Iranian state TV reports the ceasefire will expire at midnight GMT, April 22. The probability of a US-Iran ceasefire extending beyond April 30 is at 30.5% YES, down from 36% a week ago.

The market for Trump announcing the end of military operations against Iran by April 30 is reacting to the expiration announcement. April 30 odds have dropped, with the largest move being a 4-point drop at 4:28 PM. Ten days remain until the April 30 deadline, and traders are pricing in resumed military actions.

Diplomatic meetings are also looking less likely overall, though short-term movement is mixed. The probability of Trump meeting with Iran by April 30 is at 9.1% YES, up from 16% twenty-four hours ago but still low. The rise suggests some traders see a narrow path to diplomacy even with the ceasefire expiring. Vice President JD Vance’s trip to Pakistan is on hold, which further complicates the diplomatic picture.

The US-Iran ceasefire market sees $54,670 in actual USDC traded daily, with just $841 needed to move the odds 5 points, making it a thin market where small trades can have outsized effects. The diplomatic meeting market trades $10,425 in actual USDC daily, with $2,188 needed to shift odds by 5 points. The largest spike in that market was a 4-point jump, likely driven by speculative bets on a surprise diplomatic opening.

The ceasefire expiration points toward escalation. Traders are pricing in a breakdown in negotiations. Buying YES at 30.5¢ offers a 3.28x return if military operations formally cease by April 30. That bet requires believing talks will revive or an unexpected diplomatic development will occur within 10 days.

Watch for resumed talks or new military actions. Trump, Rubio, and intermediaries from Oman and Qatar are the key figures. Statements from the White House or Iranian state media could move market odds quickly.
