Anthropic
privateAnthropic is an AI safety company founded in 2021 by Dario Amodei and Daniela Amodei, along with several former OpenAI researchers including Tom Brown (GPT-3 first author), Jared Kaplan (scaling laws co-author), Sam McCandlish, and Chris Olah. Organized as a Public Benefit Corporation focused on AI safety research. Raised $30B in February 2026 at a $380B valuation, with Amazon ($8B total), Google, and others as key investors. Revenue reached ~$19B ARR by March 2026.
The Claude model family has rapidly advanced from Claude 1 (2023) to Claude Opus 4.6 (2026, AA index 46, 1M context), consistently ranking among the top frontier models. Claude 4 Opus set SWE-bench records (72.5%), and Claude 4.5 Opus was the first model to exceed 80% on SWE-bench Verified. Claude Code, an agentic coding CLI launched in 2025, reached $2.5B+ ARR by March 2026.
Anthropic's research contributions are foundational: Constitutional AI (2022) introduced RLAIF with explicit principles, replacing human preference labeling with AI self-critique. Scaling Monosemanticity (2024) used sparse autoencoders to extract interpretable features from Claude 3 Sonnet at production scale. The company also created the Model Context Protocol (MCP), an open standard for LLM-tool integration adopted by OpenAI, Google, and others.
