AI compute stocks rally as Broadcom structures $63B financing for Anthropic chips

The structure matters more than the headline number: Broadcom is using an SPV backed by major banks and asset managers to convert Anthropic's future compute needs into lease payments, moving chip demand off Anthropic's balance sheet and onto financiers. That is effectively a vendor-financing model for AI infrastructure, and the index-wide rally suggests the market read it as validation of the whole accelerator supply chain, not just Broadcom. The open question is whether this template spreads to other model developers, and how the disclosed long-term commitments interact with delivery timelines that only begin in 2027.
