Anthropic has confidentially filed a draft Form S-1 with the U.S. Securities and Exchange Commission, giving the artificial intelligence company the option to go public after the SEC completes its review.

Anthropic said it has not yet determined how many shares it would sell or what price it would seek in an offering.

The disclosure was issued under Rule 135 of the Securities Act of 1933. The company said any offering activity would take place only through the registration process required under federal securities law.

Founded in 2021 by former OpenAI employees, Anthropic has quickly established itself as a key player in artificial intelligence, building tools that are reshaping how businesses approach areas like coding and cybersecurity.

Last month, Anthropic overtook OpenAI as the world’s most valuable startup after raising $65 billion in Series H, valuing the company at $965 billion. Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital led the funding round.

If Anthropic goes public at a $1 trillion valuation, it would instantly rank among the most valuable companies globally and could become the second- or third-largest IPO in history, trailing SpaceX and Saudi Aramco.

Anthropic's CEO, Dario Amodei's net worth has already hit $7 billion, according to Forbes. The article also noted that the company's seven cofounders are now worth a combined $116 billion.

The firm's latest AI model, Claude Opus 4.8, aims to deliver improved performance and new controls for customers and developers.

Anthropic is in the midst of working on Project Glasswing, an AI-assisted security testing effort that more than 50 organizations are collaborating on. Anthropic released an update regarding the project last week.

The company also recently announced a partnership with Elon Musk's SpaceXAI to use all of the compute capacity at SpaceX's data center Colossus 1 in Memphis, Tennessee. The partnership will give Anthropic more than 300 megawatts of additional capacity (over 220,000 NVIDIA GPUs) to deploy within the month and will increase limits for Claude Code and the Claude API.

Last month, Anthropic hired former Amazon Web Services (AWS) threat intelligence specialist Dlshad Othman to join its safeguards group. Othman will focus on areas spanning influence operations, surveillance, and cyber threat investigations.

The AI company also brought on the co-founder of OpenAI and former director of artificial intelligence and Autopilot Vison at Tesla, Andrej Karpathy. He is expected to create a new team focused on using Claude itself to speed up research on pre-training, an Anthropic spokesperson told TechCrunch.
