Iran’s Revolutionary Guard seized two vessels in the Strait of Hormuz, and the Polymarket contract on the UK sending warships through the Strait by April 30 now sits at 2% YES, down from 6% a day ago.
Market reaction
The UK warship deployment contract trades at 2% YES, unchanged across multiple sub-markets for the April 30 deadline. The drop from 6% happened over the past 24 hours. Term structure is flat, and sub-markets for Canada, India, Pakistan, and France show no movement either, meaning traders aren’t pricing in a response from any of these countries.
Why it matters
Combined trading volume across these markets is $52,688 in face value over the last 24 hours, but actual USDC traded is only $1,142. That makes these contracts thin: just $343 can move the odds by 5 percentage points. A single moderately sized order could create large swings in the displayed probability.
What to watch
A YES share at 2¢ pays $1 if the UK sends warships through Hormuz by April 30, a 50x return. That bet only makes sense if you believe a UK naval response is likely within seven days. The key trigger would be a statement from the UK Ministry of Defence or allied navies confirming warship movements toward the Strait. Without that, the 2% price reflects traders’ view that diplomatic channels, not naval deployments, are the more likely near-term response.
