Hedge fund billionaire Ray Dalio cautioned that the artificial intelligence bubble is approaching the point where it could burst, driven by climbing interest rates and heavy borrowing by technology firms to finance AI infrastructure, according to a report published by Forbes on October 7, 2026. Speaking at the Forbes Global CEO Conference in Singapore on Wednesday, the founder of Bridgewater Associates, the world's largest hedge fund, described the current situation as a "classic bubble" nearing its breaking point. Dalio, who has a net worth of $18.9 billion and ranks as the 145th richest person globally, has previously warned about froth in the AI market.
Global bond yields have surged to their highest levels in decades, with the U.S. 10-year Treasury yield climbing to its strongest point since 2002, pushing up borrowing costs for companies. Tech companies' enormous expenditures on AI infrastructure have sparked growing unease among investors, many of whom worry that revenue won't justify the scale of investment, though enthusiasm around leading tech firms has propelled both the S&P 500 and Nasdaq 100 higher. Dalio's net worth figure and global ranking were current as of 10:30 a.m. on Wednesday, according to Forbes' Real-Time Billionaires list.
Dalio warned that "we're in the part of the cycle that is before that but approaching that," referring to the moment when the AI bubble could rupture. He pointed to rising interest rates and mounting corporate debt taken on to fund AI as forces that could push the bubble to collapse. The billionaire also flagged additional risks including potential wealth taxes and efforts to turn paper gains into actual tax obligations, noting that "everybody says 'I'm worth a billion dollars' but ok, try to spend that."
This isn't Dalio's first warning shot about the AI sector. In June, he cautioned that the AI market displayed characteristics of a bubble that could eventually pop, arguing that "all great technology changes produce bubbles" as companies either spend heavily to capture market share or fail to invest enough and lose ground. He explained that bubbles burst when investors attempt to capitalize on their holdings, describing the "pricking is the converting of wealth into money." At the Singapore conference, Dalio elaborated on this mechanism: "In order to spend that you have to sell wealth in order to get money—and so the bubble usually pricks at that." The core tension, according to Dalio's analysis, lies in the gap between theoretical net worth and actual liquidity—companies and investors hold assets valued in the billions, but realizing those gains requires selling, which can trigger the very collapse they're trying to avoid as supply floods the market.
Dalio's outlook suggests that the AI bubble's fate hinges on the collision of three forces: tightening monetary conditions as rates climb, the need for companies to generate returns on massive infrastructure investments, and the eventual pressure to convert paper wealth into spendable cash through asset sales. The billionaire's warning carries particular weight given his track record navigating market cycles and his firm's position managing the world's largest hedge fund. For executives weighing AI investments, the challenge becomes threading a needle between building competitive infrastructure and avoiding the kind of overextension that precedes market corrections. The path forward may require a recalibration of expectations, where the pace of spending aligns more closely with demonstrated revenue potential rather than speculative future gains.
