Iran agrees to end enrichment of uranium by July 31?

Platform comparison

Market context

Iran publicly agreeing to end uranium enrichment by 31 July would mark a major reversal from the position Tehran has held since it began breaching JCPOA limits in 2019 and then announced in 2020 that it had abandoned all JCPOA enrichment constraints. Historical comparables matter because the 2015 nuclear deal did not end enrichment entirely; it capped levels, reduced stockpiles and tightened inspections, while Iran later restored higher enrichment after the U.S. withdrew in 2018. More recent background also cuts against a clean “Yes”: in 2025 the IAEA was still reporting a larger 60% enriched stockpile, and arms-control reporting said Iranian officials continued to treat retaining enrichment on Iranian soil as a red line.[1][4][5]

For traders, the key catalysts are formal Iranian statements, any U.S.-Iran mediation via Oman, and whether nuclear talks are linked to sanctions relief or inspection terms. The market wording is broad: any public pledge, unilateral or negotiated, to end all enrichment by the deadline should qualify, even if implementation is delayed. That means headlines from Tehran, the foreign ministry, or a joint communiqué could move the market quickly, as could an IAEA report or a deal framework that explicitly bars enrichment inside Iran. The regulatory angle also matters for access: a market like this sits within the wider prediction-market environment where German GlüStV rules can restrict local participation, U.S. CFTC jurisdiction can reach certain venues or users, and “no-KYC up to $1,500” generally means smaller accounts can open and trade with limited identity checks, but only within the platform’s stated thresholds and applicable geofencing. Recent reporting on the 2025 talks noted five rounds by June and continued disagreement over whether any settlement would allow enrichment inside Iran, which remains the central swing factor for this contract.[5]

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.
