US warns Iran of combat readiness as ceasefire market activity surges

US Defense Secretary Pete Hegseth warned Iran that US forces are prepared to restart combat operations if Iran doesn’t agree to a deal. The likelihood of a US declaration of war on Iran by December 31 is at 7.5% YES.

The diplomatic meeting market for June 30 sits at 2.3% YES, with traders skeptical about any diplomatic progress in the near term. The declaration of war market for December 31 dropped from 8% a week ago to 7.5% YES, meaning traders are not yet convinced of escalation to formal war.

The US-Iran ceasefire market shows more movement. Odds for a ceasefire ending by April 21 are at 7.5% YES, up amid concerns over renewed hostilities and ongoing proxy attacks. The odds for a ceasefire by April 30 climbed to 38.5% YES, up from 19% a week ago, meaning some traders still see a path to resolution even as Hegseth ratchets up rhetoric.

The ceasefire market is highly active, with combined 24-hour volume at $2,457,618 face value and $686,627 in actual USDC traded. The largest single move was an 8-point drop in the April 22 sub-market, showing rapid trader reactions to developments.

Hegseth’s statement signals that the current ceasefire is fragile and that the US is ready to escalate if diplomatic efforts stall. This adds direct pressure on Iran to negotiate or face intensified military action. For traders, the contrarian bet is in the ceasefire markets: buying YES at 7.5¢ pays $1 if the ceasefire ends by April 21, a 9.5x return, but requires belief in imminent breakdown within five days.

Watch for announcements from CENTCOM, changes in Iranian military posture, or new diplomatic engagements. Any of these could move the markets fast.
