Bill Ackman Makes 2 Billion Dollar Wager on Meta Platforms

Billionaire activist investor Bill Ackman has established a substantial stake in Meta Platforms Inc, valued at approximately $2 billion, according to reports from The Wall Street Journal. The investment represents a significant wager on Meta’s competitive positioning in the artificial intelligence technology sector.

The position was disclosed during a Pershing Square fund meeting on Wednesday and accounts for roughly 10% of the hedge fund’s capital as at the end of 2025, based on historical disclosures. Whilst sizeable within Pershing Square’s concentrated investment strategy, the stake represents only a modest proportion of Meta’s total market capitalisation.

According to the Journal, which cited an investor presentation, Pershing Square commenced accumulating Meta shares in November at an average price of approximately $625 per share. The stock has declined roughly 13% over the preceding six months, driven by investor concerns regarding the magnitude of Meta’s expenditure on artificial intelligence infrastructure, research capabilities, and personnel acquisition.

The investment thesis centres on artificial intelligence’s capacity to augment Meta’s core business operations, including content recommendation systems and targeted advertising capabilities. Ackman also identifies potential opportunities in wearable technologies and AI-powered digital assistants. In its presentation, Pershing Square reportedly stated that Meta’s business model stands among the clearest beneficiaries of AI integration.

The investment arrives as Meta continues reallocating resources towards artificial intelligence initiatives, including workforce reductions within its Reality Labs division. Since 2020, the unit has accumulated losses exceeding $70 billion, attracting investor scrutiny despite Chief Executive Mark Zuckerberg’s commitment of tens of billions of dollars towards AI development and data centre expansion.

Ackman maintains a notably concentrated portfolio approach. Pershing Square held merely 13 positions at the conclusion of 2025, including stakes in Alphabet and Amazon. The firm recently divested longstanding holdings in Chipotle Mexican Grill and Hilton Worldwide.

Pershing Square Holdings, the firm’s principal investment vehicle, generated returns of 20.9% in 2025, surpassing the S&P 500’s total return of 17.9%. However, the fund recorded a decline of 2.5% in January 2026.

Meta shares traded down 2.3% at approximately $653 on Thursday afternoon amid a broader technology sector retreat.
