A high-stakes prediction market on Polymarket, "US obtains Iranian enriched uranium by May 31?", is currently trading with a strong lean towards a 'No' resolution, pricing the likelihood of a 'Yes' outcome at a mere 7.5%. The market, with a significant trading volume of nearly $9.5 million, hinges on whether the US government or military officially announces or confirms physical custody of any quantity of Iranian enriched uranium by the end of May 2026. This excludes mere announcements of deals or plans for future acquisition.

This market's significance stems from Iran's accumulating stockpile of highly enriched uranium (HEU), which international observers, including Washington, view as a serious proliferation risk. Iran is estimated to possess approximately 408 to 450 kilograms (900-1000 pounds) of HEU, a quantity that could be further enriched for several nuclear weapons. The International Atomic Energy Agency (IAEA) has expressed concerns, stating it has lost continuity of knowledge regarding Iran's nuclear materials and is unable to verify the stockpile, highlighting the absence of credible civilian justification for such enrichment.

Recent developments reveal a dual approach by the United States: intense diplomatic efforts alongside contingency military planning. Reports from early May 2026 suggest the US and Iran are nearing a one-page memorandum to end their ongoing conflict, which could include Iran agreeing to transfer its enriched uranium stockpile. US President Donald Trump has made assertive statements, declaring, "We're going to get it," and clarifying, "Not perhaps. It goes to the United States," indicating a firm US demand for the material.

However, Iran's public stance remains contradictory. While discussions about a potential transfer are reportedly part of broader negotiations for sanctions relief, Iran's foreign ministry has publicly rejected the idea of transferring uranium. An Iranian parliamentary spokesperson also reportedly stated that the US would not achieve through war what it failed to achieve through direct negotiations. Furthermore, Iran has reportedly offered to discuss nuclear issues, including transferring or diluting its HEU, in a later, second phase of a proposed three-phase plan to end the conflict.

The military option, a potential seizure of the uranium, has also been on the table. The Pentagon is reportedly planning a "short, sharp campaign" or a "smash and grab raid" for Iran's enriched uranium. President Trump was briefed on a complex plan involving ground forces and excavation equipment to seize nearly 1,000 pounds of HEU. Experts, such as former Deputy Assistant Secretary of Defense Mick Mulroy, have characterized such an undertaking as "one of, if not the largest, most complicated special operations in history," highlighting the significant risks involved. A major challenge to any seizure operation is the believed location of much of Iran's uranium stockpile under the rubble of facilities previously targeted by US strikes, making access difficult.

The current market odds reflect the immense difficulty in achieving physical possession by May 31. The tight deadline, coupled with Iran's resistance to a unilateral surrender and the inherent dangers and complexities of a military seizure, makes a 'Yes' resolution highly improbable in the immediate term. For comparison, other Polymarket windows for the US obtaining Iranian enriched uranium by December 31, 2026, show a higher probability, ranging from 24% to 28%, suggesting traders see a longer timeframe as more plausible for such an event to occur. The market's current pricing underscores the prevailing skepticism that the US will overcome these substantial hurdles within the next three weeks.
