Prediction markets have sharply repriced crude oil risk following escalations in geopolitical tensions. Brent crude surpassed $100 a barrel for the first time in six weeks, trading at $101.09 on Wednesday morning, up 3.2 percent on the day, while West Texas Intermediate (WTI) settled at $96.27.
The trigger: Saudi officials reported Houthi rebels attacked Saudi oil facilities early Tuesday, injuring 73 individuals. Simultaneously, U.S. Central Command destroyed five Iranian oil tankers on Tuesday, following three additional destructions on Saturday in response to Iranian ballistic missile attacks targeting an American warship.
On Myriad, the prediction platform contract on whether crude will reach $120 or $55 first now prices $120 at 56.5 percent probability—a decisive 15.1-point swing. The $120 outcome overtook $55 at the start of September and has maintained its lead. Prior to this shift, $55 had led for most of the period since mid-August, with both sides trading within a few points of each other. The contract has accumulated $12.7 million in total volume since March.
Polymarket, which structures contracts with explicit deadlines, shows more immediate repricing. The probability of WTI touching $100 in September now stands at 59 percent, a nine-point increase. Expectations for WTI reaching $105 jumped 25 points to 30 percent. Conversely, the probability of WTI dropping to $85 in September fell 33 points to 39 percent. All price targets below $85 are now in single-digit probabilities, with the $55 target trading at just 1 percent.
The time-horizon difference between platforms explains the divergence. Polymarket's contracts expire at month-end; Myriad's market runs until one target is hit, without a specific deadline. This explains why Myriad still prices the eventual $55 outcome at 44.8 percent despite the sharp repricing toward $120.
Consumer fuel prices have begun to reflect these movements. Diesel recorded a new high of $5.94 a gallon on Wednesday, surpassing the previous record set the prior week. Gasoline prices averaged $4.22 a gallon across the U.S.
