Anthropic reaffirmed in its S-1 IPO prospectus that Claude will never carry advertisements, framing the commitment as a core value principle. The company stated that integrating ads into revenue targets would create pressure to optimize user engagement over providing genuinely useful answers, placing this stance in the category of "values before profits." The filing also highlighted Anthropic's safety-first approach, citing the delayed release of Claude Mythos Preview—which carried higher cyberattack risk—before launching the safer Claude Fable 5 model, a decision that cost the company revenue and market share. Additionally, Anthropic has provided network defenders with approximately $100 million in free Claude credits. The company had previously criticized ChatGPT for introducing ads into chat interactions.
