Drivers Sue Big Chains Over AI-Driven Gas Prices
23 Jun
Summary
- California drivers filed a class action lawsuit accusing BP, Walmart, and others.
- AI software platform Kalibrate is accused of coordinating gas prices.
- A new California law makes algorithmic price fixing illegal since January 1.

A class action lawsuit was filed on Monday in Sacramento, California, alleging that several major gas station chains and a software company used artificial intelligence to coordinate high prices. Defendants include BP, 7-Eleven, Walmart, and Albertsons, alongside software platform Kalibrate.
The lawsuit claims these entities colluded to set gas prices, thereby artificially inflating costs for consumers. This legal action is particularly significant in California due to a recent amendment to the state's antitrust law.
Effective January 1, 2026, this amendment specifically outlaws the use of common pricing algorithms that leverage competitor data to influence prices. The law defines such algorithms broadly, encompassing any technology used by multiple parties to set or stabilize prices.
Plaintiffs in the suit are identified as California drivers. Representatives from the accused companies have not yet responded to requests for comment.
