Key point: The rules provide further guidance to controllers subject to the law’s children’s privacy protections.

On October 9, 2025, the Colorado attorney general’s (AG) office announced final revisions to the proposed draft amendments to the Colorado Privacy Act (CPA) rules. The office published draft rules in July and solicited public comments. The final revisions reflect changes to the rules based on those public comments. The office has requested an AG opinion letter for these rules. After the opinion letter is received, the rules will be filed with the secretary of state for publication in the Colorado Register. The rules will become effective 20 days after publication.

In the below article, we provide a brief summary of the changes.

Key point: California lawmakers once again increase the disclosure and transparency requirements for registered data brokers.

On October 8, 2025, California Governor Newsom signed SB 361 into law. The bill amends California’s existing data broker registration law to require data brokers to provide significantly more disclosures regarding their processing activities when annually registering with the California Privacy Protection Agency (CPPA).

This amendment comes shortly after the CPPA board’s recent approval of amendments to the state’s data broker regulations to incorporate the 2023 Delete Act (SB 362), including the creation of an accessible deletion mechanism that data brokers will need to comply with starting in August 2026. Those regulations were filed with the Office of Administrative Law on September 26.

Given these developments, California data brokers will need to engage in additional compliance measures in the coming months. In the below article, we provide an overview of the changes made by SB 361.

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.
