Marathon Petroleum (US56585A1025) appears in a new California lawsuit that accuses several fuel retailers of using artificial intelligence tools to coordinate and inflate gasoline prices, according to reporting from Reuters and Bloomberg. The company’s shares trade on the NYSE and remain near highs in the S&P 500 energy sector despite the legal headwind.
What Reuters and Bloomberg report
On 22 June 2026, Reuters reported that California’s attorney general filed a civil complaint against BP, Marathon, 7-Eleven and Walmart, alleging that they used third-party AI-driven pricing software to keep gasoline prices elevated in the state. The lawsuit claims the tools analyzed competitors’ prices and recommended increases that allegedly dampened competition, according to the court filing summarized in the coverage.

Bloomberg reported the same day that the complaint seeks civil penalties and an injunction against the alleged conduct, focusing on the use of algorithmic tools in a concentrated fuel retail market. The reports state that the companies, including Marathon Petroleum, are accused rather than found liable, and the matter is expected to take time to work through the courts.
