- • Jones attributes the expected pressure to a surge in equity supply as major technology companies, including OpenAI and Anthropic, prepare to go public following SpaceX's recent IPO.
- • Buybacks, M&A and share retirement supported the market over the past four years, but that support is expected to fade as new issuance and AI infrastructure financing add shares.
- • Early AI-sector weakness is visible: Nvidia fell nearly 3% on October 8, erasing about $170 billion in market value, and Samsung Electronics and SK Hynix dropped 7.4% and 10% on October 13.
- • Jones compares the current environment to 1999 and has said he increased exposure to AI-linked stocks, but he did not specify the timing or severity of a potential correction.
Summary
Billionaire investor Paul Tudor Jones, founder of Tudor Investment Corp., expects 2027 to be one of the most difficult years for the U.S. stock market in decades. In an interview with CNBC's "Squawk Box" reported on October 13, 2026, Jones said the market faces "the most negative flow picture" it has seen since roughly 2002. According to Jones, the main threat is a sharp increase in the supply of shares as large technology companies go public or raise capital.
Jones argues that corporate share buybacks, mergers and acquisitions have supported equities over the past four years by reducing the number of shares available for trading. That support is now changing. Following SpaceX's recent IPO, AI developers OpenAI and Anthropic are preparing to list, and publicly traded technology companies may issue additional stock to fund AI infrastructure expansion. Both developments would increase supply and could pressure prices.
The U.S. market is in its fourth consecutive year of gains, driven largely by enthusiasm for artificial intelligence, and the S&P 500 has more than doubled over that period. Investors are increasingly concerned about inflation, rising bond yields and the possibility of tighter monetary policy from the Federal Reserve. Jones said in May that he had increased his investments in AI-linked stocks and compared current conditions to 1999, before the dot-com bust in 2000. He has warned of a significant decline once the technology boom ends but did not specify timing or magnitude.
Signs of stress in the AI sector are already visible. On October 8, Nvidia shares fell nearly 3%, wiping out roughly $170 billion in market capitalization, while Broadcom dropped more than 4%, Oracle fell 5.5%, and CoreWeave and Nebius each lost about 7%. The selloff followed reports that OpenAI's annualized revenue run rate was around $50 billion, below previously reported figures. On October 13, Samsung Electronics and SK Hynix fell 7.4% and 10%, SoftBank lost 8.5%, and U.S. names including Nvidia, AMD and Broadcom came under pressure. Investors cited competition from Chinese chipmakers, stretched technology valuations and the possibility that AI investment takes longer than expected to pay off.
