Class Action Lawsuit Filed Against Major Gas Stations for Using AI to Inflate California Fuel Prices
A federal class action lawsuit filed this week accuses more than 1,700 California gas stations of using an AI-powered pricing platform to illegally collude and drive up fuel prices — raising costs for drivers by as much as 30 cents per gallon.
The proposed class action, filed Monday in the U.S. District Court for the Eastern District of California, names Kalibrate — a Manchester, England-based fuel-pricing software company operating in more than 70 countries — as the central orchestrator of what plaintiffs describe as a modern-day price-fixing cartel. Named corporate defendants include Marathon Petroleum, 7-Eleven, Walmart, Circle K, BP, Albertsons, and other major fuel retailers.
The plaintiffs describe Kalibrate’s software as the “central nervous system for a conspiracy to extinguish retail price competition among gas stations.” The system, known as Kalibrate Fuel Pricing, connects directly to gas station signs and pumps and uses competitor data to automatically set retail prices — allegedly nudging operators away from undercutting rivals and toward higher, coordinated price points.
According to the complaint, gas stations using Kalibrate software charge between 6 cents and 30 cents more per gallon than those operating under normal competitive conditions. The lawsuit also highlights a “restoration” tool within the platform that allegedly helps stations in a given area raise prices simultaneously and by significant amounts.
The lawsuit seeks to represent all California drivers who purchased fuel at Kalibrate-using stations since June 2022. Three named plaintiffs — Joel Casciani of Chula Vista, Paola Hartman of Homeland, and Crystal Turnbough of Marysville — claim they paid artificially inflated prices. The complaint does not specify a fixed damages amount but seeks actual losses plus treble (triple) damages.
California’s New Antitrust Law Is Central to the Case
The lawsuit rests heavily on AB 325, a California antitrust amendment that took effect on January 1, 2026, specifically targeting algorithmic price cartels. The law provides a legal basis for plaintiffs to argue that competing businesses using a shared pricing algorithm constitute an unlawful trade restraint under the Cartwright Act, California’s primary antitrust statute.
The California Energy Commission’s Petroleum Market Monitoring Unit has already issued a formal notice to fuel refiners, distributors, and retailers regarding their obligations under AB 325. A spokesperson confirmed that the unit “will continue to work to ensure that market participants fully understand their legal obligations in California.”
AI Pricing in Focus as California Fuel Costs Climb
The lawsuit arrives as California drivers face some of the highest gasoline prices in the nation, with averages in recent months hovering around $6 to $7 per gallon. Even small per-gallon increases carry outsized statewide consequences — according to the complaint, a single cent increase at the pump drains approximately $134 million from California drivers’ wallets annually.
The California Energy Commission had previously warned that branded gasoline could become significantly more expensive than unbranded fuel amid rising global oil prices linked to geopolitical tensions.
Kalibrate recently released a mobile app allowing fuel retailers to adjust station prices via smartphone, touting features including “AI-driven features designed to increase transparency in pricing.” The company did not respond to requests for comment.
A Broader Debate Over Algorithmic and Personalized Pricing
The lawsuit reflects growing regulatory and public scrutiny of AI-driven pricing across the economy. Dynamic pricing — adjusting prices based on demand, competition, and market conditions — has existed for decades across industries from airlines to ride-hailing. But critics argue AI now enables far more sophisticated forms of price coordination, including so-called supervised pricing, where retailers use personal consumer data to predict individual willingness to pay.
New York State enacted legislation in December 2025 restricting supervised pricing practices. California lawmakers are considering similar measures through Bill AB 2564, which would ban retailers from setting prices based on personal consumer information. Digital rights advocates, including the Electronic Frontier Foundation, have backed the bill, arguing that such pricing undermines fairness, privacy, and price transparency.
The California gas station case may prove a bellwether for how courts and legislators treat AI-assisted pricing coordination going forward — not just in the fuel sector, but across retail industries more broadly.
