Iran agrees to end enrichment of uranium by December 31?

Platform comparison

Market context

Iran would have to publicly agree to stop all uranium enrichment by 31 December 2026, and the market is effectively pricing the chance of a formal nuclear concession rather than a technical pause. The threshold is broad enough that any unilateral Iranian pledge, or a promise inside a deal with the United States or Israel, would settle **Yes** even if implementation is delayed, which keeps headline risk high whenever diplomacy moves. The current 64% implied probability sits against a backdrop of Iran having continued enrichment well beyond JCPOA limits, with recent arms-control reporting saying it has accumulated large stocks of 60% material and that enrichment remains the central sticking point in talks.[1][5]

Historically, similar markets have moved on small shifts in negotiating posture rather than on final text, because Iran has repeatedly used enrichment as both leverage and red line. The JCPOA once capped enrichment at 3.67%, but after the U.S. withdrawal Iran stepped above those limits and later expanded higher-purity production; by late 2024 the breakout timeline had shortened materially, which makes any genuine promise to end enrichment a major policy reversal.[3][5] That is why the price is sensitive to whether Tehran sticks to the familiar “status quo” language seen in Reuters-reported interim statements, which explicitly fell short of accepting full cessation.[2]

The main catalysts are diplomatic: a new Oman-mediated round, an IAEA board statement, a U.S. proposal that links civilian fuel supply to a regional consortium, or any Iranian public comments that shift from refusal to conditional acceptance.[1] Traders also need to watch payment-side frictions, because deeper book depth usually follows fresh deposits through low-cost rails; for a UK-facing venue, Klarna and SEPA reduce on-ramp friction, while USDC can bring faster cross-border funding when news breaks, which can widen spreads and accelerate repricing around overnight headlines. On a market like this, the timing of funding flows often matters as much as the diplomacy itself.

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 Polymarket Klarna UK, which mirrors the Polymarket order book directly.

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.
