Musk’s tweet offering guidance on timing for an anticipated increase in Tesla’s market cap has since been deleted, but screenshots were widely shared on Twitter.
The U.S. Securities and Exchange Commission has clashed with Musk and Tesla over the CEO’s unfettered use of Twitter before.
In the third quarter of 2018, Musk faced securities fraud charges from the SEC after he tweeted to his tens of millions of followers then that he was planning to take Tesla private at $420 a share, and had secured funding to do so. Tesla’s stock price jumped more than 6 percent that day.
