AI Index Warning Statistics

AI capability is rising fast, but environmental costs and opacity are growing just as fast.

• Grok 4's estimated training emissions were 72,816 tons CO2e, and AI data center power capacity grew to 29.6GW.
• Water usage for GPT-4o inference could exceed the annual drinking water demand of 12 million people.
• Frontier models have begun to surpass human-level performance on PhD-level science problems, multimodal reasoning, and competition math, but they remain weak at reading time, long-term planning, and sophisticated video generation.

The gap between the US and China has nearly disappeared. As of March 2026, Anthropic's top model held only a 2.7% edge, and the number of AI scholars moving to the US has fallen 89% compared to 2017. Global corporate AI investment surged to $581.7 billion in 2025, with private investment at $344.7 billion, and US AI investment reached $285.9 billion.

Early shocks are already visible in the labor market. Employment of software developers aged 22-25 has dropped nearly 20% since 2024, and the AI transparency index fell from 58 points to 40 points.

Generative AI reached 53% of the world's population within three years, and US consumer benefits are estimated at $172 billion annually. Globally, 59% of respondents are optimistic about AI's benefits, but the US had the lowest trust in regulation at 31%. While 80% of US high school and college students use AI for schoolwork, only half of schools have policies in place, and only 6% of teachers said their school's policy is clear.
