Apollo, Blackstone back Anthropic’s $35 billion capacity expansion in new Broadcom tie-up

Apollo and Blackstone are financing a $35 billion expansion of AI computing capacity for Anthropic using Broadcom’s custom chips and networking solutions as part of a tie-up between the asset managers and the chipmaker.

The initial commitment will expand the Claude Code creator’s AI computing capacity by one gigawatt, ‌the companies said ⁠on ⁠Tuesday. One gigawatt is enough to power about 750,000 homes.

The capacity is expected to be deployed at Fluidstack-operated sites beginning mid-2026, with the cloud computing company providing the physical data-center infrastructure that will run Anthropic’s AI systems.
