Iran Nuclear Deal Odds Ease as Tehran Hardliners Block Enrichment Terms

April 25, 2026 · flowframe Pulse

Polymarket's US-Iran nuclear deal by April 30? contract dipped by 3.6% as traders reassessed the feasibility of a diplomatic breakthrough before the month-end deadline. The price action followed reports of mounting friction within the Iranian negotiating team and the White House's continued emphasis on "Operation Economic Fury." This shift reflects a growing consensus that a formal, signed agreement remains out of reach for the current administration.

The downturn was catalyzed by an April 25 report from the Institute for the Study of War indicating that Iranian hardliners, led by IRGC Brigadier General Ahmad Vahidi, have successfully sidelined pragmatists like Mohammad Bagher Ghalibaf. Vahidi’s camp is reportedly rejecting the "zero enrichment" demand set by President Donald Trump during recent talks in Islamabad. Furthermore, IAEA Director General Rafael Grossi warned on April 21 that any agreement lacking robust verification would be an "illusion," further dampening hopes for a near-term resolution.

Market participants reacted to these diplomatic headwinds by pushing the contract price from 10¢ down to 7¢ in recent trading. With a total volume of $2.3 million, the movement shows sustained interest from sellers despite the contract's low absolute value. The current pricing now implies a 7% probability that a deal will be finalized before the April 30 cutoff, a notable cooling from the more optimistic sentiment observed at the start of the week.

Investors are now monitoring the April 30 expiration of the current Pakistan-mediated ceasefire as the next major pivot point. Any statement from the Supreme Leader’s office or a formal U.S. State Department update regarding the proposed 20-year enrichment moratorium will likely drive further price volatility. Should the deadline pass without a signature, traders expect a swift return to the administration’s kinetic military posture.
