Billionaire investor Mark Cuban warned that billions of dollars poured into AI infrastructure could be wasted, likening the current frenzy to the dot-com bubble of the late 1990s.

Details

In remarks reported by 24/7 Wall St., Cuban said "a lot of data centers are going to be turned into pickleball courts," suggesting that the current rush to build data centers may result in overcapacity. The comments come as companies like NVIDIA (NVDA) and Super Micro Computer (SMCI) ramp up AI-related investments.

Context

Cuban sold Broadcast.com at the peak of the dot-com bubble in 1999 for $5.7 billion to Yahoo, giving his warnings weight among investors who remember the subsequent crash. Global spending on data centers is estimated to exceed $200 billion in 2025.

What It Means for Investors
