Summary
Hedge fund manager Ray Dalio warned in a post on social media platform X on Monday that the artificial intelligence boom powering Wall Street's technology stocks is "now in the early stages of a bubble," according to Reuters. Dalio co-founded Bridgewater Associates in 1975.
Wall Street's main indexes posted double-digit gains in 2025, marking a third straight year of advances, a run last seen during 2019 to 2021. The gains were fueled by heavy investor demand for AI-linked stocks, which pushed U.S. equity benchmarks to record highs. Global stocks seesawed in the fall as concern over a potential AI stock bubble weighed on sentiment and raised the risk of a selloff. Geopolitical tensions in the Middle East and uncertainty over the Federal Reserve's interest rate path added to investor unease.
Dalio said U.S. stocks significantly underperformed non-U.S. equities and gold in 2025. Gold surged more than 60% last year, emerging markets posted a banner year, and Britain's FTSE 100 outperformed major global markets. "Clearly, investors would have much rather been in non-U.S. stocks than in U.S. stocks, just as they would have preferred to be in non-U.S. bonds than in U.S. bonds and U.S. cash," he wrote.
Dalio flagged Fed policy and productivity growth as major open questions. He said it appears most likely that the newly appointed Fed chair and the FOMC will be biased to push nominal and real interest rates down, which he argued would support prices and inflate bubbles. Analysts expect global investors to seek opportunities in undervalued pockets of financial markets this year as AI bubble concerns push traders to look beyond highly valued technology stocks. Reuters separately reported in late December that Bridgewater's main macro funds delivered record-breaking performance in 2025.
