The California AI Transparency Act, previously SB 942, was enrolled on August 30, 2026, and is awaiting Governor Gavin Newsom's signature by September 30, 2026. GitHub notes that earlier versions would have required providers to revoke licenses under certain circumstances, which is fundamentally incompatible with widely used open source licenses. The final package adopts a narrower notice-and-response approach that resolved this conflict, though implementation questions remain.

GitHub also highlights ongoing work on AB 2713, a follow-up bill intended to refine how the California AI Transparency Act's content provenance requirements apply in practice. The company argues that the underlying law's definitions of 'large online platform' and 'file-sharing platform' could be interpreted to include developer infrastructure like code repositories, creating legal uncertainty. Governor Newsom's signing message last year encouraged follow-up legislation on technical feasibility, and GitHub took a support-if-amended position on AB 2713, though those amendments were not adopted this session.

Beyond AI transparency, GitHub discusses its engagement with age assurance legislation. In Colorado, changes to the Age Attestation on Computing Devices law addressed key concerns about impacts on open source software and developer infrastructure. In Illinois, the Children's Social Media Safety Act was signed into law, with GitHub pledging to continue working with policymakers on amendments to address implementation challenges and unintended impacts on open source.
