2. AI economy in the US grows at 2,600% annually, yet remains invisible in GDP statistics
ai-safety, ai-products, model-releases - business, safety, research, release - June 2, 2026
What changed? “The AI economy in the United States has been growing at an unprecedented rate, but this extraordinary growth is largely invisible in conventional GDP statistics,” they write. “Treating the AI sector as a coherent economic entity yields preliminary estimates of nominal AI GDP at approximately $250 billion in 2025, growing at roughly 2,600 percent per year in quality-adjusted real terms. [excerpt shortened].
