Elon Musk is roughly $30 billion away from a milestone no human has ever reached. With SpaceX’s IPO now officially on the runway, that gap is about to close.

The rocket company filed its S-1 registration with the SEC on May 20, targeting a share price of $135 and a valuation in the neighborhood of $1.75 to $1.8 trillion. If the offering prices as expected, Musk’s 42% stake, representing approximately 6.4 billion shares, would be worth around $866.5 billion on its own. Stack that on top of his Tesla holdings, estimated at roughly $300 billion, and you’re looking at the world’s first verified trillionaire.

The biggest IPO ever, by a wide margin

SpaceX is aiming to raise approximately $75 billion in the offering, which would make it the largest IPO in history. For context, the previous record holder was Saudi Aramco’s 2019 debut. SpaceX is set to surpass it comfortably.

The company plans to begin trading on June 12 under the ticker SPCX. Reports indicate the offering has already been oversubscribed multiple times over.
