Trade: U.S. x Iran Military Engagement by...?
Resolution criteria on PolyGram: This market will resolve to "Yes" if there is a military engagement between the military forces of the United States of America and Iran between market creation and the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". A "military engagement" is defined as any incident involving the use of force such as missile strikes, artillery fire, exchange of gunfire, or other forms of direct military engagement between US and Iranian military forces. Non-violent actions, such as warning shots, artillery fire into uninhabited areas, or missile launches that land in territorial waters or pass through airspace, will not qualify for a "Yes" resolution.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Market context
The question concerns whether direct military engagement between United States and Iranian forces will occur within the next eighteen months, through June 2026. This encompasses any use of force meeting the threshold of missile strikes, artillery fire, or exchange of gunfire between the two militaries, excluding warning shots or strikes in uninhabited areas. The current order book on Polymarket reflects a 100% implied probability, suggesting traders assess the likelihood as near-certain.
Historical precedent offers mixed signals for interpreting this extreme probability. The January 2020 Iranian ballistic missile strikes on Al Asad airbase in Iraq represented direct Iranian retaliation for the Soleimani assassination, yet neither side escalated further despite the kinetic exchange. Conversely, the 1988 USS Vincennes incident and various naval confrontations in the Strait of Hormuz demonstrate how miscalculation or accident can trigger unintended escalation. The 2019-2020 period saw sustained tensions without full-scale engagement, suggesting both parties have maintained implicit red lines despite provocations.
Traders should monitor several near-term catalysts. The trajectory of negotiations regarding the Joint Comprehensive Plan of Action remains consequential; any formal collapse could shift Iranian calculus. Regional proxy activities—particularly Houthi attacks on shipping and Israeli operations in Lebanon and Gaza—create secondary escalation pathways. Announcements regarding US military posture in the Gulf, Iranian nuclear programme developments, and statements from Iranian leadership, particularly Supreme Leader Khamenei, warrant close attention. Recent reporting from Reuters and AP News has highlighted increased Iranian military exercises and rhetoric, though these have historically preceded rather than guaranteed direct engagement.

How active is this market?
$315K in lifetime turnover and $0 of resting liquidity puts this market in the top 10% by volume for khamenei contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 4 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
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.
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.
