In early November, the world's richest person tweeted that he would sell 10% of his stock if users of the social media platform approved. A majority of them had agreed with the sale.

Since Nov. 8, Musk has exercised options to buy 10.7 million shares and sold 10.1 million shares for $10.9 billion.

Following a flurry of options exercise, Musk still has an option to buy about 10 million more shares at $6.24 each, which expires in August next year.
