$13.4 billion net worth "Tesla superfan" twice bought NVIDIA(NVDA.US), holding 2 million shares to resist AI bubble claims

After increasing his holdings at the beginning of this month, Tesla (TSLA.US) major individual shareholder and billionaire Leo KoGuan once again fulfilled his market commitment on March 7th. Amid the global sell-off triggered by the Middle East conflict—ranging from bonds to stocks—he completed a second large-scale purchase of NVIDIA (NVDA.US) shares. According to his latest trading updates on social platform X, KoGuan bought an additional 1 million shares of NVIDIA on that day, bringing his total holdings within a week to 2 million shares.

“As promised, I increased my holdings by another 1 million shares of NVIDIA today,” he posted on X last Saturday. It is understood that KoGuan invested about $180 million to buy 1 million shares of NVIDIA on March 3, 2026. After completing his second round of buying, he reiterated his firm stance on the artificial intelligence industry and further elaborated on his investment logic.

He clearly stated that although there is widespread debate over the valuation of tech stocks, he firmly believes that artificial intelligence is not a fleeting market bubble but a sign of a new era, and a core manifestation of his long-held “KQID Time Engine” theory in the real economy.

KoGuan believes that when the market generally shrinks due to external uncertainties, large investors have a responsibility to anchor market confidence by increasing their holdings of quality tech assets, thereby preventing chain reactions caused by irrational sell-offs.

Although, based on Bloomberg’s billionaire index, his wealth is estimated at $13.4 billion, this purchase is not a large amount for him. However, it is a noteworthy move—over the years, most of his net worth has been concentrated in Tesla stock.

While KoGuan’s investments in NVIDIA have accumulated to several hundred million dollars, he emphasizes that his investment focus has not fundamentally shifted. Currently, Tesla shares and U.S. Treasuries still dominate his portfolio, and his continued accumulation of NVIDIA shares is seen as a strategic supplement and reinforcement in the AI computing infrastructure field.

Timing is also a crucial factor. Since the U.S. military action against Iran last month, global stock indices have generally declined. Some worry that if the conflict persists and drags on, asset prices could further fall.

As of last Friday’s close, NVIDIA’s year-to-date decline was about 5%, Tesla’s nearly 12%, while the S&P 500 index fell less than 2%.

Based on NVIDIA’s recent closing price, KoGuan’s recent purchase of shares cost approximately $350 million. Besides expressing hope to “do my part to help stabilize the tense market and wish everyone good luck,” he did not comment further on this acquisition.
