Iran is preparing for potential conflict as the ceasefire with the US approaches its expiration. The market for a ceasefire termination by April 21 has dropped to 4% YES, down from 36% a week ago.
## Market reaction
The market for Trump announcing the end of the ceasefire has collapsed, with traders pricing in very low odds of an imminent announcement. Iran’s reported military repositioning and updated target lists signal readiness for immediate strikes, which could move the odds quickly if confirmed. At 4%, the short-term market says traders expect no escalation within the next day.
The US declaration of war on Iran by April 30 sits at 1% YES. Even with Iran’s preparations, traders see a formal war declaration as near-impossible this month. The longer-term market extending to December 31 is at 6% YES, indicating traders assign a higher chance of escalation later in the year.
## Why it matters
The ceasefire end market saw its largest recent single move with a 7-point spike, driven by $21,601 in USDC traded over the past 24 hours. The order book is thin: only $465 is needed to shift the price by 5 points, meaning a single large order could move the market substantially.
## What to watch
For traders, buying YES for a ceasefire end by April 21 at 4¢ pays $1 if announced, a 25x return. That bet requires a last-minute breakdown or a surprise announcement from Trump.
Watch for statements from the Pentagon or Trump’s official channels. Any confirmation of Iranian military actions or a shift in US diplomatic posture could move the odds fast.
