California SB 1000, which modifies existing law on AI disclosure and content provenance data for generative AI systems, was approved by the California Senate Committee on Privacy, Digital Technologies, and Consumer Protection on April 13, 2026, and sent to the Senate Appropriations Committee with a hearing scheduled for April 27, 2026.[1][2]

Background

SB 1000 builds on California's existing AI Transparency Act (Bus. & Prof. Code § 22757 et seq.) enacted in 2024, which requires generative AI systems to provide visible and latent disclosures on AI-generated content. The bill strengthens and expands these requirements, addressing gaps identified during the initial implementation period.[1][3]

Key Provisions

The bill requires clear and conspicuous disclosures identifying content as AI-generated, tailored to the medium (images, video, audio). Specific provisions include:[2][1]

  • Generative AI system providers must offer users options to add visible indicators (labels) on AI-generated images, videos, or audio, plus embed undetectable latent disclosures in the content
  • By January 1, 2027, platforms hosting generative AI systems cannot make available non-compliant systems lacking these disclosure mechanisms
  • Large online platforms must detect compliant provenance data (per standards-body specifications) in distributed content and provide user interfaces to reveal if content was AI-generated, substantially altered by generative AI, or captured by devices with provenance capabilities
  • From January 1, 2028, capture device makers (cameras, phones) must embed latent disclosures by default and offer opt-in visible disclosures

Legislative History

  • February 18, 2026: Referred to Senate Committee on Privacy[1]
  • March–April 2026: Committee consideration[1]
  • April 13, 2026: Approved by Senate Privacy, Digital Technologies, and Consumer Protection Committee[1]
  • April 13, 2026: Sent to Senate Appropriations Committee; hearing scheduled for April 27, 2026[1]

Context

California SB 1000 is part of a broader state effort to combat AI-generated misinformation and deepfakes through content provenance and transparency requirements. The bill follows similar disclosure requirements in California's SB 942 (AI Transparency Act) and complements the federal push for content provenance standards. Other states including Nevada have also advanced AI disclosure and provenance legislation in 2026.[1]
