Polymarket Predicts 'No' on US Obtaining Iranian Uranium by May 31 Amid Stalled Nuclear Talks

A Polymarket prediction market shows overwhelming odds against the United States gaining physical possession of Iranian enriched uranium by the May 31, 2026 deadline, reflecting the stalled nature of US-Iran nuclear negotiations and Iran's firm stance on its nuclear program.

The prediction market on Polymarket, "US obtains Iranian enriched uranium by May 31?", is currently heavily skewed towards a 'No' resolution, with prices at $0.0185 for 'Yes' and $0.9815 for 'No'. This indicates a strong consensus among traders that the United States will not gain physical custody or control of any quantity of enriched uranium previously controlled by Iran by the May 31, 2026, 11:59 PM ET deadline. The market's high trading volume of over $18 million underscores the significant interest in this critical geopolitical issue.

This market matters deeply for international security, reflecting ongoing concerns about nuclear proliferation and the volatile relationship between the US and Iran. Iran's stockpile of highly enriched uranium, particularly its 60% enriched material, is a significant point of contention, as it is considered a short technical step from weapons-grade purity. As of September 2025, the International Atomic Energy Agency (IAEA) reported Iran possessed 440.9 kg of uranium enriched up to 60% purity. However, the IAEA has stated it cannot assure Iran's nuclear program is exclusively peaceful and has lost "continuity of knowledge" over previously declared nuclear material since US and Israeli strikes in June 2025. Much of this stockpile may even be buried under rubble from those attacks.

Recent developments in US-Iran negotiations, mediated by Qatar, highlight the deep disagreements preventing a swift resolution. While talks are ongoing, they are reportedly stalled, with the US pushing for firm, upfront commitments on Iran's nuclear program, including the removal or destruction of its enriched uranium stockpile. President Donald Trump has explicitly stated he would not sign an agreement without the dismantling of Iran's nuclear program and the removal of all enriched uranium from Iranian territory. He has also suggested the uranium could be destroyed in place or at another acceptable location under international supervision.

Conversely, Iran's focus remains on securing relief from US sanctions and gaining access to frozen assets. Iranian officials maintain that the nuclear program and uranium stockpile should only be addressed in later stages of a broader agreement, after initial financial concessions are made. Iran has historically been unwilling to transfer its enriched uranium stockpile to either the US or Russia.

One recent development suggests Iran is considering shipping its 60% enriched uranium stockpile to China, with Beijing reportedly open to acting as a custodian. However, the specifics and safeguards required by the US remain unclear, and Iranian Supreme Leader directives reportedly prohibit such exports. Critically, this would not constitute direct US possession.

Market analysis aligns with the low probability of a 'Yes' outcome. Reports indicate that any potential agreement nearing by May 31, 2026, is likely a preliminary Memorandum of Understanding (MOU) focused on a 60-day ceasefire, reopening the Strait of Hormuz, and sanctions relief, deferring substantive nuclear negotiations, including the fate of the enriched uranium, to a later period. As one market commentator, 'Trader Claude,' noted on May 24, 2026, "A ceasefire is not a nuclear deal. Polymarket agrees: YES sits at just 21¢ with seven days to resolution.". The market's resolution criteria are strict, requiring actual physical custody or control by the US, not just an agreement for future acquisition.

Given the tight deadline and the fundamental disagreements persisting between Washington and Tehran, particularly Iran's insistence on addressing nuclear issues only after sanctions relief, the current market odds strongly reflect the unlikelihood of the US obtaining physical possession of Iranian enriched uranium by May 31.
