California AI Transparency Act Amendments Signed Into Law
Algorithmic Accountability: Navigating California’s New Antitrust Frontier
Key point: California’s expansion of its antitrust law — targeting algorithmic pricing and lowering the bar for litigation — signals a major shift in how companies must approach algorithmic pricing tools and compliance.
On October 6, 2025, Governor Gavin Newsom signed into law two significant amendments to California’s Cartwright Act: AB 325 and SB 763. These amendments to the Cartwright Act are the most significant updates to the law in recent years. AB 325 addresses algorithmic price-fixing by prohibiting the use or distribution of pricing algorithms among two or more entities to coordinate prices or commercial terms. SB 763 substantially increases corporate and individual criminal fines for violations. The new laws take effect on January 1, 2026.
California Transparency in Frontier AI Act Signed Into Law
Key point: California enacts first-in-the-nation law focused on regulating frontier artificial intelligence models.
On September 29, 2025, California Governor Gavin Newsom signed SB 53 — the Transparency in Frontier Artificial Intelligence Act (TFAIA) — into law. As explained in the Senate floor analysis, the law “requires large artificial intelligence (AI) developers . . . to publish safety frameworks, disclose specified transparency reports, and report critical safety incidents to the Office of Emergency Services (OES).” The law also “creates enhanced whistleblower protections for employees reporting AI safety violations and establishes a consortium to design a framework for ‘CalCompute,’ a public cloud platform to expand safe and equitable AI research.” The law was hailed by both Newsom and its primary sponsor, Senator Scott Wiener, as striking a proper balance between innovation and placing sensible guardrails on frontier AI models.
