Elon Musk sells $3.58B worth of Tesla stock

Elon Musk sold another USD 3.58 billion worth of Tesla stock this week, but it wasn't clear where the proceeds were being spent.

The Tesla CEO, and new owner of Twitter, sold the shares from Monday through Wednesday, according to a filing posted Wednesday night by the US Securities and Exchange Commission.

Musk has sold nearly USD 23 billion worth of Tesla stock since April, with much of the money likely going to help fund his USD 44 billion acquisition of Twitter.

The sale comes as shares of the electric vehicle and solar panel maker have collapsed, losing over half their value since Musk first disclosed in April that he was buying up Twitter stock.

The falling shares have bumped Musk from his status as the world's wealthiest person, with his net worth falling to USD 174 billion, according to Forbes.

He was passed last week by French fashion and cosmetics magnate Bernard Arnault.

The takeover of Twitter has not been smooth, and some big companies have halted advertising on the social media platform.

Musk has said that Twitter had "a massive drop in revenue" due to the advertiser losses.

Tesla stock has recently suffered as Musk has spent much of his time running Twitter, raising concerns that he has become distracted from the car company.

Wedbush analyst Dan Ives said Musk is now a villain in the eyes of Tesla investors. He said Tesla's fundamentals remain healthy but his behaviour with Twitter is hurting the company's brand.

"The Twitter overhang is a nightmare that is growing with no one but Musk to blame," Ives wrote in an email.

A message was left with Tesla on Wednesday night seeking comment on the stock sale.
