Iran agrees to end enrichment of uranium by July 31?

Platform comparison

Market context

Iran would have to make a public commitment to stop all uranium enrichment by 31 July 2026 for this market to settle **Yes**; absent that, it resolves **No**. The crowd’s 30% implied probability sits against a backdrop of long-running escalation: Iran has repeatedly expanded enrichment after the JCPOA unravelled, including abandoning JCPOA limits in January 2020 and later enriching to 20% and 60%, while the IAEA has continued to flag concern over stockpile growth and reduced transparency.[1][2][3]

Historical read-through matters here because prior bargaining has tended to centre on *limits* rather than a full end to enrichment. Under the JCPOA, Iran accepted strict caps, inspections, and restrictions on centrifuges, but recent talks have reportedly stalled on the core question of whether enrichment can continue on Iranian soil at all.[3][4] That makes a clean pledge to end enrichment materially harder than a partial rollback, which helps explain why the market does not price this as a high-probability outcome.

The main catalysts are diplomatic announcements, not technical milestones. Traders should watch for any U.S.-Iran or Iran-IAEA statement, Oman-mediated meeting, or public shift in Tehran’s “red line” on domestic enrichment.[4] Since settlement depends on a public agreement, even a unilateral Iranian pledge would count if it appears before the deadline. For a market like this, funding flows can matter: easier deposits, low-friction rails such as SEPA or Klarna, and fast withdrawals in USDC typically widen participation and can deepen the book when headline risk spikes around talks or sanctions announcements.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
