California AI Transparency Act Operative August 2 — Statewide Disclosure Requirements Now in Force

California's AI Transparency Act (SB 942, as amended by AB 853) became operative August 2, 2026 for covered generative AI providers, requiring a free AI-detection tool, latent disclosures, and license terms mandating revocation within 96 hours when disclosure capability is stripped. The California rules run in parallel with the EU AI Act's Article 50 obligations, creating a dual-compliance burden for any legal tech company serving California-based firms or generating content that touches EU users. No comprehensive federal AI statute has been enacted; executive orders and procurement memoranda set the federal layer while binding private-sector obligations sit in state law, with Colorado's replacement framework starting January 1, 2027. For legal tech founders operating in regulated markets, the compliance surface is now multi-jurisdictional by default — and the legal liability framework is no longer just a vendor selection concern but a product architecture requirement.
