Short seller flagged Nvidia CEO's China-linked contact six months early

Six months before Nvidia opened a formal investigation into its own CEO, a New York short seller had already flagged the risk in print. Culper Research's May 13 report on Megaspeed — a Singapore-based Nvidia chip buyer — described the relationship between Jensen Huang and Megaspeed executive Alice Huang as "uncomfortably close." Alice Huang, who shares the CEO's surname but is not related, is now suspected by U.S. intelligence officials of being a Chinese spy.

Jensen Huang admitted to an extramarital affair over the weekend, and Nvidia has launched a formal probe into the relationship. That admission came roughly half a year after Culper put its allegations on the public record. The report was posted to X in May and remains available on the web.

What did the short seller actually allege?

Culper's report emerged from an investigation into Megaspeed's ties to Nvidia, not from any surveillance tip. It noted that the Nvidia CEO was spotted partying and socializing with Alice Huang on multiple occasions. The report claimed some Nvidia employees had privately wondered whether the two had a "special relationship." At the time, that phrasing read as innuendo. Today it reads as an early warning that nobody in the vendor's governance chain acted on — at least not publicly.

The report went further on money flows. Culper theorized that Nvidia's China business, lost to U.S. export controls, had been rerouted through Southeast Asia. It named Megaspeed, a major chip buyer in the region, as a suspected conduit. It also alleged that Chinese tech giant Alibaba secretly financed Megaspeed through shell companies. Neither allegation has been independently verified. Treat both as thesis, not fact.

What do the numbers show?

The financial record is the hardest evidence in the file. Culper pointed to figures showing Megaspeed's total liabilities and equity grew from $33 million at the end of 2023 to roughly $3 billion by the end of 2024 — a roughly ninetyfold expansion inside twelve months. Much of that growth came as refundable deposits from an unidentified source. A buyer that balloons from $33 million to $3 billion in one year, funded by parties it will not name, is either the fastest-growing middleman in Asia or something else entirely. The short seller argued for the latter.

The Financial Times reported Monday that documents show Alibaba lent money to Megaspeed through subsidiaries. That reporting lends partial support to Culper's financing claim, though it does not by itself prove chip diversion.

Why does the espionage angle matter for buyers?

U.S. intelligence officials believe the Chinese government recruited Alice Huang to collect intelligence on Jensen Huang and influence his position on U.S. export controls for advanced AI chips. That detail transforms the story from a personnel scandal into a supply-chain and policy exposure. If a foreign state targeted the CEO of the dominant AI accelerator vendor, the same playbook presumably works on procurement leads and infrastructure executives further down the chain. Export-control enforcement, chip allocation and vendor relationships all sit downstream of decisions made at this level.

For enterprises budgeting GPU capacity, the Megaspeed question cuts both ways. If restricted chips genuinely moved through Southeast Asian channels, enforcement could tighten and gray-market supply could dry up. If the diversion theory collapses, the May report becomes a footnote. There is no verified figure yet for how many units, if any, moved through Megaspeed.

Who benefits from these claims?

Here is the caveat that must follow every promise in this story. Culper Research is a short seller. It stood to financially benefit from making these allegations, and it published them while positioned to profit if Nvidia's stock fell. That does not make the claims false — the affair admission and the FT's Alibaba lending documentation have both since landed in Culper's favor — but it means the report was never a neutral audit. The suspected illegal chip diversion remains unverified by any regulator or independent body named in the record.

Nvidia has not publicly detailed the scope or timeline of its formal investigation. The company has not said whether its board reviewed the May report when it surfaced. It has not said whether Megaspeed remains a customer. Those silences are the story now. A $3-trillion-class chip vendor with a compromised CEO is a governance event; the market has only begun to price how much of one.
