Tesla Inc. Chief Executive Officer Elon Musk unloaded $5 billion of stock in the electric car-maker, shortly after holding a poll on Twitter over whether he should sell 10% of his massive stake in the company.
The world's richest person so far has disposed of more than 4.5 million shares this week, according to regulatory filings Wednesday. Those were his first sales in more than five years.
Musk, who frequently posts on Twitter and often engages on controversial topics, created a firestorm over the weekend with the survey about whether he should sell part of his Tesla stake - which he connected back to a debate about whether the ultra-wealthy are paying their fair share of taxes. The poll, which resulted in a decisive vote for him to sell, sent shares of the carmaker down 16% in two days as investors worried about the consequences of unloading such a big block of stock.
On Monday, Musk offloaded about $1.1 billion worth of stock to pay income taxes on equity options that he also exercised that day, two of the filings showed. Those transactions were made based on a pre-arranged trading plan adopted in mid-September.
On Tuesday and Wednesday, he carried out the remaining sales. The filings detailing those disposals didn't indicate that they were pre-planned.
The documents shed no light on whether Musk's weekend Twitter poll had any bearing on his decision to carry out some or all of the transactions - or whether he'll keep selling until he's met the 10% threshold. To get there, he'd have to get rid of roughly 17 million shares, and even more if he also includes exercisable options in his total holdings.
The options Musk exercised came from a big award he received in 2012. He would have had to exercise them before next August or they'd expire. Taxes on such transactions are usually covered by immediately disposing of some of the newly acquired shares. Earlier this year, Musk said publicly that he likely would exercise options earned from the 2012 award in the near future.
It's possible that the option exercises and related sales would have been executed regardless of the Twitter poll's outcome, given that they were made under a pre-arranged plan. But the terms of such plans aren't subject to public disclosure, and executives have wide latitude to cancel or modify them at any time.
Still, the headline-grabbing Twitter referendum pummeled Tesla's shares on Monday and Tuesday, wiping out $50 billion from Musk's net worth. Tesla rose 4.3% on Wednesday to close at $1,067.95, paring losses this week to less than 13%.
After the first few trades were disclosed, the stock rose 2.7% in post-market trading. Many of the filings came in after that ended, but Tesla tokens on the FTX crypto exchange were down to around $1,049 as of 2:06 p.m. in Hong Kong on Thursday.
The billionaire last sold shares in 2016, when he exercised options and liquidated some of the newly acquired stock to cover about $590 million of income taxes.
In his Nov. 6 poll announcement, Musk wrote that "much is made lately of unrealized gains being a means of tax avoidance, so I propose selling 10% of my Tesla stock." Almost 58% of the 3.5 million votes were cast in favor of a sale.
Musk, 50, is the world's richest person with an almost $300 billion fortune, according to the Bloomberg Billionaires Index.
