Summary

A California lawsuit alleged Walmart, Albertsons, and other retailers used Kalibrate’s pricing software to raise fuel prices.

Why this matters

The case could affect how fuel retailers use pricing software and whether drivers in California may recover damages for alleged overcharges. It also tests a 2025 California law barring shared pricing algorithms.

A class-action lawsuit filed in California alleged that Walmart, Albertsons, and other fuel retailers used an artificial intelligence pricing system to raise gasoline and diesel prices.

The suit said one cause of high fuel costs in California was retailers’ use of pricing software from Kalibrate, which allegedly connected directly to gas stations and used competitors’ data in a way that fixed prices rather than encouraging stations to lower them.

“While families struggle to afford the commute to work, Defendants have conspired to put an end to competition, joining an AI-powered trust to ensure that no matter where a driver turns, the price for gasoline is artificially high,” the court document states.

According to the lawsuit, the retailers’ use of Kalibrate violated California antitrust law and AB 325, a state law passed in 2025 that prohibits shared pricing algorithms. The suit said the companies “have replaced independent, competitive pricing with a coordinated, automated mechanism that relies on sensitive competitor data and a conscious decision to ensure that prices remain artificially high,” which it said was barred under the law.

The lawsuit sought a jury trial and damages for California drivers who, it said, overpaid for fuel at more than 1,700 gas stations in the state. It alleged that station owners raised gasoline prices by as much as 22 cents a gallon and diesel prices by as much as 33 cents a gallon, costing drivers $134 million a year.

Gas prices have also been affected by broader market forces. Trading Economics said gasoline prices were about $2.99 a gallon on average nationwide, down from $3.74 a few months earlier but above 2025 levels of just over $2 a gallon. Forbes reported that prices in some West Coast states, including California, Washington, and Hawaii, exceeded $5 a gallon.
