TCI Dumps $8 Billion Microsoft Stake Over AI Disruption Fears
One of the world’s most successful hedge funds has made a striking bet against Microsoft’s future. TCI Fund Management, led by British billionaire Christopher Hohn, reduced its Microsoft holding from 10% of its portfolio at the end of 2025 to just 1% by March 2026 a move that represented the offloading of an approximately $8 billion position the fund had built and held for close to a decade.
The reasoning behind the TCI Microsoft stake exit is pointed. In a quarterly investor letter, Hohn said the fund reduced its investment in Microsoft because rapid progress in AI introduces uncertainty over the company’s competitive position, with primary concerns around the Office productivity software franchise, where AI could change established workflows and lead to the emergence of new productivity platforms. TCI also flagged some risks in Azure.
A Decade of Gains, Then a Swift Exit
The exit is all the more striking given TCI’s history with the stock. The fund benefited from a nearly 400% rise in Microsoft’s stock over a nine-year period, making it one of its most consequential long-term bets. Now, TCI has pivoted its conviction elsewhere. The fund increased its Alphabet stake to 5% of its portfolio from 3%, signalling that Hohn sees Google’s parent as better positioned to survive and benefit from the AI transition.
Microsoft shares eased about 1% on Friday following the news a measured reaction given the sheer scale of the stake sale. TCI, which manages $77 billion and concentrates its bets on just 15 companies, became the world’s most profitable hedge fund in 2025, earning investors $18.9 billion which makes Hohn’s decision to exit Microsoft a signal the market cannot easily dismiss.
For investors, the TCI Microsoft stake reduction raises an uncomfortable question: if AI set to disrupt Microsoft’s most profitable products, who else on Wall Street is quietly arriving at the same conclusion?
