Iran's Foreign Minister announced that the transfer of enriched uranium is not on the agenda, citing a lack of trust in the United States. The statement escalates tensions over Iran’s nuclear program, which have risen since the U.S. withdrawal from the JCPOA in 2018. Iran has since expanded enrichment beyond deal limits, and diplomatic efforts remain stalled.

The refusal is a major setback to U.S. demands, keeping the dispute at high escalation. Prediction markets now show a 5.5% probability of the U.S. obtaining Iranian enriched uranium by May 31, down from 6%. The chance of Iran surrendering its stockpile by end of 2026 fell to 43.5% from 44%.
