California’s COMPETE Act targets single-firm monopolistic conduct to reshape state antitrust

If enacted, California could dictate global compliance standards for streaming and digital platforms due to its status as the world’s fifth-largest economy. The bill’s rejection of federal 'error-cost' frameworks means conduct considered legal under federal law—such as exclusive distribution deals or bundled services—could face state-level prosecution. This shift effectively fills a perceived vacuum in federal enforcement, potentially forcing platforms like Google and Meta to adopt California-mandated behavioral changes worldwide to maintain operational efficiency. Executives must watch for the final legislative vote by August 31, 2026, and a potential gubernatorial signature by September 30.

The push for the COMPETE Act coincides with a significant surge in California’s antitrust infrastructure. Per Politico Pro in May 2026, Governor Gavin Newsom proposed $25 million in specific budget funding for the California Department of Justice to backfill what he described as a federal retreat from monopoly enforcement. This surge in state-level activity follows a series of federal rulings, including a September 2025 decision by Judge Amit Mehta that imposed behavioral remedies on Google’s search business but stopped short of a structural breakup, citing the industry’s rapid evolution toward generative AI.

Simultaneously, California has observed the failure of even more aggressive proposals. Per the Daily Journal, the BASED Act—which targeted self-preferencing by companies with $1 trillion market caps—stalled in April 2026 after failing to advance from the Senate Privacy Committee. The COMPETE Act, by comparison, emerged from recommendations by the California Law Revision Commission, signaling a more systemic attempt to reform the Cartwright Act to address unilateral pricing and refusal-to-deal strategies that previously escaped state scrutiny.

State-led enforcement is already shifting the media landscape. Per the Los Angeles Times in July 2026, California and other states moved to block the Paramount-Warner Bros. Discovery merger independently of federal signals, highlighting a transition where state attorneys general act as 'enforcers-in-chief.' As noted by Skadden in April 2026, this environment increases legal risks for firms whose pricing and distribution strategies were optimized for a uniform federal standard that no longer governs in California.
