Investors have urged Musk to step down as Twitter CEO and punished Tesla stock, which is down nearly 60% this year and hit a fresh two-year low on Monday.
On a Twitter poll from Musk on Sunday asking whether he should step down as Twitter CEO, 57.5% of 17.5 million people voted "yes."
Ross Gerber, CEO of Gerber Kawasaki Wealth & Investment Management and a big Tesla bull, said last week that he would run for Tesla board and had notified Tesla.
Leo KoGuan, a major individual Tesla shareholder, wrote on Twitter earlier that Musk had "abandoned Tesla and Tesla has no working CEO."
"The whole situation is just weird, and weird is being kind," said Matthew Tuttle, CEO of Tuttle Capital Management.
