Bill Ackman's Pershing Square has disclosed a roughly $2 billion position in Meta Platforms, marking a significant new investment by the activist investor. The stake represents one of Ackman's largest bets in recent years and signals confidence in Meta's turnaround strategy under CEO Mark Zuckerberg.

The investment comes as Meta faces multiple challenges including slowing advertising growth, competition from TikTok, and massive spending on its metaverse ambitions. Meta's stock has declined approximately 25% over the past year despite cost-cutting measures and share repurchases. Ackman's move suggests he sees value in Meta's dominant social media platforms and potential for operational improvements.

This investment positions Ackman alongside other prominent investors who have recently expressed optimism about Meta's prospects. The $2 billion stake gives Pershing Square significant influence and could pressure Meta's management to pursue additional shareholder-friendly initiatives. Ackman's track record of successful activist campaigns makes this a closely watched development in the tech sector.
