California Drivers Sue Major Gas Retailers Over AI-Driven Price-Fixing Claims

Alleged AI-Powered Pricing Scheme
On June 22, 2026, a proposed class-action was filed in the U.S. District Court in Sacramento. California motorists allege that more than 1,700 gas stations operated by BP, Marathon Petroleum, Circle K, 7-Eleven, Walmart, Albertsons and others used Kalibrate’s AI-based fuel-pricing platform to coordinate pump prices, violating the state’s antitrust statutes.
Legal Context
The complaint cites violations of the Cartwright Act and Assembly Bill 325 (AB 325), a 2026 amendment that bans the use of shared pricing algorithms. AB 325 was enacted after the 2025 RealPage antitrust case, which targeted algorithmic rent-setting software.
Parties and Technology
Defendants include major retailers—BP, Marathon Petroleum, Circle K, 7-Eleven, Walmart, Albertsons—and the software firm Kalibrate, whose parent Knowledge Support Systems provides the Kalibrate Fuel Pricing system that aggregates cost and volume data to generate price recommendations.
Price Impact Data
The suit claims the AI tool can raise gasoline prices by as much as 30 cents per gallon in markets where it is widely used; other filings cite increases of 22 cents. Plaintiffs estimate each cent adds $134 million annually to California drivers’ expenses, with some stations reported at $7 per gallon.
Broader Significance
The case tests the enforceability of AB 325 and raises questions about the role of AI in competitive markets, potentially shaping future regulatory approaches to algorithmic pricing and consumer-protection enforcement nationwide.
Official Statements
Walmart said it is reviewing the complaint and will respond appropriately. BP declined to comment. Kalibrate did not immediately respond, but its website asserts that each retailer’s AI instance operates independently with no shared data.
Plaintiffs’ Critique and Defendant Defense
Plaintiffs argue the AI system enables a cartel that “wrings more money from the pockets of consumers” and produces “artificially high” pump prices. Defendants contend the software merely automates pricing decisions and that any price rise may reflect broader market factors such as oil costs.
Conflicting Reports & Gaps
Sources differ on the magnitude of alleged price hikes—some cite 22 cents, others up to 30 cents per gallon—and on the exact number of stations involved, ranging from “more than 1,700” to 1,732. The complaint does not address whether diesel prices were similarly affected.
