What happened
Gavin Newsom signed the COMPETE Act (AB 1776) into law on October 1, 2026. The Act amends California’s principal antitrust law, the Cartwright Act, to address single-firm conduct. Starting January 1, 2027, the law prohibits monopolization and monopsonization for companies with 'substantial market power.' Enforcement is limited to the California Attorney General or a district attorney.

Why it matters
The COMPETE Act introduces a broader reach than the existing federal equivalent by targeting companies with significant market power. The law requires proof of 'substantial market power' through direct or indirect evidence, though it does not define how to satisfy this test.
