Iran and US blockades of Hormuz fail to spike oil price expectations

Mutual blockades of the Strait of Hormuz by Iran and the US have rattled oil markets, but Polymarket traders remain deeply skeptical of a price spike. Crude oil reaching an all-time high by April 30 sits at 0.8% YES, down from 2% earlier this week.

Market reaction

The odds for WTI crude hitting $160 in April are even lower at 0.2% YES. Both sides are enforcing strict naval controls in a region responsible for around 25% of global seaborne oil trade, yet traders are pricing in almost no chance of a record-breaking price move.

Trading volume reflects that skepticism. The crude oil all-time high market saw just $2,513 in USDC traded, with a thin order book where $695 can move the price 5 percentage points. Liquidity is low — traders appear to be waiting for more definitive actions from OPEC+ or a shift in US-Iran diplomacy before committing capital.

Why it matters

The dual blockade constrains a major oil transit chokepoint, but the market response says traders don’t expect an immediate breakdown in supply. At 0.8% YES, a share pays $1 if crude oil exceeds $120/barrel by April 30, a 125x return. For that bet to pay off, traders would need to see a complete collapse of diplomacy or new aggressive actions in the Gulf within the next six days.

What to watch

Any production adjustments from OPEC+ members or revised energy market forecasts from institutions like the EIA or Goldman Sachs could shift these odds quickly. The timeline is tight: April 30 is less than a week away, and the current pricing implies traders expect some form of de-escalation or at least stable supply flows.
