In a bold move that captured the attention of global markets, billionaire investor Leo KoGuan doubled his stake in Nvidia to a remarkable 2 million shares this March, even as escalating conflict in the Middle East sent shockwaves through financial markets worldwide. According to reporting by Seeking Alpha and other financial outlets, KoGuan’s decision to ramp up his holdings in the semiconductor giant comes at a time when many investors are gripped by uncertainty and fear, with major indices and tech stocks alike suffering notable declines.
KoGuan, best known as one of Tesla’s largest individual shareholders, first made headlines earlier this month when he acquired 1 million shares of Nvidia on March 3, 2026, at a cost of roughly $180 million. Just days later, on March 7, he followed through on a public commitment, snapping up another million shares and bringing his total Nvidia holdings to 2 million. “As promised, I bought another 1 million shares of Nvidia today,” KoGuan announced on his social platform X, echoing his intent to stand firm in the face of market turbulence.
For KoGuan, whose estimated net worth stands at $13.4 billion according to the Bloomberg Billionaires Index, these purchases represent several hundred million dollars in fresh capital invested in Nvidia. Yet, as he’s quick to point out, this bold bet on the future of artificial intelligence (AI) is not a departure from his longstanding investment strategy. Tesla stock and U.S. Treasury bonds still dominate his portfolio, while his growing stake in Nvidia is seen as a strategic reinforcement in the rapidly evolving sector of AI computing infrastructure.
KoGuan’s timing is as noteworthy as the scale of his investment. The purchases came amid a global sell-off triggered by the recent outbreak of war in the Middle East, with the U.S. launching military action against Iran last month. The resulting market jitters have sent asset prices tumbling: Nvidia’s shares have fallen about 5% since the start of the year, Tesla’s nearly 12%, and the S&P 500 index has slipped by less than 2% as of March 6, 2026. Investors—large and small—have scrambled to reassess risk, with many opting to reduce exposure to volatile sectors.
Yet KoGuan has taken a distinctly contrarian approach. Rather than retreating from risk, he has doubled down, arguing that moments of widespread fear are precisely when large-scale investors have a responsibility to anchor market confidence. “I hope to do my small part to help calm the tense market. Good luck to everyone,” KoGuan wrote on X, expressing a sentiment that resonates with many who believe in the stabilizing power of committed, long-term investment.
His confidence in Nvidia and the broader AI sector is rooted in more than just numbers. KoGuan has long advocated for what he calls the “KQID Time Engine” theory—a belief that artificial intelligence represents not a fleeting market bubble, but the dawn of a new era in the real economy. Despite widespread controversy over the high valuation of tech stocks, KoGuan remains steadfast, insisting that AI is the “core embodiment” of this theory and a transformative force for industries around the globe.
“When the market is generally fearful due to external uncertainties, large-scale investors have a responsibility to anchor market confidence by increasing their holdings of high-quality tech assets, thereby preventing chain reactions caused by irrational sell-offs,” KoGuan elaborated, according to reporting from local financial news sources. In his view, strategic investments like his recent Nvidia purchases serve not only his own portfolio, but also play a role in maintaining broader market stability during times of crisis.
Observers have noted that, while KoGuan’s cumulative Nvidia investment is significant, it remains relatively modest compared to the bulk of his wealth, which is still concentrated in Tesla shares. This is hardly surprising: KoGuan has built his fortune largely on the back of Tesla’s meteoric rise over the past decade, and he continues to view the electric vehicle maker as a cornerstone of his investment philosophy. Nevertheless, his recent moves signal a growing conviction that AI and its enabling technologies—such as Nvidia’s cutting-edge chips and computing platforms—are poised to become the next great engine of economic growth.
The context for KoGuan’s investment is, of course, fraught with uncertainty. The Middle East conflict has injected a fresh dose of volatility into already nervous markets, with investors closely watching developments for signs of escalation or resolution. The global sell-off that followed the outbreak of hostilities has hit tech stocks especially hard, leading some analysts to question whether the sector’s sky-high valuations are sustainable in the face of geopolitical risk and rising interest rates.
Still, KoGuan’s actions stand as a counterpoint to the prevailing mood of caution. By increasing his Nvidia stake at a time when many are heading for the exits, he is making a clear statement about his faith in the future of AI—and, by extension, the companies that are building the infrastructure for its continued expansion. As he put it, “Artificial intelligence is by no means a short-lived market bubble, but rather marks the beginning of a new era.”
Market watchers will be paying close attention to how KoGuan’s bet plays out in the months ahead. Nvidia, for its part, remains at the forefront of the AI revolution, supplying the chips and platforms that power everything from data centers to autonomous vehicles. The company’s fortunes are closely tied to the continued growth of AI applications, and investors like KoGuan are betting that demand for its products will only accelerate as AI becomes more deeply embedded in the global economy.
For now, KoGuan’s high-profile purchase has injected a dose of optimism into a market otherwise dominated by anxiety. Whether his confidence proves prescient or premature remains to be seen, but one thing is clear: in a world awash in uncertainty, bold moves like KoGuan’s have a way of shaping not just portfolios, but the broader narrative of where technology—and investment—are headed next.
In these turbulent times, KoGuan’s unwavering belief in AI and his willingness to put substantial capital behind that conviction offer a striking reminder that, sometimes, fortune really does favor the bold.
