Leo KoGuan, one of Tesla’s largest individual shareholders, has announced a significant investment in Nvidia stock, purchasing one million shares of the AI chipmaker. The billionaire tech entrepreneur and founder of IT infrastructure firm SHI International revealed the purchase on social media, stating his conviction that artificial intelligence represents a genuine opportunity rather than a speculative bubble. KoGuan, who lists himself as Tesla’s third-largest individual shareholder on LinkedIn, also indicated plans to acquire additional Nvidia shares.
In a statement to Bloomberg, KoGuan said his Nvidia purchase was intended to provide confidence to a “nervous market.” The AI chipmaker’s stock has declined 4% in 2026 as investors reassess the technology sector’s trajectory following years of unprecedented enthusiasm.
Nvidia Stock Investment Reflects AI Confidence
KoGuan’s decision to invest heavily in Nvidia stock comes at a time when the artificial intelligence trade faces renewed scrutiny. According to the investor, AI technology is “only the beginning” rather than approaching saturation. The market has experienced a shift from the relentless optimism of recent years to a more discerning evaluation that identifies clear winners and losers in the AI space.
The entrepreneur’s public endorsement of Nvidia represents a notable vote of confidence for the semiconductor company. His statement emphasizes a long-term perspective on AI development, contrasting with short-term volatility concerns that have affected technology stocks in early 2026.
Tesla Holdings Remain Despite Past Tensions
Despite his new focus on Nvidia stock, KoGuan confirmed he remains substantially invested in Tesla. The billionaire investor described his portfolio as “mostly in Tesla + T-bills,” according to his statement to Bloomberg. This commitment persists even after KoGuan previously accused Tesla CEO Elon Musk of intentionally damaging the company’s stock price several years ago.
However, KoGuan expressed renewed optimism about Tesla’s future prospects. He wrote that “Tesla’s energy, cybercap and Teslabot are NOT fully priced in,” suggesting the electric vehicle manufacturer’s stock has room for growth. The investor described Tesla as “the leading embodied AI on earth,” connecting his AI investment thesis to both his Nvidia and Tesla holdings.
Market Context and Investor Sentiment
The timing of KoGuan’s announcement reflects broader debates about AI valuations and market sustainability. Meanwhile, investors have become more selective about technology investments following three years of AI-driven market enthusiasm. The transition from widespread optimism to careful evaluation has created opportunities for investors who maintain confidence in the sector’s fundamentals.
Additionally, KoGuan’s position as a high-profile Tesla investor adds weight to his market perspectives. His dual commitment to both Tesla and Nvidia stock illustrates a belief in AI applications across multiple sectors, from autonomous vehicles to data center infrastructure.
KoGuan’s investment strategy suggests he anticipates continued AI development will drive returns for both companies. In contrast to market participants reducing technology exposure, the billionaire investor appears to view current uncertainty as a buying opportunity. His statement that “daring investors could still buy Tesla today for the future fortune” indicates he expects patient capital to be rewarded.
The investor has not disclosed a specific timeline for additional Nvidia stock purchases or provided detailed valuation targets. Market observers will likely monitor whether other prominent investors follow KoGuan’s lead in increasing AI-related holdings during the current period of uncertainty.
