Anthropic uses its IPO letter to renew its pledge that Claude will never show ads

In its IPO filing cover letter, Anthropic restated that Claude will not show ads, saying it wants Claude's only incentive to be giving users a helpful answer and that advertising revenue targets tend to create pressure to optimize for engagement. The company previously criticized rival ChatGPT for running chat ads, warning they could be more manipulative than traditional ads. Anthropic also cited delaying the release of its most powerful model at the time, Claude Mythos Preview, to add safeguards as Claude Fable 5, and giving cyber defenders about $100 million in free Claude credits, as examples of putting values above profit.
