# What the filing says Anthropic, the developer of the Claude family of models, filed a confidential S-1 with the SEC on June 1 as it moves toward a Nasdaq initial public offering. The filing discloses financial and commercial commitments that make clear how the company is financing rapid model development and deployment.
# Losses and the reason behind them The company recorded a net loss of nearly $42 billion in 2025, about five times the $8.3 billion loss reported in 2024. The filing attributes the jump to extraordinary spending on computing infrastructure required to train and operate large AI models. Those infrastructure costs are the main driver of the widening losses despite surging revenue.
# Revenue growth in parallel
# Infrastructure and contractual commitments The prospectus lays out large, multi-year infrastructure commitments totaling about $518 billion. Two named components account for a sizable share:
- A pledge of more than $100 billion to Amazon Web Services over ten years.
- A SpaceX agreement described as $15 billion per year running through May 2029.
These commitments reflect a strategy of securing massive compute capacity through long-term contracts rather than relying only on spot market purchases.
# IPO timing, valuation, and underwriters Anthropic aims to list on Nasdaq as early as mid-October 2026, potentially completing the process before the U.S. midterm elections. The company is targeting a valuation in the neighborhood of $2 trillion. Major banks—Morgan Stanley, Goldman Sachs, and JPMorgan—are named as underwriters overseeing the offering.
# Why the filing matters for markets
# Political and regulatory context Completing an IPO before midterms puts Anthropic in public markets during a period of potential political and regulatory flux. The filing highlights the interplay between product rollout, capital needs, and a regulatory environment that could shift depending on electoral outcomes.
# Bottom line Anthropic as a company pursuing rapid commercial scale with enormous compute commitments. That approach has driven explosive revenue growth but also produced unprecedented losses. The upcoming IPO will be a practical test of whether public investors will finance continued heavy spending for frontier AI at the valuation levels Anthropic is targeting.
