The highly anticipated SpaceX (NASDAQ:SPCX) IPO crowned the world’s first trillionaire, catapulting CEO Elon Musk‘s net worth. The IPO also helped boost the wealth of other SpaceX early investors, including Elon’s younger brother Kimbal Musk.

Kimbal Musk Net Worth Surges

Two years younger than Elon, Kimbal Musk is the lesser-known Musk brother, but his net worth may become more well known going forward as a member of the billionaire club once again.

Kimbal Musk is worth an estimated $1.6 billion according to Forbes, ranking as the 2,485th-richest person in the world.

Musk’s net worth comes from similar places as his older brother, but in smaller quantities. Kimbal owns .03% of Tesla Inc (NASDAQ:TSLA) and around .05% of SpaceX. These two places make up the majority of his wealth.

The younger Musk has served on the Tesla board of directors since 2008 and previously served on the SpaceX Board of directors from 2002 to 2022.

Kimbal co-founded software company Zip2 Corporation with Elon. Compaq acquired the company for more than $300 million in 1999.

The younger Musk was briefly a billionaire back in 2020 thanks to a surge in Tesla’s stock price. Kimbal has sold some of his stock and options in Tesla over the years.
