## Summary

In its IPO filing cover letter, Anthropic reaffirms that Claude will not show ads, saying advertising would add pressure to optimize for engagement. The letter cites a delayed release of Claude Mythos Preview, renamed Claude Fable 5, which cost revenue and market share, and about $100 million in free Claude credits for cyber defenders. Anthropic expects more decisions that forgo maximum profit as models get stronger.
