Iran agrees to surrender enriched uranium stockpile by 2026?

Market context

Iran would have to publicly agree to surrender its enriched uranium stockpile by 31 March 2026 for this market to pay out, and the crowd is pricing that at 0% Yes. That makes No the clear favourite, with the consensus implying traders see essentially no realistic path to a formal Iranian pledge in the near term. The market is a straight bet on diplomatic breakthrough rather than on covert movement of material: even if there were technical discussions, the wording requires a public Iranian agreement to transfer, ship or otherwise hand over any amount of stockpile.

The closest historical frame is the 2015 nuclear deal process, when Iran agreed to limit enrichment and accept tighter monitoring in return for sanctions relief, but did not surrender its stockpile in the way this market requires. Arms Control Association timelines show how much earlier nuclear diplomacy focused on caps, inspections and storage arrangements rather than an outright transfer of enriched uranium. That history argues for the underdog case: unless pressure is matched by a credible reciprocal package, a public surrender pledge is a much higher bar than most nuclear understandings. The value question, if any, sits against the 0% implied price, but only if one thinks the market is underweighting a rare, text-heavy bargain.

The main catalysts are official statements from Tehran, Washington and, if involved, Jerusalem, plus any announced talks or written framework emerging from U.S.-Iran contacts. Polymarket’s related uranium-possession market underscores how traders are already watching for any nuclear-linked announcement from the U.S. side, but for this event the key trigger is Iran’s own public language. Watch for International Atomic Energy Agency board meetings, back-channel diplomacy turning into a signed communiqué, and any sanctions-for-stockpile exchange wording. Without a public Iranian pledge by the deadline, the settlement logic points firmly to No.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

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.
