Anthropic is set to publicly file its S-1 registration as soon as Friday, moving from a confidential June submission to the next regulatory step that clears the way for a November listing and opens detailed financials and risks to public investors. The offering is widely expected to become the largest IPO ever, surpassing SpaceX, and is being watched as a decisive test of investor appetite for the AI sector. Founders Dario and Daniela Amodei lead a company that has established a strong enterprise foothold with its Claude products, including Claude Code and Claude Cowork, and has been pitching institutional investors ahead of the public filing.
The company has spent billions on compute infrastructure, partnering with Google and Amazon and renting GPU capacity from SpaceX’s Colossus 1 data center. Reported results show $16.3 billion in revenue for the first half of 2026 and a Wall Street Journal-reported net loss exceeding $80 billion, while the Financial Times reported $16.8 billion in third-quarter revenue (up from $11.5 billion in Q2) and adjusted profitability. Wall Street anticipates a roughly $100 billion raise at about a $2 trillion valuation. The timing is crucial amid a cooling IPO market - recent debuts and shelved listings have dented enthusiasm - so Anthropic’s pricing and reception will set a benchmark for other AI-related public offerings.
