Polymarket keeps Iran regime-fall odds at 2.45% as ceasefire rift flares

Polymarket Holds “No” Near 98% After US–Iran Ceasefire MoU Headlines

Polymarket traders are pricing a very low chance that Iran’s regime falls by Sept. 30, with “No” leading at 97.55% on about $278,895 in volume. The latest catalyst in headlines is a new flare-up in US–Iran ceasefire messaging, and the market reaction is best read through the contract’s binary settlement and the still-flat short-term odds.

Key Takeaways

• Polymarket implies “No” at 97.55% (Yes 2.45%) on whether the Iranian regime falls by Sept. 30.
• After the ceasefire MoU headline, pricing still reflects strong skepticism of near-term regime collapse rather than a meaningful repricing.
• Resolution is scheduled for 2026-09-30, and the market’s 24h and 7d changes are both 0.0 pp in the provided summary.

A report says President Trump declared the Memorandum of Understanding underpinning the US–Iran ceasefire “over,” making the remarks at a NATO summit in Turkiye. The same report says the US bombed Iran after previously promising a pause tied to Supreme Leader Ali Khamenei’s funeral.

Odds & Liquidity Check: “No” 97.55% vs “Yes” 2.45% on ~$278,895 Volume With 0.0 pp Moves (24h/7d)

This is a binary Polymarket contract: buying “Yes” only pays if the Iranian regime is judged to have fallen by the Sept. 30 resolution date; otherwise “No” wins, which is why the board is dominated by “No” at 97.55% versus “Yes” at 2.45%. Despite the headline catalyst, the provided historical summary shows a neutral trend with weak momentum, low volatility, and stable consensus, alongside 0.0 pp moves over both 24 hours and 7 days—signals of limited disagreement and no visible repricing impulse in the sampled window. The odds snapshot also points the same way: “No” is the leading outcome by a wide margin even as total volume sits around $278,895, suggesting activity has not translated into a higher implied probability of regime collapse. The key practical read is that Polymarket is functioning as a continuously updating probability gauge here, but at these levels the market is effectively saying any catalyst would need to be far more decisive to move the needle before the Sept. 30 settlement cutoff.

Watch whether “Yes” can sustain any bid above the low-single-digit range and whether volume accelerates into a directional move; absent that, the market is signaling a durable baseline expectation of “No” into the Sept. 30 resolution window.

Beyond this headline contract, traders often triangulate broader risk by watching neighboring Polymarket markets that can reprice faster on leadership, diplomatic milestones, and real-economy disruption. Right now that includes 83.25% on “Iran leader end of 2026?” (leading: Mojtaba Khamenei) on $19,832,425 volume, 37.5% on “US-Iran Final Nuclear Deal by…?” (leading: December 31) on $8,900,947, 30.0% on “Iran full airspace closure by…?” (leading: August 31) on $2,005,523, and 95.5% on “Strait of Hormuz traffic returns to normal by July 31?” (leading: No) on $13,592,607—each offering a different lens on how fast sentiment can shift across the same theme.
