FROM THE top of the slide, which curves into a little backyard pool, the view as recently as April would have been of lush Ohio farmland, dense forest and pretty clapboard houses. Now it is of six giant weatherproof tents of the type more commonly used by the military to house fighter jets or by aid organisers in disaster zones. These will soon contain perhaps $30bn-worth of cutting-edge semiconductors. Along with a clutch of gas turbines to provide power, they occupy a site the size of an airport terminal. If Meta, the site’s owner, stays on track to bring its “Prometheus” data centre online in 2026, it will dedicate an entire gigawatt (GW) of power—the amount needed to power as many as 1m homes, or roughly the output of a large nuclear reactor—to artificial intelligence.
The mammoth data centres of the future, capable of training frontier ai models in 2030, will not be in the urban clusters in Virginia or California that currently house most of America’s server farms, but in the emerging “Silicon Heartland” of Michigan, Wisconsin and Ohio, or in southern states like Louisiana, Mississippi and Texas. Vast sums of capital—as much as $750bn by Amazon, Google, Meta, Microsoft and Oracle, plus billions more by data-centre specialists like CoreWeave and real-estate developers bankrolled by Wall Street—are being ploughed into investments in these places. An estimated $3trn will go into AI data centres globally between 2026 and 2030, according to Moody’s, an information provider. Much of that is earmarked for America. The money will expand total AI computing capacity, measured in the amount of power consumed by data centres, from just under 12GW in America currently to as much as five times that amount by the end of the decade (see map). And almost everywhere across the country, people of all political stripes are furious about it.
