Modernizes the Cartwright Act to address single-firm anticompetitive conduct and ensure California’s antitrust laws reflect today’s economic realities. Codifies the unanimous recommendations of the California Law Revision Commission following three years of expert study.

KCA Context
Market concentration in tech means a handful of firms control the platforms billions rely on for communication, commerce, and employment. When dominant platforms engage in exclusionary practices (e.g., lowering prices to force out competition with plans to sharply raise prices once competition is eliminated), small businesses owned by people of color and entrepreneurs from underrepresented communities are the first to lose access to markets and customers. Workers in concentrated labor markets face suppressed wages, with low-income workers and workers of color bearing the greatest burden. California’s current antitrust framework cannot reach single-firm conduct, and this bill closes that gap.
