Elon Musk's xAI, recently rebranded as SpaceXAI, is leasing its Colossus 1 AI supercomputer to competitor Anthropic in a deal that could generate $5 to $6 billion in annual revenue. Announced May 6, 2026, the arrangement grants Anthropic access to over 220,000 NVIDIA GPUs while xAI shifts its operations to the newer Colossus 2 cluster.
The lease comes as xAI positions for an IPO valued at $75 billion or more. For Anthropic, backed by a $5 billion commitment from Amazon, the deal provides critical compute capacity to scale its Claude AI models. For xAI, it turns idle infrastructure into a recurring revenue stream ahead of its public debut.
Investors should watch the lease terms, Anthropic's reliance on Amazon's cloud, and how xAI prices its IPO. A $75 billion valuation with $5-6 billion in lease revenue suggests the market expects significant growth from xAI's own products.
