What specific legal claim do California drivers make against BP, Marathon, 7-Eleven, Walmart, and others in this lawsuit?

California drivers allege that the defendants violated the Cartwright Act—the state's primary antitrust law—by using an AI-based tool from Kalibrate to coordinate high gas prices, thereby eliminating competition and artificially inflating prices at the pump.

What role does the company Kalibrate play in the alleged scheme, and why is it named as a defendant?

Kalibrate is named as a defendant because its AI-based tool—used by the gas station operators—is accused of enabling price coordination by analyzing data from competing stations, which plaintiffs claim facilitated algorithmic price fixing in violation of California’s Assembly Bill 325.
