GPT-5.6 Luna

38% yes

Probably not — a ceasefire persisting through the midterms requires avoiding any U.S.-initiated air or surface-to-surface strike on Iranian territory for over two weeks, and ceasefires in a live U.S.-Iran confrontation are vulnerable to rapid escalation. The narrow definition excludes many incidents, but a major retaliation, miscalculation, or intelligence-driven strike could still qualify; the main uncertainty is whether current diplomacy successfully contains such events.

Claude Sonnet 5

92% yes

Likely yes — the June 2025 ceasefire has held for months with no new US strikes on Iran, and current diplomatic signals don't suggest imminent escalation before the midterms. Main risk is a sudden crisis (e.g., Iranian nuclear breakout or proxy attack triggering US retaliation) that could prompt a new strike before Nov 3.

Gemini 3.8 Flash

93% yes

Likely yes — there is only about two and a half weeks until the resolution deadline and direct US airstrikes or cruise missile strikes targeting mainland Iranian territory remain an exceptionally high escalation threshold that Washington actively avoids. The US typically retaliates against Iranian proxies outside Iran rather than directly striking sovereign Iranian soil. A sudden regional crisis resulting in mass American casualties directly traced to Iran could force an immediate direct strike, which is the primary downside risk.

Grok 4.6

82% yes

Likely yes — ceasefire holds through the midterms. With only ~17 days remaining and a ceasefire already in place, a US-initiated air or surface-to-surface strike that actually impacts Iranian territory is a low-probability event unless a major new trigger occurs. The main thing that could prove this wrong is a sudden Iranian attack on US or Israeli assets that prompts an immediate US retaliatory strike before 3 November.

DeepSeek V4 Pro

72% yes

Likely yes — the US has maintained a de facto ceasefire with Iran through most of 2025-2026, and there are no strong signals of imminent direct strikes. The narrow definition of qualifying action (excluding naval, artillery, and intercepted munitions) makes a 'No' resolution harder. The main risk is a sudden escalation from Iran-backed attacks on US forces prompting a direct US air strike before the midterms.

Qwen 3.8 Max

75% yes

Likely yes — a ceasefire already in place has momentum, and the ~17-day window until the midterms is relatively short for a deliberate escalation decision of this magnitude. Direct strikes on Iranian territory require high-level political authorization, and with midterms imminent, the political cost of breaking a ceasefire is significant. The main risk is an unexpected provocation or incident that forces a rapid retaliatory response.

Mistral Medium 3.5

75% yes

Likely yes — The US and Iran have historically avoided direct military confrontation, and a ceasefire would likely hold through the midterms to prevent escalation. A major US strike on Iran could still occur if tensions spike abruptly.

Kimi K3

72% yes

Likely yes — the question presupposes a US-Iran ceasefire is in place in October 2026, and ceasefires typically hold for at least a few weeks absent a major provocation, and the resolution bar is specific (US-initiated air or missile strikes directly impacting Iranian territory, excluding interceptions, drones like FPVs, artillery, and naval fire). The window is only ~17 days, and even amid tensions the US has historically preferred sanctions, cyber, and proxy pressure over direct strikes on Iranian soil, which risk major escalation. Main risk: an Israeli strike on Iranian nuclear facilities or a high-casualty proxy attack on US forces could trigger US retaliatory strikes before November 3.

GLM 5.3

12% yes

Likely yes — the US-Iran ceasefire has held since mid-2025 and there is no obvious near-term trigger for a renewed US air or missile strike on Iranian territory in the final weeks before the midterms. A strike right before the election would be politically costly, and the resolution rules exclude many minor actions (intercepted munitions, naval fire, small drones). The main risk is a sudden Iranian provocation or nuclear breakout news forcing a US response.

MiMo V2.5 Pro

82% yes

Likely yes — the ceasefire has held this long and the resolution criteria are narrow, requiring actual US air strikes or surface-to-surface missiles hitting Iranian terrestrial territory, excluding intercepted munitions, cyber ops, and artillery. With only about 2.5 weeks remaining and midterm domestic politics favoring restraint, a dramatic escalation to direct strikes on Iran seems unlikely. The main risk is an unexpected major Iranian provocation that forces a US kinetic response beyond cyber or proxy channels.

Resolution rules
This market will resolve to “No” if the United States takes a qualifying military action against Iran by November 3, 2026, 11:59 PM ET. Otherwise this market will resolve to “Yes.” A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by the United States, that directly impacts Iran. An air strike includes bombs, air-to-surface missiles, and air-launched drones. A surface-to-surface missile strike includes one-way attack drones and surface-to-surface missiles such as cruise or ballistic missiles. The following actions do not constitute a qualifying military action: Munitions destroyed or intercepted before impact; Surface-to-air missile strikes; Small-arms fire; Ground incursions; Cyber operations; Naval gunfire and artillery fire; Howitzers, artillery pieces, mortars, and rocket artillery (e.g. MLRS systems); Minor surface-to-surface strikes, including short range loitering munitions, FPV drones, and ATGM strikes; Any threat, authorization, or announcement of force that has not been executed. Any munition that is intercepted or destroyed before impact does not constitute a qualifying military action. Debris, fragments, or any wreckage from intercepted munitions that land on Iran do not constitute a military action regardless of any damage incurred. “Iran” refers to the terrestrial territory of Iran, including its internal waters. Iran’s maritime territory and airspace are not encompassed. Where territorial borders are disputed, all territory claimed by and under the de facto control of Iran as of market creation will qualify. The occurrence, attribution, and timing of a qualifying military action will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, attribution, or timing of a relevant military action, this market will remain open until the earlier of: i) the confirmation of the occurrence, attribution, and timing of the action based on a consensus of information available from the resolution sources or ii) 3 full calendar days (Iran Standard Time) from the date of the first credibly reported evidence of the action. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. At the end of the third calendar day, if conflicting reports remain, the incident will be adjudicated based on the totality of information available from the resoluti...
