McKinsey projects global data center investment to reach $7 trillion through 2030.
Combined capital expenditures by six major hyperscalers—Amazon, Microsoft, Alphabet, Meta, Oracle and SpaceX—are projected to exceed $1.3 trillion by 2027, according to S&P Global.
With data centers expected to account for 38% of net U.S. electricity consumption growth through 2037, according to NEMA, power is fast becoming one of the biggest constraints.
Those poised to gain the most are the vendors and resellers supplying that infrastructure—and the numbers are already showing up in earnings.
For the second quarter ending June 30, 2026, Schneider Electric, Vertiv and Eaton all reported significant growth.
Schneider Electric’s North American sales rose 23%, helping drive record global revenue.
Vertiv raised its full-year 2026 net sales growth outlook to 31%, while operating profit jumped 44% and adjusted operating profit climbed 51%.
Eaton reported Electrical Americas orders up 41%, with total electrical backlog rising 43%.
That surge is now flowing through the reseller channel as well.
Insight Enterprises reported a 65% increase in consolidated net earnings, while another value-added reseller, Connection, posted a 33.8% increase in net income.
Schneider sits squarely in the physical bottleneck of the AI boom, supplying the power distribution, switchgear and cooling infrastructure required to bring increasingly dense AI computing capacity online.
“It’s a great time to be in the data center business,” said Steve Carlini, Chief Advocate of Data Centers and AI at Schneider Electric. “Ten years ago, data centers were much smaller. But now they all need—the big ones need—their own medium-voltage switchgear.”
Carlini said Schneider expects installed data center capacity to reach about 200 gigawatts globally by 2030, roughly double today’s approximately 100 gigawatts.
McKinsey’s broader forecast is even more aggressive, projecting global data center capacity could nearly triple by 2030 as hyperscalers and other technology companies race to add AI computing infrastructure.
For the companies supplying that buildout, the opportunity extends far beyond simply constructing more data centers. AI is dramatically increasing the amount of electricity that must be delivered to each individual rack.
“We’re going to see it almost doubling every year,” Carlini said of expected rack density.
He pointed to Nvidia’s infrastructure roadmap, with rack power moving from roughly 227 kilowatts toward 400 kilowatts as newer generations of AI systems arrive.
“Once you get to the Rubin Ultra, the industry has to go into what’s called high voltage DC power distribution, which is 800 volts,” Carlini said.
Those escalating power requirements are forcing fundamental changes across data center design, from electrical distribution to cooling. Schneider has already deployed more than four gigawatts of liquid-cooling capacity but it’s going to rapidly increase now that Blackwell Ultras and Vera Rubins are all liquid-cooled, Carlini said.
The shift also increases the importance of the channel partners that design, source, integrate and deploy that infrastructure. With power equipment, cooling systems and other critical components becoming essential to bringing new AI capacity online, access to supply has become as important as access to computing chips.
Carlini said the numbers Schneider is seeing from all the large global internet companies are backed by customer commitments rather than merely long-range projections.
“They give us not only a forecast, but they give us purchase orders,” Carlini said. “The demand for these data centers is actually there and there is no speculation about who is going to go into these facilities.”
