SpaceX’s blockbuster IPO filing included some out-of-this-world details, including a provision that founder Elon Musk would receive a massive bonus only if one million humans settled on Mars.

The bonus structure, outlined in SpaceX’s prospectus filed with US regulators on Wednesday, reads less like a compensation contract and more like a science fiction plot.

Musk’s bonus is contingent on SpaceX’s goal of raising the stock market value from $400 billion to $6 trillion — with the company taking a million people to a planet 140 million miles (225 million kilometers) away.

Musk describes that ambition as essential to the long-term survival of the human race, though most experts see it as at least decades away.

Still, Musk will do just fine if the IPO goes ahead as planned in the coming weeks.

At the company’s target valuation of $1.75 trillion, Musk’s current stake would be worth roughly $735 billion — before a single human sets foot on the Red Planet.

A second, smaller bonus ties an additional 60 million shares to a separate moonshot: building data centers in orbit capable of delivering 100 terawatts of computing power per year — a figure that dwarfs anything that exists on Earth today.

SpaceX filed for its long-awaited IPO on Wednesday, targeting a listing on the Nasdaq stock exchange under the ticker “SPCX” in what could be the largest public offering in Wall Street history.

The company’s Starship rocket — the latest iteration of which could launch Thursday — is clearly designed with Mars colonization in mind.
