Anthropic Wins Partial Copyright Ruling on AI Training
A US federal court in the Northern District of California, led by Judge William Alsup, has partially ruled in favor of AI developer Anthropic in a copyright lawsuit brought by authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson. The court determined that using legally acquired and digitized books to train large language models (LLMs) constitutes fair use, citing the transformative purpose and lack of direct market harm. However, the court distinguished Anthropic's additional practice of downloading over seven million e-books from pirate sites, which will be addressed in a separate proceeding. The ruling is significant as a first precedent favoring the AI industry, potentially influencing dozens of similar pending lawsuits against AI companies, including those against OpenAI. The decision does not address whether AI-generated outputs themselves may infringe copyright.
Landmark court ruling on AI training and fair use, affecting AI model development used across AdTech/MarTech and other industries, potentially shaping future copyright litigation.

AI Price War: OpenAI Gains Ground on Anthropic
The AI price war is intensifying, with OpenAI gaining significant ground on Anthropic among business customers. According to a Wall Street Journal report, spending on OpenAI and Anthropic models via the OpenRouter platform was nearly evenly split in September among roughly 120,000 companies using both, a shift from January when Anthropic held about 75% of that spending. OpenAI's aggressive price cuts on its GPT-5.6 lineup, including an 80% reduction on its smallest model Luna and 20% on Terra, are driving this change. Companies are increasingly prioritizing cost, combining multiple providers and using cheaper models for simpler tasks. Anthropic faces its own challenges, including capacity issues with Claude Code and data retention criticism. Both companies are preparing for IPOs, needing to demonstrate sustainable revenue to justify valuations exceeding $1 trillion.
