Nvidia just showed what key-person risk looks like at $4 trillion

On Sunday Nvidia's board said it is opening an independent investigation after press reports that Jensen Huang had been the target of a foreign intelligence effort. A committee of independent directors with outside counsel will run it. The board said it has "no reason to believe" national security or company secrets were compromised.

In an email to staff, Huang admitted he had been unfaithful to his wife and said he takes full responsibility. He said he fully supports the review. He stays CEO, and the board says it has confidence in him.

I am not going to guess how the investigation ends. Nobody outside that room knows. What interests me as an investor is something else.

For thirty years Nvidia has been Jensen. The leather jacket, the keynotes, the bets on AI years before anyone else. That is a big part of why the stock earned its premium. It is also the risk nobody puts in a spreadsheet: what happens to the company when the person is the story, for the wrong reasons.

To be fair, the board did the textbook things fast. Independent directors, outside counsel, a clear statement, a CEO who says he will cooperate. That is what good governance looks like on a bad weekend.

But here is the lesson for the rest of us, and it is not only for trillion-dollar companies.

If you run a business of ten people and everything goes through you, you have the same risk. Your clients buy you. Your team waits for you. Your bank trusts you.

Ask yourself three questions this week:

• If I disappeared for a month, who signs, who sells, who decides?
• Would my best client stay if I was not on the call?
• Does anyone else know the passwords, the suppliers and the numbers?

Nvidia has a board, lawyers and a few trillion dollars to get through this. Most founders have none of that. Build the cover before you need it.
