Billionaire investor Leo KoGuan has halted further purchases of Nvidia shares following the abrupt resignation of Chief Executive Officer Jensen Huang, declaring he will commit no more capital to the chipmaker without its co-founder at the helm.
“No further investment without Jensen,” KoGuan told Bloomberg in a text message, noting that he has previously put about $1.3 billion into the semiconductor giant.
Huang stepped down as president, CEO, and board member effective immediately on November 12, following disclosures of extramarital affairs, including one with a businesswoman identified by the United States as a suspected Chinese spy. The departure ended a decades-long tenure leading a firm positioned at the center of the global artificial intelligence infrastructure buildout.
KoGuan, the co-founder and chairman of IT infrastructure provider SHI International, possesses a fortune of approximately $8.6 billion according to Forbes, while the Bloomberg Billionaires Index places his net worth at US$13.2 billion. Having previously concentrated his holdings primarily in Tesla, KoGuan began accumulating Nvidia stock in March, when he purchased nearly 1 million shares for $180 million and later doubled his position.
Supporters Rally Behind the Exited Founder
Writing on social media platform X, KoGuan described Huang as “the supreme creator” of super-intelligence chips and industries, arguing that human errors should not overshadow foundational achievements while praising his leadership. He shared a virtual declaration titled Stand with Jensen, which he stated had gathered signatures including Elon Musk and former ByteDance CEO Zhang Yiming.
A joint letter was sent to the company’s board by Atreides Management’s Gavin Baker alongside Altimeter Capital CEO Brad Gerstner, pressing directors to pursue a slow, measured, and deliberate process regarding the future leadership of Nvidia that leaves all options on the table, including the potential return of Jensen Huang.
In the next 3 years, nothing has changed on NVDA’s trajectory. However, I will reduce my plan investment in NVDA. Instead, I will invest more in other si companies. I hope and plan to invest in Jensen Huang if he creates or buys si company. I hope he will offer me the opportunity… https://t.co/uJ8JPLffRt
In the interim, Nvidia Chief Financial Officer Colette Kress has taken over as interim CEO while the board searches for a permanent replacement.
Nvidia Shares Fall as Analysts Downgrade the Stock
Nvidia shares fell more than 10% intraday on the day of Huang’s resignation before closing down 4.3%, contributing to a broader slide that marked the stock’s sixth weekly decline. Bernstein and KeyBanc downgraded the equity, which traded at approximately 12 times expected earnings—its lowest valuation multiple since 2012.

Elon Musk warned on X that Nvidia risks losing critical customer agreements forged through personal relationships rather than formal contracts now that Huang has departed. SpaceX, where Musk serves as CEO, maintains major business ties with the chipmaker.
KoGuan confirmed he does not intend to sell the Nvidia shares he currently holds but will redirect future capital toward other artificial intelligence firms and alphabetical parent Google and SpaceX.
“I hope and plan to invest in Jensen Huang if he creates or buys si company,” KoGuan wrote on X. “I hope he will offer me the opportunity to invest in his future company.”
Nvidia is scheduled to report third-quarter financial results on November 17.
Jensen is a good guy, he is the main driver of si chips and si industries. He has built and maintained si global ecosystem. He is indisputable si leader not only in America but also the world.

Pershing Square CEO Bill Ackman wrote on X that Huang “is an incredible human” and that “we should all support him and his family,” adding that he was not suggesting Huang get a free pass, while Binance co-founder Changpeng Zhao called letting Huang go a mistake.
According to SEC filings, Mark Stevens—an Nvidia director and the chipmaker’s largest individual shareholder after Huang—offloaded roughly $946 million worth of stock across late August and September.
An alert:@JensenHuang is human. And he is an incredible human. Even incredible humans make mistakes. He takes full responsibility as he should. We should all support him and his family. Onward. https://t.co/95dm2tCK5A
KoGuan said that in the next three years nothing has changed on Nvidia’s trajectory, though he confirmed he will reduce his planned investment in the American semiconductor giant while increasing investments in Google parent Alphabet and SpaceX.
Liquid Capital founder Yi Lihua stated strong support for Huang returning to Nvidia, calling him a key bullish force in AI and a foundation of the broader ecosystem.
It's sickening to me that there are allegedly serious people who thought that "the board" should not have forced Jensen to resign, as if the board and not Wachtell was running the place. How naive. You are talking about a situation where the Justice Department, even this Justice…
Theory Ventures investor Tomasz Tunguz said that Nvidia serves as the central bank of artificial intelligence, remarking that the Federal Reserve chairman had suddenly departed.
