Elon Musk's companies, including SpaceX, Tesla, xAI, and X (formerly known as Twitter), require a significant number of GPUs for AI and HPC projects. Due to a shortage of GPUs, Musk's new AI venture xAI, established in March 2023, has received $6.4 billion in funding and is looking to build a supercomputer with 100,000 Nvidia GPUs in a Memphis factory. The project, supported by industry partners like Supermicro and Juniper Networks, is ambitious and faces power and infrastructure challenges.
