Company Overview

Anthropic is the safety-first research lab that became OpenAI's strongest commercial rival. Founded in January 2021 by researchers who left OpenAI, it sells the Claude model family and the agent tools built on it, reaching $4.59 billion of revenue in 2025 and about a $65 billion annualized run-rate by July 2026. Its identity rests on Constitutional AI, mechanistic interpretability research and a Responsible Scaling Policy that ties deployment to capability thresholds, and on a corporate structure in which an independent Long-Term Benefit Trust appoints part of the board of a Delaware public benefit corporation. The company is headquartered in San Francisco, California.

Anthropic charges for Claude in four ways. Developers and enterprises pay per million tokens on the Claude API, where cache reads cost far less than fresh input ($0.20 per million against $4 on Claude Opus 5.5). Individuals and teams pay subscriptions across Claude Pro, Max, Team and Enterprise plans. Agent products carry their own budgets: Claude Code, generally available since May 2025, passed $2.5 billion of run-rate revenue by February 2026, and Cowork brought the same engine to non-technical work in January 2026. Claude is also resold through Amazon Bedrock, Google Cloud Vertex AI and Microsoft Azure Foundry, letting customers spend committed cloud budget on Claude. Spending is concentrated: the two largest customers each accounted for about 12 percent of 2025 revenue, while more than 500 customers spent over $1 million on an annualized basis as of February 2026, and eight of the Fortune 10 are customers.

Key Decisions & Impact

Set the Constitutional AI and Responsible Scaling approach, signed compute and distribution deals with Amazon, Google, Microsoft and NVIDIA, refused Department of Defense demands in February 2026 to drop limits on mass surveillance and fully autonomous weapons, and confidentially submitted a draft S-1 for a US listing on June 1, 2026.

Legacy

Co-founded Anthropic in January 2021 and has run it since. Revenue reached $4.59 billion in 2025 and an annualized run-rate of about $65 billion by July 2026, and the company was valued at $965 billion post-money in its May 2026 Series H.

Challenges & Strategic Context

Compute is both the binding constraint and the main cost. Anthropic spent $7.33 billion on compute and infrastructure in 2025 within $12.65 billion of total operating expenses, and its draft prospectus lists about $518 billion of long-term cloud and infrastructure commitments. It competes with OpenAI, Google DeepMind, Meta, xAI and Chinese labs that Anthropic has publicly accused of distilling Claude outputs. Legal and policy exposure is live: a $1.5 billion copyright settlement with authors received final approval in July 2026, music publishers sued again in August 2026, Reddit sued in June 2025, and the 2026 dispute with the US Department of Defense over surveillance and autonomous weapons limits went to court, where a judge granted Anthropic a preliminary injunction in March 2026.

Has Anthropic had any other chief executive?

No. Dario Amodei has been chief executive since the company was incorporated in January 2021. His sister and co-founder Daniela Amodei is president and runs the commercial and operating side of the business.

Why did Dario and Daniela Amodei leave OpenAI?

They left in late 2020 over differences about direction, arguing that commercial pressure following OpenAI's Microsoft partnership was outpacing alignment and safety work.

Revenue grew from $386 million in 2024 to $4.59 billion in 2025 and an annualized run-rate of about $65 billion by July 2026, the company was valued at $965 billion in May 2026, and it submitted a confidential draft S-1 on June 1, 2026.

Who else sits in Anthropic's leadership?

Daniela Amodei is president, Jared Kaplan is chief science officer, Krishna Rao is chief financial officer, Ami Vora is chief product officer, Mariano-Florentino Cuellar is chief global affairs officer, and Jack Clark leads policy.

How does the Long-Term Benefit Trust interact with the chief executive?

The trust holds no economic interest but has the right to appoint and replace part of the board over time, which places an independent check above management on decisions about frontier development.

What positions has Amodei taken in public policy?

He has testified before US lawmakers on AI risk, called publicly for pacing frontier development, refused Pentagon demands in February 2026 to drop limits on mass surveillance and autonomous weapons, and in September 2026 agreed to give independent evaluators permanent access to Anthropic models, comparing it to a food inspector.

What has Amodei said about AI and jobs?

In 2025 he warned that AI could eliminate a large share of entry-level white-collar work in fields such as finance, law and consulting, and Anthropic's own research found most business customers use Claude to delegate whole tasks rather than to collaborate.
