You hear about Claude all the time, but who is behind it, and how does it make money? Anthropic was founded in 2021 by a group that left OpenAI. It has made AI safety its calling card and operates as a public benefit corporation (PBC), whose charter places public benefit alongside shareholder interests. Most of its customers are businesses and developers.
Remember it in one line: a company betting that businesses will pay for AI that is safer and better at coding.
Key data snapshot

A quick guide in seven dimensions
1. Models and technology: Claude comes in several tiers: Fable, Opus, Sonnet, and Haiku, with a focus on long text and coding. There is also Mythos, available only to trusted organizations. A public “constitution” (Constitutional AI) guides model behavior. → The Claude model family
2. Growth engine: Claude Code drives paid adoption among businesses and developers and is one of the main engines of revenue growth. → How Claude Code became a growth engine
3. Market position: Anthropic focuses on businesses and coding, and competes with OpenAI for the same customers. → Anthropic vs OpenAI
4. Valuation and IPO: A private valuation is not a stock price, and ARR is not full-year revenue. These two articles break down its funding, revenue measures, and IPO progress. → Valuation and IPO, Complete IPO guide
5. Backers and compute: Amazon and Google are both major investors and compute suppliers, so they are a source of support and of dependence. → Backers and partners, The compute bet
6. Risks: Copyright lawsuits from several music publishers are still ongoing. The US Department of War (formerly the Department of Defense) labeled Anthropic a “supply-chain risk”: of the two designations, a district court struck down one, and an appeals court upheld the other in September 2026. → Risk list
7. Governance: A public benefit corporation charter plus a Long-Term Benefit Trust (LTBT). The LTBT is made up of trustees with no financial interest in Anthropic and elects some of the directors. According to the prospectus seen by Reuters, after listing the founders will hold 50.1% of the vote on key matters through a single Class F share, while the LTBT elects four directors. The question it must answer is sharp: when commercial pressure clashes with the safety mission, who decides? → Why a public benefit corporation?, Founding team
