A short seller who flagged Nvidia’s China exposure months before it became public says the problem extends beyond a single company. Christian Lamarco, founder of Culper Research, claims Megaspeed is not the only firm helping China access chips.
Lamarco said his firm stood by its findings despite the scrutiny that followed. “We were confident in the research initially, and we’re still confident in it now,” he said.
Culper Research published its concerns well before the issue drew wider attention. The firm’s early warning put it ahead of larger investors and analysts tracking Nvidia’s China business.
The dispute centers on how advanced chips reach China despite export controls. Third-party intermediaries can obscure the final destination of hardware, making enforcement difficult.
Megaspeed has been named as one such pathway. Lamarco argues that focusing on one company misses the broader pattern.
Nvidia has not commented publicly on the specific allegations. The company has previously said it complies with export rules.
Regulators continue to examine how restricted technology moves across borders. The case highlights the challenge of policing global chip supply chains.
Culper’s claims remain unproven in court. Still, the research adds pressure on Nvidia and its partners to explain their China dealings.
