# Anthropic

## Overview
Frontier AI safety laboratory founded by former OpenAI VP of Research Dario Amodei and President Daniela Amodei. Anthropic occupies the central tension in AI alignment: the company most associated with safety-first development that is simultaneously racing to scale at unprecedented speed. Their Claude model family has become the dominant enterprise AI platform, particularly for coding.

## Current State
- Claude Opus 4.6 (1M token context, Agent Teams) and Sonnet 4.6 (Feb 2026) are current frontier models
- 40% of enterprise LLM spending — surpassed OpenAI as enterprise leader
- Claude Code holds 54% of enterprise coding market, hit $1B ARR faster than any enterprise software product in history
- $19B annualized revenue as of March 2026, projecting $70B by 2028
- Amazon partnership: $4B+ investment, Project Rainier (dedicated Trainium2 data center)

## Timeline
- **2021** — Founded by Dario and Daniela Amodei after departing OpenAI
- **2023-10** — Published Collective Constitutional AI research
- **2025-11** — Published "Natural Emergent Misalignment from Reward Hacking" (arXiv 2511.18397) — most significant alignment finding of 2025
- **2026-02-17** — Released Claude Sonnet 4.6
- **2026-02-25** — Abandoned binding Responsible Scaling Policy in favor of nonbinding safety framework, citing competitive pressure
- **2026-02** — Raised $30B Series G at $380B valuation

## Competitive Position
Strongest position in enterprise AI and coding. Revenue growth (10x YoY) outpaces all competitors. The safety brand was the primary differentiator — the RSP rollback creates strategic ambiguity. CEO publicly uncomfortable with power concentration while racing to concentrate it.

The coding market leadership (Claude Code at 54%) represents a potentially durable moat: developers who build workflows around Claude Code face high switching costs, and coding is the first AI application with clear, measurable ROI.

## Relationship to KB
- [[emergent misalignment arises naturally from reward hacking as models develop deceptive behaviors without any training to deceive]] — Anthropic's most significant alignment research finding
- [[voluntary safety pledges cannot survive competitive pressure because unilateral commitments are structurally punished when competitors advance without equivalent constraints]] — the RSP rollback is the empirical confirmation of this claim
- [[safe AI development requires building alignment mechanisms before scaling capability]] — Anthropic's founding thesis, now under strain from its own commercial success
