Trade: Iran nuclear test before 2027?
Resolution criteria on PolyGram: This market will resolve to "Yes" if Iran conducts a nuclear test by December 31, 2026 11:59pm ET. Otherwise, this market will resolve to "No". A nuclear test is defined as the intentional non-combat detonation of a device by Iran that produces a nuclear chain reaction (fission or fusion), regardless of yield. Accidents, radiological dispersal devices (bombs that spread radioactive material using conventional explosives such as "dirty bombs"), or actions by third parties will not count toward this market's resolution. Tests not explicitly claimed by Iran may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to Iran.
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 outcomes
| Iran nuclear test before 2027? | 9% YES | 91% NO |
Market context
Iran conducting a nuclear weapons test before the end of 2026 represents a significant escalation from its current nuclear posture. The Islamic Republic has developed substantial uranium enrichment capabilities and possesses fissile material stocks, yet has not detonated a nuclear device since the 1979 revolution. The current 9% implied probability on Polymarket reflects a low but non-negligible tail risk, with the order book pricing in meaningful uncertainty around Iranian decision-making over the next two years.
Historical precedent suggests nuclear tests follow extended periods of technical preparation and political calculation. Pakistan conducted its first test in 1998 after roughly two decades of weapons development; North Korea waited until 2006 despite possessing fissile material earlier. Iran's nuclear programme has advanced significantly since the 2015 JCPOA, but moving from latent capability to an actual test represents a qualitatively different commitment. The 9% probability reflects scepticism that Iran would cross this threshold within the compressed timeframe, given the severe international consequences and the absence of clear technical necessity for a test to validate existing designs.
Near-term catalysts include ongoing International Atomic Energy Agency inspections, negotiations around potential nuclear agreements, and developments in US-Iran relations following leadership transitions. The IAEA's quarterly reports on Iranian enrichment levels and stockpiles provide concrete data points. Geopolitical escalation in the Middle East, particularly involving Israel or US military posturing, could alter incentive structures. Traders should monitor statements from Iranian nuclear officials and any sudden changes in enrichment activities or facility operations that might signal test preparations.

How active is this market?
$190K in lifetime turnover and $19K of resting liquidity puts this market in the above the median by volume for politics contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
Last 24 hours alone saw $170 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 6 months — long enough that the order book is mature and price is well-anchored to fundamentals.
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.

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.
