Amazon.com, Inc. (AMZN) shares traded near $261.21 after rebounding sharply from about $258 during Tuesday's session, with the recovery lifting the stock back above $260 following an early decline. The move came as Pershing Square, the hedge fund led by Bill Ackman, highlighted Amazon's artificial intelligence expansion and retail growth in its second-quarter 2026 investor letter, pointing to accelerating cloud momentum and continued marketplace share gains.

Amazon Stock Rebounds as Trading Momentum Improves

Amazon closed at $261.31 on August 17, giving the company a market value of $2.82 trillion, a valuation that keeps it among the world's most valuable publicly traded companies. The stock gained 5.56% over the past month, while its 52-week return reached 14.60%. Shares moved higher after falling toward $258 earlier in the session.

The rebound placed the $260 level back into focus after the earlier decline, with prices between roughly $261.20 and $261.50 forming the immediate trading range following the recovery. The advance also followed broader gains for the stock during 2026.

Pershing Square reported that Amazon shares gained 14% during the second quarter and 3% year-to-date. The firm, known for its concentrated portfolio and closely followed quarterly letters, also said spending on AWS data centers continued to weigh on the stock. Amazon's operating results, meanwhile, showed stronger growth across both its cloud and retail businesses.

AWS Growth Accelerates With Rising AI Demand

Amazon Web Services recorded revenue growth above 30% in 2026, compared with 20% growth during 2024 and 2025. Pershing Square linked the faster AWS growth to increasing adoption of artificial intelligence services.

AWS remains central to Amazon's technology and cloud business. The unit has historically been Amazon's largest source of operating profit and competes with Microsoft's Azure and Google Cloud for global cloud spending. Amazon has continued expanding data center capacity as demand for cloud computing and AI services increases, and capital spending remains a major infrastructure investment for the company, a dynamic mirrored across big tech as major cloud providers have raised infrastructure budgets to build out AI capacity. Pershing Square said those spending concerns did not reflect Amazon's business resilience.

Amazon also reported strong company-wide results during the first quarter of 2026. Revenue increased 17% year over year to $181.5 billion during the period, and the results showed continued sales growth across Amazon's major operations. Amazon's subsequent quarterly reports will show whether the AWS growth rate, capital spending, and margin trends at the center of Pershing Square's analysis continue at these levels.

Retail Volumes Rise as Amazon Gains Market Share

Amazon's retail business recorded 15% unit volume growth during the first quarter of 2026, an increase Pershing Square identified as the fastest pace since 2021. Because unit volume tracks the number of items sold rather than dollars, it offers a direct read on consumer demand across the marketplace. The retail gains added another growth driver alongside the company's expanding cloud operations.

Amazon's online marketplace remains central to its retail operations across multiple categories and regions. The company continues developing logistics, fulfillment, advertising, and technology services around its retail platform, and these operations support Amazon's broader commerce business and revenue base, with advertising among Amazon's fastest-growing revenue lines in recent years.

Amazon also ranked among the most widely held stocks across hedge fund portfolios in the first quarter. A database cited by Pershing Square showed 353 hedge funds held Amazon shares at quarter-end. That figure compared with 381 portfolios during the previous quarter, which the letter noted for comparison. Such counts are compiled from quarterly 13F filings that institutional managers disclose with the U.S. Securities and Exchange Commission, making shifts in hedge fund holdings publicly visible each quarter.
