The third quarter of 2025 saw a notable repositioning of assets within Thiel Macro LLC, the hedge fund controlled by Peter Thiel. Regulatory filings show the fund divested its entire holding of 537,742 Nvidia shares, a stake valued at well over $100 million. This move represented a significant shift, as Nvidia had previously constituted approximately 40% of the fund’s total portfolio. The sale coincided with new investments in Apple and Microsoft, collectively valued at around $45 million. This strategic reallocation reduced Thiel Macro’s total U.S. equity exposure by more than half, decreasing it from $212 million to $74 million. Such a substantial change by an investor known for his nuanced views on technology trends often prompts closer examination of underlying market dynamics.
Nvidia has been a primary beneficiary of the recent surge in artificial intelligence development, with its chips forming the backbone of many advanced AI models. This dominance propelled the company to a market capitalization of $5 trillion in October, briefly making it the world’s most valuable company. However, the rapid ascent of AI-related valuations has also fueled discussions about a potential market bubble. Concerns have intensified following reports of the company’s involvement in circular deals, where Nvidia makes capital investments in AI startups or cloud providers, often in exchange for commitments from those companies to purchase Nvidia’s chips. These arrangements, which include entities like OpenAI and CoreWeave, have raised questions regarding the sustainability of the chipmaker’s valuation trajectory.
Thiel, a co-founder of PayPal and Palantir, has expressed a more measured perspective on AI compared to some of his Silicon Valley counterparts. He described AI as “more than a nothing burger, and it’s less than the total transformation of our society” in a New York Times interview last year, drawing parallels to the internet’s emergence in the late 1990s. While acknowledging AI’s potential to be transformative and ultimately valuable, he has also cautioned that the technology could be “extremely bubbly,” evoking comparisons to the dot-com crash. His recent portfolio adjustments could be interpreted as a reflection of these broader concerns, suggesting a pivot away from the infrastructure providers that have seen massive growth towards companies poised to integrate AI into consumer products.
The companies Thiel chose to invest in, Apple and Microsoft, offer a different proposition in the evolving AI landscape. They are not merely AI hardware providers but established platforms with vast customer bases and diversified revenue streams. Microsoft, for instance, has deeply integrated AI across its Office suite, Azure cloud services, and Copilot offerings, making it a direct beneficiary of its relationship with OpenAI. Apple, with over 2 billion active devices globally and a robust services business that recently posted record quarterly revenue, possesses a significant distribution advantage. This extensive reach allows these companies to transform AI from a capital expenditure into a tangible consumer product, a model that could prove more resilient in the long term.
Both Apple and Microsoft benefit from business models that extend beyond a singular focus on AI hardware. While Nvidia’s revenue is heavily reliant on sales to a limited number of large tech companies, the diversified portfolios of Microsoft and Apple offer greater stability. Their multifaceted operations, which happen to include AI, provide alternative avenues for growth even if the broader AI investment trend experiences a downturn. This inherent diversification could offer a buffer against market volatility, positioning them differently from a chipmaker whose fortunes are inextricably linked to the demand for AI compute power. The shift in Thiel’s fund suggests a strategic bet on the enduring value of these integrated platforms as the AI narrative matures.
