California drivers accuse gas station operators of using AI to boost pump prices — lawsuit seeks damages for antitrust violations

Californians pay the highest gas prices in the U.S., and a proposed class action says that the issue has been exacerbated by an AI tool that smartly squeezes customers for the best profits. A newly filed lawsuit at the Sacramento, ​California, federal court says that gas station operators are using Kalibrate’s AI tool, which uses data from nearby competing gas stations, to drive up prices by as much as 30 ​cents a gallon in some areas, reports Reuters.

On Monday, gas station operators including BP, Circle K, Marathon Petroleum, 7-Eleven, Walmart, and Albertsons were named as defendents in the headlining class action, alongside Kalibrate. By implementing the AI-driven price-optimizing tool, these operators have allegedly violated the Cartwright Act, California’s main antitrust law, as well as Assembly Bill 325. The latter is a California law that was put in place at the start of 2026 to crack down on algorithmic price fixing. An open-and-shut case, then?

Looking at the numbers, it is easy to understand why the Californians have been spurred into legal action. AAA figures suggest that California residents pay an average of $5.58 per gallon for regular, which is already much higher than the $3.93 national average. Where Kalibrate’s AI tools are used to adjust gas pricing, pump prices have risen as much as 30 cents per gallon, say the complaints. The result is some operators charging as much as $7 a gallon, notes the source report.

Gas station operators “have conspired to ​put an end ​to competition”

The key compelling argument behind this class action is quoted by Reuters from the case files. “While families struggle to afford the commute to work, defendants have conspired to ​put an end ​to competition, joining ⁠an AI-powered trust to ensure that no matter where a driver turns, the price for gasoline is artificially ​high,” says the complaint.

Currently, it is easy to argue that the rise of AI hasn’t fulfilled its early promises. Sifting through our headlines, it has sparked the RAMpocalypse, and other key PC components like SSDs and GPUs have also been impacted by AI server demand. Moreover, we have seen huge environmental impacts from those AI servers straining infrastructure that is sometimes already under pressure, like electricity generation and water resources. They also cause heat and noise pollution, so people don’t want to be anywhere near them. Then there are the applications we have seen AI used for, thus far. Instead of cancer cures and smart government, we’ve got higher gas prices and divisive social media bots. The complainants are seeking unspecified damages.

    Free market. I don't see the problem because we have similar things happening with RAM and Storage, all driven up big time in price by AI, in that case AI "demand".

    California levies the highest gas tax in the nation at roughly $0.71 to $0.90 per gallon (depending on local taxes and environmental fees). This is more than double the national average and significantly outpaces other states, which generally range between $0.20 and $0.50 per gallon.

    The components of retail gasoline prices are taxes and fees, distribution and marketing, refining costs, and crude oil prices. Drivers in California pay the highest taxes at the pump, equivalent to $0.90 per gallon (gal) between local, state, and federal taxes as of March 2025.

    Federal taxes—which are the same for each state—account for $0.18 of the $0.90/gal in taxes. The other $0.72/gal is made up of state excise tax ($0.60/gal), state sales tax ($0.10/gal), and an underground storage tank fee ($0.02/gal). California’s state gasoline excise tax is the highest in the United States; the average across all states is $0.28/gal.

    Don't forget CA "only" required custom blend of gas and chasing out large refineries. That couldn't be part of this....

    If they are so democratic and tax loving and their population is tax the rich aligned. Why do the rich still not get taxed? Why are the rich allowed secret purchasing of priority and ownership rights against civil infrastructures built from taxes and tax payers? Do you think at all?

    This seems to be the opposite of "free market".

    This is all the vendors colluding and working together to drive prices higher.

    I thought AI was going to read your license plate, look you up and set a price accordingly to what thye think you'd pay at the pump... To just keep all prices in sync across stations and artifically high, you don't need AI for that.

    By using advanced license plate recognition technology to track vehicles coming in and out of your gas station, you can provide personalized service, reward loyal customers, and even simplify payments.
