Strategy

America’s AI Action Plan (July 2025) sets out 90+ federal actions on innovation, infrastructure and diplomacy. The Genesis Mission for AI in science has $5bn+ in federal commitments across 278 projects (July 2026).

Regulation

No federal AI law. Executive Order 14365 (Dec 2025) set up a DOJ task force to challenge state AI laws. California’s SB 53 on frontier-model transparency has applied since 1 Jan 2026; Colorado replaced its AI Act with a narrower law from 1 Jan 2027.

Compute

Stargate targets 9+ GW across seven US sites by 2029, with Abilene, Texas the first live site (Epoch AI). Nvidia H200 exports to China have been licensed case by case since January 2026.

Key labs

OpenAI, Anthropic, Google DeepMind, Meta, xAI, Microsoft, Nvidia.

Notable models

Every frontier release is tracked on Model releases; the September 2026 flagships are GPT-6, Claude Opus 5.5, Gemini 3.8 and Grok 4.7.

What to watch

The first DOJ lawsuit against a state AI law; SB 53’s first year of enforcement; whether the Abilene site reaches 1.2 GW in Q4 2026.
