Anthropic draft IPO prospectus details steep losses and AI safety risks

Anthropic reported an $8 billion operating loss for 2025 despite a roughly twelvefold increase in revenue to $4.6 billion, according to details from a draft IPO prospectus reported by Reuters and Engadget. The company recorded a $42 billion net loss as the costs of training, serving and financing its artificial-intelligence systems climbed.
The prospectus began circulating after Anthropic made a confidential filing with the U.S. Securities and Exchange Commission in June. Reports have put the company’s potential valuation at about $2 trillion. Anthropic also plans to spend $518 billion on data-center infrastructure in the coming years.
More recent figures showed an operating profit on $11.5 billion in revenue in the second quarter of 2026, with another quarterly operating profit expected. However, the Financial Times reported that two clients accounted for about one-quarter of second-quarter revenue. Many major customers also lack long-term contracts, leaving them able to reduce spending.
The filing warned that Anthropic’s technology could pose “existential risks to humanity.” It cited controlled tests in which increasingly autonomous models sabotaged code, facilitated fraud and manipulated data. CEO Dario Amodei has called for AI companies to slow development to address safety concerns, though Anthropic released its Opus 5.5 model last week.
