Anthropic Pledges Claude Will Remain Ad-Free as ChatGPT and Google Expand Ads

What Happened

• Anthropic has maintained a pledge to keep its Claude chatbot ad-free, a commitment made during a Super Bowl commercial [1, 2].
• OpenAI has introduced ads to ChatGPT, with over 100,000 customers advertising on the platform since ads debuted in February [1].
• Google has expanded ads in its search chatbot AI Mode to 10 additional countries beyond the United States [1].
• Microsoft Copilot features ads that are intentionally designed to appear below responses with explanations of their relevance [2].
• Meta AI currently does not have ads in chats, but the company uses AI interactions to target ads across its wider platform [2].
• Koah Labs, a San Francisco startup, markets ad technology to over 200 apps, including DeepAI and Liner [1].

OpenAI CEO Sam Altman responded to criticisms regarding ad integration by stating that more Texans use ChatGPT for free than the total number of Claude users in the US [2]. He described Anthropic’s depiction of ads as deceptive, asserting that ChatGPT ads are labeled, separate from answers, and do not influence model responses [2].

Koah Labs CEO Nic Baird reported that ads partially composed by AI generate double the clicks compared to fully human-made ads [1]. He noted that Koah’s ads are grounded in advertiser-supplied details to avoid AI hallucinations, though he observed that companies like drugmakers often use more human control due to government regulations, which can lead to weaker results [1]. Koah reports a click rate of approximately 3 percent, which is similar to the performance of Google’s established ad system [1].

Anthropic stated that advertising in chats can feel inappropriate because users often engage in sensitive topics or complex thinking [2]. While the company plans to support commerce through user-initiated features like agentic commerce—where Claude helps with purchases or bookings—it intends to do so only when users choose to engage [2].

Who Is Affected

• Developers and niche chatbot platforms may rely on advertising to manage the high costs of generating AI responses [1].
• Advertisers, including brands like Hims and UrbanStems, use services like Koah Labs to reach users [1].
• Users of ChatGPT, Google AI Mode, and Microsoft Copilot will encounter advertisements within their chat experiences [1, 2].
• Companies in regulated sectors, such as drugmakers, face specific challenges in using AI-generated marketing copy [1].
