Kalshi traders are not expecting a U.S. and Iran nuclear deal soon

• Odds of a nuclear deal before January 2027 rose from 17% Saturday evening to 29% early Sunday after Trump called off strikes at the request of Saudi Arabia, UAE, Qatar and Iran
• All Kalshi market timeframes show under 50% probability of a deal except for the January 2029 horizon, the furthest date available
• Oil prices fell significantly on the news, with September crude futures dropping 6% below $80 per barrel and October Brent futures declining over 4%

Summary: U.S.-Iran Nuclear Deal Expectations Remain Low on Kalshi

Key Developments

Kalshi prediction markets show traders are pessimistic about near-term prospects for a U.S.-Iran nuclear deal, despite diplomatic developments. As of early Sunday morning, traders assigned only a 29% probability to a deal before January 2027, up from 17% Saturday evening. The likelihood of an agreement before March 2027 rose to 40% from 20%.

Geopolitical Context

The modest uptick in odds followed President Trump's decision to cancel planned military strikes against Iran late Saturday night, influenced by requests from Saudi Arabia, UAE, Qatar, and Iran. Trump subsequently announced negotiation talks scheduled for Monday, though Iran's Foreign Ministry spokesman Esmail Baghaei denied any immediate plans for discussions.

Market Sentiment

All Kalshi markets pricing deal timing show probabilities under 50%, except for the longest-dated market extending to January 2029. Markets would settle positively if the U.S. agrees to, signs, or accepts a nuclear deal with Iran, according to Kalshi's verification criteria.

Market Impact

Oil markets reacted to the diplomatic news and strike cancellation. September WTI crude futures dropped 6% to below $80 per barrel, while October Brent futures fell more than 4%.

Bottom Line

Despite diplomatic engagement announcements, prediction market traders remain skeptical about imminent breakthrough between Washington and Tehran, with only the longest time horizons showing above 50% probability of success. The muted expectations persist even as tensions eased following canceled military action.
