Paul Tudor Jones, founder of Tudor Investment Corporation and the Robin Hood Foundation, appeared on CNBC's Squawk Box and Squawk Pod in May 2026 to discuss his market outlook and views on artificial intelligence. Jones stated that he had purchased more AI stocks, comparing the current market environment to October or November 1999 and predicting "another year or two to run and 40% more upside." He also described the U.S. as being in a "sovereign debt bubble," noting that the stock market is "over-equitized" and that buying the S&P 500 at its current valuation has historically led to negative 10-year returns. Jones expressed significant concern about AI safety and regulation. He said that at a recent AI conference, 80% of attendees favored government regulation, up from 20% the previous year, and that the head of a major model company stated, "I can't believe we're not regulated." Jones called for immediate regulation, including mandatory watermarking of AI-generated content, and said that "the biggest problem with AI" is the "build break iterate model," where a catastrophic accident could cause mass casualties. He also discussed the Japanese yen, calling it "grossly undervalued" and citing the election of a new prime minister as a potential catalyst.
