The US-Israel conflict with Iran has disrupted the Strait of Hormuz, pushing fuel prices higher. The Polymarket contract on WTI Crude Oil hitting $160 in April sits at 1.4% YES, barely moving from 1% yesterday.

Market reaction

The WTI Crude Oil market remains skeptical at 1.4% YES. Traders are not pricing in a run to $160 within the month. The largest move was a 25-point spike yesterday evening, which quickly settled back down.

The market for Trump agreeing to Iranian oil sanction relief in April moved in the opposite direction. Odds fell to 43.5% YES, down from 62% yesterday. Traders are pricing in continued tension and a hardline stance on sanctions.

Why it matters

The WTI $160 contract is a thin market: $704 in actual USDC traded against a face value of $72,164. It takes $1,655 to swing the market by 5 points, meaning even small trades cause visible moves. The sanction relief market has more volume with $6,018 in USDC traded, but it only requires $816 to move 5 points.

The Strait of Hormuz closure is a real disruption, but the WTI odds say traders aren’t expecting a dramatic oil price spike. The drop in sanction relief odds, though, points to a hardening US stance that could prolong the conflict and keep upward pressure on prices.

What to watch

Official statements from the White House or any sign of diplomatic engagement. A breakthrough could shift these markets fast, especially if it involves reopening the Strait or easing sanctions.
