SpaceX says it plans to sell shares and raise up to $75 billion when it goes public this month. This could be the biggest stock market debut ever. It could also make Elon Musk the world’s first trillionaire.

SpaceX said it will sell 555.6 million shares at $135 each. The company could be worth $1.77 trillion. Musk is SpaceX’s CEO, chief technical officer, and chairman.

The filing says Musk would have 82.4% of the voting power in the company. Forbes says Musk is now worth $826 billion, and his SpaceX stake is worth $542 billion. If SpaceX is worth $1.77 trillion, his wealth could rise by $223 billion.

SpaceX is still losing money. The filing says it lost $2.6 billion from operations last year on $18.7 billion in revenue. The company plans to use the money from the IPO for its AI work, rockets, and Starlink Mobile satellites.
