Four Iranian oil tankers have broken through the US blockade, according to Tasnim. The Polymarket contract for WTI Crude Oil hitting $160 in April sits at 1% YES.

Market reaction

Traders are watching the WTI Crude Oil April markets after the breach, which suggests a slight easing of supply constraints. The overall blockade remains effective, keeping upward pressure on oil prices. The April 30 contract holds at 1% YES, unchanged from a week ago.

Why it matters

The breach may point to some supply relief, but geopolitical tensions continue to support high oil prices. The April market trades at 0.7% YES, down from 1% 24 hours ago. Face value is $49,622/day, but actual USDC traded is only $514, with $1,955 needed to move the price 5 points. The market is thin and easily moved by large trades.

What to watch

The tanker breaches are a minor signal, not a game-changer. The ongoing blockade and geopolitical tensions still push oil prices higher. Buying YES at 1¢ could pay $1 if WTI hits $160, a 100x return. That bet only makes sense if you expect a major escalation or supply disruption well beyond current conditions.

Watch for further reports on tanker movements and any official statements from CENTCOM or Iran’s leadership. Either could shift the market’s pricing of supply disruption risk.
