The company is mostly known for its space endeavors, like shipping crew and cargo to the International Space Station, deploying satellites, and its Starlink service β€” but SpaceX merged with x.com and xAI just this February.

Back then, the combined company was valued at $1.25 trillion, and it’s IPO is expected to be the largest in history β€” in addition to being the first major AI lab to go public, as a small test of market appetite.

SpaceX spent 60% of its $20 billion in capital expenditures on its xAI division in 2025, while losing billions and only seeing growth of about 22%, TechCrunch writes.

In another TechCrunch report, they note from the filing that xAI lost about $6.5 billion in 2025, and is making $365 million in subscriptions together with x.com.

What xAI does have is massive compute resources, which Anthropic is renting for $15 billion per year, Axios reports β€” and they are looking to expand more.

While the IPO might be tempting for a whole host of reasons, Elon Musk will retain a supermajority in the company from his 85% stock ownership, NBC News says.
