Tepper's Appaloosa Expands Stakes in SpaceX and CoreWeave Amid AI Sector Surge

NEW YORK — Billionaire investor David Tepper and his hedge fund, Appaloosa Management, significantly increased their holdings in artificial intelligence-focused entities SpaceX and CoreWeave during the second quarter of 2026. The strategic accumulation marks a notable shift in capital allocation toward private and emerging public infrastructure supporting the AI boom, signaling strong confidence from one of Wall Street's most prominent macro traders.

The moves were disclosed in regulatory filings released on Tuesday, detailing Appaloosa's expanded positions as demand for computing power and satellite connectivity continues to outpace supply. While SpaceX remains a privately held entity, CoreWeave has seen its market valuation soar following its initial public offering earlier this year, driven by contracts with major cloud providers and hyperscalers seeking dedicated GPU clusters.

Wall Street analysts have responded positively to the trend, projecting substantial upside for companies positioned within the AI infrastructure ecosystem. Average price targets for related public equities imply significant growth potential over the next 12 months. Analysts cite a tightening supply of high-performance computing resources as a primary catalyst, suggesting that firms with established manufacturing pipelines and energy access will command premium valuations.

Tepper, known for his contrarian bets on distressed assets and cyclical plays, has increasingly pivoted toward technology infrastructure in recent quarters. Appaloosa's increased stake in CoreWeave aligns with broader institutional interest in the firm's role as a critical intermediary between chipmakers like NVIDIA and data center operators. Similarly, the fund's deepening involvement with SpaceX reflects the growing intersection of orbital internet services and AI data transmission needs.

The investment activity comes as the technology sector faces scrutiny over valuation metrics. Some market observers caution that rapid expansion in AI infrastructure may lead to a capacity glut if demand does not sustain its current trajectory. However, proponents argue that the long-term capital expenditure cycle for AI is just beginning, with global enterprises still in early stages of integrating generative models into core operations.

The filings did not disclose the exact dollar value of the new positions or the specific timing of the trades within the quarter. Appaloosa Management has historically maintained a low profile regarding its private equity allocations, offering limited commentary on individual holdings outside of standard regulatory disclosures.

As the third quarter begins, investors are watching to see if other major hedge funds will follow Tepper's lead in doubling down on these specific AI enablers. The question remains whether the current momentum in the sector can withstand potential interest rate adjustments or regulatory headwinds that could impact capital-intensive projects. Market participants will be closely monitoring upcoming earnings reports and guidance from CoreWeave to gauge if the bullish thesis holds weight as the year progresses.
