Anthropic is a San Francisco–based AI company founded in 2021 by former OpenAI research leaders, including CEO Dario Amodei. Anthropic focuses on building large-scale AI systems with a safety-first approach, using its proprietary “Constitutional AI” method to align model behavior with human values. Its flagship product family, Claude, now includes the Claude 4.5 series—Opus, Sonnet, and Haiku—which deliver major improvements in reasoning, coding performance, and real-time interaction. Anthropic has also expanded into specialized offerings like Claude Code and deep enterprise integrations with AWS, Google Cloud, and a growing ecosystem of partners.
Anthropic closed a $13 billion Series F in September 2025, led by ICONIQ Capital, Fidelity Management, and Lightspeed Venture Partners, with participation from Altimeter Capital, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, General Catalyst, GIC (Pte) Ltd., Goldman Sachs Alternatives, Insight Partners, Jane Street, Ontario Teachers’ Pension Plan, the Qatar Investment Authority, TPG, and T. Rowe Price, at a $183 billion post-money valuation. Since then, the company has continued scaling infrastructure through multi-billion-dollar partnerships with Amazon, Google, and other cloud providers, and has formed a major strategic partnership with Accenture to drive enterprise adoption across regulated industries. Anthropic is also preparing for an eventual public listing, having begun working with advisors on long-term IPO planning.
Demand for Anthropic’s models has continued accelerating throughout 2025, with ARR climbing from $1B in December 2024 to over $5B by July 2025 and surpassing a ~$7B run-rate by October. The company remains on pace to reach ~$9B by year-end. According to recent industry analyses, Anthropic has now become the leading enterprise model provider (40% market share), ahead of OpenAI, driven largely by surging adoption of Claude for coding, automation, and knowledge-work applications. The company projects a $20B run-rate ARR by the end of 2026 in its base case and $26B+ in its best case, positioning it to become the fastest-growing enterprise software company in history.
