Elon Musk’s personal wealth is now $222 billion, widening his gap as the richest person in the world according to Bloomberg’s Billionaires Index.

Musk’s personal wealth skyrocketed an extra $10.6 billion after a secondary share sale by investors, announced last week, valued SpaceX over $100 billion, CNBC reported.

Jeff Bezos, the founder of Amazon, follows Musk with a net worth of $191.6 billion. Musk tweeted a second-place medal at Bezos early today.

Listen and be open, but don’t let anybody tell you who you are. This was just one of the many stories telling us all the ways we were going to fail. Today, Amazon is one of the world’s most successful companies and has revolutionized two entirely different industries. pic.twitter.com/MgMsQHwqZl

Thanks to both Musk’s Tesla shares and his majority stake in privately-held SpaceX, where he serves as CEO, Musk has accumulated vast wealth.

Musk gained $8.6 billion since Friday’s closing and more than $52 billion year-to-date, the Bloomberg Billionaires Index says.

Tesla shares are also climbing, as they recover from a rocky year.

They are up 13% year-to-date, far less than its 743% gain in 2020. Still, that’s a big improvement from when they were down 22% for the year in May.

Musk got $0 in pay in 2020, according to a company filing, but he did receive stock options during the year that are now worth $22 billion.

And those options are worth far more due to the rise in stock price.

Musk and Bezos — the two richest men on earth — are embroiled in a billionaire space race. Even before it launched the first tourism mission to space on Inspiration4 in September, Musk’s SpaceX won massive NASA and US military contracts and flew the most powerful rocket in operation.

Bezos, who founded Blue Origin in 2000, and billionaire Virgin-brands owner Richard Branson, both travelled to space last summer.

A June ProPublica report found that some billionaires, including Elon Musk, Bill Gates and Jeff Bezos, pay minimal income tax compared to the vast majority of Americans, despite their immense wealth. Nothing revealed in the report was illegal.

Meanwhile, the US economy is still recovering from the Covid-19 recession. Median household income fell 2.9% in 2020 to $67,521, the first statistically significant decline since 2011.

September’s job report marked the second straight month in which the economy added far fewer jobs than expected.
