SpaceX is no longer a rocket company. Its impending IPO, targeting a valuation of $1.75 trillion, is a bet on becoming the infrastructure layer for AI compute in orbit. Starlink, with nearly 10,000 satellites and 10 million customers, is the current profit engine, reporting $4.4 billion in profit last year. But the growth lever is xAI, the lab Elon Musk merged into SpaceX, which lost $6.4 billion in the same period.
The plan hinges on Starship. Tim Cross of The Intelligence notes that if the vehicle achieves full reusability, it could slash launch costs from $4,000 per kilo to $200. That efficiency is necessary to carry the massive computing hardware Musk intends to put into orbit, powered by free sunlight and free from terrestrial permitting and grid constraints. The prospectus outlines a total addressable market of $28.5 trillion.
"Elon Musk is no longer selling rockets; he is selling a space-based AI future."

This transforms SpaceX from a launch provider into what Alex Wiesner-Gross on Moonshots calls the "Microsoft of space." It aims to own the digital and physical labor layers, building a "Dyson swarm" to dominate the infrastructure of the solar system. The strategy mirrors Microsoft's play with OpenAI: own the compute, the data centers, and the software running on top.
Investors face a choice between a proven launch monopoly, which handles 90% of global payloads, and a speculative AI bet that currently burns more cash than the entire company earns. The valuation, 90 times last year's revenue, rests on the thesis that orbital data centers will provide critical, space-based compute and data links for the next generation of AI. The pivot is a packet-switched solar system, decoupling cargo from transport to become the railroad of the new frontier.
