Singapore authorities are investigating artificial intelligence computing firm Megaspeed, a customer of American AI chipmaker Nvidia , for allegedly helping Chinese companies evade curbs on U.S. chip exports. "The Singapore Police Force confirms that investigations are ongoing into Megaspeed for suspected breaches of our domestic laws," the police told CNBC in an email. The probe comes as the New York Times reported Thursday that the U.S. Commerce Department was also investigating whether Megaspeed skirted American export controls, citing anonymous officials and other people familiar with the matter. The twin investigations into Megaspeed could raise questions about Nvidia's ability to track its chip exports effectively and to comply with U.S. restrictions on the sale of its most advanced AI chips to China. According to an Nvidia spokesperson, the company had engaged the U.S. government on the matter and performed its own inquiry, without identifying "any reason to believe products have been diverted." "NVIDIA visited multiple Megaspeed sites yet again earlier this week and confirmed what we previously observed—Megaspeed is running a small commercial cloud, like many other companies throughout the world, as allowed by U.S. export control rules," they said in a statement shared with CNBC Friday. Megaspeed didn't immediately respond to a request for comment, nor did the U.S. Commerce Department. The Times reported that Megaspeed, which spun off from a Chinese gaming company in 2023, bought nearly $2 billion worth of Nvidia's most advanced products through its subsidiary in Malaysia.
