Iran’s closure of the Strait of Hormuz has pushed the probability of WTI Crude Oil hitting $160 in April to 1.4% on Polymarket, down from 3% a week ago, suggesting the market is skeptical about sustained disruptions.
Market reaction
The WTI Crude Oil $160 April contract saw a 25-point spike at 8:02 PM as traders reacted to the closure, but the price settled back to 1.4%. It takes $1,655 to move the market 5 points, and daily face value sits at $72,164, so there’s decent liquidity but the contract is still thin enough that a single large order could jolt it.
In the Strait of Hormuz Traffic Normalization market, odds of traffic returning to normal by end of April are falling. Iran is demanding tolls and threatening ships, and the US has acknowledged that negotiations are stalled.
Why it matters
The Hormuz closure affects roughly 20% of global oil transit. If the blockade persists and oil prices spike, secondary effects could appear in other prediction markets, including contracts on ECB rate decisions. A 50+ bps emergency cut would become more plausible if eurozone economies face energy-driven strain, though those odds remain low without concrete inflation data shifts.
What to watch
Buying YES at 1.4¢ for a 71.4x return on WTI’s April $160 target is a long-shot bet that depends entirely on further escalation. The next catalysts are statements from President Trump and the IRGC. Any shift in rhetoric, whether toward military action or a negotiated reopening, would move these contracts fast.
