The global data center market is projected to grow from $269.79 billion in 2025 to $300.64 billion in 2026, on a path toward $699.13 billion by 2034 at an 11.1% compound annual growth rate. The U.S. market alone stood at $134.77 billion in 2025.

Hyperscaler spending is driving the expansion. Capital investments by six U.S. hyperscalers, Microsoft, Amazon, Alphabet, Oracle, Meta, and CoreWeave, approached $400 billion in 2025 and are on track to reach $500 billion in 2026 and $600 billion in 2027. The sector is in what analysts describe as an infrastructure investment supercycle that could require up to $3 trillion by 2030.

Capacity is set to double. Nearly 100 gigawatts of new data center capacity is expected to come online between 2026 and 2030, doubling global capacity and equating to roughly $1.2 trillion in real estate asset value creation. The sector is forecast to expand at a 14% compound annual growth rate through 2030.

The United States dominates the global footprint. As of March 2026, the U.S. hosts 4,011 data centers, far more than any other country. The United Kingdom ranks second with 511, followed by Germany with 507, China with 368, and France with 344.

The numbers describe a buildout of unusual scale, where market value, capital spending, and physical capacity are all climbing at double-digit rates, concentrated heavily in the United States.
