🚀xAI Locks in Billions for Anthropic's Colossus Cluster
Why SpaceX is locking in xAI for a massive, short-term deal
TL;DR
xAI has signed a $billion+ monthly deal for exclusive use of Anthropic's Colossus cluster. The agreement is for 180 days with an exit clause, raising questions about SpaceX's long-term strategy.
xAI just locked in a multi-billion dollar lease for Anthropic’s Colossus supercomputing cluster, but the deal is only for 180 days. This short-term arrangement raises eyebrows given the astronomical monthly fees involved. Why would xAI commit to such a pricey setup without a longer-term agreement? It's unclear if SpaceX will follow suit or if this is just a test run for Anthropic’s AI ambitions. The lease includes a mutual cancellation clause, allowing either party to terminate with 90 days' notice. This deal could signal a shift in how tech giants approach supercomputing resources.
