Summary

A new lawsuit, filed on Monday, June 22, 2026, in a federal court in Sacramento, accuses numerous California gas station operators, including Walmart, Speedway, and Albertsons, of illegally using an AI tool called Kalibrate Fuel Pricing to artificially inflate gasoline prices. The suit claims Kalibrate's system requires stations to share cost and volume data, enabling them to avoid competition and coordinate price hikes, potentially increasing prices by as much as 30 cents per gallon. This alleged practice, which includes a "restoration" feature for large, contemporaneous price increases, impacts 1,732 stations, including 1,000 ARCO, 400 Circle K, and 150 Speedway locations. The legal action is brought under California's AB 325, a 2025 law prohibiting pricing algorithms that restrain trade by using competitor data to influence prices, against Kalibrate's parent company, Knowledge Support Systems, and the accused operators. California's average gasoline price was \$5.52 per gallon on Monday, the highest in the country.

Key takeaway

For legal professionals advising retail businesses on pricing strategies, this lawsuit underscores the critical risk of using AI algorithms that incorporate competitor data. Your organization must ensure any automated pricing system complies with anti-trust regulations like California's AB 325, which explicitly prohibits algorithms that "restrain trade or commerce." Review your current pricing software for features like "restoration" that could be interpreted as facilitating illegal price coordination, potentially leading to significant legal exposure and penalties.

Key insights

A lawsuit alleges AI-driven pricing algorithms facilitate illegal price fixing among California gas stations, violating a new state law.
