Mark Cuban warns that massive data centre investments by Meta and Alphabet could become redundant if AI efficiency improvements accelerate, comparing the buildout to the fibre network boom that eventually solved the bandwidth problem. He predicts stranded capacity will be repurposed, though he expects the AI downturn to be less systemic than the dot-com bubble.
This Wire brief sits within Fusion42's coverage of AI Infrastructure. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ The Wire takeaway
If compute efficiency doubles in the next three years, the data centre your customer is planning to build will be oversized by then—and you'll be selling into a buyer's market instead. Cuban's fibre precedent matters: when excess capacity hit, vendors who'd bet on scarcity lost hard, and only those with defensible customers or switching costs survived.
