Ray Dalio Warns of Imminent AI Bubble Burst Amid Rising Debt
Bridgewater founder cites climbing interest rates and massive tech borrowing as key risks to the artificial intelligence market expansion.
Ray Dalio, founder of the world's largest hedge fund Bridgewater Associates, has issued a stark warning regarding the current state of the artificial intelligence sector. Speaking to an audience in Singapore on Wednesday at the Forbes Global CEO Conference, Dalio described the AI expansion as having all the hallmarks of a "classic bubble" that is approaching its bursting point. He identified two primary forces driving this potential collapse: mounting debt accumulation and climbing interest rates.
The Mechanics of an Economic Bubble
Dalio explained that the current AI boom is heavily underwritten by borrowed money, which creates a fragile financial foundation as borrowing costs rise. "We're in the part of the cycle that is before that but approaching that," Dalio stated regarding the timing of a potential crash. He also highlighted a second trigger for market instability: the pressure to convert paper wealth into actual cash. According to Dalio, mechanisms such as wealth taxes or other requirements to liquidate unrealized gains can puncture a bubble by forcing investors to sell assets.
Surging Debt Among Tech Giants
The scale of borrowing in the technology sector has accelerated dramatically. Data from Benzinga indicates that major tech companies, including Amazon, Microsoft, Alphabet, Meta Platforms, and Oracle, sold approximately $200 billion worth of investment-grade bonds in just the first six months of 2026. This figure nearly doubles what these five corporations combined issued across all of 2025.
Furthermore, JPMorgan Chase CEO Jamie Dimon has estimated that spending within the hyperscaler ecosystem could reach $700 billion this year, with projections potentially climbing to $1 trillion in 2026. A Morgan Stanley forecast suggests global AI-linked debt issuance is on track to nearly hit $570 billion this year, more than doubling last year's total, as this newspaper reported in Fidelity Strategist Warns AI Boom Is 'Dead Money' Amid $3.3 Trillion Inflationary Risk.
Market Valuations vs. Financial Reality
Despite these warning signs from financial leaders, stock markets have continued to push higher. The S&P 500 and Nasdaq 100 recently hit fresh records driven by enthusiasm over technology earnings. However, this advance is concentrated in a narrow slice of the market; Nvidia, Apple, and Microsoft alone comprise over 21% of the entire S&P 500.
The financial strain on these companies is becoming increasingly apparent. Hyperscaler capital expenditures in 2026 are projected to consume close to 100% of operating cash flows, a significant increase from the ten-year average of 40%. While Bank of America has suggested that bond yields would need to climb considerably higher before posing a genuine threat to the AI trade, Dalio's assessment suggests the pressure is already building toward an inevitable correction.
