The US chipmaker, Nvidia, has announced an independent investigation into the extramarital affair of its CEO, Jensen Huang, with a woman alleged to be a Chinese spy. This revelation led to a significant 6% drop in the company's share price, resulting in a loss of approximately $250 billion from Nvidia's market value on Monday. The investigation comes after reports of US intelligence officials believing that Alice Huang, also known as Huang Le, was a spy for Beijing. China has denied these claims, while US President Donald Trump has expressed support for Huang. However, the news has sparked concerns about Nvidia's national security and has prompted calls for a closed-door briefing by several Congressional committees. Despite the ongoing investigation and potential risks to the company, analysts believe that the impact on Nvidia will be short-lived due to its central role in the AI industry. The concerns now focus on what would happen to Nvidia if Huang were removed from his position, as he is not considered to have a clear successor. This investigation marks a significant challenge for one of the world's most valuable tech companies and could have far-reaching implications for US-China relations in the AI sector.
