US obtains Iranian enriched uranium by 2026?

Market context

The market is pricing **0%** for the United States to formally say it has physically taken custody of Iranian enriched uranium by the deadline, and that is consistent with the base case: possession is far more demanding than a political promise or a disposal agreement. Reuters-linked reporting quoted Iranian officials as saying the stockpile should **not leave the country**, while U.S. officials have discussed disposal or dilution as a negotiating target rather than a completed handover.[4][3]

Historically, the relevant comparator is not a normal arms-control deal but a high-risk retrieval operation under military or coercive conditions. The BBC notes experts believe seizing the material would likely require ground forces, specialist handling teams and secure access to underground sites, while the New York Times reports the stockpile may be dispersed across Isfahan, Natanz, Fordo and possibly undisclosed locations, making actual custody difficult without Iranian cooperation.[2][1] That backdrop makes the market’s consensus bearish on a Yes, with the only obvious contrarian angle being an unexpected, verified transfer after a breakthrough agreement; even then, a later deal or surrender plan would not be enough unless the U.S. had possession by the settlement condition.[3][4]

For traders, the key catalysts are any official White House, Pentagon or IAEA statements that move from diplomacy to verified custody, plus reporting on inspection access, third-party transfer arrangements and the physical status of storage sites.[1][3][4] The main dependency is whether Iran allows removal at all: current reporting says Tehran has ordered the uranium kept inside the country, and talks on the “enriched material” have been described as deadlocked or postponed, which leaves the favourite firmly on **No** and any Yes value dependent on an improbable, explicit, and operationally confirmed transfer.[4][3]

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.
