A suspected “female spy” affair has once again put Jensen Huang, chief executive of US chip giant Nvidia, in the spotlight.

Last Thursday (29 October), The New York Times published a report titled “Nvidia Chief Seen as Target of Chinese Spy Plot”. With a hint of gossip, it “exposed” the tech heavyweight’s relationship with a Chinese woman named Alice Huang, also known as Huang Le.

According to the report, US intelligence agencies believe Huang Le, who previously worked for data company Megaspeed, is an intelligence operative passing information to Beijing. While monitoring her, the authorities discovered that she had close ties with Jensen Huang.

This put the US authorities on greater alert. Nvidia, which Jensen Huang heads, is a pivotal company in US artificial intelligence (AI) and has a major influence on the country’s technological development. US officials suspect that the woman may have been using her close ties with Huang to gather internal information about Nvidia. More worrying for the US authorities is that Jensen Huang is a favourite of President Donald Trump. Not only does he understand Trump’s thinking on key issues such as US-China technological competition, he may even influence some of Washington’s policies towards China.

Who exactly is this mysterious woman said to be close to Huang? There is little public information about Huang Le. She reportedly worked in the Chinese media, as well as at banks and securities firms, but these details are difficult to verify independently.

Megaspeed, where Huang Le worked in recent years, has drawn particular scrutiny from the US authorities amid the US-China tech war. In recent years, the US has strictly restricted exports of advanced chips and semiconductor manufacturing equipment to China and cracked down on the chip “black market”. It has also investigated Chinese companies that circumvent US export restrictions by buying cloud services overseas and training models at data centres outside China. Megaspeed, a Singapore-headquartered company in the data centre and cloud computing business, is one of those under investigation.

Citing data from trade data platform ImportGenius, The New York Times reported that, between June 2024 and February this year, the little-known company purchased at least US$4.8 billion (S$6.1 billion) worth of advanced AI equipment containing Nvidia chips and technology through an affiliated company in Malaysia.

As for the interactions between Jensen Huang and Huang Le, the report detailed only two occasions. In June 2024, Huang was drinking with a group of technology executives at a bar in Taipei. A photograph taken then and posted on professional networking platform LinkedIn shows Huang Le sitting beside him. In May 2025, again in Taipei, Jensen Huang spoke to the media outside a restaurant after a business dinner. Huang Le was standing a short distance behind him at the restaurant’s entrance.

The New York Times report pieced together a suggestive picture, but many questions about the suspected “female spy” affair involving Jensen Huang remain unanswered. Apart from appearing together on those two occasions in Taipei and having routine business dealings, did Jensen Huang and Huang Le have any other, closer interactions or contact? When did Huang Le, the suspected intelligence operative, begin gathering information for Beijing, and what information did she pass on? None of this is known.

But even if the suspicions ultimately prove unfounded, one reality is hard to ignore: US-China technological competition is increasingly being framed in national security terms, and a “technological iron curtain” is descending. Espionage is now imagined to extend beyond stealing military and defence secrets or government documents. The boundaries between national security intelligence and commercial intelligence are blurring. Technology industry strategies, technological pathways, business decisions and even lobbying efforts by executives of pivotal companies may all become information that intelligence agencies strive to obtain — and potential leaks that national security agencies carefully guard against.

After The New York Times report was published, Jensen Huang denied the allegations, stressing that his contact with Huang Le was no different from his interactions with other Chinese customers and executives. Their relationship and contact were all connected to Megaspeed, and “it was all completely normal and not unusual”. He also said Nvidia had conducted a comprehensive audit of the graphics processing units (GPUs) delivered to Megaspeed, accounting for the deployment of every chip to ensure that none had been illegally re-exported to China.

However, the impact of espionage allegations extends beyond whether the individuals or companies concerned are implicated. Such allegations can also become tools for shaping narratives in the tech war, influencing public opinion, redrawing the boundaries of commercial trust and changing corporate decisions.

Shortly after the espionage controversy erupted, the Financial Times reported on Tuesday (3 November), citing sources, that Nvidia was asking its data centre partners to reduce their exposure to Chinese customers and ensure that at least 51% of their services were sold to companies outside China. In other words, Nvidia is further restricting Chinese companies’ access to its computing power through cloud services rented from data centres in places such as Southeast Asia. The move is also believed to be aimed at reducing the risks arising from US official investigations.

From Nvidia’s dramatic ups and downs in the Chinese market amid the US-China technological rivalry to Huang’s latest involvement in the “female spy” controversy, it is clear that Nvidia has long ceased to be merely a technology company.

With its critical technology and vast capital, it is a strategic US asset, with a bearing on whether the country can maintain its lead in technological competition. Jensen Huang, too, has long ceased to be simply a businessman. His close relationship with Trump gives him political clout that few entrepreneurs can match.

But as national security and commercial interests become increasingly intertwined in complex and potentially conflicting ways, this heavyweight who straddles technology, business and politics will face ever closer scrutiny — even if he has not been targeted for cultivation.
