Paul Tudor Jones Warns of US Stock Valuation Bubble, Urges Stronger AI Regulation and Legislation

Tudor Investment Corporation founder Paul Tudor Jones said the ratio of total US stock market capitalization to US GDP had risen to a record high. With the broader market trading at elevated price-to-earnings multiples, investors who hold the S&P 500 over the next several years may struggle to earn attractive returns. He also said AI poses unprecedented potential risks and that governments worldwide must close gaps in regulation and legislation.

Jones recently predicted that the AI-driven US stock bull market could continue for another one to two years and disclosed that he had again increased his holdings of AI stocks, without revealing the value of the positions or the exact transaction dates. He warned that the technology industry’s “move fast and fix it later” development model is unsuitable for high-risk AI, and said governments should establish binding rules before the harm escalates.
