The U.S. economy expanded at a 3.4% annualized rate in the third quarter, accelerating from 2.2% in the previous quarter, according to the Bureau of Economic Analysis. Investment, household consumption and government spending supported growth; falling exports and rising imports weighed on the total.
BEA identified inventories and equipment as the main sources of investment growth, with computers and related equipment leading the equipment increase. Private domestic demand, measured by consumer spending plus fixed investment, rose at a 4.9% annualized pace.
AI investment and the infrastructure outlook
The Associated Press reported that business investment excluding housing rose 12.7%, including a 37.4% increase in information-processing equipment, as companies continued spending on artificial intelligence. Consumer spending increased 3.8%, while residential investment fell 3.3%.
For infrastructure owners, utilities and developers, the composition of investment matters as much as the headline growth rate. Computing equipment requires supporting power, cooling, connectivity and physical facilities. Infraday’s reading is that those dependencies warrant close attention, while the GDP release alone cannot establish demand for any individual project.
The figures are an advance estimate and will be revised as additional information becomes available. All growth rates above are annualized quarterly rates, not year-over-year changes.

Infraday perspective: Strong equipment spending makes power availability, cooling and network capacity relevant planning considerations. National GDP growth is not evidence that a particular infrastructure project is funded or open for procurement.
