TLDRs;
-
KoGuan invests $180M in Nvidia, signaling strong confidence in AI despite the stock’s near-term decline.
-
Tesla investor trims holdings, reallocating funds to Nvidia and short-term U.S. Treasury bills for market protection.
-
Peter Thiel exited Nvidia, highlighting contrasting billionaire approaches to AI and tech stock risk.
-
Nvidia shares slide slightly, reflecting broader investor caution and reliance on a few major data center customers.
Billionaire investor Leo KoGuan, one of the largest individual Tesla shareholders, recently announced a purchase of 1 million Nvidia (NVDA) shares valued at roughly $180 million. The news sparked mixed reactions across markets, as Nvidia stock slid about 1.5% following the announcement despite the large buy.
KoGuan disclosed his acquisition on X, emphasizing that he remains “convinced AI is NOT a bubble” and framing his project under ambitious labels such as “AGI” and “Singularity.”
Residing in Singapore, KoGuan’s pivot toward Nvidia marks a notable departure from his historically Tesla-focused investment strategy. While he has not revealed how much of his Tesla holdings he reduced, market observers note the shift reflects growing caution in managing exposure to single-stock volatility.
Strategic Portfolio Shift Away From Tesla
KoGuan’s Nvidia acquisition follows a broader reallocation of his investment portfolio. Previously concentrated heavily in Tesla and other equities, he has increasingly moved into short-term U.S. Treasury bills. He described this diversification as a protective measure against potential market disruptions reminiscent of the 1929 crash.
This move also indicates a tempered approach to risk after a high-leverage, single-stock strategy in 2020 nearly caused significant losses. By scaling back Tesla exposure while investing in Nvidia, KoGuan appears to be balancing optimism about AI with prudence against sudden market swings.
Billionaire Contrasts Highlight AI Divide
KoGuan’s bullish stance on Nvidia and AI starkly contrasts with other high-profile investors. Notably, Peter Thiel’s Thiel Macro LLC exited all Nvidia positions in its latest 13F filing, citing concerns over an AI-driven market bubble. The divergence between such billionaire strategies underscores the uncertainty surrounding the long-term trajectory of AI-focused stocks and data center-driven growth.

Investors are weighing the potential of a multi-trillion-dollar AI infrastructure buildout against the risk of overvaluation, reminiscent of dot-com-era corrections. KoGuan’s confidence in AI, however, signals a strong belief in the sector’s enduring potential despite short-term stock dips.
Nvidia Faces Near-Term Pressure
Despite the high-profile purchase, Nvidia shares experienced a modest decline following the announcement. Analysts point to several factors affecting the stock, including reliance on a handful of major Big Tech customers for nearly half of its data center revenue and lingering concerns about valuation.
KoGuan’s move, while large, may not immediately counter broader market pressures. However, it illustrates a high-stakes reshuffle in portfolios of wealthy investors navigating the uncertain AI landscape. For Nvidia, the combination of billionaire interest and stock volatility reflects both the excitement and risks inherent in the current AI investment boom.
Bottom Line:
Leo KoGuan’s $180 million Nvidia purchase signals growing confidence in AI innovation, but short-term stock pressure and market caution persist. Divergent strategies among high-profile investors highlight ongoing uncertainty in the sector’s valuation and the balance between opportunity and risk.
