Stanford's 2026 AI Index Report puts US private AI investment at $285.88 billion in 2025, and the economy chapter shows the United States committing 23 times more private capital to AI than China. The figure sits at the top of a year in which global corporate AI investment more than doubled.

Private investment grew fastest among the categories tracked, rising 127.5 percent and now making up 60 percent of total corporate AI investment. Generative AI led the surge with growth above 200 percent and nearly half of all private AI funding. Newly funded AI companies rose 71 percent, and billion-dollar funding events nearly doubled. In generative AI, US investment exceeded the combined total of China and Europe by a wide margin.

Infrastructure spending is climbing alongside revenue. The report notes that leading frontier companies are reaching meaningful revenue in a short period, while compute spending has also grown sharply year over year. Google reported more than $150 billion in annual capital expenditure in 2025.

Adoption inside organizations continued to widen. Surveyed organizations using AI reached 88 percent in 2025, and generative AI is now used in at least one business function at 70 percent of organizations. AI agent deployment remains in the single digits across nearly all business functions.

Consumers are also seeing value. Estimated US consumer surplus from generative AI reached $172 billion annually by early 2026, up from $112 billion a year earlier. On adoption among the general population, the United States ranks 24th at 28.3 percent, even as it leads in investment and model development.

Labor data shows uneven effects. Employment for software developers ages 22 to 25 has fallen nearly 20 percent since 2024, and one-third of organizations expect AI to reduce their workforce in the coming year.
