Pershing Square CEO Bill Ackman Sells Hilton, Redirects $48 Billion Into AI Amid Market Sell-Off
Wall Street stumbled last week as AI anxiety rattled investors. The S&P 500 slipped 1.5%, the Dow Jones Industrial Average fell 1.4%, and the Nasdaq Composite dropped 2.2%, retreating from record territory as traders reassessed how rapidly artificial intelligence could disrupt entire sectors.
Logistics firms, software providers, insurers, and brokers all felt the tremor. In today’s market, even the debut of a new AI-powered app can briefly erase billions in valuation. Add in mixed economic signals and uncertainty around interest rate policy, and the mood quickly turned cautious.
Yet amid the volatility, one prominent hedge fund manager saw not chaos, but opportunity.
Pershing Square’s High-Conviction Play
Bill Ackman, founder of Pershing Square Capital Management, has built a reputation on concentrated, high-confidence bets. The strategy has delivered: Pershing returned 34% last year, comfortably ahead of the broader market’s gains.
At a recent investor presentation, Ackman revealed a striking move. Pershing amassed a $2 billion stake in Meta Platforms, a position that now represents roughly 10% of the fund’s portfolio.
The scale alone signaled conviction. While many investors are trimming exposure to tech amid AI spending concerns, Ackman appears to be leaning into the turbulence rather than retreating from it.
Betting on Meta’s AI Machine
Meta’s stock has surged more than 500% since early 2023, yet it remains down about 12% over the past year. Investors have balked at the company’s projected $115 billion to $135 billion in capital expenditures for 2026, much of it earmarked for AI infrastructure.
Ackman argues that critics are missing the bigger picture. Meta is not simply spending on AI; it is integrating AI to sharpen its advertising engine. In the fourth quarter of 2025, the average price per ad rose 6%, reflecting improved targeting and efficiency powered by machine learning.
Trading at roughly 27 times earnings, Meta sits at a valuation that Ackman views as reasonable compared to other mega-cap tech peers. The thesis resembles a classic value play: a dominant franchise investing heavily today to secure durable cash flows tomorrow.
A Buffett-Style Signal in an AI Age
Ackman’s move evokes comparisons to Warren Buffett, whose philosophy emphasizes patient capital deployed into businesses with enduring competitive advantages. Rather than fear technological upheaval, Ackman appears to believe Meta will harness it.
The broader market may be wrestling with what AI disruption means for traditional industries. Pershing’s wager suggests that some incumbents are not victims of the shift, but architects of it.
In a week defined by retreat, the message from Ackman was clear: volatility can be a signal, not a warning.
