Headline rule
No comprehensive federal AI statute
EU AI Act (Regulation 2024/1689)
What it requires
The US has no single federal AI law. Binding obligations come from a patchwork of state statutes — California, Colorado, Illinois, Texas and others — overlaid with sectoral federal enforcement by the FTC, EEOC, CFPB and FDA. Multistate operators must comply with the strictest applicable state rule.
The EU AI Act is the world's first comprehensive horizontal AI law, applying a risk-based regime across all 27 member states — and to any company serving EU users. Prohibited-use bans already apply; high-risk system obligations (conformity assessment, technical documentation, human oversight) phase in through August 2, 2026.
