Market context
The underlying question concerns whether the Trump administration will accept Iranian uranium enrichment as part of any diplomatic settlement by mid-2026. This differs materially from the 2015 Joint Comprehensive Plan of Action (JCPOA), which permitted enrichment only under strict International Atomic Energy Agency monitoring and capped uranium purity at 3.65 per cent. The current market resolves affirmatively if the US agrees to any continued enrichment right—including those with caps, monitoring, or time limits—provided no blanket prohibition is imposed. Iran currently enriches uranium to 60 per cent purity, well above civilian reactor needs, following its 2018 withdrawal from the JCPOA after the Trump administration's initial exit.
Historical precedent suggests low probability for such acceptance. The first Trump term (2017–2021) pursued maximum pressure sanctions rather than enrichment concessions; the Biden administration similarly rejected Iranian enrichment above JCPOA levels. No sitting US administration has formally accepted Iranian enrichment rights without reciprocal constraints since the JCPOA's negotiation. The 18 per cent crowd probability reflects this structural resistance, though it acknowledges non-zero diplomatic risk should broader geopolitical realignment occur.
Key catalysts include any formal US–Iran negotiations announcement, IAEA board statements on Iranian nuclear activity, and statements from Trump's State Department or special envoys on nuclear policy. The Strait of Hormuz category frames this within energy-security implications; roughly 21 per cent of global petroleum transits the waterway, making Iranian nuclear capability a material factor in regional stability assessments that could influence negotiating positions through 2026.

Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket Legal UK triggers a quick verification flow that finishes in minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
