Trump called a US-Iran ceasefire extension “highly unlikely,” pushing the Polymarket contract for an extension by April 21 down to 38.5% YES from 86% yesterday.
Market reaction
Traders sold the ceasefire extension contract hard. The April 21 sub-market, just 3 days out, dropped 22 points in a day. Odds for Trump announcing the ceasefire’s end by April 21 rose to 8.5% YES, up from 6% yesterday.
Order book data shows $9,463 in liquidity required to move the extension odds 5 points, a relatively thick book. The largest single move was a 4-point drop earlier in the session. The ceasefire-end announcement market is much thinner: only $880 needed to shift it 5 points.
Why it matters
Trump’s statement means military operations could resume if no deal materializes before the deadline. The end of military operations by April 30 contract trades at 35.5¢ YES, paying $1 if diplomacy produces a result within 12 days.
What to watch
Statements from Trump’s envoys or Pakistan’s mediators. Any signal of resumed negotiations could move these contracts fast.
