Peter Thiel unwinds his entire Nvidia stake

(Sharecast News) - Billionaire investor Peter Thiel has liquidated his entire stake in Nvidia, it emerged over the weekend, marking one of the most high-profile exits yet from the world's most valuable chipmaker at a time of mounting scrutiny over artificial-intelligence valuations.

A regulatory filing from his hedge fund Thiel Macro LLC showed the fund sold all 537,742 Nvidia shares during the third quarter, a holding worth roughly $100m based on the stock's closing price on 30 September.

The move eliminated what had been Thiel's largest position, accounting for close to 40% of his portfolio, and shrank the fund's US equity book from $212m in the second quarter to about $74.4m in the third.

Filings also revealed a steep reduction in his Tesla stake and a full exit from Vistra Energy, while he added positions in Apple and Microsoft.

Thiel's divestment followed a similar decision by SoftBank, which disclosed last month that it had sold its entire Nvidia position for $5.83bn.

The moves came as concerns grew over a potential AI investment bubble, with several prominent investors drawing parallels to the late-1990s technology boom.

Analysis of hedge fund filings shows sentiment toward Nvidia evenly split, with 161 funds increasing their holdings and 160 cutting them in the quarter to September.

Nvidia shares had risen only around 2% since the end of September, despite the group briefly topping a $5trn market valuation, driven by surging demand for its AI infrastructure chips and a 56% jump in data-centre revenue.

However, the broader AI sector has endured sharp volatility, with nearly 70 US-listed AI-related stocks losing a combined $1.8trn in market value since late October.

Thiel, who has long warned that AI enthusiasm may be running ahead of commercial reality, continues to back early-stage AI ventures, including Substrate, Mercor and Cognition AI.
