Bill Ackman Concentrates 48% of Portfolio in AI
What happened
Hedge fund manager Bill Ackman now has 48% of his portfolio invested in three artificial intelligence stocks. One of the companies is projected to see its addressable market grow tenfold by 2033. Ackman has also made a significant bet on Meta, signaling strong conviction in AI-driven growth.
Why it matters
- The three stocks are Alphabet (19% of assets), Uber Technologies (20% of assets), and Meta Platforms (roughly 10% of assets). - The company with the projected tenfold market growth is Uber; its global ride-sharing addressable market is forecast to increase from less than $88 billion in 2025 to $918 billion by 2033. - The investment in Meta Platforms was a roughly $2 billion position taken in late 2025, representing about 10% of Pershing Square's capital. - Ackman's firm acquired the Meta stake while other investors were concerned about the company's planned $115-$135 billion in AI-related capital expenditures for 2026. - Pershing Square believes Meta is "one of the clearest beneficiaries of AI integration" and that its share price represents a "deeply discounted valuation." - The Alphabet position, which includes both Class A and Class C shares, was initiated in the first quarter of 2023. - To help fund its pivot toward big tech and AI, Pershing Square exited its long-standing investment in Hilton Worldwide Holdings.
