In the high-stakes world of tech investing, Peter Thiel’s decision to unload his hedge fund’s entire stake in NVIDIA Corp. during the third quarter of 2025 has sparked intense debate among industry insiders. Thiel Macro LLC, the billionaire’s investment vehicle, offloaded shares valued at nearly $94 million, according to regulatory filings. This move came amid growing concerns over an artificial intelligence bubble, with Thiel echoing sentiments he expressed earlier about the sector’s overhyped potential.

Thiel, a co-founder of PayPal and an early backer of companies like Facebook, has long been vocal about technology trends. In a September 2024 appearance at the All-In Summit, he compared the current AI landscape to the internet boom of 1999, stating, ‘AI in 2024 is like the internet in 1999. It’s big, it’s going to be important, and it will transform the world not in 6 months but in 20 years. In AI, Nvidia is making 100% of the profits and everyone else is losing money.’ This perspective, shared via posts on X (formerly Twitter), underscores his caution toward short-term AI exuberance.

The sale, detailed in a 13F filing with the Securities and Exchange Commission, also included a significant reduction in Thiel’s Tesla Inc. holdings by 76%, leaving Apple Inc. and Microsoft Corp. as the fund’s primary bets. Analysts interpret this as a broader retreat from high-valuation AI and electric vehicle plays, amid fears of overinflation in the sector.

Timing the Market: Pre-Earnings Exit

Thiel’s exit from NVIDIA occurred before the company’s blockbuster third-quarter earnings report on November 20, 2025, which exceeded Wall Street expectations and provided forward guidance suggesting $500 billion in revenue visibility. According to Forbes, this performance quieted some critics, but it also raised questions about whether Thiel left money on the table by selling prematurely.

NVIDIA’s shares, which had slipped 2.7% in the days leading up to the earnings amid news of Thiel’s sale and similar moves by investors like Michael Burry, rebounded post-report. Reuters reported that the divestment intensified worries of an AI bubble, yet the earnings call highlighted robust demand for NVIDIA’s chips, driven by data center expansions from hyperscalers like Amazon and Google.

Industry observers on X noted the irony: one post from user Shanaka Anslem Perera warned of an impending collapse, stating, ‘The $20B AI exodus Wall Street missed. Thiel, Burry, Dalio just fled NVIDIA while retail piles in.’ However, NVIDIA’s CEO Jensen Huang countered bubble fears during the earnings call, emphasizing, ‘All compute will become AI compute,’ a quote that has circulated widely in financial discussions.

Echoes of Past Bubbles

Thiel’s move isn’t isolated. Bloomberg highlighted that SoftBank Group Corp. also sold its entire NVIDIA stake for $5.8 billion in the same quarter, signaling a wave of caution among major players. This collective retreat recalls the dot-com era, where Thiel himself navigated successes and pitfalls.

Valuation concerns remain central. NVIDIA, briefly the world’s most valuable company, trades at multiples that some deem unsustainable. CNBC analysis points out that while NVIDIA’s revenue surged, profit margins—though impressive—face pressure from rising competition in AI chip design, including from startups backed by Thiel’s own Founders Fund.

On X, sentiment reflects this divide. A post from Philip Pilkington in January 2025 argued, ‘Maybe, hear me out here, AI was massively overhyped because NVIDIA is one of the last remaining viable American hardware companies.’ Such views gained traction post-Thiel’s sale, with users debating whether the AI hype cycle is peaking or just beginning.

Fund Strategy Shifts

Thiel Macro’s portfolio realignment toward more established tech giants like Apple and Microsoft suggests a pivot to stability over speculative growth. Yahoo Finance notes that this mirrors broader hedge fund trends, where managers are trimming exposure to volatile AI stocks amid geopolitical risks, including U.S.-China tensions affecting chip supply chains.

The fund’s reduced Tesla position, now a smaller holding, aligns with Thiel’s complex relationship with Elon Musk, a fellow PayPal mafia member. While Thiel has praised Musk’s ventures, his actions indicate skepticism about Tesla’s valuation in an increasingly competitive EV market.

Analysts from Investing.com suggest Thiel’s sale could be pure risk management, given NVIDIA’s meteoric rise. Yet, with the stock’s post-earnings bounce, estimates of Thiel’s potential ‘lost’ gains—if he had held—range in the tens of millions, based on share price movements reported by Business Insider.

Broader AI Ecosystem Implications

Beyond Thiel’s fund, the sale underscores fractures in the AI narrative. TipRanks reports growing fears of capital misallocation, with trillions invested in AI infrastructure yielding uneven returns. One X post from Eddy •vry uproftible• highlighted NVIDIA’s CEO touting AI agents as a ‘multi-trillion dollar opportunity,’ contrasting with Thiel’s long-term view.

Energy constraints and supply chain vulnerabilities, particularly Taiwan’s role in chip manufacturing, add layers of risk. A November 17, 2025, X post from Shanaka Anslem Perera warned, ‘Taiwan is the single point of failure,’ amplifying concerns that Thiel may have anticipated.

Despite the earnings beat, not all are convinced. Yahoo Finance quoted market watchers suggesting that while NVIDIA’s $500 billion visibility is impressive, sustaining growth requires breakthroughs beyond current hype cycles.

Investor Sentiment and Future Outlook

On platforms like X, reactions to Thiel’s move vary from admiration for his prescience to criticism for missing the earnings uplift. A post from rakhul noted, ‘When a billionaire insider exits fully, people feel it more than any price target,’ capturing the psychological impact on retail investors.

Bank of America analysts, as reported in a recent Yahoo Finance piece, disagree with Thiel’s caution, maintaining a bullish stance on NVIDIA shares. They argue that AI’s transformative potential justifies high valuations, even as figures like Thiel pull back.

Thiel’s history of contrarian bets—from Palantir to cryptocurrencies—suggests his NVIDIA exit might signal a broader market shift. As AI evolves, his actions serve as a barometer for insiders weighing hype against fundamentals in an era of rapid technological change.
