IRGC attacks commercial ships in Strait of Hormuz, UK warship deployment uncertain

US defense officials reported at least three IRGC attacks on commercial ships in the Strait of Hormuz since Saturday morning. The market for the UK sending warships by April 30 sits at 6% YES.

## Market reaction

The UK warships in the Strait of Hormuz market hasn’t moved, unchanged from a week ago despite the new attacks. The April 30 deadline is 14 days away, and with no new orders from the UK Ministry of Defence, traders are pricing in inaction.

Face value on this market is $24,906 per day but only $2,086 in actual USDC. It takes just $427 to shift odds by 5 percentage points, making this a thin market where a single trade could move the price significantly. The largest move was a 1-point drop at 8:42 AM.

## Why it matters

Previous attacks have targeted Indian-flagged vessels and tankers under gunboat fire, but no country covered by Polymarket’s contracts (UK, Canada, India, Pakistan, or France) has signaled a deployment. The gap between real-world escalation and market pricing reflects the absence of concrete political or military commitments. Buying YES at 6¢ offers a 16.67x return if a deployment occurs, but that would require a rapid policy shift with less than two weeks remaining.

## What to watch

Official announcements from the UK Ministry of Defence or allied navies, any IRGC provocations against allied-flagged vessels specifically, and diplomatic moves that could change the calculus on naval deployment before the April 30 deadline.
