Bill Ackman's hedge fund reveals big stake in Meta — 'one of the clearest beneficiaries of AI integration'

Billionaire investor Bill Ackman is making a significant investment in Meta, asserting that the company stands out as one of the primary beneficiaries of artificial intelligence integration. Ackman's Pershing Square hedge fund announced on Wednesday that it has allocated about 10% of its capital, which is around $2 billion, to Meta as of the close of December. In a presentation, the hedge fund expressed confidence that Meta's current stock price does not accurately reflect the company's long-term growth potential driven by AI, describing it as a deeply undervalued asset among global enterprises. As of Wednesday afternoon, Meta's stock was trading at approximately $668 per share, remaining relatively stable in 2026 but down about 7% compared to the previous year. Additionally, Pershing Square disclosed a 13% investment in Amazon by the end of 2025, along with a 2% stake in Hertz from late 2024. While Wall Street's enthusiasm for Big Tech's capital expenditure plans has been lukewarm, Meta's ambitious forecast of $135 billion in spending last month resulted in a brief 8% increase in its share price. Despite the mixed reactions, Ackman's team remains supportive of Meta's strategic direction. They emphasized that concerns regarding the company's AI-related expenditures are underestimating its long-term growth prospects. Furthermore, they highlighted that Meta's user base, which has reached 3.5 billion, continues to grow at a steady rate, positioning the company as a leading force in digital advertising. The presentation concluded by reiterating that Meta's business model is ideally suited to benefit from AI advancements.
