Bill Ackman's Q2 2025 13F Portfolio: A Strategic Bet on Tech and Real Estate Giants

Bill Ackman’s Q2 2025 13F filing reveals a bold, concentrated strategy centered on e-commerce, cloud computing, and real estate development. With a portfolio valued at $13.7 billion across just 11 holdings, Ackman’s Pershing Square Capital Management has staked its reputation on market leaders poised to capitalize on long-term structural trends [1]. The most striking shift is his $1.3 billion investment in Amazon, now 9.3% of his portfolio, and a 21% increase in Alphabet shares, making the two tech giants collectively 24% of his holdings [2]. This reflects Ackman’s conviction in artificial intelligence (AI) and cloud computing as transformative forces, with Amazon’s AWS and Alphabet’s Google Cloud leading the charge [3].

Ackman’s real estate bets, meanwhile, remain focused on development rather than traditional REITs. Howard Hughes Holdings Inc., a 9.3% portfolio allocation, underscores his belief in urban revitalization and mixed-use projects [4]. Brookfield Corporation, at 18.5% of the portfolio, further diversifies his real estate exposure through infrastructure and alternative assets [5]. While these holdings lack the immediate scalability of tech stocks, they align with Ackman’s thesis of long-term value creation in sectors with durable cash flows.

The portfolio’s concentration raises questions about risk, but Ackman’s track record suggests a disciplined approach. By exiting positions like Canadian Pacific Kansas City and reallocating capital to Amazon and Alphabet, he has demonstrated a willingness to pivot swiftly [6]. His strategy mirrors the “Magnificent 7” narrative, betting that AI will drive exponential growth in cloud infrastructure and e-commerce [7].

Ackman’s moves highlight a broader trend among institutional investors: the prioritization of AI-driven growth over cyclical industries. While his real estate holdings may appear less glamorous, they provide a counterbalance to the volatility of tech stocks. This duality—high-conviction tech bets paired with stable real estate assets—reflects a nuanced understanding of macroeconomic dynamics.
