Nvidia faces scrutiny over China revenue exposure amid spy concerns

Wall Street is quietly running a new kind of stress test on Nvidia. The question is no longer about demand. It is about how much of the business could be exposed if Washington decides to look harder at where its chips end up.

The trigger is a story that sounds more like a streaming thriller than an earnings call. US intelligence has assessed that a former executive at a Singapore data center firm, who reportedly had a close romantic relationship with CEO Jensen Huang, was a Chinese intelligence asset.

The numbers behind the nervousness

On Monday, New Street Research put a figure on the risk. Its analysis estimates that as much as 10% of Nvidia’s revenues may come directly or indirectly from China.

In dollar terms, New Street pegs that at between $37 and $47 billion. The research firm measured that against consensus estimates it cited for Nvidia’s total expected fiscal year 2027 revenue of $411 billion.

That range matters because of the word “indirectly.” Direct China sales are relatively easy to count, while chips flowing through third-party buyers in other countries are much harder to trace.

For comparison, China accounted for roughly 9% of Nvidia’s total revenue in fiscal 2026. That was down from about 19% the year before.

The Megaspeed connection

At the center of the story is Alice Huang, a former senior executive at Megaspeed, a data center company based in Singapore. US intelligence has assessed that she was a Chinese intelligence asset linked to Beijing’s Ministry of State Security.

She is accused of passing information to Beijing and helping facilitate access to restricted Nvidia chips. The New York Times reported the intelligence assessment in late October 2026.

The commercial backdrop is what turns personal scandal into a corporate problem. Megaspeed has bought nearly $5 billion in Nvidia AI chips over the last few years.

The firm has also faced ongoing scrutiny over its dealings, including allegations that it sought to get around US export rules.

Nvidia’s board responded on November 8, 2026, by launching an independent investigation. The probe is examining whether Jensen Huang was the target of a foreign intelligence operation.

The same day, Huang publicly apologized for being unfaithful to his wife and pledged to cooperate.

Investors reacted about how you would expect. Nvidia shares fell as much as 8% before partially recovering.

Why export controls make this so sensitive

The US began imposing strict export controls on advanced AI chips in 2022. The goal was to keep the most powerful processors out of Chinese hands, and those rules have sharply reduced Nvidia’s exposure to the Chinese market.

Complying has not been cheap. Nvidia has taken substantial inventory charges tied to alternative chip versions it designed specifically for Chinese customers.

The revenue decline from about 19% to roughly 9% is the visible result of that squeeze.

The Megaspeed allegations raise a different and arguably more uncomfortable question. Export controls only work if chips sold to approved buyers stay with approved buyers.

If restricted hardware was diverted to China through an intermediary, it would suggest the controls leaked. It would also put pressure on how closely chipmakers vet the customers buying their most advanced products.

What this means for Nvidia and its investors

The immediate market concern is not that Nvidia’s China revenue disappears overnight. New Street’s estimate frames the exposure as a slice of the business, meaningful but not dominant against a projected $411 billion top line.

The bigger risk is regulatory. Concerns about a potential crackdown on Nvidia’s operations are circulating on Wall Street, and the board investigation’s findings could shape how aggressively Washington responds.

That is why the gap between “directly” and “indirectly” in New Street’s analysis deserves attention. If regulators decide to tighten scrutiny on intermediaries in places like Singapore, revenue that never shows up on a China line item could still be at risk.

The 8% intraday drop followed by a partial rebound tells its own story.

For now, the key items on the watch list are straightforward. Those include the outcome of the board’s independent probe, any regulatory response to the Megaspeed relationship, and whether Nvidia offers more detail on how it tracks where its chips ultimately end up.
