The wider economy

Official statistics, and figures companies publish from their own records, read beside the claims about what happens next. They carry no status of their own, and none measures AI alone; where one is also the reading behind an indicator on this page, its caption says so.

measured

The Census Bureau asks a sample of American firms every two weeks whether they used AI in any of their business functions, and whether they expect to in the next six months; its question changed in late 2025, so the lines start there. Ramp, a company that issues business cards, counts the share of its customers whose spending includes a paid AI tool, which reads a younger, more digital set of firms than the Census sample. They measure different things, so the gaps between the lines are not a measurement of anything.

Crosswalk to the capture lens

  • Adopters (same valve) — BTOS, BBD, Ramp and the Anthropic Economic Index are adoption from both ends.
  • Model (same valve) — Buyers spreading work across several labs is adoption breadth read from the model layer.
  • Labour & consumers (same valve) — People adopting directly: consumer and worker use counted from the household side.
