US dominates AI data centers: 15 of top 20 markets, one state hosts 12

America now dominates the world's largest hyperscale data center markets by a wide margin

Northern Virginia remains enormous despite signs that future development is moving elsewhere

Texas recorded 71% capacity growth, far exceeding the worldwide increase of 36%

The United States has tightened its grip on global hyperscale data center infrastructure, now accounting for 15 of the world's 20 largest markets.

Northern Virginia remains the largest single market, housing nearly 12% of global hyperscale capacity and approximately 250 data centers within Loudoun County.

However, rapid growth elsewhere suggests America's data center expansion is spreading beyond established hubs as power, land, incentives, and opposition influence investment.

America's dominance extends well beyond Northern Virginia

The figures from Synergy Research Group show 20 state or metropolitan markets currently account for 60% of worldwide hyperscale data center capacity.

Northern Virginia and the Greater Beijing Area alone represent 17% of global capacity, followed by Oregon, Iowa, Ohio, Dallas-Fort Worth, Dublin, and Shanghai.

Fifteen of those 20 leading markets are located in America, while Asia-Pacific contains four and Europe has only one, in Dublin.

The balance has shifted further toward America during the past two years, reducing the number of non-US markets within the top 20.

Tokyo and Sydney have fallen from the ranking since last year, alongside South Carolina, while Indiana, Tennessee, and Guangdong entered.

Synergy says America's advantage partly comes from corporate concentration, because 62% of the world's hyperscale operators are headquartered in the U.S.

The country's enormous cloud market also matters, with the US accounting for almost half of revenues across several important segments.

Amazon, Microsoft, and Google have the broadest infrastructure footprints and together control 57% of worldwide hyperscale data center capacity.

“A range of factors influence the choice of location for hyperscale infrastructure, including customers, real estate, power, networking infrastructure, incentives, and political stability,” said John Dinsdale, Chief Analyst at Synergy Research Group.

Texas gains ground as established markets face constraints

Northern Virginia's existing scale remains exceptional, although Dinsdale said the region no longer features as strongly in future development plans.

Loudoun County expects approximately $1.3 billion next year from taxes on data center equipment, according to figures reported by the New York Times.

Yet the economic benefits must be considered alongside incentives, with one earlier report estimating that Virginia's concessions could cost $1.94 billion.

Meanwhile, Texas has emerged as one of the fastest-growing hyperscale markets, with operational capacity increasing by 71% over the past year.

The increase was substantially higher than the worldwide growth rate of 36%, while Indiana, Tennessee, Shanghai, Johor, and Jakarta also recorded strong expansion.

Synergy is currently tracking 915 future hyperscale facilities at different stages of planning, construction, development, or internal equipment installation.

It expects rankings to continue changing, particularly as established markets encounter electricity constraints and communities become more resistant to major developments.

The current figures imply overwhelming US dominance, but the pipeline suggests future growth will depend on whether individual locations can secure sufficient power.
