Trump’s decision to pull back from the Iran conflict suggests a shift towards diplomacy. The odds of a formal US war declaration on Iran by April 30 now sit at 0.7% YES.
Market reaction
The de-escalation has moved the US Declaration of War on Iran market, where odds for a declaration by December 31, 2026, are at 7.5% YES, down from 8% a week ago. The April 30 market sits at 0.7% YES with only 14 days left. The market is thin: $327 in daily USDC volume, meaning it would take $2,378 to move the odds by 5 points.
Meanwhile, the US-Iran Peace Deal market has shifted toward optimism. The likelihood of a peace deal by April 22 is at 30.5% YES, up from 12% a week ago. May 31 odds rose from 31% to 61.5% YES. The biggest jump falls between April 30 and May 31, suggesting traders expect a specific diplomatic catalyst during that window.
Why it matters
Volume at $698,114 in actual USDC traded in the peace deal market reflects real trader interest, with liquidity deep enough to absorb $19,067 without moving the odds more than 5 points.
Trump’s withdrawal from Iran, based on faulty intelligence and unsustainable costs, is a clear break from the sunk cost fallacy. For traders, YES shares on a peace deal by May 31 at 61.5¢ imply a 1.79x return if successful. That bet assumes diplomatic talks progress quickly over the next 45 days.
What to watch
Secretary of War Pete Hegseth’s briefings and any new statements from the Iranian Foreign Ministry. These could clarify the US’s next steps and either confirm or challenge current market pricing.
