Iran agrees to end enrichment of uranium by July 31?

Platform comparison

Market context

If Iran publicly agrees to end all uranium enrichment by 31 July 2026, this market resolves **Yes**; a **No** share pays out if there is no such public pledge or agreement by then. In practice, traders are judging not just whether talks continue, but whether Tehran accepts a clear commitment to stop enrichment altogether, even if the arrangement is only political at first and not yet fully implemented.

The current price sits in the middle because the historical record cuts both ways. Iran accepted strict enrichment limits under the 2015 JCPOA, but later exceeded them after the deal unravelled; by 2024–25, watchdogs and arms-control groups said Iran had expanded enrichment to 60% and built up a much larger stockpile, sharply shortening breakout time.[2][3][5] That history makes a full public reversal plausible only if a wider diplomatic package is on the table. Reuters reported on 14 June 2026 that a draft US deal discussed nuclear limits and that Iran would maintain the current status of its programme, refraining from further uranium enrichment while talks continued.[7]

The main catalysts are any formal announcement from Tehran, a signed memorandum or framework with the US or intermediaries, and whether enrichment is explicitly covered rather than implied. Traders will also watch IAEA reporting and whether inspectors regain access, because verification language often signals whether a pledge is real or merely declaratory.[2][5][6] A recent media report suggested a US-Iran memorandum has been floated and that uranium disposition would be worked out over the next 60 days, which would matter only if Iran itself publicly accepts ending enrichment before the deadline.[1]

Methodology

We track Iran agrees to end enrichment of uranium by July 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
