Citadel founder Ken Griffin warns markets are 'almost certainly' in an AI bubble
Citadel founder Ken Griffin cautioned that investors are 'almost certainly' in an artificial intelligence bubble as companies grapple with heavy spending and unclear productivity gains, though he remains bullish on the sector's long-term survivors.

Investors are "almost certainly" in an artificial intelligence bubble, Citadel founder and CEO Ken Griffin warned in remarks reported across financial media. Griffin observed that companies are pouring heavy capital into the technology while still grappling with how much they will ultimately spend and whether those expenditures are generating tangible productivity gains.[2][9][10][12][13]
Griffin noted that Corporate America is closely scrutinizing bills from developers such as OpenAI and Anthropic and questioning whether the returns justify the massive costs. In hardware, he compared graphics processing units to airline seats, warning that an emerging chip glut could cause GPU prices to collapse just like unsold airline inventory.[2][3][15]
Despite the warning, Griffin emphasized that he remains bullish on the long-term potential of AI and is comfortable with the existence of a bubble. Comparing current conditions to the 1999 dot-com era, Griffin stated that "any radical transformation of our economy is generally intertwined with a bubble." He noted that the internet is now more embedded in daily life than ever, quipping, "I just wish I'd kept my Amazon stock," and argued that companies that survive the bubble will go on to lead the market for decades.[1][4][5][7][8][11][15]

“Almost certainly bubbles” in AI, says Citadel’s Ken Griffin. But he points to 1999: the internet was the great bubble, and it’s more a part of daily life today than ever. He just wishes he’d kept his Amazon stock. He’s right. Every great transformation has its bubble moment, but the companies that survive define the industry for decades. Same deal with AI.
