Summary
Bill Ackman's hedge fund, Pershing Square Capital Management, has opened a substantial new position in Meta Platforms, disclosing an approximately $2 billion investment that now represents roughly 10% of the fund's capital as of the end of 2025. This marks Meta as the third significant new portfolio addition during the year, joining Amazon and Hertz in Ackman's recent deployment of capital. The disclosure came through Pershing Square's fourth-quarter 2025 13F filings and annual investor presentation, providing institutional investors with detailed visibility into the fund's strategic positioning.
Ackman's investment thesis centers on Meta's dominant market position in digital advertising and artificial intelligence applications. The company commands a user base exceeding 3.5 billion people—nearly half the global population—with daily active users rising 7% year-over-year in the fourth quarter of 2025. Coupled with robust revenue growth of 22% in 2025, Meta presents compelling scale economics that Ackman views as foundational to long-term value creation. Pershing Square highlighted Meta's status as an "essential platform for businesses seeking to maximize their return on ad spend," underscoring the company's indispensability in the digital marketing ecosystem.
The artificial intelligence component of Ackman's thesis reflects Meta's ability to leverage granular user preference and behavioral data to drive more precise, relevant advertising campaigns. The platform's AI capabilities facilitate automated, self-service ad generation tools that reduce friction for advertisers while improving targeting efficacy. This technology moat positions Meta to capture increasing share of global digital advertising budgets as AI-driven automation becomes standard across the marketing industry.
This investment move reflects Ackman's continued rebalancing toward technology and artificial intelligence exposure. Pershing Square simultaneously exited its longtime position in Chipotle Mexican Grill, which had served as a top holding for an extended period. The fund's largest disclosed equity position remains Uber Technologies at $2.97 billion, maintaining significant exposure to platform-based business models with AI and automation tailwinds. The Meta position adds a direct play on AI-driven advertising monetization within a concentrated, conviction-driven portfolio characteristic of Pershing Square's investment approach.
