Market context
Polymarket’s contract implies a **47%** chance that Iran will publicly agree to end all uranium enrichment by the deadline, with the position representing a claim to USDC-settled conditional tokens on Polygon rather than a view on whether the policy would ever be implemented. Because the market resolves on a public pledge, not proof of centrifuge shutdowns, a trader should focus on statements from Tehran, U.S.-Iran diplomacy, and any agreement language that explicitly covers *all* enrichment, even if only for a limited period.[8]
The current price sits in the shadow of the JCPOA’s collapse and its sunset mechanics. Iran originally accepted enrichment limits under the 2015 deal, but after the U.S. withdrew in 2018, Tehran progressively breached those caps and later moved to much higher enrichment levels; IAEA and arms-control sources now describe a substantial stockpile of 60% material and continued use of advanced centrifuges.[2][4][7] That history matters because a full reversal would be a sharp break from Iran’s recent negotiating stance, and the market is pricing the chance of a formal public commitment, not merely a temporary pause or inspection-related concession.[6][8]
For traders, the key catalysts are diplomatic announcements, not technical facilities data. Watch for any U.S.-Iran channel via Oman, any European mediation, and any statement tied to a broader sanctions or security package, because the market allows a “Yes” on a unilateral Iranian pledge or one embedded in an agreement with the U.S. or Israel.[4][8] Recent IAEA reporting still shows Iran above civilian enrichment thresholds and holding a large 60% stockpile, which means a genuine “end enrichment” announcement would likely need to accompany a major political deal, not routine nuclear talks.[7]
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi UK, which mirrors the Polymarket order book directly.
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.
