Elon Musk, during an event at SpaceX headquarters in Hawthorne, California, U.S., on Thursday, Oct. 10, 2019.
In a follow-up tweet around two hours later, Musk added that he was “still committed to the acquisition.”
Twitter’s stock plummeted 18% in premarket trading following the initial announcement, but trimmed some losses after the second tweet. Shares were down about 10% after markets opened. A spokesperson for the social media company did not immediately respond to a CNBC request for comment.
Even before Friday’s announcement, the company’s market value had fallen to $9 billion beneath the offer price due to concerns about the deal.
Twitter estimated in a filing earlier this month that fewer than 5% of its monetizable daily active users during the first quarter were bots or spam accounts.
Musk, who is the world’s richest person on paper, now wants the company to confirm this before he continues with the deal, which is being partly funded by Oracle co-founder Larry Ellison and venture capital firm Andreessen Horowitz.
The San Francisco-headquartered social media company said in the filing that it had 229 million users in the first quarter who were served advertising.
“Permanent bans should be extremely rare and really reserved for accounts that are bots, or scam, spam accounts … I do think it was not correct to ban Donald Trump,” Musk said at FT Live’s Future of the Car conference. “I think that was a mistake, because it alienated a large part of the country and did not ultimately result in Donald Trump not having a voice.”
Earlier this month, Bill Gates warned that Musk could make Twitter “worse.” Speaking at The Wall Street Journal’s CEO Summit, Gates said it’s unclear how Musk will change Twitter if he takes ownership, while also raising concerns about the spread of misinformation on social media platforms.
Gates went on to question what Musk’s goal is with Twitter and whether his drive to promote free speech is sensible. “What are his goals for what it ends up being? Does that match this idea of less extreme falsehoods spreading so quickly [and] weird conspiracy theories? Does he share that goal or not?” Gates said.
Before Musk made his bid to buy Twitter outright, he failed to disclose a more than 9% stake in the company within the SEC’s mandatory 10-day window.
The Information reported that the Federal Trade Commission is probing the timing of Musk’s disclosure. Bloomberg later said the FTC is separately reviewing the acquisition itself, though many experts don’t expect the deal to raise antitrust concerns.
The FTC doesn’t disclose ongoing investigations, and an FTC spokesperson declined to comment.
Tesla’s share price climbed nearly 7% in premarket trading Friday.
Susannah Streeter, senior investment and markets analyst at Hargreaves Lansdown, said some are likely to query whether fake accounts are the real reason behind this delaying tactic.
“The $44 billion price tag is huge, and it may be a strategy to row back on the amount he is prepared to pay to acquire the platform,” she said in a statement.
