Amazon has once again emerged as one of Wall Street’s most closely watched technology stocks after several billionaire hedge fund managers aggressively increased their positions in the company during the first quarter of 2026.

The renewed institutional interest comes at a pivotal moment for Amazon as the company deepens its commitment to artificial intelligence infrastructure, cloud computing, and next-generation data center expansion. While Amazon’s e-commerce business remains globally dominant, investors are increasingly focused on Amazon Web Services (AWS), which has evolved into the company’s primary engine for profitability and long-term strategic growth.

David Tepper’s Appaloosa Management nearly doubled its Amazon position during the quarter, making the stock the fund’s largest holding. Bill Ackman’s Pershing Square Capital Management added close to two million shares, while Larry Robbins’ Glenview Capital Management elevated Amazon into one of its largest portfolio positions.

Amazon’s AI Infrastructure Strategy Gains Momentum

The surge in institutional buying reflects growing confidence that Amazon is positioning itself at the center of the global artificial intelligence expansion cycle.

AWS reported revenue growth of 28% year-over-year during the first quarter, marking its strongest quarterly growth pace in nearly four years. More importantly for investors, AWS generated approximately 59% of Amazon’s total operating profits, reinforcing the cloud division’s role as the company’s financial backbone.

The AI boom has dramatically increased demand for computing power, storage capacity, and large-scale cloud infrastructure. Major corporations, startups, and governments are rapidly scaling their AI capabilities, forcing hyperscalers like Amazon to invest heavily in data centers and advanced computing systems.

Amazon plans to spend roughly $200 billion this year on infrastructure expansion, one of the largest capital expenditure programs in corporate history. While such spending may pressure near-term margins, many institutional investors appear willing to accept those costs in exchange for long-term AI market leadership.

The company’s strategy increasingly mirrors a broader shift occurring across the technology sector, where scale, compute power, and cloud ecosystems are becoming critical competitive advantages in artificial intelligence deployment.

Why Billionaires Continue Favoring Amazon

Beyond growth potential, valuation appears to be another major factor attracting high-profile investors.

Although Amazon shares have already climbed roughly 30% since the end of March, many analysts still view the stock as relatively attractive compared to other large-cap technology companies benefiting from the AI trade.

Rather than focusing solely on traditional earnings metrics, institutional investors increasingly evaluate Amazon using operating cash flow due to the company’s aggressive reinvestment strategy. By that measure, Amazon’s valuation remains below many historical averages despite its recent rally.

For hedge funds and long-term institutional investors, Amazon offers exposure to multiple structural growth themes simultaneously, including artificial intelligence, cloud computing, digital advertising, logistics automation, and consumer e-commerce.

The company’s diversified business model also provides a level of resilience that many pure AI-focused companies currently lack. While competition across cloud computing remains intense, AWS continues benefiting from its scale, enterprise relationships, and integrated infrastructure ecosystem.

Wall Street Watches the Next Phase of Amazon’s Expansion

Investor enthusiasm surrounding Amazon increasingly reflects a broader market belief that AI infrastructure spending is still in its early stages.

As companies worldwide accelerate adoption of generative AI tools and advanced automation systems, demand for cloud-based computing resources could continue rising for years. That dynamic positions Amazon as both a direct beneficiary of AI growth and a foundational infrastructure provider powering the broader digital economy.

Still, risks remain. Massive infrastructure spending creates pressure to sustain high growth rates, while regulatory scrutiny, competition from Microsoft and Google, and broader macroeconomic conditions could influence future performance.

Looking ahead, investors will closely monitor whether AWS can maintain its accelerating growth trajectory while improving operating leverage. If artificial intelligence adoption continues reshaping global enterprise spending, Amazon’s aggressive investment cycle may ultimately strengthen its dominance across multiple technology sectors for the remainder of the decade.
