Bill Ackman, founder of Pershing Square Capital Management, sold a portion of his Alphabet stake to invest in AI-focused technology stocks [1, 2].

The move signals a strategic pivot by one of the world's most prominent hedge fund managers toward companies he believes are better positioned to monetize artificial intelligence growth.

Reports indicate that Ackman sold 25% of his stake in the big tech giant [3]. He also reduced some holdings in Amazon as part of a broader portfolio realignment. According to reports, Ackman put new capital to work in the second quarter of the year [2].

The billionaire redeployed the capital into two AI-focused stocks. While sources differ on the exact pairing, some reports identify the new positions as Microsoft and Meta Platforms [2], while others state he built $2.4 billion positions in Microsoft and Amazon [4].

Ackman's focus on Microsoft appears driven by the company's AI revenue run-rate, which is cited at $37 billion [4]. He said these shifts are a way to capture stronger revenue run-rates and margin opportunities within the AI sector [1, 4].

One of the newly acquired tech stocks has seen a significant long-term trajectory, with a reported price increase of 65,100% since its initial public offering [2]. This aggressive reallocation reflects a broader trend among institutional investors seeking to optimize their exposure to the "Magnificent Seven" tech stocks as the AI landscape evolves.

Pershing Square continues to manage its U.S.-based portfolio with a focus on high-conviction bets. The shift away from Alphabet suggests a changing outlook on how the search giant will compete against rivals in the generative AI space, a market where Microsoft has established an early lead through its partnership with OpenAI.

Ackman put new capital to work in the second quarter of the year.

This portfolio shift indicates a lack of confidence in Alphabet's current AI trajectory relative to its peers. By moving billions into Microsoft, Ackman is betting that integrated AI ecosystems and existing enterprise revenue streams will provide more reliable margins than Alphabet's search-centric model during this transition.
