Ask what Korea is talking about.

Nvidia CEO Jensen Huang has admitted to an extramarital affair with Alice Huang, a businesswoman suspected of working as a spy for the Chinese government, prompting a board probe into whether he was targeted by foreign intelligence, KBS World reports. The controversy has erased about $430 billion in Nvidia's market value over two sessions, and a shareholder has sued Nvidia and Huang, accusing them of deceiving investors, the Korea Times reports. U.S. officials allege Alice Huang passed information to Beijing, and Taiwan's immigration agency said she entered the island on a Hong Kong passport, according to the Korea Times. Korean industry officials worry the scandal could affect U.S. AI chip supply and Nvidia's partnerships in Korea, with Business Korea noting adverse effects are reaching U.S. tech curbs on China. Korean media have also resurfaced Huang's past TV comments about his wife, drawing renewed attention amid the affair admission, the Korea Times reports.
