California Lawsuit Alleges AI Pricing Software Fuels Gas Collusion

Gas stations accused of AI-enabled price coordination

A federal class action lawsuit filed Monday alleges that major gas station operators in California have used AI-powered pricing software to coordinate fuel prices in violation of state antitrust law. The suit targets Kalibrate, a Manchester, England-based fuel-pricing platform used by retailers operating more than 1,700 California stations.

Defendants named in the complaint include Marathon, Circle K, BP, Speedway, EG America, Walmart, and Albertsons. The plaintiffs describe Kalibrate as functioning like a "central nervous system for a conspiracy to extinguish retail price competition among gas stations."

According to the lawsuit, the software actively discourages competitive pricing by warning users that undercutting rivals would trigger a "downward spiral." Instead, Kalibrate allegedly helps "coordinate high prices" by having stations surrender pricing decisions and share competitively sensitive cost and volume data through the platform.

How algorithmic pricing works

The complaint details specific features it claims facilitate collusion. One tool, described as a "restoration" mechanism, allegedly helps nearly all gas stations in an area raise prices simultaneously and by substantial amounts—without direct communication between competitors.

Research cited in the lawsuit found that algorithmic fuel-pricing software produces average price increases of approximately 6 cents per gallon. In markets with widespread adoption of the technology, increases reached as high as 30 cents per gallon.

The lawsuit calculates that even a single-cent increase drains $134 million annually from California drivers due to the state's fuel consumption volume.

Why it matters

This case represents a new frontier in antitrust enforcement as pricing algorithms become standard business tools across industries. California already pays the nation's highest gas prices, and the lawsuit arrives as fuel costs have climbed globally. The complaint argues that modern technology enables price-fixing without traditional cartel behavior—"without the cigars, the smoke, or even the room," as the filing states.

The case follows similar algorithmic pricing lawsuits. The Department of Justice has pursued RealPage over rental pricing coordination and Agri Stats over alleged meatpacking price inflation, settling both within the past year. California Governor Gavin Newsom signed legislation last year explicitly applying state antitrust law to pricing algorithms, creating the legal framework for this week's filing.

Seeking damages for California drivers

The proposed class action seeks to represent all California drivers who purchased gasoline at stations using Kalibrate software since June 2022. Kalibrate operates in more than 70 countries and did not respond to requests for comment. None of the named defendants provided immediate responses.

The case details were first reported by the Associated Press.
