Trade: US-Iran nuclear deal by June 30?
Resolution criteria on PolyGram: This market will resolve to "Yes" if an official agreement over Iranian nuclear research and/or nuclear weapon development, defined as a publicly announced mutual agreement, is reached between the United States and Iran by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. If such an agreement is officially reached before the resolution date, this market will resolve to "Yes", regardless of if/when the agreement goes into effect. Agreements that include the United States and Iran as parties, even if they also involve other countries (e.g., a multilateral deal like the JCPOA), will qualify for 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 hinges on whether the United States and Iran will announce a formal nuclear agreement by end-June 2026. This encompasses any bilateral or multilateral deal addressing Iranian nuclear research or weapons development, provided both nations are signatories and the agreement is publicly announced before the settlement deadline. The current order book on Polymarket reflects a 34% implied probability, suggesting traders assess a roughly one-in-three chance of a deal materialising within the next 18 months.
Historical precedent offers mixed signals for interpreting this probability. The Joint Comprehensive Plan of Action (JCPOA) in 2015 took roughly two years of intensive negotiations following the interim agreement of 2013. However, the Trump administration's 2018 withdrawal and subsequent Iranian nuclear escalation have substantially raised the negotiating baseline. Previous attempts at rapprochement have foundered on verification protocols, sanctions relief sequencing, and regional security concerns. The current geopolitical environment—including ongoing Israeli-Iranian tensions and shifting US domestic politics—differs markedly from 2015 conditions.
Traders should monitor several near-term catalysts. Any formal resumption of talks between US and Iranian delegations, whether direct or through intermediaries, would signal meaningful movement. Announcements regarding sanctions relief frameworks or technical working groups on enrichment limits would suggest substantive progress. The US presidential transition in January 2025 represents a critical juncture; the incoming administration's Iran policy stance will largely determine negotiating appetite. Regional developments, particularly escalations involving Israel or proxy forces, could either accelerate talks as a stabilisation mechanism or derail them entirely.

How active is this market?
$4.5M in lifetime turnover and $197K of resting liquidity puts this market in the top 2% by volume for middle east contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $346K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for 6 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.
- CLOB
- 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.
