Elon Musk has signed a surprise deal with Anthropic, allowing him to turn unused compute into revenue before an expected SpaceX IPO. The deal helps Anthropic address one of its most pressing problems, a severe compute deficit. SpaceX will provide Anthropic with the entire capacity of its Colossus 1 data center, amounting to over 300 megawatts of new capacity (over 220,000 Nvidia GPUs) within the month. The move comes as Musk is embroiled in a lawsuit against OpenAI, the AI lab he co-founded, which is Anthropic's biggest competitor. The agreement allows both companies to secure financial stability and continue their exponential revenue growth.
