CENTCOM confirmed the U.S. Navy’s blockade has forced 38 ships to turn around from Iranian ports. The Polymarket contract on Strait of Hormuz traffic returning to normal by May 15 sits at 14.5%, down from 20% yesterday.
Market reaction
May 15 normalization odds dropped 5.5 points in 24 hours to 14.5%. The market has a 21-day horizon, and the largest recent move was a 2-point spike yesterday. Liquidity is moderate: $36,459 in actual USDC traded over the last 24 hours. The cost to move odds 5 points is $4,658, meaning the order books are thin enough that a single large trade could shift sentiment fast.
Why it matters
The steady decline from 20% to 14.5% in one day shows traders pricing in a longer blockade. With 38 ships already turned back and no public diplomatic track, the market is betting against a quick resolution. At 14.5¢, a YES share pays $1 if traffic normalizes by May 15, a 6.9x return. That payout only makes sense if you expect a diplomatic breakthrough or sudden de-escalation within three weeks.
What to watch
Official CENTCOM statements on blockade scope, any back-channel or public peace talks, and changes in naval deployments in the strait. Any of these could move the May 15 contract sharply in either direction.
