As of the end of 2021, Musk held about 21.2% of Tesla (actually holding 231,715,206 shares of the company), and at Monday's closing price of $875.76 per share, Musk's 21.2% stake is worth about $202 billion. A similar document from a year ago showed that by the end of 2020, Musk held 22.4% of Tesla's shares, and Musk's shareholding ratio was declining overall, but the overall difference was not much.
Musk's most recent filing with the SEC came shortly after Musk donated more than 5 million TSLA shares to an undisclosed charity last year, and Musk began donating TSLA shares on November 19, 2021, just days after David Beasley, head of the United Nations World Food Programme (WFP), gave a full explanation of the organization's plans to tackle the hunger crisis.
Back in November 2021, Musk launched a Tesla stock sales spree by conducting a poll on Twitter asking if users of the social media platform should sell about 10 percent of their stake in the electric car maker, and as of the end of December, Musk had sold 15.7 million shares of TSLA shares, but Musk was ultimately able to increase his TSLA shares by exercising stock options to buy more shares at $6.24 per share.
Musk also pointed out in December that he will pay about $11 billion in taxes due to his sell-off of Tesla stock, which also makes Musk's 2021 tax bill one of the largest in U.S. history, which is equivalent to about $1 million in taxes paid every day since Musk came to the University of Pennsylvania in 1992 to study business and physics.
