Nvidia’s China Problem Returns to Haunt the Chipmaker as Short Seller’s Warning Resurfaces

Nvidia, a major player in the artificial intelligence (AI) chip market, is currently grappling with a dual crisis. The company's founder and CEO, Jensen Huang, has admitted to an extramarital affair, a fact that surfaced in an internal memo. This issue, which has been under an independent investigation by Nvidia's board, was compounded by allegations that Huang may have been a target of a foreign intelligence operation.

The board maintains that there is no evidence of national security or company secrets being compromised, but the situation has cast a shadow over the tech giant.

Adding to the complexity of the situation is a report titled "Nvidia: The China Problem," published by short-selling research firm Culper Research on May 13. The report highlighted Nvidia's significant exposure to the Chinese market, with more than 20% of the company's fiscal 2026 computing revenue estimated to be tied to China.

Culper pointed to Megaspeed, a Singapore-based semiconductor procurement firm, as a significant channel for bypassing U.S. export controls. The report alleged that Megaspeed had received funding from China's Alibaba and that a substantial portion of these funds had been directed to subsidiaries, including Malaysian-based Speedmatrix.

The report also raised questions about the relationship between Huang and Alice Huang, a former senior executive at Megaspeed. The two were reportedly close, with evidence of their interactions extending to Taiwan in June 2024 and a restaurant in Taiwan in May 2025. While Huang initially dismissed these interactions as business-related, recent reports have suggested that U.S. intelligence authorities suspect Alice Huang of having ties to China's Ministry of State Security.

Huang has since acknowledged being unfaithful to his wife, though he has not named the individual involved.

These developments have raised concerns among analysts, who warn that prolonged uncertainty over Huang's future could potentially destabilize Nvidia's management. With no publicly identified successor, Huang's departure could disrupt investment decisions and product launches, with potential repercussions for the broader AI ecosystem.

The controversy could also affect Nvidia's business in China, given the company's advocacy for easing semiconductor export restrictions on the country. The latest allegations could lead to closer regulatory scrutiny, further complicating Nvidia's operations in the region.

Since the disclosure of Culper's short position, Nvidia shares have experienced a drop of about 20%, while the S&P 500 has gained around 2% over the same period. However, the extent to which the report's claims have validated or that Culper has made a profit remains unclear, as the firm's investment details in the short position have not been disclosed. The situation underscores the delicate balance Nvidia must navigate as it deals with internal issues and external market pressures.
