Caterpillar, Cummins, Eaton and Ford pivot to AI's power boom
The AI buildout's quiet winners aren't chipmakers — they're the industrial manufacturers retooling factories to feed data-center demand for power equipment. A Wall Street Journal report out this week shows the money is already landing in orders and backlogs, not just strategy decks.
Caterpillar, Cummins, Eaton, and Ford are among the US industrial companies pivoting their businesses to feed a booming market for once-prosaic power equipment: generators, switchgear, transformers, and energy storage for AI data centers. The shift is showing up in hard numbers. Caterpillar is investing $725 million to expand large-engine production, with electricity generation now one of its most profitable businesses. Cummins expects its data-center sales to grow roughly 80 percent to $9 billion by 2030. Eaton's data-center-related sales climbed from 14 percent of its business in 2023 to 21 percent in 2025. And Ford — sitting on excess EV battery capacity — plans to invest $2 billion in a new energy-storage business aimed partly at data centers.
The pattern extends well beyond those four. Vertiv is expanding production of AI-ready cooling equipment after second-quarter sales rose 24 percent year over year, and Schneider Electric says it has grown its data-center factory footprint 270 percent in two years. Corning, meanwhile, signed a Meta deal worth up to $6 billion for optical fiber and is scaling its US optical-connectivity manufacturing tenfold with Nvidia. These are factories, industrial jobs, and supplier networks spread across communities hundreds of miles from the data centers they ultimately feed — the industrial economy's version of the AI capex wave.
We made this case in Deep Dive — Power, not GPUs, now sets the pace of AI — and this is the supply side of that story finally cashing in. The twist is who's winning: not Silicon Valley startups but century-old manufacturers that already knew how to build heavy electrical gear. The uncomfortable question is whether this boom ends like the last one. Corning lived through the telecom fiber bubble, when the underlying technology succeeded spectacularly while suppliers drowned in overcapacity; if every manufacturer expands at once, "picks and shovels" become commoditized and margins collapse before AI demand fully materializes.
What to watch: whether industrial backlogs keep converting into revenue as data-center financing tightens — and whether suppliers with diversification or long-term anchor deals, like Corning's Meta agreement, outlast the ones that just built more plants.
The picks-and-shovels play looks safe until everyone overbuilds — are industrial suppliers repeating Corning's telecom-bust mistake? Tell us in the comments.
