Tensions in the Gulf are stoking fears of oil supply disruptions, with the Strait of Hormuz at the center of concern. Prediction markets now give crude oil a 15.5% chance of hitting a new all-time high by December 31, and an 8.8% probability by September 30.
The Strait of Hormuz chokepoint
The Strait of Hormuz is a narrow waterway between Iran and Oman. Roughly a fifth of the world's oil passes through it each day. Any closure — even a temporary one — would cut off a huge chunk of global supply. That's why the mere threat of disruption can move prices.
Recent military posturing and diplomatic breakdowns in the region have put the strait back in the spotlight. Traders are watching for any sign of escalation that could block tanker traffic.
Betting on a record
Prediction markets, where participants wager on real-world outcomes, show a growing belief that crude will break its previous peak. The odds have climbed from lower levels earlier this year. The 15.5% probability for a new all-time high by year-end is the highest so far in 2025.
The September 30 deadline — just a few months away — carries a lower chance at 8.8%. That suggests traders see the risk as more likely to materialize later in the year, if at all.
What the odds mean
These probabilities are not forecasts. They reflect the collective guess of people putting money on the line. Still, they offer a snapshot of market sentiment. A 15.5% chance is far from a sure thing, but it's high enough to keep oil buyers nervous.
If the strait stays open and tensions ease, those odds will drop. If a confrontation happens, they could spike quickly.
