Market context
The question hinges on whether the United States physically acquires enriched uranium that Iran previously controlled before 31 May 2026. This differs materially from diplomatic agreements or pledges to acquire such material later. The resolution criteria demand actual custody or control—whether stored in US territory or held elsewhere under US authority—with official government or military announcement as proof. Current market pricing at 0% reflects the absence of any active acquisition pathway or public negotiation framework as of late 2024.
Historical precedent suggests such transfers occur through either military seizure or negotiated nuclear agreements. The 2015 Joint Comprehensive Plan of Action (JCPOA) involved Iran shipping enriched uranium abroad but did not result in US possession; the Trump administration's 2018 withdrawal from the deal created no mechanism for uranium transfer. Military confiscation would require either direct Iranian territory access or interception of shipments—scenarios with no current indicators. The 18-month timeframe to resolution is compressed relative to typical nuclear diplomacy cycles, which often span years of negotiation.
Traders monitoring this market should track announcements from the State Department, Department of Energy, and IAEA regarding Iran's nuclear programme and any bilateral negotiations. Recent reporting from Reuters and AP News shows no active talks on uranium transfers as of Q4 2024. Key dependencies include shifts in US-Iran relations, potential military escalation in the Middle East, or unexpected diplomatic breakthroughs. For algorithmic monitoring, set alerts on official government press releases and IAEA statements; the binary nature of the resolution (physical possession confirmed or not) means intermediate signals like "talks progressing" carry limited predictive weight.
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
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
