Prediction markets grow more skeptical of a near-term agreement, with Kalshi assigning just 22% odds before 2028 and 35% before a later January deadline.
Prediction markets are turning increasingly skeptical about a near-term U.S.-Iran nuclear agreement. On Kalshi, the implied chance of a deal stands at 11% before March 1, 2027, 22% before January 1, 2028, and 35% before January 20. The sliding odds reflect diminished expectations that Washington and Tehran will reach a nuclear accord in the near term.
