Anthropic targets a mega-IPO before Thanksgiving, with up to $42B of Broadcom financing for TPUs

Anthropic's S-1, first reported by the New York Times on September 29 and expanded by Reuters and Bloomberg on October 1, describes a listing timed before Thanksgiving. The valuation could top $2 trillion, which would make it one of the largest IPOs ever. The prospectus also shows the scale of the bet: a $42 billion net loss in 2025 and $518 billion in planned infrastructure spending.

The Broadcom piece is the novel financial engineering. Broadcom will lend up to $42 billion in convertible financing so Anthropic can lease chips under a $125.2 billion, five-year TPU commitment. In effect, a chip supplier is financing its own customer's purchases. That reduces Anthropic's upfront cash needs and binds Broadcom's custom-silicon business to Anthropic's growth. It also deepens Anthropic's reliance on Google-designed TPUs relative to NVIDIA GPUs.

The competitive context is a compute-financing arms race. OpenAI, Meta and xAI are all signing multi-hundred-billion infrastructure deals, and vendor financing is becoming a standard tool. Anthropic's commercial momentum supports the pitch. Opus 5.5 is drawing developer migrations, and on r/singularity a post saying junior-level work 'now takes Opus 5.5 minutes' earned 484 upvotes.

The risks are real. Loss figures at this scale will invite scrutiny of unit economics. Converts tied to a supplier create potential conflicts of interest. An FTC probe into AI product risks that names Anthropic is also active. Reliability is another concern: a major Claude.ai and API outage on September 29 revived calls for multi-provider fallback. Watch for the pricing range, the dual-class structure, and how the roadshow addresses the $518 billion capex plan.
