Drivers in California sue gas stations over alleged AI-based price manipulation

Welcome to the AI price fixing lawsuit

Ever feel like gas prices are way too high and nobody can explain why? A big new lawsuit in California says AI might be the hidden culprit. Several major gas station chains are being taken to court for allegedly using artificial intelligence software to secretly inflate prices at the pump.

It names BP, Circle K, Marathon Petroleum, 7-Eleven, Walmart, and Albertsons as defendants. According to the complaint, these companies violated California’s main antitrust law, the Cartwright Act, by using an AI-based tool to coordinate high prices and wring more money from the pockets of consumers.

What is the AI tool behind this case?

At the center of this lawsuit is software called Kalibrate Fuel Pricing, made by Kalibrate, which is also named as a defendant. The complaint says the tool uses data from competing gas stations and AI-driven recommendations to help set fuel prices.

The lawsuit describes Kalibrate as the central nervous system for a conspiracy to extinguish retail price competition among gas stations. The complaint argues the alleged arrangement violates Assembly Bill 325, a California law that took effect January 1, 2026, because it involves a common pricing algorithm allegedly used as part of an anticompetitive conspiracy.

How much more are drivers paying?

The numbers are pretty shocking. The lawsuit claims gas prices rose by as much as 30 cents per gallon in areas where lots of stations use Kalibrate’s AI tool. Some stations allegedly pushed prices to an astronomical $7 per gallon.

Each penny per gallon costs California drivers an extra $134 million every year across the state. The complaint says the AI tool helps ensure that no matter where a driver turns, the gasoline price is artificially high.

California’s already sky-high gas prices

California still has the highest regular gas prices in the country. AAA listed California’s average at $5.38 per gallon on July 5, 2026, compared with a national average of $3.804.

State taxes, fuel rules, refinery costs, and limited fuel-supply connections help explain why California usually pays more than the national average. The lawsuit adds another allegation: that some companies used AI-powered pricing software in ways that may have pushed prices even higher.

Fun fact: California receives no pipeline deliveries from Gulf Coast refiners, and the closure of two in-state refineries since October 2025 has stripped away roughly a fifth of local production capacity.

How does the AI pricing software work?

Kalibrate’s software gathers data from competing stations, including non-public pricing and sales figures. Then it recommends prices that help stations maximize profits while staying competitive.

The complaint calls the alleged arrangement an AI-powered trust. Instead of competitors secretly meeting to fix prices, the shared pricing platform helps companies coordinate without any one station having to move first and risk losing customers.

The restoration feature that raises prices

Here’s something interesting about how the AI allegedly works. The lawsuit mentions a restoration tool inside Kalibrate’s software. This feature helps nearly all gas stations in an area raise their prices contemporaneously and by a large amount.

Research into algorithmic fuel-pricing software found average price increases of about 6 cents per gallon, and up to 30 cents in markets where the tool is widely used. It’s a sophisticated way to reset prices higher without any competitors getting undercut.

Who exactly is being sued?

The lawsuit names a long list of defendants. Besides Kalibrate itself, the gas station operators include BP, Marathon Petroleum, Circle K, 7-Eleven, Walmart, and Albertsons. Also named are Speedway, EG America, and TravelCenters of America.

The complaint says they collectively operate more than 1,700 gas stations across California. The drivers want the court to stop this alleged price-fixing and award damages to everyone who overpaid for gas.

Fun fact: The lawsuit is among the first brought under AB 325, the new California law that prohibits the use of shared pricing algorithms.

What is the lawsuit really arguing?

The drivers aren’t just complaining about high gas prices. They’re arguing that using a shared AI pricing tool is illegal under California law. The Cartwright Act prohibits anti-competitive behavior like price-fixing. Assembly Bill 325 specifically makes it unlawful to use a common pricing algorithm as part of a conspiracy to restrain trade.

The plaintiffs say the AI tool replaces traditional competition with artificial coordination. While families struggle to afford the commute to work, the complaint says, defendants have conspired to put an end to competition.

Similar lawsuits are happening elsewhere

This isn’t the first time AI pricing tools have come under legal fire. The Department of Justice recently sued RealPage for allegedly helping landlords drive up rent prices. There was also a DOJ lawsuit against Agri Stats, a data-sharing company accused of inflating grocery prices through the meatpacking industry.

Both of those cases have been settled. Now, the gas station industry is in the spotlight. These cases show a growing concern about how algorithms can be used to coordinate prices across entire industries without consumers knowing quietly.

The global reach of Kalibrate

Kalibrate isn’t some small startup. The company is based in Manchester, England, and operates in more than 70 countries worldwide. Its clients include major brands like Aldi, The Home Depot, and even restaurant chains. According to the complaint, Kalibrate has shared non-public proprietary pricing information from its customers with prospective clients.

That raises serious questions about how widespread this practice might be. If the AI tool is being used globally, this California lawsuit could have implications far beyond the Golden State.

What does California law say?

Assembly Bill 325 was signed into law by Governor Gavin Newsom on October 6, 2025, and took effect January 1, 2026. It updates California’s Cartwright Act by addressing common pricing algorithms used in anticompetitive agreements.

The law defines a common pricing algorithm as any methodology, including software or other technology, used by two or more persons that uses competitor data to recommend, align, stabilize, set, or otherwise influence a price or commercial term.

This lawsuit is one of the first major tests of that new law, and a win for the drivers could discourage companies from using AI tools to coordinate prices across California.

The bigger picture on AI pricing

Concern over algorithmic pricing prompted California to pass AB 325, but the issue goes far beyond gas stations. The lawsuit is part of a larger wave of litigation and regulatory scrutiny over whether shared or similar algorithms can create de facto price-fixing even without explicit human collusion.

Practitioners building or deploying pricing models should note that legal exposure may hinge on how data is shared, what the optimization objective is, and the governance around automated recommendations.

What happens next?

The case is still in its early stages. The defendants haven’t publicly responded in detail to the allegations yet. Walmart said it is reviewing the complaint and will respond appropriately to the Court. BP declined to comment. Spokespeople for Marathon, 7-Eleven, and Kalibrate didn’t respond to emails seeking comment.

The lawsuit seeks unspecified damages for California drivers who overpaid for gas. For now, it’s a reminder that technology can be used in ways that hurt consumers. AI can make life easier, but it can also quietly drive up costs.
