What the Smart Money Is Selling: Inside the Nvidia 13F Filings Ahead of Earnings

The numbers are clear. In the fourth quarter, four high-profile billionaire investors collectively sold over 4.6 million shares of Nvidia. This isn't a whisper; it's a filing that signals a significant shift in institutional sentiment. The key players? Israel Englander of Millennium Management, who sold 3 million shares, trimming his position 17%, and David Tepper of Appaloosa, who sent 200,000 shares to the chopping block.

This is the kind of move that makes the market sit up. These are not retail traders. These are the savviest money managers on Wall Street, and they are actively reducing their skin in the game. The central question is whether this is mere profit-taking or a deeper signal. After all, Nvidia's stock has rallied nearly 1,200% since the start of 2023. With a price-to-sales ratio stretching above 30 in early November, the valuation has become a major point of debate.

The smart money is watching. While some selling can be chalked up to taking profits after such a run, the sheer scale and the specific players involved demand a closer look. When a billionaire like Englander, whose fund has outperformed the S&P 500 by 38 percentage points over three years, trims a core holding by a fifth, it raises a red flag. It suggests even the most bullish AI believers are weighing the risks of a stretched valuation against the potential for a bubble. This 13F snapshot is the first hard data point on what the institutional whales are doing as Nvidia prepares for its next earnings report.

The Skin in the Game Test: CEO and Insider Alignment

The smart money is selling. That's the headline from the 13F filings. But what about the people running the company? Do their actions align with the bullish narrative they are broadcasting?

The evidence here is a critical gap. The filings show what billionaires like Israel Englander and David Tepper did with their own money. They sold. But we have no data on what CEO Jensen Huang or other insiders are doing. The company's own statements, like the recent one from Huang touting breakthrough Blackwell NVL72 AI supercomputer and surging global demand, are pure hype. Without insider transaction data, we can't test the alignment of interest.

This creates a classic tension. When the CEO is pumping the stock from the stage, and the most sophisticated investors are quietly trimming their positions, it raises a red flag. It suggests the smart money may be seeing a valuation risk or a near-term headwind that isn't in the official script. The $4.5 billion inventory charge from last quarter is a reminder of execution risk, even for a leader. If the insiders were buying, it would signal they believe the current price is a buying opportunity despite the noise. Their silence speaks volumes.

The bottom line is that profit-taking is a plausible excuse for the selling. But when it's done by the funds that have been right for years, it's harder to dismiss. The lack of insider buying data means we can't confirm if the company's skin is still in the game. In a market where the smart money is moving, that absence of alignment is the most telling signal of all.

The Competitive Threat: When Customers Build Their Own Chips

The smart money is selling. The reasons are mounting. Beyond profit-taking and valuation concerns, there's a fundamental, structural threat that could erode Nvidia's long-term moat: its largest customers are building their own chips.

This is a critical shift. For years, Nvidia was the indispensable supplier, commanding premium prices for its compute superiority. Now, the dynamic is changing. As noted in the evidence, many of Nvidia's top customers by net sales are developing GPUs and AI solutions for internal data center use. This isn't a distant rumor; it's a direct attack on the scarcity that has fueled its pricing power and gross margins.

The implication is stark. When a customer like Meta Platforms or Amazon builds its own AI silicon, it transforms Nvidia from a pure-play supplier into a potential commoditized component. The company that once dictated terms is now facing the risk of becoming a vendor in its own ecosystem. This is a secular threat, not a quarterly headwind. It's the kind of structural erosion that institutional investors, like the billionaires trimming their positions, are forced to price in.

The smart money may be positioning ahead of this shift. While current earnings reports will likely show robust sales and profits, the 13F filings reveal a longer-term bet. These investors are not just reacting to a single quarter; they are hedging against a future where Nvidia's dominance is challenged from within. The multi-year partnership with Meta is a positive, but it's also a reminder that even the strongest alliances are temporary. When the customer can build its own, the supplier's leverage weakens.

This is the deeper signal beneath the profit-taking narrative. The smart money sees a company at the peak of its current cycle, facing a future where its core advantage is no longer a moat but a bridge that others can cross. That's a risk that isn't reflected in the next earnings call, but it's clearly in the filings.

The Bubble Watch: Valuation and Historical Precedent

The smart money is selling. The reasons are clear. The valuation is stretched to a level historically associated with market bubbles.

Nvidia's stock has rallied nearly 1,200% since the start of 2023. That run has pushed its price-to-sales ratio above 30 in early November. That number is the key metric. A P/S ratio north of 30 has often indicated the presence of a bubble in an underlying stock or a next-big-thing trend. This isn't just a high multiple; it's a valuation premium that leaves almost no room for error.

In practice, this means the stock is pricing in perfection. Any stumble-any sign of slowing growth, margin pressure, or the competitive threats we've discussed-could trigger a sharp re-rating. The market is paying for flawless execution for years to come. When you're trading at that level, even a slight miss on expectations can feel catastrophic.

That's the disciplined move behind the selling. These billionaire investors aren't just taking profits; they're locking in gains before a potential correction. They are watching the historical precedent and seeing the warning signs. The company may trounce Wall Street's expectations next week, but the 13F filings reveal a longer-term bet. These are the savviest money managers, and they are hedging against the risk that Nvidia's current dominance is a peak, not a plateau.

The bottom line is that the smart money sees a stock priced for a miracle. Their selling is a signal that the margin of safety has vanished. In a market where history often repeats, that's the most telling data point of all.

Catalysts and Risks: What to Watch on Earnings Day

The next move is set for Wednesday, February 25, 2026, after the market closes. This earnings report is the immediate catalyst that will either validate the bullish narrative or confirm the smart money's caution. The thesis from the 13F data and financials is clear: the stock is priced for perfection, facing structural threats and a stretched valuation. The report must show that reality matches the hype.

The key metrics to watch are twofold. First, management's guidance for future quarters. Given the institutional selling, investors will scrutinize any forward-looking statements for signs of slowing growth or margin pressure. Second, any update on China H20 sales is critical. The $4.5 billion inventory charge last quarter was a massive hit, but it was framed as a one-time cost tied to new export rules. If management provides details on when or if H20 demand will recover, it will signal whether that charge was a recurring theme or a singular event. Any hint of ongoing weakness in that market would directly contradict the CEO's talk of surging global demand.

The primary risk is that institutional selling accelerates post-earnings. The 13F filings show these savvy investors are already trimming. If the results, while strong, fail to exceed the already sky-high expectations baked into the stock, it could trigger a wave of profit-taking from other large holders. The smart money is watching the valuation and the competitive landscape. If the earnings call doesn't provide a compelling reason to ignore those risks, the stock could face significant downward pressure. The bottom line is that the market has already priced in a miracle. The report must deliver one to hold.
