockade and mass protests. It did so with no reported security-force defections, no organized alternative, and a resolution test that excludes leadership change and IRGC-led continuity. Reaching Dec 2027 therefore requires a new elite split or mass uprising that has not yet shown up.

report: current state
- [2026-10-15] The Islamic Republic still governs. Supreme Leader Mojtaba Khamenei has held the post since March 2026. Reuters, CFR and Iran International reports through 15–16 Oct show no collapse. Iran's army chief says Hormuz stays closed, and the IRGC says it is ready on all fronts. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-15] Netanyahu adviser Ophir Falk said Israel is "very close" to creating conditions for regime change through military and economic pressure. He added that regime change is "up to the Iranian people". This is an Israeli claim, not an observed outcome. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-15] US Treasury imposed new sanctions on 16 individuals and 10 entities under "Operation Economic Outcast". Bessent said the "noose is tightening" on Iran's economy. A US naval blockade is in force. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-15] CBS and CNN report the White House and Pentagon have prepared options to use the GBU-43 "mother of all bombs" on Iran. Reported targets include military sites, energy infrastructure and nuclear sites. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-08] Trump pledged no US strikes on Iran before the 3 Nov midterms. On 1 Oct he called new strikes after the midterms "possible". The pledge was still standing as of 14 Oct. https://www.cfr.org/global-conflict-tracker/conflict/confrontation-between-united-states-and-iran - [2026-10-15] Trump said peace might have been easier if the US had not removed so many Iranian leaders. He also said the US eliminated Iran's nuclear capability. https://www.foxnews.com/live-news/us-iran-war-peace-donald-trump-strait-hormuz-oil-prices-midterms-october-15 - [2026-10-05] Talks are stalled. Araghchi says there is "no military solution" and Tehran has seven conditions for reopening Hormuz. Trump rejected Iran's seven-point proposal. Qatar says indirect talks continue (6 Oct). The June 17 MOU broke down and fighting resumed 8 July. https://www.dawn.com/news/2034846 - [2026-10-16] Iran's military capacity is degraded but not gone. Israeli media report its missile-launcher force is back to at least 400, against 420 before the war. At least 10 ships were struck in and around Hormuz from 11–15 Oct, a war-time high. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-08] Internal control is intact and repressive. An AP-syndicated report describes a wartime crackdown on protesters at home and abroad, and executions continue. This follows the January 2026 nationwide protests, in which Western officials said at least 2,000 were killed. https://www.detroitnews.com/story/news/world/2026/10/08/irans-wartime-hunt-protesters-home-abroad-ushers-in-new-era-repression/92155495007/ - [2026-10-05] Protests are currently sectoral, not a mass uprising. NCRI (opposition-aligned) reports retiree protests in several cities on 4–5 Oct. Unknown attackers killed security personnel in Sistan-Baluchestan around 14 Oct. https://www.ncr-iran.org/en/ncri-statements/statement-iran-protests-by-retirees-and-other-sectors-against-plundering-and-repression-in-various-cities/ - [2026-10] Economic strain is severe. Pezeshkian said the regime has never faced such pressure in 48 years. Food aid is being widened to about 40 million people. https://www.yahoo.com/news/world/articles/irans-president-says-islamic-regime-144440631.html - [2026-03-01 to 2026-08-10] Leadership has been replaced but the structures persist. An Interim Leadership Council ran from 1 March. Mojtaba Khamenei was elected on 8 March, and the IRGC and top officials pledged allegiance. Ali Abdollahi became armed forces chief of staff on 10 Aug, and Mohsen Rezaei became Supreme National Security Council secretary on 9 Aug. As of 21 May, Mojtaba was reported to be in hiding. https://en.wikipedia.org/wiki/2026_Iran_war BOTTOM LINE: As of 16 Oct 2026 the Islamic Republic's core structures are intact, with a new Supreme Leader, a functioning IRGC and an active crackdown, and nothing indicates imminent collapse. Heavy external pressure (war, blockade, sanctions) and a dire economy keep the tail risk elevated. Trump's no-strike pledge runs only to 3 Nov, so renewed US strikes after the midterms are a live possibility. NOT FOUND: any consensus report of regime collapse or loss of control over most of the population. Also not found: a dated scheduled event before 2028 that would trigger a transition, apart from the 3 Nov US midterms. I did not get a fetched copy of GlobalSecurity (HTTP 402). I also found no confirmed recent public appearance by Mojtaba Khamenei.
report: base rate
- [2026-10-16] Sibling Polymarket market "fall before 2027" (end-2026 deadline) showed 6% Yes on the fetched page. It has $27.2M volume. The page notes the regime has held through the Khamenei assassination and the US-Israeli strikes, and that US intelligence sees no imminent collapse. The page also lists a "before 2028" market (this contract) and a "by June 30, 2027" market, with no prices shown in the fetched text. https://polymarket.com/event/will-the-iranian-regime-fall-by-the-end-of-2026 - [2026-09-01] Octagon AI's model put the end-2026 fall at 7%, matching the market at 7%. It rated the regime resilient despite sanctions and the 2025/26 crisis. This is an automated report, with a Trust Index of 47 (high risk) and a note that the market was thinly traded at that point. https://www.octagonai.co/markets/reza-pahlavi/iran-regime/will-the-iranian-regime-fall-before-2027 - [2026-08/09] A Dimers snapshot, about 48 days old, showed the end-2026 market at 8% Yes. https://www.dimers.com/industry/news/will-the-iranian-regime-fall-before-2027-live-odds-and-polymarket-predictions - Track record of the sibling ladder: every earlier Polymarket deadline resolved No. These were Mar 31, Apr 30, May 31 and Jun 30, 2026, plus the 2025 market. The Mar 31, Apr 30 and Jun 30 markets had $52M–$66M in volume each. https://polymarket.com/event/will-the-iranian-regime-fall-by-june-30 ; https://polymarket.com/event/will-the-iranian-regime-fall-by-april-30 - [2026-01 approx.] The end-2026 market spiked to about 39% during the Dec 2025–Jan 2026 protests, then fell to 13% by early April and 6–7% by Sept–Oct. Spikes during crises have repeatedly proved overpriced. The Tribuna figure is a press report. https://tribuna.com/en/betting/blogs/prediction-markets-see-surge-in-bets-on-iran-amid-protests-a/ - [2026-03-04] A Manifold market, "Will Iran's regime fall in 2026?", sat at about 4%. Its resolution requires both that core institutions are dissolved and that the regime has lost control of the majority of the population. https://manifold.markets/SaviorofPlant/will-irans-regime-fall-in-2026 - [2026-03-11] Reuters, as cited by a secondary source, reported US intelligence assessing that the Iranian government is not at risk of collapse, with the IRGC and interim leadership holding control. I did not open the Reuters piece. https://www.infosalam.com/en/geopolitics/studies/will-the-iranian-regime-fall - [2026-02-05] Johns Hopkins SAIS expert Narges Bajoghli saw no signs of imminent collapse. The House of Commons Library says analysts largely judged the regime likely to survive the Jan 2026 protests, though it is now much weaker. The Britannica entry says the protests were suppressed without fracture within the regime. https://washingtondc.jhu.edu/news/what-to-know-about-iran-february-2026/ ; https://commonslibrary.parliament.uk/research-briefings/cbp-10462/ - Reference class, which is academic and dated: Geddes–Wright–Frantz data on autocratic breakdowns cover 1946–2010. The only figure I could confirm is the average length of the Eastern European communist regimes, 34 years. The Iranian regime is about 47 years old and was born in a violent social revolution. A World Politics study of regimes from 1900 to 2015 finds such regimes especially durable. Typical annual hazard rates for autocracies are low single digits. I did not find a figure in the sources, so that is my recollection rather than a verified number. https://www.cambridge.org/core/journals/world-politics/article/abs/social-revolution-and-authoritarian-durability/B62A931E63978E8B8466225EC123D2A9 ; https://pages.ucsd.edu/~mnaoi/page4/POLI227/files/page1_11.pdf - Single-party regimes are more vulnerable to economic crisis. Iran's rial is near record lows and inflation is surging. https://eppam.weebly.com/uploads/5/5/6/2/5562069/authoritarianbreakdown_geddes.pdf - [2026-10-07] Officials, including judiciary chief Mohseni-Ejei on Oct 5, increasingly describe economic stress as a security threat. The NCRI, an opposition group and a partisan source, reports factional feuds eroding Mojtaba Khamenei's authority, ongoing executions, and scattered retiree and worker protests. There are no reports of mass defections or a new uprising. https://www.ncr-iran.org/en/news/economy/iranian-regimes-judiciary-warns-against-angering-the-public-amid-economic-stress/ ; https://www.ncrius.org/irans-regime-fears-another-uprising-as-economic-crisis-deepens.html - Chenoweth's 3.5% rule says a sustained nonviolent campaign involving 3.5% of the population has historically succeeded. Iran's Jan 2026 protests were crushed, with 3,117 deaths per the state-funded Martyrs Foundation and "several thousand" per Khamenei. Reaching and sustaining that level is the open question. https://cmarmitage.substack.com/p/coalition-collapse-four-frameworks ; https://commonslibrary.parliament.uk/research-briefings/cbp-10462/ BOTTOM LINE: Historical hazard rates for entrenched revolutionary autocracies are low, and every Polymarket deadline so far has resolved No, including through a war, a leader's assassination and mass protests. The market priced end-2026 collapse at about 6–7% in Sept–Oct 2026. The extra 12 months to Dec 2027 plausibly adds some probability, but I found no direct price for this "before 2028" contract. NOT FOUND: The current price of the "before 2028" and "by June 30, 2027" contracts. Any Metaculus, Good Judgment or Kalshi forecast on Iranian regime change. A verified quantitative annual breakdown rate for autocracies from the Geddes data. Expert probability estimates beyond qualitative assessments.
report: yes case
YES means: the Islamic Republic's core structures (Supreme Leader's office, Guardian Council, IRGC under clerical authority) are overthrown, collapsed or replaced by a fundamentally different system, or lose de facto control over most of Iran's population, by 31 Dec 2027 (11:59 PM ET). - [2026-10-03] The most likely YES path is a slow economic squeeze that ends in a security-force split. Inflation and the currency are the strongest new numbers behind it. The Statistical Center of Iran put year-on-year inflation at a record 89.8%. The rial passed 2.5m per dollar, so the 166m-rial minimum wage is worth about $66. Hardline MPs are blaming the Central Bank and threatening impeachments. Iran International analysts call it a "slow meltdown" that "may not bring it down soon". https://www.iranintl.com/en/202610028912 - [2026-10-03] The US campaign is widening. Sanctions were extended to Iran's auto and rail sectors on top of the naval blockade. The $2bn banknote injection by the Central Bank failed to stop the rial's slide. Bessent says the pressure is working. The inflation and currency data show the pressure is real; they do not show a political break. https://www.iranintl.com/en/202610028912 - [2026-04-28] Reuters reported that the system has no single clerical arbiter any more. IRGC commanders and the Supreme National Security Council decide, and Mojtaba Khamenei mainly legitimizes their decisions. A Pakistani mediator said decisions can take 2–3 days. For YES, this means the clerical apex is hollow, but the same report found no fracture or street opposition nine weeks into the war. https://www.timesofisrael.com/irgc-shores-up-wartime-power-in-iran-blunting-supreme-leaders-role/ - [2026-10-03] The southeast is an active insurgency. Haalvsh reported hours-long fights in Rask and Zahedan and a roadside bomb that killed IRGC-linked Fatemiyoun fighters. It said the armed side includes the People's Fighters Front, a Baluch alliance formed in late 2025. The IRGC disputes the casualty accounts. Haalvsh could not verify the toll independently. This is peripheral erosion, and under the criteria it counts only if the state stops administering most of the population. https://www.iranintl.com/en/202610028912 - [2026-10-16] Kurdish fronts exist but are small. Clashes between PJAK's armed wing and the IRGC began in early June 2026 near Marivan and Mahabad. ACLED recorded more assassinations of IRGC affiliates. Kurdish groups stayed relatively passive in the war. The Kurdish groups' own commanders called a US-backed offensive exaggerated in April, and the PDKI says it is waiting for a popular uprising. https://en.wikipedia.org/wiki/Western_Iran_clashes_(2026%E2%80%93present) ; https://www.thenationalnews.com/news/mena/2026/04/02/why-a-ground-offensive-by-iranian-kurds-against-the-regime-never-materialised-and-why-it-still-could/ - [2026-10-04] Sectoral unrest is widening. Retirees marched in five cities and students sat in at Tehran. Steel retirees chanted that the enemy "is right here", not America. Oil Minister leadership changed abruptly, and officials warned of winter blackouts. Parliament Speaker Ghalibaf made upgrading police a "definite priority". That signals regime fear of unrest. The report is from the NCRI-linked outlet Bytes Europe, which is partisan. https://www.byteseu.com/2423881/ - [2026-10-07] Regime-friendly and analyst voices now frame bread prices as the main threat. The rial hit about 2.72m per dollar on 4 Oct. An opposition source cites food inflation above 121%. Both figures are NCRI-sourced and unverified. https://www.ncr-iran.org/en/news/iran-news-in-brief-october-7-2026/ ; https://de.ncr-iran.org/proteste-demonstration-im-iran/rial-fallt-auf-268-500-abgeordneter-warnt-vor-folgen-der-drogenkrise-gaslieferungen-sinken/ - [2026-03] The elite is demonstrably vulnerable to decapitation. The opening strike killed Ali Khamenei and wounded Mojtaba, who has not appeared publicly (NYT via ToI, about April; NCRI says seven months' invisibility as of 15 Oct). A second decapitation, or Mojtaba's death or incapacity, would hit an already hollow clerical apex. The IRGC succeeded in naming a successor within days in March. A repeat would likely again produce an internal succession, which the criteria exclude. https://www.timesofisrael.com/liveblog_entry/report-irgc-generals-effectively-ruling-iran-sidelining-supreme-leader-mojtaba-khamenei/ ; https://www.ncrius.org/mojtaba-khamenei-stature-eroding.html - [2026-01-09] The Commons Library recorded that the Dec 2025–Jan 2026 protests reached all 31 provinces, including typically loyal areas, and that the rial halved between July 2024 and March 2025. The protests' stated goals included overthrowing the government. They were crushed by mass killing and internet shutdown. A repeat needs a security force that refuses to shoot, and none has yet. https://commonslibrary.parliament.uk/research-briefings/cbp-10456/ - [2026-03-11] The Hill, citing Reuters, reported the US intelligence view that the regime was not in danger of collapse and still controlled the public. The source added that the situation was fluid. https://thehill.com/policy/international/5782102-iran-regime-collapse-unlikely/ - [2026-01 to 2026] Expert opinion splits on the YES case. Hudson (Doran) says the regime lacks only an organized revolutionary leadership, and that elite fracture, security defection or external intervention could supply the catalyst. MEI says collapse is likely but democracy is not. Stimson says the opposition cannot defeat loyal forces without foreign intervention. https://www.hudson.org/foreign-policy/ayatollahs-regime-crumbling-michael-doran ; https://mei.edu/commentary/irans-coming-reckoning-regime-collapse-is-likely-democracy-is-not/ ; https://www.stimson.org/2026/what-would-be-indicators-of-regime-collapse-in-iran/ - [2026-03-12] The MEF "cascading desertions" claim (about March) and the NCRI's claims of 20 "resistance unit operations" on 8 Oct are partisan. No independent source shows mass defections. https://www.meforum.org/mef-reports/the-shortest-way-through ; https://www.ncr-iran.org/en/news/iran-news-in-brief-october-8-2026/ BOTTOM LINE: The single most likely YES path is a combined squeeze: blockade and sanctions plus about 90% inflation and a record-low rial, followed by a mass uprising after the US midterms in which IRGC or Basij units refuse to fire or split. It could be helped by a second decapitation strike or an armed peripheral front. Each step lacks evidence today, and the IRGC has consolidated rather than fractured, so this case needs several unproven steps within about 14 months. NOT FOUND: any independent, non-partisan report of IRGC or army unit defections, any confirmed mass-protest resumption in October, a dated trigger before 2028 beyond the 3 Nov midterms, or a credible forecaster (Metaculus, Good Judgment) probability for collapse by end-2027.
report: no case
YES means: the Islamic Republic is overthrown, collapses, or otherwise ceases to govern (core structures dissolved or replaced, or it loses control of most of Iran's population) by 31 Dec 2027, 11:59 PM ET. - [2026-10-09] The Congressional Research Service, as relayed by defense.info, finds no organized opposition able to threaten the regime and judges collapse not imminent. This is a US government analytic view. The same piece says the regime survived the decapitation of the leadership on 28 Feb. It also reports that Iran Human Rights counted 4,219 killed in the Dec–Jan protests and that more than 6,000 were arrested after the war began. The author sees the likely path as a poorer, hollowed-out state that survives, which he calls "North Koreanization" or "Houthization". https://defense.info/highlight-of-the-week/iran-after-seven-months-of-war-a-balance-sheet/ - [2026-10-09] Mojtaba Khamenei reportedly governs by handwritten orders sent by courier, has not appeared in public, and is reportedly badly injured (per the CRS). The UK House of Commons Library notes analysts' view that Iran has moved to shared leadership with a larger IRGC role. Under the resolution rules, leadership succession and internal power shifts that keep the core structures do not count. A weak or invisible leader, or an IRGC-dominated state, therefore resolves NO. https://defense.info/highlight-of-the-week/iran-after-seven-months-of-war-a-balance-sheet/ - [2026-10-09] The economic damage is a pressure that has not turned into a loss of control. Iran loaded no crude in September, annual inflation is about 90%, and the economy is shrinking. The same source notes that "a regime can survive hunger for a long time". Elite fracture, not hardship, is the missing trigger. https://defense.info/highlight-of-the-week/iran-after-seven-months-of-war-a-balance-sheet/ - [2026-10-07] The rial fell to about 2.7 million per dollar. The central bank is selling up to $2B in cash dollars, and officials are publicly arguing over who is to blame. This is elite quarrelling over policy, not defection. The bazaar and inflation shocks of Dec 2025–Jan 2026 were already extreme (rial at 1.44M), and the regime still crushed the protests. Currency collapse alone has not produced regime collapse. https://www.iranintl.com/en/202610076990 - [2026-03-31] The CSMonitor quotes AGSIW's Ali Alfoneh as seeing no security-force defections. He says nationalism has kept the armed forces cohesive, and that the coercive institutions are performing better than in the past. The war has produced rally effects and has not split the security forces. https://www.csmonitor.com/World/Middle-East/2026/0331/iran-war-irgc-basij-intimidation-protests - [2026-06-09] Arab News reported that Polymarket's end-2027 collapse price fell from 55% on 28 Feb to 13% by 8 June. A rapid-fall expectation was stripped out within about 100 days despite decapitation, war and blockade. This is a track record of crisis-driven overpricing. The same piece quotes Chatham House's Sanam Vakil saying the regime is "quite clear" to be surviving. It also says US intelligence found Iran had repaired 30 of 33 Hormuz missile sites by mid-May. https://www.arabnews.com/node/2646579/middle-east - [2026-07 to 2026-10] The opposition has no organized presence inside Iran. Reuters found no mass organized movement ready to bring Pahlavi to power (per EU Reporter, 8 Oct). Modern Diplomacy (28 Jul) notes that exile coalitions have repeatedly collapsed. Without a replacement structure, even a large shock is more likely to end in an IRGC-led successor. That successor would be an internal power shift that does not count as a YES. https://www.eureporter.co/world/iran/2026/10/08/irans-false-alternative-and-why-tehran-benefits/ ; https://moderndiplomacy.eu/2026/07/28/can-reza-pahlavi-lead-regime-change-in-iran/ - [2026-06 approx.] Just Security argues that even Mojtaba's death would probably entrench the IRGC. It adds that the opposition is fractured and that the regime can simply outwait waning US commitment. The IRGC's "mosaic defense" disperses authority so that leaders can be killed and the organization still functions (JPost op-ed). Decapitation has already been tested and did not produce collapse. https://www.justsecurity.org/133945/entrenchment-iran-security-state/ ; https://www.jpost.com/opinion/article-892700 - [2026-10-09] Foreign pressure faces limits. The Pentagon has been told to prepare options for after 3 Nov. The same source says Iran has retained a real capacity to regenerate missiles, and US munitions and interceptor stocks are strained. It also says a renewed campaign "without a political end state" adds costs without settling the Iranian side. Air power has not toppled a regime without a ground or internal force. Washington's own shortfalls, and the midterm politics of a costly war, cap how long and how hard pressure can run. https://defense.info/highlight-of-the-week/iran-after-seven-months-of-war-a-balance-sheet/ - [2026-10] Resolution technicalities favor NO. The criteria require a "broad consensus" of reporting on a clear break in continuity, with loss of control over a majority of the population. Partial territorial loss, rebel or exile challenges, a leader's death, an IRGC takeover, or a "North Korea-style" hollowing out all fail the test. The sibling market's note that US intelligence sees no imminent collapse and the Manifold market's stricter two-part test point the same way. https://polymarket.com/event/will-the-iranian-regime-fall-by-the-end-of-2026 - [2026-09] The analytic consensus is "weaker but not defeated". Arab Center DC argues that devastating the economy will not break the regime, given geographic depth, evasion networks and repression capacity. MEI says it is structurally conditioned for endurance and unlikely to collapse rapidly. China's continued oil purchases are named as the key variable that could blunt the blockade. https://arabcenterdc.org/resource/why-devastating-iran-s-economy-will-not-break-the-regime/ ; https://mei.edu/policymemo/irans-economic-realities-amid-war/ - [2026-10-12] AFP's reporting from Tehran's bazaar shows the downturn is hitting the very merchants who backed the state. It describes hardship and lament, with no organized action. Opposition-aligned NCRI counts 201 sectoral protest actions in a month. That is chronic, dispersed protest of the kind the regime has absorbed repeatedly, below the nationwide January level. https://www.malaymail.com/news/life/2026/10/12/we-arent-meant-to-just-exist-iranians-lament-soaring-costs-as-inflation-bites/238665 ; https://www.ncr-iran.org/en/news/iran-news-in-brief-october-8-2026/ BOTTOM LINE: The regime has already survived the strongest shocks one could design: the Supreme Leader killed, a US-Israeli campaign, a blockade and mass protests. It did so with no reported security-force defections, no organized alternative, and a resolution test that excludes leadership change and IRGC-led continuity. Reaching Dec 2027 therefore requires a new elite split or mass uprising that has not yet shown up. NOT FOUND: A dated trigger event before 2028 other than the 3 Nov midterms and post-midterm US options. Any report of IRGC or Basij defections. A quantitative annual hazard rate for revolutionary autocracies I could verify. A current price for the "before 2028" contract (not searched, per instructions).

(0) Resolution check: the condition is not met. Reporting from 13–16 Oct 2026 (Al Jazeera, Reuters, CFR, Iran International) shows the Islamic Republic governing under Mojtaba Khamenei. The IRGC, Supreme Court and Supreme National Security Council are all functioning, and the crackdown is ongoing. (a) About 14.5 months remain until 31 Dec 2027. (b) Status quo is No. The regime has already absorbed Ali Khamenei's assassination, a US-Israeli war, a naval blockade and the January mass uprising, with no independently reported security-force defections. Under the rules, an IRGC-dominated hollowing-out or another succession does not count. (c) No scenario: the regime 'North Koreanizes'. It stays poorer and more repressive, with the IRGC running things behind an invisible Supreme Leader, and post-midterm US strikes degrade it without producing an internal break. (d) Yes scenario: 90% inflation and a rial near 2.7m per dollar trigger a renewed nationwide uprising after the midterms. IRGC or Basij units refuse to fire or split, possibly after a second decapitation strike, and a provisional authority displaces the clerical structures. Anchor and adjustment: this market sits at 23% on only about $19.6k of volume. The deep sibling 'fall before 2027' market ($27M) is at 5.5%, which implies the market puts roughly 18% on collapse during calendar 2027 alone. That is high next to low historical hazard rates for revolutionary autocracies and the repeated pattern of crisis-driven overpricing on this question ladder. The broader 'leadership change by June 30, 2027' market sits at only 23.5%, and that market counts mere succession events. Long-dated thin markets also carry a Yes premium from capital lockup. I shade below the market to about 17%, keeping a substantial tail for war escalation and economic collapse.

(0) The condition is not met. Reporting from Al Jazeera, Reuters, CFR and Iran International through Oct 14–16, 2026 shows the Islamic Republic still governing: Mojtaba Khamenei is Supreme Leader, the IRGC is operating, the courts are issuing death sentences and the crackdown continues. (a) About 14.5 months remain until Dec 31, 2027. (b) If nothing changes, the result is No. The regime has already survived the killing of Ali Khamenei, a US-Israeli war, a blockade and the January mass uprising, with no independently reported security-force defections. (c) No scenario: Iran becomes a poorer, IRGC-dominated, 'North Koreanized' state. Mojtaba's death or an IRGC takeover would count only as a succession or internal power shift, which the rules exclude. (d) Yes scenario: post-midterm US strikes, possibly including another decapitation, plus 90% inflation and a rial near 2.7m per dollar trigger a renewed nationwide uprising. Security units refuse to fire and a provisional government emerges. The market anchor is 23%, but this contract is thin, at about $20k volume. The deep sibling markets look inconsistent with it: 'fall before 2027' is at 5.5% on $27M, and the much broader 'leadership change by June 30, 2027', which includes successions that don't count here, is at 23.5%. An end-2027 market was also reportedly at 13% in June. Low base rates for durable revolutionary regimes and repeated crisis overpricing in this market ladder point the same way. I shade down to about 16%, keeping elevated tail risk for the war and economic collapse.
