X.AI LLC v. Bonta
Issue
In *X.AI LLC v. Bonta*, X.AI argues that California's A.B. 2013 — which requires generative AI developers to publicly disclose detailed information about their training data, including dataset sources, data counts, copyright and licensing status, and processing methodology — unconstitutionally compels speech in violation of the First Amendment. The question is whether that disclosure regime goes so far beyond the narrow, deception-correcting mandates the Supreme Court has historically tolerated that it cannot survive even deferential constitutional review, or whether it is the kind of routine commercial transparency requirement that governments may freely impose. X.AI also raises a Fifth Amendment challenge, arguing that compelling disclosure of proprietary training-data details constitutes an uncompensated taking or an arbitrary deprivation of property.
What Happened
X.AI LLC filed this opening brief as Appellant in the Ninth Circuit, challenging a district court ruling that left California's A.B. 2013 (Civil Code §§ 3110–3111) standing. DktEntry 15.2 is the statutory and constitutional text addendum accompanying that brief — a formal component of the opening brief package that reproduces the full text of A.B. 2013 alongside the First and Fifth Amendments. By placing the statute's detailed disclosure requirements directly against the constitutional provisions in the appellate record, X.AI invites the Ninth Circuit to assess the law's breadth without the softening effect of legislative findings or agency interpretation. The main brief argues that A.B. 2013's mandates — covering training-data sources, data volumes, licensing arrangements, synthetic data use, and consumer data presence — are far too extensive and methodologically complex to qualify as the "purely factual, uncontroversial" disclosures that receive deferential treatment under *Zauderer v. Office of Disciplinary Counsel*. X.AI seeks reversal and, presumably, an injunction against enforcement.
Why It Matters
This case is an early test of how First Amendment compelled-speech doctrine applies to AI transparency legislation, a category of regulation that is proliferating rapidly at the state level. The central doctrinal battleground — whether training-data disclosure mandates fall within *Zauderer*'s deferential framework or demand heightened scrutiny under *NIFLA v. Becerra* — is genuinely unsettled, and a Ninth Circuit ruling will carry significant weight for how similar statutes in other states are drafted and litigated. If X.AI successfully argues that characterizing datasets, licensing arrangements, and training methodology requires expressive judgment rather than mere factual reporting, it could substantially narrow the space in which governments may regulate AI transparency without triggering serious constitutional review. Conversely, if California prevails under *Zauderer*, it would confirm broad legislative latitude to compel disclosure from AI developers, potentially accelerating similar laws nationwide.
