Why These 2 AI-Driven Tech Giants Are Attracting Elite Investor Attention in 2026

The Power of Quarterly Filings for Investment Insights

When institutional investors with $100 million or more in assets submit their Form 13F quarterly disclosures to the SEC, they offer a transparent window into the investment decisions of Wall Street’s most accomplished fund managers. These filings reveal which stocks, ETFs, and strategic options are being accumulated or reduced by the market’s shrewdest capital allocators. For retail investors seeking signals about promising opportunities, monitoring these moves from proven money managers can be invaluable.

Beyond Warren Buffett at Berkshire Hathaway, other prominent figures in investment management have built formidable track records. Among them stands Bill Ackman of Pershing Square Capital Management, an investor renowned for his activist approach and ability to identify undervalued assets with significant upside potential. His recent portfolio moves have brought two compelling AI-adjacent opportunities into sharp focus.

Amazon: The Cloud Infrastructure Powerhouse Reshaping Enterprise AI

Amazon (NASDAQ: AMZN) represents one of the most intriguing positions for sophisticated investors examining AI exposure. While the company dominates e-commerce with projections showing it will capture more than 40% of U.S. online retail market share in 2025, its true transformational engine lies elsewhere.

Amazon Web Services (AWS) has become the linchpin of the company’s financial performance. Despite representing just 18.5% of net sales through the first nine months of 2025, AWS contributed an outsized 60.3% of operating income. The critical distinction: as AWS integrates AI capabilities into its platform—offering clients generative AI and large language model solutions—its growth trajectory is accelerating beyond historical norms. AWS maintains a 20% year-over-year sales expansion rate, and AI-driven demand is expected to amplify this momentum.

The valuation proposition proved particularly compelling when institutional money entered positions during mid-2025. Historical precedent shows Amazon shares typically commanded 30 times cash flow multiples throughout the 2010s. Yet during the recent period, shares were accessible at approximately 10 times forward cash flow. Even as of December 9, valuations remained attractive at roughly 12 times projected cash flow for 2026—suggesting the market may still be under-pricing the cash generation potential from AWS’s AI expansion.

Pershing Square Capital Management deployed significant capital here, purchasing 5,823,316 shares during the June quarter, representing approximately $1.3 billion in deployed capital by late September. Beyond AWS, Amazon’s advertising revenue stream and Prime subscription model continue to benefit from billions of monthly marketplace visitors and streaming content consumers—both rich targets for advertisers and subscribers willing to pay premium rates for convenience and content quality.

Uber Technologies: Redefining Mobility and Logistics Through AI Integration

The second AI-enabled investment emerging from elite portfolio activity is Uber Technologies (NYSE: UBER). What many perceive primarily as a ride-sharing application masks a far more sophisticated enterprise.

Uber’s dominance in ride-sharing speaks to its operational excellence: market data indicates it maintains a 68-76% share of U.S. ride-sharing activity between 2017 and 2024, with peaks reaching 76% in March 2024. Yet this moat expands considerably when examining how artificial intelligence underpins the core business. The platform leverages AI for driver-rider matching algorithms, route optimization, demand forecasting, and personalized booking experiences that continuously enhance customer satisfaction.

The broader addressable market presents a substantial growth runway. Global ride-sharing is projected to expand tenfold, reaching approximately $918 billion by 2033 from 2025 levels. However, Uber’s strategic initiatives extend well beyond traditional ride-sharing. The company’s Uber Eats platform and freight logistics operations create diversification that ties corporate performance to broader economic expansion cycles.

Perhaps most intriguing is Uber’s autonomous vehicle ambitions. In July, the company finalized arrangements with electric-vehicle manufacturer Lucid Group and technology firm Nuro to deploy at least 20,000 Lucid Gravity robotaxis across the following six years. This venture represents a frontier opportunity where AI and autonomous systems could reshape transportation economics.

During Pershing Square’s first-quarter activity, Ackman orchestrated the purchase of 30,270,518 Uber shares, establishing it as the fund’s largest single position by market capitalization. The strategy reflects conviction in Uber’s transformation under CEO Dara Khosrowshahi, who restructured a historically unprofitable cash-burning enterprise into a sustainable, highly profitable operation. Combined with AI’s expanding role in optimization and autonomous systems, Uber presents what many consider a compelling AI stock opportunity extending well into 2026 and beyond.

With Pershing Square Capital Management maintaining 11 total holdings valued near $14.6 billion as of September quarter-end, the elevated weighting toward both Amazon and Uber signals considerable confidence in their respective AI-driven growth trajectories.
