Nvidia’s board is preparing to remove Jensen Huang as CEO, according to The Wall Street Journal.
Huang co-founded the company in 1993.
He has run it every day since.
The Journal, citing people familiar with the matter, says the board planned to meet as soon as Wednesday to decide his future.
No decision has been announced.
Just three days earlier, the same board said it had confidence in him and his leadership team.
That was Sunday, the day Huang emailed employees and admitted he had been unfaithful to his wife.
Reports tied that affair to Alice Huang, a businesswoman U.S. intelligence believes was working for China, which Beijing denies.
Then on Wednesday, The New York Times reported a second relationship, with Kimberly Powell, an Nvidia vice president who reports directly to him.
Huang has not confirmed that one.
The board has already hired the law firm Wachtell, Lipton, Rosen & Katz to investigate, and the Journal says directors may act before that review is finished.
Nvidia shares fell as much as 8% after hours on the news.
The company reports earnings on November 17, and no successor has been named.
