Warren Buffett is buying, Michael Burry is shorting: The AI trade splitting Wall Street

Warren Buffett and Michael Burry, two investors closely watched across global markets, are taking diametrically opposite positions on the artificial intelligence frenzy, setting up a rare, high-stakes clash over whether Silicon Valley’s hottest trade is a once-in-a-generation opportunity or a bubble waiting to burst. Their positions, revealed in recent disclosures and letters, come as concerns about an AI bubble gain mainstream attention while investors continue pouring capital into the sector.

Buffett’s Berkshire Hathaway last month unveiled a large new stake in Alphabet, instantly propelling the Google parent into Berkshire Hathaway’s top 10 holdings. The move is widely seen as an endorsement of Alphabet’s heavy AI investments and the market’s view of the company as a frontrunner in the AI race.

The investment comes at a moment of transition for Berkshire. Buffett announced in May that he will step down as CEO at the end of this year, though he will retain his stock, handing the reins to vice chairman Greg Abel after decades at the helm of a company that began as a Nebraska textile mill and grew into one of the most influential conglomerates in American finance.

Burry doubles down on his skepticism

Michael Burry, however, is moving in the opposite direction. The investor who famously profited from betting against the U.S. housing market in 2008 has taken new short positions in Palantir and Nvidia, two of the highest-profile beneficiaries of the AI boom.

He has been particularly critical of accounting practices across Big Tech, arguing that companies “have been systematically increasing the useful lives of chips and servers, for depreciation purposes, as they invest hundreds of billions of dollars in graphics chips with accelerating planned obsolescence.”Burry is also in a period of transition. Scion Asset Management, his hedge fund, will close by year-end. In a recent investor letter, he wrote that his “estimation of value in securities is not now, and has not been for some time, in sync with the markets.” He has since launched a financial newsletter, Cassandra Unchained, where he continues to express skepticism about the AI boom.

A market split as AI hype peaks

Their opposing moves come as even industry leaders begin to acknowledge stretched expectations. Sam Altman, CEO of OpenAI, has voiced concerns about the pace and scale of speculative fervor surrounding artificial intelligence.

Still, capital continues to flood the sector, and the disagreement between two investors of such high reputation underscores the uncertainty in the market. Buffett turned Berkshire Hathaway into one of the most recognizable names in American investing, while Burry inspired Michael Lewis’s The Big Short and the film adaptation starring Christian Bale.

Now, with both navigating turning points in their own careers, the divergence in their AI positions is emerging as one of the most closely watched splits in the market—one that could signal whether the boom is built on solid ground or heading toward another historic correction.
