The filing lays out what would be one of the largest stock listings ever attempted, testing public-market appetite for artificial intelligence spending at a scale no prior tech debut has matched. The document shows revenue climbing alongside expenses tied to compute and talent, a pattern that has defined the AI sector’s growth since 2023.

The prospectus, first detailed in a Reuters report, describes the company’s ambition in sweeping terms, framing artificial intelligence as a transformation on the scale of industrialization and the arrival of electricity.

Anthropic, the maker of the Claude family of AI models, was founded in 2021 by former OpenAI researchers including Dario Amodei and Daniela Amodei.

A companion Reuters piece placed the offering among a wave of mega-IPOs that includes SpaceX and Saudi Aramco in scale.

An initial public offering is the process by which a private company sells shares to public investors for the first time, creating a market price that anyone can buy or sell against.

Anthropic’s costs have grown faster than its topline in recent quarters, driven largely by the price of renting or building the data center capacity needed to train and run large language models. That cost structure is now the central risk investors will price into any valuation above $2 trillion.

Anthropic has raised capital from investors including Amazon and Google in recent years, building toward a public listing that industry watchers have anticipated since early 2026.

The company’s rivals, OpenAI and xAI, have pursued their own paths to liquidity through private funding rounds rather than public markets, making Anthropic’s filing the first true test of investor appetite for a frontier AI lab’s full financial picture.

What remains unresolved is whether public investors will tolerate the widening gap between revenue and spending that has defined AI lab economics since ChatGPT’s 2022 debut. The filing does not disclose a specific listing date.

Underwriter terms and share pricing will determine whether the $2 trillion target survives contact with public markets.
