A report said U.S. AI chipmaker Nvidia is preparing to dismiss its founder and CEO Jensen Huang (황). As a controversy over an extramarital relationship spread into suspicions of Chinese intelligence gathering, Huang's future became uncertain after 33 years leading the company.

On Tuesday, the Wall Street Journal (WSJ), citing multiple sources, reported that Nvidia's board is preparing to replace Huang. It said the board could hold a meeting as early as that day to discuss his future.

According to the WSJ, Huang had 2 extramarital relationships. One of the women was Alice Huang, who is suspected of being linked to Chinese intelligence agencies. No official announcement has been made that his dismissal has been finally decided.

The controversy surrounding Huang is widening, however. The New York Times (NYT) also reported that Huang had an extramarital relationship with a female Nvidia executive who reports to him.

The FBI is also looking into the matter. In Congress, concerns were raised about Nvidia's semiconductor exports to China and national security. After the WSJ report, Nvidia shares fell about 8 percent in after-hours trading.

Nvidia has not yet announced an official position on whether it will dismiss Huang or select a successor. The direction of the situation depends on the results of the board's investigation and the final personnel decision.
