California’s COMPETE Act targets single-firm monopolistic conduct to reshape state antitrust
The California Senate Judiciary Committee has advanced the COMPETE Act, a bill designed to strengthen state-level antitrust enforcement by prohibiting single-firm monopolistic conduct. If enacted, the legislation would align California law with the Sherman Act and potentially impact the operating environments of major technology firms doing business in the state.
Key Takeaways
- AB 1776 prohibits single-firm monopolistic behavior, aligning California with 45 other states and the federal Sherman Act.
- The bill explicitly decouples California antitrust law from federal precedent, instructing courts to interpret state law liberally to maximize deterrence.
- Major tech firms including Google and CalChamber members spent over $6 million lobbying against the bill and related antitrust measures.
- Small businesses with under 100 employees and $10 million in revenue are exempted from the single-firm prohibition to facilitate market entry.
- A crucial hearing by the Senate Appropriations Committee is scheduled for August 3, 2026, before the bill moves to the full Senate floor.
Why It Matters
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.
Additional Context
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.
