Leaked excerpts from SpaceX's confidentially filed $1.75 trillion S-1 form shed some light on the company's business plans, which includes plans for it to build its own GPUs. The listing notes its intent to invest billions in production of some of the processors it needs internally as it does not have long-term supply agreements with its silicon suppliers. Interestingly, the silicon to be produced in-house is said to be GPUs, not specialized ASICs for AI acceleration, according to Reuters. However, the naming convention is still up for debate. The news comes on the heels of yesterday's blockbuster announcement that Musk will use Intel's 14A process node in its new TeraFab chipmaking venture, with SpaceX managing the manufacturing facilities.

The S-1 form seen by Reuters mentions 'manufacturing our own GPUs' as one of the reasons of the 'substantial capital expenditures' the company will incur in the future as it appears to lack ' long-term contracts with many of our ​direct chip suppliers.' While the fact that SpaceX will build and operate its own high-volume semiconductor manufacturing facility to produce silicon developed at Tesla was confirmed by Elon Musk, chief executive of Tesla and SpaceX, last night, the firm's plans to build its 'own GPUs' seems like something new.

Given the inconsistent naming of its AI accelerators at Tesla — mostly because they are aimed at very specific workloads — it is hard to verify whether SpaceX means producing Tesla's AI5 and/or AI6 hardware, or indeed in-house designed 'GPUs.'
