Nvidia's shares have sunk 8.81% this Monday on Wall Street against cases of fraud in the sale of chips from Singapore, after country sources confirmed that the products involved probably belong to the American manufacturer. The case dates back to last week, when the Singapore authorities reported the arrest of three people, as part of a broader investigation, for selling chips to Chinawith the aim of evading the controls that the United States performs on the export of semiconductors to the Asian giant. Local media at first said The chips involved could be those of NVIDIA that the Deepseek China startup used to develop the artificial intelligence model (AI) that shook the markets weeks ago. The country's interior affairs minister has confirmed suspicions on Monday. «We evaluate that servers can contain Nvidia chips. If Malaysia was the final destination … we do not know with certainty at this time, «said the Minister of Interior Affairs and Law of Singapore, K. Shanmugam, in statements collected by 'CNBC'. Shanmugam has also assured that They have contacted the United States authorities To determine if the elements involved in the case are subject to the commercial restrictions imposed, with the aim of working together to avoid new cases of fraud in the future. While, USA has started research on Depseek To establish if the Chinese firm has used chips whose export to China is prohibited, among which are some of the components that NVIDIA elaborates. Given this situation, The Trump administration is valuing the possibility of hardening the conditions of sale of Nvidia chips to the Asian giant. In the White House, discussions are focused on the possibility of expanding restrictions to cover NVIDIA H20 chips. It should be noted that this product, which can be used to develop and execute artificial intelligence software and services, is smaller scale and is designed to comply with existing restrictions in the United States on shipments to China.
