PHYSIX OBSERVATION

Chatbot advertising has moved from experiment to scale, with OpenAI and Google leading the way, while Anthropic is using its massive funding to stay ad-free, creating a split in strategy. Advertisers are not yet satisfied with performance; AI-generated creative and precise targeting via conversation context are the bright spots, but privacy trade-offs and brand compliance risks remain hidden hazards. For users, the price of free AI may soon be ads.
