US filing: Peter Thiel's Thiel Macro sold 537,742 Nvidia shares, worth ~$100M as of September 30, during Q3, amid rising concerns about an AI investment bubble
Peter Thiel's hedge fund Thiel Macro LLC sold off its holdings in Nvidia Corp. during the third quarter, marking another retreat …
Context & Ripple Effects
The sale adds to a mixed ownership picture around Nvidia: SoftBank had built a roughly $3B Nvidia stake earlier in 2025, while Nvidia executives had also sold more than $1B of company stock over the preceding year.
It also sits in a longer pattern of sharp sentiment reversals when investors question whether AI spending will translate into returns, including a 2024 pullback tied to doubts over AI spending. The filing matters as another visible institutional data point rather than evidence, by itself, of a change in Nvidia’s business.
First-order effects
- Thiel Macro removes its Nvidia exposure after selling 537,742 shares during Q3, reducing the fund’s direct participation in further upside or downside in the stock.
- The filing gives investors focused on AI-bubble risk a fresh ownership-flow signal to weigh alongside Nvidia’s operating performance and broader market conditions.
Second-order effects
- Other Nvidia holders and prospective buyers may face greater pressure to distinguish portfolio rebalancing from a fundamental view on AI demand, making quarterly ownership disclosures more salient.
- AI-infrastructure investors may reassess concentration risk across highly valued chip holdings, even as other large investors have accumulated Nvidia shares.
Third-order effects
- If prominent holders continue to trim AI bellwethers amid valuation concerns, capital allocation in the AI infrastructure cycle could become more sensitive to proof of end-user returns rather than expectations of sustained capex alone.
- That would reinforce a more financially driven AI infrastructure market, where ownership flows and volatility can move independently of near-term product or demand developments.
The trend: AI infrastructure is becoming a more financialized trade, with large investors rotating exposure as they test whether AI investment can support elevated expectations.
