Anthropic reiterates commitment in IPO filing letter: Claude will never show ads

In its IPO filing letter, Anthropic reiterated that it will not introduce ads into Claude chat, saying that once advertising becomes a revenue goal, the pressure to optimize engagement tends to grow. The letter also mentioned that at the time its strongest model, Claude Mythos Preview, was delayed for release as Claude Fable 5 with additional safeguards added due to high risk from advanced cyber capabilities, costing revenue and market share, and that it provided about $100 million in free Claude credits to cyber defenders. Anthropic had previously criticized ChatGPT for placing ads in chat and expects to make more decisions forgoing maximum profit in the future.
