Anthropic reiterates in IPO letter that Claude will not run ads
In its IPO filing cover letter Anthropic again pledged that its Claude chatbot will not show advertising, saying ads would introduce engagement-driven incentives that conflict with giving helpful answers. The company also highlighted past choices prioritizing safety and values over profit — delaying the release of its most capable model (previously called Claude Mythos Preview / later Claude Fable 5) and providing roughly $100 million in free credits to cyber defenders — as examples of foregoing revenue.
