Wall Street Sees AI Bubble Coming and Is Betting on What Pops It

It’s been three years since OpenAI set off euphoria over artificial intelligence with the release of ChatGPT. And while the money is still pouring in, so are the doubts about whether the good times can last.

From a recent selloff in the shares of Nvidia Corp., to Oracle Corp.’s plunge after reporting mounting spending on AI, to souring sentiment around a network of companies exposed to OpenAI, signs of skepticism are increasing. Looking to 2026, the debate among investors is whether to rein in AI exposure ahead of a potential bubble popping or double down to capitalize on the game-changing technology.

“We’re in the phase of the cycle where the rubber meets the road,” said Jim Morrow, chief executive officer of Callodine Capital Management. “It’s been a good story, but we’re sort of anteing up at this point to see whether the returns on investment are going to be good.”

“The credit people are smarter than the equity people, or at least they’re worried about the right thing — getting their money back,” said Kim Forrest, chief investment officer at Bokeh Capital Partners.

Big Tech Spending

Alphabet, Microsoft, Amazon.com Inc. and Meta Platforms Inc. are projected to spend more than $400 billion on capital expenditures in the next 12 months, most of it for data centers. While those companies are seeing AI-related revenue growth from cloud-computing and advertising businesses, it’s nowhere near the costs they’re incurring.

“Any plateauing of growth projections or decelerations, we’re going to wind up in a situation where the market says, ‘Ok, there’s an issue here,’” said Michael O’Rourke, chief market strategist at Jonestrading.
