NextFin News - As of February 18, 2026, the global investment community is closely scrutinizing a series of high-profile institutional shifts in Amazon.com Inc. (NASDAQ: AMZN) following the release of Q4 2025 regulatory filings. The data reveals a striking lack of consensus among the world’s most prominent fund managers. According to The Motley Fool, Seth Klarman’s Baupost Group, a firm renowned for its disciplined value-investing philosophy, aggressively purchased Amazon shares during the final three months of 2025. Simultaneously, Bill Ackman’s Pershing Square Capital Management added approximately 3.78 million shares to its portfolio, as reported by Quiver Quantitative. Conversely, Berkshire Hathaway, in what marked Warren Buffett’s final quarter as CEO, liquidated over 90% of its holdings in the e-commerce and cloud giant.
This institutional reshuffling occurs against a backdrop of significant market volatility, with Amazon’s share price declining by 12% since the end of the 2025 reporting period. Despite this price correction, Wall Street analysts remain largely optimistic; Citigroup recently set a price target of $265, while BMO Capital Markets maintains a more aggressive target of $310. The central tension driving these opposing institutional moves is Amazon’s massive pivot toward artificial intelligence. The company is projected to spend $200 billion in 2026, primarily on data center infrastructure to support Amazon Web Services (AWS) and its internal AI initiatives. While Klarman and Ackman appear to view the recent price dip as a value opportunity, the exit by Buffett suggests a cautious stance on the capital-intensive nature of the current AI arms race.
The divergence between Klarman and Buffett is particularly noteworthy because both are traditionally categorized as value investors. Klarman’s entry into Amazon suggests a shift in how "value" is defined in the age of generative AI. By increasing his stake, Klarman is likely betting on the "agentic AI" potential through Amazon’s partnership with Anthropic. Amazon’s integration of AI into its logistics and marketplace provides a moat that pure-play software competitors lack. However, the risk remains that if AI demand fails to meet the scale of the $200 billion infrastructure investment, the resulting depreciation costs could severely compress margins. Buffett’s exit may reflect a preference for businesses with more predictable capital requirements, especially as U.S. President Trump’s trade policies and potential tariffs introduce new variables into global supply chain costs.
Furthermore, Amazon faces a structural threat to its core retail business. The rise of AI-driven search tools like ChatGPT and Gemini could potentially bypass the traditional Amazon search bar, which has long been the starting point for consumer product discovery. To counter this, Amazon is leveraging its logistical scale—a physical advantage that digital-first AI rivals cannot replicate. The company’s ability to offer near-instant delivery remains its strongest defense against search disintermediation. Institutional buyers like Norges Bank and BlackRock, which added 17.3 million and 12.0 million shares respectively in Q4 2025, seem to believe that Amazon’s physical infrastructure will ultimately serve as the essential "last mile" for AI-driven commerce.
Looking ahead, the market will be watching for the next round of 13F filings in May 2026 to see if the 12% price drop in early 2026 prompted further buying from value-oriented funds. If AWS can demonstrate that its AI infrastructure is generating high-margin recurring revenue, the current institutional skepticism may pivot toward a broader accumulation phase. However, if consumer shopping habits shift significantly toward AI agents that prioritize price over Amazon’s ecosystem, the "smart money" exit led by Berkshire Hathaway may be remembered as a prescient move. For now, Amazon remains the ultimate battleground stock, representing a high-stakes wager on the industrialization of artificial intelligence.
