Billionaire David Tepper Is Loading Up on These 3 Artificial Intelligence (AI) Stocks That Have Increased 158% or More

Billionaire investor David Tepper's Appaloosa Management significantly increased its holdings in Amazon (AMZN), Nvidia (NVDA), and Taiwan Semiconductor (TSM) during Q2, signaling strong conviction in the continued, long-term growth of the artificial intelligence sector. This move underscores the belief that the AI infrastructure buildout is far from complete, with AI data center capital expenditures from hyperscalers projected to reach $3-4 trillion globally by 2030. Nvidia and Taiwan Semiconductor are positioned as crucial suppliers for AI computing, while Amazon Web Services (AWS) is highlighted as a key enabler of AI workloads, contributing 53% of Amazon's Q2 operating profits and reflecting its substantial role and profitability in the AI race.

Analysis

Billionaire investor David Tepper's Appaloosa Management increased its Q2 stakes in Nvidia, Taiwan Semiconductor, and Amazon, signaling strong institutional conviction in the longevity of the artificial intelligence buildout. The core thesis is that the market is far from saturated, with projections for AI data center capital expenditures from hyperscalers expected to grow from $600 billion in 2025 to a global total of $3-4 trillion by 2030. Nvidia and Taiwan Semiconductor are positioned as the central hardware pillars of this expansion; Nvidia's GPUs are the dominant computing choice, while Taiwan Semiconductor serves as the essential foundry manufacturing chips for both Nvidia and its competitors, providing broad exposure to the sector's growth. Since the start of 2023, their stocks are up 1,100% and 270%, respectively. Amazon is positioned as a critical infrastructure player through Amazon Web Services (AWS), which enables enterprises to rent rather than own expensive AI hardware. The significance of AWS to Amazon's bottom line is substantial, contributing 53% of the company's Q2 operating profit from just 18% of total revenue, highlighting a shift in the company's value driver from e-commerce to high-margin cloud services. Tepper's fund has underscored this conviction by making Amazon its third-largest holding at a 9.2% weighting.

Key Decisions for Investors

• Given the stated multi-trillion-dollar long-term capex forecasts and significant institutional buying, investors should assess the AI sector as a durable, multi-year theme rather than a short-term trade, despite recent substantial stock gains.
• Consider a diversified investment approach to AI infrastructure that includes not only dominant chip designers like Nvidia but also indispensable suppliers like Taiwan Semiconductor and key cloud platform enablers such as Amazon Web Services to capture value across the ecosystem.
• Re-evaluate Amazon's valuation, placing greater emphasis on the high-margin AWS division, which now drives over half its operating profit, as its growth is a primary catalyst for the stock's performance.
• Investors should monitor hyperscaler capital expenditure reports and AI adoption rates in key regions like Europe and China as leading indicators to validate the aggressive growth trajectory forecasted through 2030.
