Ruchir Sharma, chairman of Rockefeller International, said the artificial intelligence sector now exhibits all the classic signs of a financial bubble.
This warning comes as global markets continue to pour capital into AI firms, raising concerns that valuations have decoupled from actual economic utility. If the bubble bursts, it could trigger a significant correction across the technology sector and broader equity markets.
Speaking on CNBC’s ‘Squawk on the Street’ program on July 9, 2026 [3], Sharma said his assessment was based on 300 years of market history. He utilized a "four O framework" to evaluate the current boom, which identifies four specific bubble indicators [1]: over-investment, over-valuation, over-hype, and over-leverage.
Sharma said that the AI sector now checks all the classic bubble signs [1]. He said that the combination of these factors creates a fragile environment where market sentiment outweighs fundamental value.
While the technology continues to evolve, Sharma highlighted a specific macroeconomic trigger that could destabilize the sector. He said that higher interest rates could burst this bubble [2]. This suggests that the current valuation levels are heavily dependent on low-cost capital and favorable borrowing conditions.
Beyond the U.S. market, Sharma discussed how different regions are being positioned by global investors. He said that India is seen as an ‘anti-AI play’ by global investors [5]. This positioning suggests that some investors are diversifying away from high-tech volatility by seeking stability in other emerging markets.
The chairman's analysis suggests that while the underlying technology of AI may be transformative, the financial vehicle used to fund it has reached a dangerous peak. He said that the transition from hype to reality often involves a painful period of devaluation.
“The AI sector now checks all the classic bubble signs.”
Sharma's application of a historical framework to modern AI suggests that the current growth is driven more by speculative leverage than sustainable earnings. By identifying the 'four O' markers, he is signaling that the market has entered the final, most volatile stage of a bubble, where any shift in monetary policy—specifically a rise in interest rates—could act as the catalyst for a widespread market crash.
