Nvidia's Board Probe Validated a Short Seller's 40-Page Warning

On November 9, 2026, Nvidia (NASDAQ:NVDA) closed down 4.27% at $178.67, wiping the chipmaker's market value down to $4.31 trillion — and validating a short seller that Wall Street had spent six months ignoring. Culper Research, a New York short seller, had published a 40-page report on May 13, 2026, alleging that CEO Jensen Huang was "uncomfortably close" to Alice Huang, an executive at the Singapore chip buyer Megaspeed. Culper disclosed a short position in the report, meaning it profits when the stock falls.

On November 8, Huang admitted in a staff memo that he had been unfaithful to his wife. Nvidia's board opened an independent investigation. The stock's fall to $178.67 the next day left it 20.9% below its May 13 close, though shares traded at $180.50 after hours. The story matters well beyond one CEO's personal conduct, because Culper's report did not stop at the relationship. It tracked money and chips through Megaspeed, which Culper called Nvidia's largest Southeast Asian buyer, and raised questions that go to the core of a $4 trillion company's revenue.

What did Culper allege in May?

The report made several specific claims. Culper alleged that Huang had been seen partying and socializing with Alice Huang, who has no relation to the CEO, on several occasions. It said some Nvidia employees questioned whether the two had a special relationship.

The financial allegations were heavier. Culper alleged that more than 20% of Nvidia's fiscal 2026 compute revenue was still driven by Chinese demand, flowing through illegal diversion and Southeast Asian intermediaries. That claim directly contradicted Nvidia's own account. The company had said its China compute business went to zero after the April 2025 export restrictions took effect.

Culper also alleged that Alibaba (NYSE:BABA) secretly financed Megaspeed through shell companies. The numbers in the report were striking:

• Megaspeed's balance sheet grew from $33 million at the end of 2023 to roughly $3 billion a year later.
• Most of that increase came from $2.9 billion in refundable deposits from unknown sources.
• More than 20% of fiscal 2026 compute revenue allegedly traced back to Chinese demand.

Why did investors ignore the report?

The market's response in May was a shrug — and then a rally. Shares rose 2.29% to $225.83 on May 13, the day the report dropped. They gained another 4.39% to $235.74 the next day. By October 6, Nvidia set a record close of $239.24.

There were reasons for the indifference. Markets tend to discount short reports on very large companies because the author profits from a decline and the claims are hard to verify independently. Growth also outweighed the allegations: second-quarter revenue rose 105.85% from a year earlier. When a company is compounding at that pace, a short seller's 40 pages of accusations struggle to get traction.

One caveat deserves emphasis. The drop from October's record includes the November 5 AI-chip selloff. Culper's report did not single-handedly take Nvidia down 20.9% from its May close. Broad AI-sector weakness played a part, and the November admissions landed on top of it.

Which claims now have outside support?

Since May, some of Culper's allegations have picked up partial corroboration. On November 9, documents were reported to show that Alibaba lent money to Megaspeed through subsidiaries — the first outside support for the shell-company financing claim.

On October 29, U.S. officials were reported to have concluded that Alice Huang was a Chinese intelligence asset. That finding is unproven, and China's Foreign Ministry calls it unsupported. It remains one of the most explosive claims in the affair, and one of the least settled.

Other allegations remain unverified:

• The claim that more than 20% of fiscal 2026 compute revenue came from Chinese demand.
• The allegation that Megaspeed's subsidiary Speedmatrix imported $4.6 billion of goods, about $4 billion of it from Nvidia partner Aivres Systems.

Nvidia's only defense on record dates to October 29, when a spokesperson said the diversion claims had been looked into and debunked the year before. The company has not publicly addressed the Megaspeed financing or the intelligence-asset reporting.

Why does diversion matter more than the memo?

The board investigation into Huang's conduct makes headlines. The diversion allegation moves markets. If the illegal China-driven demand is real, Nvidia faces export-control, legal, and revenue-quality risk all at once. Data Center revenue was $89.023 billion last quarter. An allegation touching more than 20% of compute revenue goes straight at the segment that powers the entire business.

If Culper is wrong on diversion, the probe is mainly a governance and key-person problem. That is serious for a company so identified with one CEO. But the business can absorb it while guiding to $108.0 billion in quarterly revenue — a figure that, notably, excludes any China data center compute revenue.

That distinction is the crux for investors. A scandal about a CEO's personal life is survivable at Nvidia's scale. A finding that billions in revenue rest on illegally diverted chips to China would invite enforcement action and force a rethink of what Nvidia's growth is actually built on.

What should investors watch before November 17?

Nvidia's business still appears intact despite the board investigation, though the probe's outcome remains uncertain. The next test arrives November 17, when the earnings report is expected.

Management has a track record of silence here. It did not mention Culper or Alice Huang on the August call. That avoidance gets harder to sustain now. Investors will be looking for the company to address three things: China exposure, its Southeast Asian customers, and the investigation's scope.

For investors who want AI chip exposure with less reliance on a single CEO, the VanEck Semiconductor ETF (NASDAQ:SMH) holds Nvidia alongside a basket of other chipmakers. It is one way to keep the sector bet while diluting the key-person risk.

Two signals would mark a real deterioration in the outlook. The first is technical: a close below $178.67 after the November 17 report would break the post-scandal floor. The second is legal: a filing showing the board's investigation covers Megaspeed or export compliance would signal the probe has moved beyond Huang's personal conduct and into the revenue itself — the scenario Culper was shorting for all along.
