Billionaire Leo KoGuan doubles Nvidia stake to 2 million shares

Billionaire Leo KoGuan said on X he doubled his stake in Nvidia to 2 million shares by buying an additional 1 million shares.

He made the purchase at a time when the war in the Middle East has sparked a global selloff.

He is estimated to have spent roughly US$350 million to acquire the shares.

KoGuan’s US$13.4 billion fortune on the Bloomberg Billionaires Index largely tied to Tesla.

Nvidia has fallen about 5% this year through Friday’s close while Tesla is down nearly 12%.

He wrote on X, “Hopefully, I can contribute a little to calm the nervous market. Good luck all.”

🧠 Food for thought

Implications, context, and why it matters.

Investor Leo KoGuan calls himself Tesla’s third-largest individual shareholder, which puts his Nvidia buy in the hands of a well-known Tesla backer 1.
He says Tesla is “the leading embodied AI on Earth” and argues the market still undervalues AI-driven projects such as the Cybercab and Teslabot 1.
That framing makes his roughly $350 million Nvidia position read as a focused wager across the AI stack. It spans Nvidia chips and Tesla deployments in the physical world 1.
In 2024, KoGuan said he was “no longer all-in-Tesla” and started buying Treasury bills (short-term U.S. government debt) after worrying about a market crash. He later said he remains “mostly” invested in Tesla and T-bills (Treasury bills) 1.

KoGuan bought 2 million shares, which is large for one person. It equals about 0.008% of Nvidia’s 24.3 billion shares outstanding 1.
Big holders still dwarf that position, including Vanguard (a large asset manager) with 2.23 billion shares as of June 30, 2025. CEO Jensen Huang held 922,922,938 shares, or 3.77%, as of March 2025 2.
Recent Nvidia insider activity has run in the opposite direction. Company executives and directors have only sold shares in recent months, including routine planned sales by CEO Huang 3, 4.
KoGuan’s stake reads as a public expression of confidence in AI. Nvidia ownership still sits mainly with large institutions, whose moves can sway the stock more than any individual holding 4.
