To compare annualized growth rates, in 2000Q1, nonresidential fixed investment was growing 19.1% according to the 2001Q1 advance vintage, but only 14.4% according to the latest vintage.

Currently, 2026Q2 2nd release investment is growing, 8.2%, down from 10.1% in Q1. GDPNow  today reads 9.1% (annualized) growth for Q3. So, the AI driven boom still looks strong, but recall these numbers will be revised…
