Key Investment Moves by Bill Ackman
Bill Ackman, through his firm Pershing Square Capital, is strategically investing in artificial intelligence (AI) stocks, focusing on companies with significant potential despite recent downturns. As of Q4 2025, Pershing Square’s portfolio is concentrated, consisting of only 10 companies, with Brookfield Corporation (NYSE: BN) making up 18% of the portfolio and serving as Ackman’s largest holding. This company is heavily involved in sectors integral to AI, such as energy generation and data centers.
Ackman’s portfolio also includes Amazon (NASDAQ: AMZN), which constitutes 14% of his investments. He significantly increased his stake during the Q4 downturn. Additionally, he invested nearly $2 billion in Meta Platforms (NASDAQ: META), seizing the opportunity presented by market concerns over its AI expenditures. Conversely, Ackman has begun to sell parts of his investment in Alphabet (NASDAQ: GOOG, GOOGL), which now represents nearly 14% of his portfolio, as its stock valuation appears elevated.
