Iran seized two commercial ships in the Strait of Hormuz, and the market for Iran conducting military action by April 30 is locked at 100% YES.
Market reaction
The probability of another country conducting military action against Iran by April 30 dropped from 10% a day ago to 6% YES. Traders appear to be pricing in diplomatic responses over military retaliation. The market for another country striking Iran by April 15 is effectively dead at 0.1% YES.
Why it matters
The April 30 Iranian military action market has trading volume at $1,347 in actual USDC, with $1,303 required to move the odds by 5 points. That’s enough liquidity for small positions but leaves the market vulnerable to large trades. The ship seizures are a direct escalation in one of the world’s most strategically important shipping lanes, yet the counter-strike market moved down, not up.
What to watch
A YES share for military action against Iran by April 30 at 6¢ offers a potential 16.67x return, pricing in heavy skepticism of immediate retaliation. The current odds don’t offer much upside unless there’s a concrete shift in US posture. Watch for statements from the US Department of Defense, any new operational language from CENTCOM, and Trump’s response in the coming days.
