Iranian-sanctioned supertanker crosses Strait of Hormuz despite US blockade

An Iranian-sanctioned supertanker passed through the Strait of Hormuz unchallenged by the US naval blockade. The market for UK warship transit by April 30 is at 8.5% YES, up from 4% a week ago.

The unimpeded passage points to gaps in blockade enforcement, and traders are reassessing the likelihood of UK and allied warships moving to ensure freedom of navigation. The market for UK warships through the Strait by April 30 doubled over the past week to 8.5% YES. The largest movement was a 3-point spike at 7:21 PM, driven by expectations of an increased naval presence.

The market for Trump’s blockade announcement by May 31 is at 83.5% YES, up from 79% yesterday. The supertanker’s passage raises questions about the blockade’s effectiveness and could delay any lifting announcement. Traders appear to be pricing in the need for more conclusive enforcement or a diplomatic resolution before that market moves further.

Trade volume is thin: $2,627 in USDC traded daily, with just $942 required to move the odds 5 points. The 3-point spike from a single order shows that even modest positions can shift prices meaningfully.

At 8.5¢, a YES share on UK warship transit pays 11.8x if it resolves YES. That’s a contrarian bet on allied naval action within 15 days, premised on the blockade’s current inability to stop even sanctioned tankers.

Watch for communications from UK defence, naval movements by allies, or US policy shifts on blockade enforcement. Any public confirmation of warship deployments or naval engagement near the Strait could move these markets fast.
