Anthropic IPO prospectus shows $42 billion 2025 loss and $518 billion spending plans

The useful part

A listing at the reported scale would set the first public-market benchmark for a pure-play AI lab, so the prospectus numbers are likely to be read across AI and chip stocks, which have sold off recently. The SpaceX debut gives investors a reference for how a mega-IPO trades after pricing, and a large new supply of AI equity, followed by a possible OpenAI listing, could weigh on existing AI names if appetite for the trade fades. The reported delay until after the midterms leaves time for rates, AI sentiment and the compute spending debate to shift before any pricing.

How it works

• Anthropic's prospectus pairs a 12-fold revenue jump with huge losses and half a trillion dollars of compute commitments, setting up a listing that would test how Wall Street prices AI.
• Anthropic's IPO prospectus, seen by Reuters, shows a net loss of $42 billion in 2025 and plans to spend $518 billion on cloud, computing and infrastructure obligations in coming years.
• OpenAI scraps GPT-6.1 Astra release over safety concerns, WSJ reports --- Summary:
• Around $34 billion of the net loss was an accounting charge tied to the estimated value of financing that could convert into shares, not cash spent on the business.
• Anthropic above $2 trillion, more than double its own estimate of around $965 billion in May, with a debut likely after the November midterms.
