Resolution criteria on PolyGram: This market will resolve to “Yes” if the U.S. officially announces an extension of the ceasefire agreement between the U.S. and Iran, defined as a publicly announced commitment to the continued halt of direct military engagement with Iran or announces a new peace agreement, ceasefire framework, or diplomatic agreement under which the ceasefire will continue by the specified date 11:59 PM ET. Otherwise, this market will resolve to "No". If a qualifying announcement is officially made before the resolution date, this market will resolve to “Yes,” regardless of whether the ceasefire extension ultimately takes effect. A qualifying announcement requires clear public confirmation from the U.S.
Election and policy markets historically tighten as polling firms publish their final round and prediction-market traders fade or back the consensus. Current odds favour the YES side at 76%, making this a directional market, backed by $161K of resting liquidity.

The market is pricing the likelihood that the United States will publicly announce an extension or new framework for a ceasefire with Iran by 11:59 PM ET on the specified date. The 86% implied probability on Polymarket's order book reflects substantial confidence in such an announcement occurring, though the exact mechanics—whether through formal agreement, joint statement, or diplomatic framework—remain unspecified in the resolution criteria.
Historical precedent suggests caution when interpreting high probabilities on Iran-related diplomatic outcomes. The 2015 Joint Comprehensive Plan of Action (JCPOA) took months of intensive negotiation before announcement, whilst the Trump administration's subsequent withdrawal demonstrated how rapidly such arrangements can reverse. More recently, the November 2024 ceasefire between Israel and Hezbollah, brokered with US involvement, showed that regional agreements can materialise quickly when political conditions align, though durability remains contested. The current probability may reflect either genuine diplomatic momentum or market overconfidence in announcement timing.
Key catalysts include statements from the State Department, any scheduled diplomatic meetings between US and Iranian officials, and developments in broader Middle Eastern tensions that could either accelerate or derail negotiations. Recent reporting on US-Iran backchannel communications and any public signals from the incoming administration regarding Iran policy will materially shift trader positioning. The resolution hinges on an official announcement rather than substantive ceasefire maintenance, meaning even symbolic or preliminary agreements could trigger a "Yes" resolution, which may explain the elevated probability relative to the likelihood of durable peace arrangements.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
Most PolyGram markets clear winning USDC to traders within a few hours of the resolution date, gated only by the UMA optimistic oracle's two-hour dispute window.
If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.
Political markets occasionally see longer settlement when outcomes hinge on official certification rather than the polling result itself — the proposer waits for the certifying body's announcement, which can push payout 12-48 hours past the calendar end-date. Funds clear directly to your in-app USDC balance on Polygon. Withdrawals are non-custodial: send to any address you control, typical confirmation under 30 seconds, gas paid in USDC if you'd rather not hold MATIC.
Minimum order size on PolyGram is $1.00, with no maximum cap aside from available book depth. Orders route into Polymarket's on-chain CLOB on Polygon; the matching engine pairs YES buyers with NO buyers atomically — every executed trade is settled on-chain with no counterparty risk. For "US announces new Iran agreement/ceasefire extension?", political markets often see book depth concentrate in the 24-48 hours after a debate or policy event — spreads can widen to 3-5¢ for a few minutes after breaking news while makers re-price.
The trade ticket includes a slippage box (default 2%, configurable 0.1%-10%) that caps the worst-case entry price. Your maximum loss is your stake — winning YES (or NO) shares pay $1.00 each at resolution. With this market's current book depth ($161K of resting liquidity), a $500 order should fill with single-cent slippage at the displayed mid-price.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "US announces new Iran agreement/ceasefire extension?", the considerations above apply directly — Political markets are exposed to information asymmetry between insider and retail traders, and to last-minute polling shifts that can move the line 15-20¢ in the final 48 hours. Long-dated political contracts also carry meaningful time decay if the underlying race is close.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
