Iran agrees to surrender enriched uranium stockpile by 2026?

Market context

Iran would need to publicly commit to transferring some or all of its enriched uranium stockpile by 31 March 2026 for this market to settle “Yes”. That is a much narrower and more explicit step than broad nuclear talks or temporary enrichment pauses. The 2015 JCPOA showed that Tehran can accept limits on enrichment and enhanced inspections when sanctions relief is concrete, but that deal was built around verified caps, not a public pledge to surrender stockpiles outright. Since the US left the JCPOA in 2018, Iran has expanded enrichment and reduced cooperation with inspectors, making any explicit surrender agreement materially harder than a routine diplomacy headline.

For traders, the key catalysts are whether Oman, European intermediaries, or the UN nuclear watchdog report a deal language change from “freeze” or “cap” to “transfer”, “ship out” or “surrender” of uranium. Recent reporting on Omani-mediated proposals and counteroffers has pointed to time-limited suspensions and stockpile-related formulas, but not a public Iranian commitment to hand over material. Watch for statements from the IAEA board, Iranian Foreign Ministry briefings, and any US or Israeli comments tied to prisoner swaps, sanctions relief, or inspection access, as these often move from vague contact to specific nuclear terms. With the crowd at 0% “Yes”, the market is effectively saying no public pledge is expected unless diplomacy shifts sharply and quickly.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
