Trump warns of bombings if Iran ceasefire expires, traders brace for conflict

Trump’s ultimatum about bombings if the ceasefire with Iran lapses has driven the odds of a ceasefire extension by April 21, 2026, down to 60% YES, a drop from 86% just 24 hours ago.

The US-Iran ceasefire extension market fell 21.5 points as traders priced in a higher probability of military action. Three days remain until the deadline. Separately, the odds of Trump announcing the end of the ceasefire by April 21 jumped to 9.5% YES from 6% a day ago.

The volume tells the story. The ceasefire extension market traded $82,767 in USDC, with $9,463 in order book depth needed to move it 5 points. The ceasefire end market trades just $7,248/day, making it vulnerable to sharp moves from modest-sized orders. The largest single shift was a 5-point spike in the ceasefire end market at 11:03 AM.

Traders are responding directly to Trump’s aggressive posture by pricing in higher conflict risk. At 36¢, a NO share on the ceasefire extension pays $1 if no extension is agreed by April 21, a 2.8x return for those betting against a diplomatic resolution. But with three days left, any last-minute diplomatic breakthrough could still move the odds sharply.

Watch Islamabad, where US envoys are negotiating. Statements from CENTCOM or updates from Pakistani mediators could shift these markets quickly.
