US Construction Spending Falls 1.9% in September 2026
Total construction spending dropped to $2.19 trillion in September, down 1.9% from a revised August figure of $2.23 trillion.

Analysts will watch October figures to determine whether September's retreat represents a one-month correction or the early stages of a broader slowdown in the construction sector.
