Why a Tesla billionaire just dumped $180M into Nvidia stock

Leo KoGuan, a Singapore-based investor known for his large Tesla stake, said he bought about 1 million shares of Nvidia on Tuesday.

In a post on X, KoGuan, who has previously described Tesla as his core holding, framed the purchase as a vote of confidence in the longer-term AI trade, even as broader sentiment toward the sector has turned jittery.

The timing was the message.

Nvidia had been sliding from recent highs amid a jittery tape, with investors suddenly acting like the AI trade is one crowded exit away from a pileup.

KoGuan’s response was to buy size and tell the “nervous market” to calm down.

“AI is NOT a bubble- it's only the beginning,” he wrote, adding that he planned to buy another 1 million shares.

Stocks didn’t gap 10% on his post, but you could see the ripple.

Nvidia was modestly higher in early Wednesday trading, and Tesla, still the stock most associated with KoGuan’s name, ticked up as well.

He wasn’t rotating out of Musk so much as signaling that the AI drawdown looks more like a shakeout than a top.

KoGuan’s big swing: Tesla loyalty meets Nvidia panic

KoGuan’s origin story is part of the intrigue.

He’s described himself as an ex-retail trader who went all-in on Tesla in 2019, then rode it into the ranks of the company’s most closely watched individual shareholders.

In past posts, he has cited owning roughly 27.7 million Tesla shares, a stake large enough that even small portfolio moves read like a sentiment indicator.

This week, the indicator flashed “buy the fear,” but with a twist.

Nvidia is not a sleepy value name; it’s the market’s AI metronome.

When it sells off, it tends to drag the whole complex with it, from data-center suppliers to anything that looks remotely “AI-adjacent.”

KoGuan chose that moment to do the simplest, loudest thing a bullish investor can do: buy.

One reason his trade matters is that it lines up with how bullish sell-side analysts have stayed, even as price action wobbles.

Rosenblatt’s Kevin Cassidy, for example, reiterated a Buy and lifted his price target to $300 in a recent note, pointing to strong results and the ramp of Nvidia’s Blackwell platform despite ongoing debate about near-term supply chain constraints.

That kind of call is basically a reminder that the bull case isn’t built on vibes, it’s built on orders.

What Wall Street sees that panickers miss

The core thesis hasn’t changed: companies are spending aggressively on AI infrastructure, and Nvidia remains the default supplier of the most important shovels.

Valuation is where the argument gets more heated.

Nvidia isn’t cheap in the traditional sense, but bulls argue the multiple looks more reasonable if earnings keep climbing as fast as the market expects.

Many analysts still rate the stock a buy, even after the pullback, because they see demand expanding beyond training large models for inference.

The bear case is simpler: the market has already priced in a lot of perfection.

Any stumbles like slower AI spending, tougher competition, export restrictions, or a digestion period after a huge run can hit the stock hard.

And on the Tesla side of KoGuan’s ledger, skepticism around EV demand swings and Musk-driven headline risk hasn’t vanished.
