According to authoritative data from DataTrack, the annualized quarter-over-quarter growth rate of total U.S. domestic private investment in the first quarter of 2026 was 2.3%, a slight slowdown from 3.3% in the previous quarter. Although some preliminary market estimates indicated stronger investment data, actual revised figures show that high interest rates and inflation have begun to suppress overall expansion. Fortunately, benefiting from the robust capital expenditures of tech giants on AI equipment and intellectual property, private investment maintained positive growth, providing key support for overall Q1 GDP performance.
