The poll is scheduled to close around 11.20am on Monday – although the billionaire did not give details on when he would step down if the poll results said he should.

Replying to a user on Twitter later, Musk said that “There is no successor” in reference to a possible change in CEO.

Musk told a Delaware court last month that he would reduce his time at Twitter and eventually find a new leader to run the company.

The poll comes after Twitter’s Sunday policy update, which prohibited accounts created solely for the purpose of promoting other social media firms and content containing links or usernames for rival platforms.

Minutes before the poll, Musk apologised and tweeted: “Going forward, there will be a vote for major policy changes.”

The policy update will impact content from social media platforms like Meta Platforms’ Facebook and Instagram, along with Mastodon, Truth Social, Tribel, Nostr, and Post while allowing cross-content posting, Twitter support said in a tweet.

Former Twitter CEO Jack Dorsey, who recently invested in social media platform Nostr, replied to the Twitter support post with one word: “Why?”

In a reply to another user posting about the Nostr promotion ban, Dorsey said, “doesn’t make sense.”

Short video platform TikTok, owned by China’s ByteDance, was not included in the list.
