Bill Ackman’s Pershing Square disclosed on February 11, 2026, that it had built a roughly $2 billion stake in Meta Platforms, arguing the company is undervalued and a clear beneficiary of artificial intelligence (AI) integration. The move reshapes the fund’s exposure to Big Tech.
Stake Size and Timing
Pershing Square’s position in Meta Platforms represents about 10.0% of the hedge fund’s capital. The stake was accumulated by the end of December 2025 and disclosed to investors in February 2026, highlighting a concentrated bet on the company.
AI Investment Thesis and Capital Spending
Pershing Square’s investor presentation framed Meta’s $135 billion capital expenditure forecast for 2026 as central to its investment case and expressed support for that spending. The fund cited Meta’s roughly 3.5 billion users and dominant digital advertising business as operating leverage that could amplify AI-driven gains. It argued that market concerns about Meta’s AI-related spending underestimate the long-term payoff. The capital spending plan triggered a brief 8.0% rise in Meta’s share price in January 2026.
The presentation emphasized Meta’s scale and capital allocation as key mechanisms for extracting value from AI investments, reflecting Pershing Square’s concentrated conviction in the company’s AI integration potential.
