Iran agrees to end enrichment of uranium by June 30?

Platform comparison

Market context

Iran publicly agreeing to end all uranium enrichment by June 30, 2026, remains a near-impossible outcome, reflected by the contract’s current 0% YES price on Polymarket. Traders viewing this on-chain USDC/Polygon market understand that conditional tokens here are pricing the sheer lack of any credible diplomatic pathway for Tehran to surrender its nuclear programme unilaterally or via agreement.

Historical precedents frame this probability starkly: the 2015 JCPOA, which capped enrichment at 3.67% and reduced stockpiles, expired in October 2025, after which Iran immediately resumed higher-level enrichment and expanded its stockpile to over 400 kg of 60% pure uranium[3][4]. Unlike the JCPOA’s temporary constraints, current US proposals advocate for a regional consortium model prohibiting enrichment on Iranian soil entirely, a demand Tehran has consistently rejected as a central sticking point in five rounds of talks mediated by Oman[4]. The market’s zero probability aligns with Iran’s refusal to accept such fundamental limits, even as Trump officials claim they compelled a permanent restriction to 3.67% in a recent MOU that focuses on dismantling blockades rather than ending enrichment[2].

Traders must monitor the draft US deal’s finalisation, specifically whether it includes an oil sanctions waiver and nuclear limits that Tehran might accept[7]. Key catalysts include the next round of negotiations, any IAEA reports confirming stockpile changes, and whether the US moves from proposing a regional consortium to demanding immediate on-site dilution[4]. A recent Reuters report notes Iran’s draft deal includes an oil sanctions waiver, yet the core dispute over enrichment remains unresolved[7]. Without a public pledge from Iran to halt enrichment entirely, the contract will resolve to No.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
