SpaceX (SPAX.PVT) officially kicked off its IPO process, which could result in the biggest public offering ever.

The reusable rocket and space exploration company confidentially filed for its IPO with the SEC, Bloomberg News reported on Wednesday. Though details won’t be available until closer to its official listing, The Information and Bloomberg reported earlier that SpaceX was expected to raise up to $75 billion in its offering.

Though SpaceX was most recently valued at $1.25 trillion, Bloomberg reports the company’s valuation was on track to hit $1.75 trillion, putting it on par with companies like CEO Elon Musk’s Tesla (TSLA).

SpaceX won’t decide the actual size of the offering and valuation until a few weeks before the IPO, with the company targeting a June listing. Bloomberg also reports the company is considering a dual-class share structure in the listing that would potentially give insiders such like CEO Elon Musk extra voting power.

In addition, SpaceX may reportedly allow more retail investors to participate in the IPO than is typically normal, as Musk has been known to cater to individual investors in Tesla, for example. The individual investor portion could top 20% of offering, double the 10% normally allocated.

For Musk, SpaceX’s offering is the culmination of dream to build reusable rockets, and colonize Mars. Musk founded the company back in 2002, and by 2012 SpaceX began delivering cargo by rocket to the International Space Station.

Part of the big valuation story of SpaceX is Starlink, the satellite-based internet service that began operation in 2019. Starlink reportedly generates the lion’s share of SpaceX’s profits, and its growth may be a reason why a SpaceX IPO would be lucrative at this time.

A SpaceX IPO would also bring another Musk company to the public fold, one that is increasingly connected to Musk’s other trillion dollar company, Tesla.

Last weekend Tesla and SpaceX announced Terafab, a joint venture designed to consolidate every stage of semiconductor production under one roof.

Terafab targets two primary chip types: an edge-inference processor optimized for Tesla's Full Self-Driving systems, Optimus humanoid robots, and Robotaxi fleets, and a high-power variant hardened for space environments, supporting SpaceX satellites, orbital data centers, and xAI initiatives.

The SpaceX IPO will help fund those orbital data centers, a priority for Musk who believes it will be cheaper to produce AI compute in space versus on Earth.

This follows Musk’s move in February to change SpaceX’s original mission from colonizing Mars, to a closer (and more financial feasible) target in the Moon.

While Wall Street may be coming around on orbital data centers, which once seemed like science fiction, spending billions on a mission to Mars was too far a stretch for investors.

As SpaceX hones and tweaks its story to investors as it seeks billions in fresh capital, Musk will, of course, benefit from the offering beyond raising funds for his SpaceX missions.

Musk would reportedly own around 42% of SpaceX before any dilution. SpaceX would need to reach $1.6 trillion in valuation for Musk to become the world’s first trillionaire.
