Judge approves $1.5B Anthropic settlement over pirated books used to train Claude
A federal judge approved a $1.5 billion settlement between Anthropic and plaintiffs over the use of pirated books to train the Claude AI models. The case, brought by authors including Carol Bartz, is one of the largest copyright settlements in AI training data litigation. The outcome sets a significant precedent for how AI companies may be held liable for training data sourcing.

Anthropic and Amazon Expand Collaboration for Up to 5 Gigawatts of New Compute
Anthropic has signed a major expanded agreement with Amazon committing over $100 billion to AWS technologies over ten years, securing up to 5GW of compute capacity for training and deploying Claude across Trainium2 through Trainium4 chips. Amazon is investing an additional $5 billion in Anthropic today, with up to $20 billion more possible in the future, building on $8 billion previously invested. The deal includes nearly 1GW of Trainium2 and Trainium3 capacity coming online by end of 2026, expanded inference in Asia and Europe, and the full Claude Platform becoming available directly within AWS. Anthropic disclosed its run-rate revenue has surpassed $30 billion, up from approximately $9 billion at end of 2025.
Anthropic donates additional $20M to Public First Action, totaling $40M for AI policy education
Anthropic is contributing an additional $20 million to Public First Action, a non-partisan organization focused on AI public education and policy advocacy, bringing total support to $40 million. The announcement cites accelerating AI capabilities—including Claude Mythos Preview's discovery of thousands of high-severity software vulnerabilities—as justification for urgent policy action. Anthropic uses the occasion to reiterate its Advanced AI Framework, calling for government verification of safety claims, civil enforcement mechanisms, and the ability to slow or block deployment of catastrophically risky models. The donation also signals Anthropic's continued push for export controls on advanced chips and measures against illicit model access.
Andrew Ng commentary on Anthropic's Claude Fable 5 restrictions and U.S. export controls on frontier AI models
Andrew Ng's The Batch editorial covers two significant recent events: Anthropic releasing Claude Fable 5 (a guardrailed version of Claude Mythos 5) with terms restricting use for competing LLM development, and the U.S. Government applying export controls via the Commerce Department that forced Anthropic to disable global access to Fable. Ng argues these moves demonstrate how private companies and governments can suddenly restrict AI access, accelerating global interest in AI sovereignty and open-source alternatives. The piece also notes that independent evaluators struggled to assess Claude Fable 5 due to model routing behavior and Anthropic's new data retention policy.
Anthropic raises $580M Series B to advance AI safety and interpretability research (2022)
Anthropic raised $580 million in a Series B round in April 2022, led by Sam Bankman-Fried of FTX, to fund large-scale infrastructure for AI safety research. The company, then ~40 people, outlined work on interpretability, steerability, and robustness of large language models. The round is historically notable both for Anthropic's early safety-focused mission and for the involvement of Sam Bankman-Fried, who was later convicted of fraud in the FTX collapse.
Anthropic Publishes Updated Claude's Constitution (Jan 2026 Revision)
Anthropic has released an updated version of Claude's Constitution, the explicit set of principles governing Claude's values and behavior under the Constitutional AI (CAI) framework. The post explains how CAI uses AI-generated feedback rather than large-scale human feedback to train models toward helpful, honest, and harmless behavior, with the constitution guiding both self-critique/revision and reinforcement learning phases. The constitution draws from sources including the UN Declaration of Human Rights, DeepMind's Sparrow Principles, Apple's terms of service, and Anthropic's own safety research. Anthropic frames the constitution as a work-in-progress and invites broader participation in designing AI constitutions.
Anthropic and Teach For All Launch Global AI Training Initiative for Educators in 63 Countries
Anthropic is partnering with Teach For All to provide Claude access and AI training to over 100,000 teachers and alumni across 63 countries through the AI Literacy & Creator Collective (LCC). The initiative positions educators as co-architects of AI development, with teachers providing product feedback directly to Anthropic while building classroom tools using Claude Artifacts. The program includes a live learning series, a peer community hub with 1,000+ educators, and a Claude Lab innovation space with direct access to Anthropic's product team. Early deployments include a climate curriculum in Liberia and a gamified math app in Bangladesh.
Anthropic raises Series E at $61.5B post-money valuation
Anthropic has closed a $3.5 billion Series E round at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners with participation from Bessemer, Cisco, Fidelity, General Catalyst, Salesforce Ventures, and others. Proceeds will fund next-generation AI system development, expanded compute capacity, mechanistic interpretability and alignment research, and international expansion. The raise follows the launch of Claude 3.7 Sonnet and Claude Code, with Anthropic citing strong enterprise adoption across customers including Cursor, Zoom, Snowflake, Pfizer, and Amazon's Alexa+.
U.S. Department of War bans Anthropic, contracts OpenAI for classified AI systems after standoff over safety restrictions
The U.S. Department of War designated Anthropic a supply-chain risk to national security after the company refused to remove restrictions on Claude's use for domestic surveillance and autonomous weapons, effectively banning it from military and contractor use. OpenAI signed a contract allowing use of its models 'for all lawful purposes' with ambiguous carve-outs for surveillance and autonomous weapons, which Altman later called rushed and renegotiated. The standoff culminated in a Trump Truth Social post threatening civil and criminal consequences against Anthropic, followed by Hegseth's formal designation. The episode marks a significant precedent: the supply-chain risk designation, previously applied only to foreign companies, was used against a U.S. AI lab over its own usage policies.
