Bill Ackman and David Tepper led a significant wave of Amazon stock accumulation in Q1 2026, according to 13F filings released May 15. Pershing Square added 1.84 million Amazon shares, lifting Ackman's position by approximately 19%. The fund now ranks Amazon among its largest disclosed holdings alongside Brookfield, Uber, and a newly initiated Microsoft stake. Meanwhile, David Tepper's Appaloosa Management nearly doubled its Amazon position during the quarter, with the 98% increase making the stock the firm's largest disclosed equity holding, valued at roughly ₹7,200 crore. The fund also boosted Uber by 242% and added to Taiwan Semiconductor while trimming Nvidia, Alphabet, and Alibaba. As per latest regulatory filings, Amazon became Appaloosa's largest disclosed equity holding at the end of March, valued at roughly $900 million after the hedge fund increased the position by 98% during the quarter.
Bill Ackman disclosed a new multi-billion dollar stake in Microsoft during Q1 2026, establishing a position worth approximately $2.09 billion at the end of the quarter. According to the latest 13F filing, Pershing Square Capital Management built a Microsoft position valued at around $2.3 billion today, with the firm owning 5.65 million Microsoft shares. Ackman explained that the stock declined following earnings, but described Microsoft's valuation, Azure cloud business, and AI positioning as key drivers behind the investment. In a significant portfolio rebalancing move, Pershing Square sharply reduced its Alphabet position from more than 6.1 million Class C shares in Q4 2025 to roughly 312,000 shares in Q1 2026. Alphabet Class A holdings also fell from roughly 678,000 shares to about 32,000 shares quarter-over-quarter. The filing also showed reduced positions in Uber, Brookfield, and Restaurant Brands compared with the prior quarter.
**Daniel Loeb's Third Point LLC is moving $2.4 billion out of Google as part of a significant portfolio rebalancing move, according to recent regulatory filings. This represents one of the largest single-stock exits by a major hedge fund in recent memory. The move comes as Loeb charts a different path from fellow billionaire investors like Ackman and Tepper, who are positioning heavily in Microsoft and Amazon. The exit from Google reflects Loeb's assessment of the search giant's valuation and growth prospects, marking a notable shift in his technology portfolio strategy. The filing shows Third Point's continued focus on technology investments while reducing exposure to traditional internet advertising-dependent companies.
The latest 13F filings reveal that Amazon emerged as the most repeated overweight name across major hedge fund books, positioning it as Wall Street's top AI trade. This convergence extends beyond Ackman and Tepper, with hedge funds run by Daniel Loeb, Seth Klarman, and Chase Coleman also listing Amazon among their top US holdings. As reported by the filings, this convergence reinforces a shared positioning theme centered on Amazon's resilient e-commerce cash flow, AWS cloud demand tied to AI buildouts, and accelerating digital advertising revenue. The overlap demonstrates institutional conviction in Amazon's long-term growth prospects across multiple investment strategies. Ackman previously bought Amazon following the "Liberation Day" selloff" and added Meta Platforms after concerns around AI-related capital expenditures.
The institutional appetite for Amazon has intensified significantly, with multiple major funds increasing their positions during Q1 2026. Vanguard Group Inc. grew its stake by 1.1%, now owning 832,274,556 shares valued at $158,348,557,000 after purchasing an additional 8,913,959 shares.

Norges Bank established a new position valued at $27,438,011,000, while Northern Trust Corp boosted its holdings by 0.3%. Notably, 72.20% of Amazon's stock is currently owned by hedge funds and other institutional investors, reflecting the broad-based institutional confidence in the company's AI and cloud growth prospects.
