Harvard economist: Data centers drove nearly all US GDP growth in early 2025

U.S. GDP growth in the first half of 2025 was almost entirely driven by data center investment, with growth at only 0.1% excluding this sector. This technology-related investment accounted for 92% of GDP growth, despite being only 4% of the overall U.S. GDP. Tech giants are investing billions in data centers for AI demand. This surge contrasts with sluggishness in other economic sectors, raising questions about the sustainability of growth driven by a single industry.
