Billionaire Bill Ackman Has 14% of His $11.9 Billion Portfolio Invested in This AI Stock -- and Wall Street Thinks It's Poised to Soar

Bill Ackman's Pershing Square Capital Management has made a significant bet on Alphabet, allocating 14% of its $11.9 billion portfolio to GOOGL/GOOG shares, valued at over $1.67 billion as of Q1 2025. Initiated in Q1 2023, this position has seen shares appreciate over 60%, with Ackman citing Google's long-term AI dominance, data access, and cloud business as key drivers, despite some recent profit-taking. Wall Street largely echoes this bullish sentiment, with 57 out of 68 analysts recommending a 'buy' or 'strong buy,' driven by Alphabet's favorable 18.3x forward P/E ratio and strong AI achievements, including Gemini 2.5 Pro and Google Cloud's growth, despite ongoing antitrust scrutiny and competitive pressures.

Analysis

Pershing Square Capital's maintained conviction in Alphabet, representing 14% of its $11.9 billion portfolio, underscores a significant institutional bet on the company's long-term artificial intelligence dominance. The position, initiated in Q1 2023 and now valued at over $1.67 billion, has yielded a return exceeding 60%, validating the initial contrarian thesis that Google's access to vast data, in-house AI chip design, and cloud infrastructure would secure its AI leadership. Despite recent profit-taking through sales of over 3 million shares across two quarters, Bill Ackman simultaneously increased his Class A shareholding, signaling a nuanced strategy of de-risking while retaining core exposure. This bullish stance is broadly supported by Wall Street, where 57 out of 68 analysts hold a 'buy' or 'strong buy' rating, forecasting an average 12-month upside of approximately 17%. The positive consensus is underpinned by Alphabet's compelling valuation, with a forward price-to-earnings ratio of 18.3—the lowest among the 'Magnificent Seven'—and tangible AI progress, including the strong performance of its Gemini 2.5 Pro model and the AI-driven acceleration of Google Cloud. However, investors must weigh these strengths against significant headwinds, namely the risks posed by ongoing antitrust litigation and emerging competitive threats to its core Search business.

Key Decisions for Investors

• Investors with a long-term horizon could consider Alphabet for AI exposure, given its relatively attractive valuation at an 18.3x forward P/E compared to peers and strong institutional backing.
• It is critical to monitor developments in antitrust proceedings and the competitive intensity in the search market, as any negative rulings or significant market share erosion could materially alter the stock's outlook.
• While the bullish thesis is strong, Ackman's recent profit-taking suggests that managing position size and trimming appreciated holdings could be a prudent risk management strategy for investors with significant gains.
