xAI is fighting state AI transparency laws on two fronts at once, and the stakes extend well beyond the company itself.
The California case, xAI v. Bonta, targets AB 2013, which took effect January 1, 2026, and requires AI developers to publish high-level summaries of their training data. The Central District of California denied xAI’s motion for a preliminary injunction on or around March 4-5, 2026, according to court documents in Case 2:25-cv-12295-JGB-SSC. xAI has appealed that denial to the 9th Circuit Court of Appeals, where the case now sits.
The Colorado case arrived ten days ago. On April 9, xAI filed a complaint against Colorado Attorney General Philip Weiser, seeking to block enforcement of the Colorado AI Act (SB 24-205), according to IAPP’s coverage of the complaint. Colorado’s law is itself described as embattled, local leaders are still debating amendments ahead of its effective date, per HRDive’s reporting. That means xAI filed against a law whose final shape isn’t settled.
Both lawsuits assert 1st, 14th, and 5th Amendment grounds. The 1st Amendment argument is the most developed: xAI contends that compelled disclosure of training data constitutes compelled speech, which the government can only mandate under a heightened scrutiny standard. That’s xAI’s legal argument, no court has ruled on the merits. The complaint is also reported to allege a 5th Amendment taking, arguing that mandatory disclosure constitutes appropriation of trade secrets without just compensation, though the specific allegation text hasn’t been confirmed from primary court documents. NetChoice, an industry advocacy group, issued a statement on April 9 calling Colorado’s mandates “vague and amorphous” and asserting they “chill constitutionally protected speech.”
Why it matters: The 9th Circuit’s jurisdiction covers nine states and two territories. A ruling striking down AB 2013 on 1st Amendment grounds wouldn’t automatically invalidate other states’ laws, but it would give every AI company a powerful template for challenging similar disclosure requirements. Several states are watching the 9th Circuit closely, though the specific impact on pending legislation elsewhere remains uncertain.
The transparency question also doesn’t live in a vacuum. The EU AI Act requires transparency about training data for certain AI systems, as does a growing set of proposed frameworks globally. If US courts establish that such requirements are constitutionally suspect as compelled speech, that divergence between US and non-US approaches to AI accountability becomes a permanent structural feature of the regulatory landscape, not a temporary gap.
For AI developers currently subject to California AB 2013: the appeal doesn’t automatically stay enforcement. The injunction denial stands unless the 9th Circuit orders otherwise. Compliance obligations under AB 2013 remain in force while the appeal proceeds.
The immediate question is whether xAI will seek an emergency stay from the 9th Circuit pending appeal, and whether the court grants it. That decision would signal the appellate panel’s initial read on the constitutional questions. Watch for a 9th Circuit procedural order in the coming weeks.
TJS perspective: xAI is building constitutional precedent, not just defending against two compliance obligations. The company is testing whether AI training practices qualify for First Amendment protection at the appellate level, a question no circuit court has answered. The compliance community should treat the 9th Circuit docket in this case as a live regulatory signal, not a background legal proceeding.
