SpaceXAI's suit challenging California AB 2013, the state's generative-AI training-data disclosure law, is a First Amendment case filed December 29, 2025. The company argues the statute's required training-data documentation is compelled speech and viewpoint discrimination (Source: transformernews.ai).
Background
AB 2013 requires developers of generative AI systems made available in California to publish documentation about the data used to train them. SpaceXAI filed suit against California Attorney General Rob Bonta on December 29, 2025, and was subsequently denied a preliminary injunction (Source: transformernews.ai).
Procedural history
- December 29, 2025 — Complaint filed, asserting compelled-speech and viewpoint-discrimination theories under the First Amendment.
- (date not reported) — Preliminary injunction denied.
- July 23, 2026 — Legal Advocates for Safe Science and Technology filed an amicus brief opposing the suit with nearly 30 co-signatories, including EPIC and Americans for Responsible Innovation (Source: transformernews.ai).
Stakes
Transformer reported that an appeals ruling adopting strict scrutiny for training-data disclosure mandates could imperil transparency provisions in California SB 53, Illinois SB 315, and New York's RAISE Act (Source: transformernews.ai).
