This article describes a class action complaint. The statements below are unproven allegations. None of the defendants has been found liable, there is no certified class, and nothing to claim at this time. This page is informational and is not legal advice.

What Is This About?

A proposed class action filed June 22, 2026 in the U.S. District Court for the Eastern District of California (Sacramento) accuses some of the largest fuel retailers operating in California — along with the maker of the Kalibrate Fuel Pricing software — of using a shared artificial-intelligence pricing tool to coordinate and inflate gas prices. The case is captioned Casciani et al. v. Knowledge Support Systems, Inc. et al., Case No. 2:26-cv-02211-CSK (initially docketed under intake number 2:26-at-01044). The three named plaintiffs are California drivers from Chula Vista, Homeland and Marysville who say they paid artificially high prices at the pump.

The complaint alleges that competing retailers fed their pricing into a common algorithm and that the software recommended higher prices while discouraging stations from undercutting nearby competitors. Plaintiffs frame this as a modern, algorithm-driven form of price coordination. The defendants have not yet responded in court, and these allegations have not been tested or proven.

Can I Claim? No — nothing to claim yet There is no settlement and no claim form.

Who Was Sued

According to the complaint, the central defendant is Knowledge Support Systems, Inc., the company behind the Kalibrate Fuel Pricing tool. The complaint also names a group of retailers that together are alleged to operate more than 1,700 California gas stations, including:


Naming a company as a defendant is not evidence of wrongdoing. As of publication, the defendants had not filed responses, and several companies contacted by news outlets did not provide comment.

How the Kalibrate Tool Allegedly Worked

Kalibrate Fuel Pricing is marketed as software that helps fuel retailers set prices. The complaint alleges that, in practice, competing retailers using the same tool effectively shared competitively sensitive information and received recommendations that pushed prices upward rather than toward competition. Plaintiffs allege the tool discouraged stations from lowering prices below rivals, characterizing such a move as triggering a "downward spiral," and that it even includes a "restoration" feature that lets stations in a market raise prices together. Given California's fuel volume, the complaint alleges that even a one-cent-per-gallon increase drains about $134 million a year from California drivers, and characterizes the total overcharge from the alleged scheme as a multi-billion-dollar drain on the state's economy.

These are characterizations drawn from the complaint. Kalibrate's developer and the retailer defendants have not admitted any of these allegations, and a court has not ruled on whether the software's use violated any law.

The Law Behind the Case

The complaint brings two counts. Count One alleges a per se violation of California's Cartwright Act — the state's primary antitrust law (Cal. Bus. & Prof. Code §§ 16720, 16729) — as amended by Assembly Bill 325, which took effect January 1, 2026. AB 325 makes explicit that using or distributing a "common pricing algorithm" as part of an unlawful trust or conspiracy violates the Cartwright Act, and California Attorney General Rob Bonta has said it "simply makes it clear that using common pricing algorithms to fix prices among competitors is just as illegal as traditional price fixing." Count Two alleges unlawful and unfair business practices under California's Unfair Competition Law (Cal. Bus. & Prof. Code § 17200). Legal commentators have described this case as one of the first major tests of AB 325.

Plaintiffs seek to represent all persons and entities who purchased gasoline at a Gas Station Defendant's California station using Kalibrate Fuel Pricing from June 22, 2022 to the present. The complaint asks for compensatory and treble (triple) damages, restitution and disgorgement, a permanent injunction, and attorneys' fees, and demands a jury trial. The proposed class has not been certified.

What Happens Next

At this stage there is nothing for consumers to file. The defendants will have an opportunity to respond, likely with motions to dismiss, and the court will eventually decide whether the case can proceed as a class action. Antitrust class actions of this kind typically take years, and many are narrowed or dismissed before any recovery. If the case ever reaches a settlement or judgment with payments to consumers, a claims process and deadline would be announced then — we will update this page if that happens.
