Anthropic to File IPO Prospectus as Early as Friday
Tap title to read story
Anthropic (ANTH.PVT) is set to publicly file its S‑1 investor prospectus as soon as Friday, according to three people familiar with the artificial intelligence firm’s plans.
The filing would clear a key procedural hurdle toward a potential November listing, though the timing remains subject to market conditions.
Anthropic confidentially submitted a draft IPO registration statement to the Securities and Exchange Commission in June, and under SEC rules must make its registration materials available 15 calendar days before the start of its formal investor roadshow.
The company pulled in $16.3 billion in revenue over the first six months of 2026 and reported a net loss of over $80 billion, according to a Tuesday Wall Street Journal report.
Wall Street is anticipating that the company could raise as much as $100 billion at a $2 trillion valuation, Reuters previously reported.
Anthropic is spending billions on AI infrastructure to train and run its suite of Claude models, working with Google and Amazon and renting GPU capacity from SpaceX’s Colossus 1 data center.
