BP, Walmart and Others Sued for Allegedly Using AI Algorithms to Manipulate California Gas Prices
Alina Collins
California drivers filed a class-action lawsuit against BP, Walmart and other operators of over 1,700 gas stations, alleging they used the same AI pricing tool to coordinate higher fuel prices — one of the first cases to invoke the state's new algorithm-antitrust law, with the verdict set to test AI pricing's legal boundaries.
What happened?
California drivers filed a class-action suit Monday in Sacramento federal court against BP, Circle K, Marathon Petroleum, 7-Eleven, Walmart, Albertsons and other gas-station operators.
The core allegation: all defendants used the same pricing tool built by AI firm Kalibrate, which pools competitors' price data to coordinate higher prices. Kalibrate itself is named as a co-defendant.
In plain terms = several gas stations that should be competing against each other let the same "brain" set their prices — and prices went up together, leaving drivers with no cheaper option.
How much were prices inflated?
Plaintiffs cite data showing prices rose by as much as 30 cents per gallon in areas where the AI tool was widely adopted.
Every 1-cent increase costs California drivers an extra $134 million per year. This means → if the 30-cent figure holds, the annual excess burden runs into the billions.
California's average regular gasoline price currently sits at $5.58 per gallon, far above the national average of $3.93. The complaint describes some areas hitting $7 per gallon, calling the level "astronomical."
Why does this lawsuit matter?
California's Assembly Bill 325 took effect on January 1, 2025, specifically targeting algorithmic price manipulation. This case is one of the first to invoke the new law's provisions.
This means → the court's ruling will directly test how much bite the statute actually has — whether "uniform AI-driven pricing" counts as "coordinated conduct" under antitrust law.
This reflects a much larger question: if the answer is yes, algorithmic pricing practices across the entire retail industry — not just gas stations — may face serious legal exposure.
How have the parties responded?
The lawsuit seeks unspecified damages; no dollar figure has been disclosed.
All defendants either declined to comment or did not immediately respond to requests for comment.
In plain terms = the case has only just been filed and defendants haven't shown their hand yet. But the core dispute — whether an AI pricing tool constitutes "coordinated conduct" — is now squarely before the court, and the outcome is worth watching closely.
