The U.S. S&P Global Composite PMI remained unchanged at 58.4 in September 2026, matching the previous reading and underscoring a sustained period of solid private-sector expansion. According to the latest update released on 5 October 2026, the index held at the same level as in the prior reading for September, indicating broadly stable conditions in both manufacturing and services activity.
With the Composite PMI comfortably above the 50-point threshold that separates expansion from contraction, the data suggest that overall business activity in the United States continued to grow at a robust pace through September. The unchanged reading at 58.4 points to steady momentum rather than an acceleration or slowdown, implying that firms across the economy are maintaining output levels amid ongoing demand.
The stability of the index in September 2026 may be interpreted by market participants as a sign of resilience in the U.S. economy. While the data do not provide detail on underlying components such as new orders, employment, or prices, the headline figure reinforces the view that the private sector is operating in an expansionary environment heading into the final quarter of the year.
