Tesla investors are concerned that Musk is spreading himself too thin after the Twitter deal.
Tesla has already lost nearly 60% of its value this year as, like other carmakers, it grapples with supply chain issues and increasing competition in the EV space.
Last month, Musk told a Delaware court that he would reduce his time at Twitter and eventually find a new leader to run the social media company.
“There is no successor,” Musk said on Sunday, responding to a Twitter user’s comment on a possible change in CEO.
The poll comes after Twitter’s Sunday policy update, which bans accounts created for the purpose of promoting other social media firms and content that contains links or usernames for rival platforms.
