Here’s a related question… Why is Elon Musk demanding a massive cash salary from the board rather than typical CEO compensation of stock and performance bonuses?

Likely, he understands that the company is massively overvalued due to his hype machine. He is cashing out before it fails.

As a plus, by manufacturing animosity between himself and the board, he is preloading the ammunition for when the company fails and discards him. When he leaves, the hype machine leaves with him. The stock will “crash” which really means returning to a sane market valuation. He can easily claim that the failure was due to the board interfering with his genius. The board members either know this, or are his lackies (or both). They will ride the wave along with him as long as they can.

In essence, we are witnessing the largest pump and dump scheme in history, and it is being done in the open.
