SpaceX is about to become the most valuable company to ever go public, and Nvidia wants everyone to know it helped build the engines. Not the rocket engines, the computational ones.

Nvidia is celebrating its long-running partnership with SpaceX as the Elon Musk-led company prepares for an IPO priced at $135 per share. The offering is expected to raise $75 billion, which would make it the largest IPO in US history and peg SpaceX’s valuation at roughly $1.8 trillion.

A partnership that started with a single supercomputer

The collaboration traces back to 2016, when Nvidia delivered its first DGX-1 supercomputer to SpaceX. Nearly a decade later, Nvidia now provides SpaceX with a suite of space-specific computing platforms, including the Space-1 Vera Rubin Module, IGX Thor, and Jetson Orin, purpose-built to operate in the unique thermal, radiation, and power constraints of outer space.

The partnership centers around AI computing for rocket design and manufacturing, but the scope has expanded to include SpaceX positioning itself as a potential operator of orbital data centers.
