“There are many good places to advertise. A conversation with Claude is not one of them.” This is how Anthropic opens its statement in which, although the company acknowledges the value of advertising, it wishes to make it absolutely clear that the purpose of its AI is not compatible with such activity.
To emphasize its message and make its decision widely known, Anthropic has not only published an official statement, but has also produced a series of videos that are now available for viewing and, additionally, preview its presence at the Superbowl.

The central message of this campaign is “Ads are coming to AI. But not to Claude,” a declaration that has not been received well by Sam Altman. The CEO of OpenAI, a company that recently announced ChatGPT would begin to display advertising, has expressed his displeasure on social networks. But let us take it step by step.
Choosing to accept advertising in Claude would open a new revenue stream for Anthropic, but the company has been clear that it does not wish to compromise its product for this reason. Its current business model generates revenue through enterprise contracts and paid subscriptions, and this is the model it intends to maintain going forward.
Anthropic asserts that Claude must remain a safe and trustworthy space for users in which they may think, explore profound ideas, and accomplish work. According to the company, this vision would be undermined by introducing an advertising business, as it could impact both the operation of the AI model and users’ perception of its reliability.
“We want Claude to act unequivocally in the best interests of our users. That is why we have made a decision: Claude will remain ad-free. Our users will not see ‘sponsored’ links alongside their conversations with Claude; nor will its responses be influenced by advertisers or include third-party advertisements that our users have not requested,” explained Anthropic.
Furthermore, throughout its statement, the AI development company has presented a series of reasons supporting its philosophy, which we have distilled below for your understanding.
Today, everyone has accepted that using a traditional search engine, such as Google, involves encountering sponsored content among all the organic results. This may have shaped expectations regarding the future of AI platforms and led to the assumption that these will inevitably move toward the integration of advertisements.
However, Anthropic believes that, since interaction with AIs differs from how we use search engines, a different approach must be taken when evaluating the inclusion of advertising. In AI assistants, “the format is open; users frequently share context and reveal more than they would in a search query. This openness is part of what makes conversations with AI valuable, but it is also what makes them susceptible to influences to which other digital products are not.”
In addition, the company highlights that a significant portion of users’ conversations with the AI involve sensitive or highly personal topics, for which a trustworthy environment is necessary.
On the other hand, many users turn to Claude to assist them with work-related tasks, approaching the platform as a professional assistant. That is why Anthropic maintains that “the appearance of advertisements in these contexts (personal and professional conversations) would be incongruous and, in many cases, inappropriate.”
Generative AI chatbots represent a relatively new technology, and their impact on users remains under study, with much still to be discovered—both positive and negative. “Preliminary research suggests both benefits—for example, people finding support they otherwise could not access—and risks, including the possibility that the models reinforce harmful beliefs in vulnerable users.”
Given this reality, Anthropic has determined that advertising would further complicate the effects of AI on its users, as it would alter its functioning. “Our understanding of how models translate the goals we assign them into specific behaviors is still developing; therefore, a system based on advertising could yield unpredictable outcomes.”
According to Anthropic, at present, Claude is guided by its commitment to being useful and trustworthy to its users. This purpose could be distorted if the platform were tasked with delivering favorable outcomes for advertisers and placing their ads within relevant conversations.
The company has provided the following example to illustrate its viewpoint: “A user mentions trouble sleeping. An assistant without advertising incentives would explore possible causes (stress, environment, habits, etc.) based on what would be most insightful for the user.
An assistant with advertising would have an additional consideration: whether the conversation presents a transactional opportunity. These objectives often align, but not always. And, unlike a list of search results, ads that influence a model’s responses can make it difficult to determine whether a recommendation serves a commercial purpose. Users should not have to wonder whether AI is truly assisting them or subtly steering the conversation toward something monetizable.”
The placement of advertisements in Claude would ultimately incentivize the optimization of user interaction, shifting the focus toward the amount of time users spend with the AI and how frequently they return. According to Anthropic, “these metrics do not necessarily correspond to genuine utility. The most useful AI interaction could be brief, or it may be the one that resolves the user’s request without generating additional conversation.”
The company recognizes that there are different ways to implement advertising and that not all are comparable, yet it does not believe that the benefits outweigh the potential adverse effects.
“More transparent or voluntary subscription approaches (where users explicitly choose to view sponsored content) could address some of the issues outlined above. Nevertheless, the history of ad-supported products shows that advertising incentives, once introduced, tend to expand over time as they become integrated with revenue goals and product development, blurring boundaries that were previously clearer. We have decided not to introduce these dynamics in Claude.”
The company is dedicated to supporting brands and merchants through other channels, placing special emphasis at present on developing agentic commerce, enabling Claude to perform purchases or make reservations on behalf of the user.
The CEO of OpenAI has turned to his Twitter account to publish a lengthy critique of Anthropic’s position after feeling targeted by their videos.
Sam Altman acknowledged he laughed at the commercials, but this did not keep him from labeling them as dishonest. In his response, he contends that his advertising model diverges from the one Anthropic portrays in its videos: “we would never publish ads as depicted by Anthropic. We are not foolish and we know that our users would reject them.”
First, the good part of the Anthropic ads: they are funny, and I laughed. But I wonder why Anthropic would go for something so clearly dishonest. Our most important principle for ads says that we won’t do exactly this; we would obviously never run ads in the way Anthropic… — Sam Altman (@sama) February 4, 2026

Altman has defended his advertising model by invoking the need to rely on it in order to ensure that ChatGPT can reach more people free of charge or at an affordable price. He believes that Anthropic fails to consider this point, as it “offers an expensive product to affluent individuals”.
He has also taken the opportunity to highlight the supposed difference in user volume between the two AIs: “More Texans use ChatGPT for free than the total number of people using Claude in the United States, so we face a different challenge than they do. (If you wish to subscribe to ChatGPT Plus or Pro, we do not show you ads.)”
In addition, he has accused Anthropic of wanting to control what people do with AI: “they prevent companies they dislike from using their coding product (including us); they want to dictate the rules about what people can and cannot do with AI; and now they also want to tell other companies what their business models may be.”
Finally, Altman sought to contrast Anthropic’s campaign with that of OpenAI for the Super Bowl, emphasizing that his company’s commercial “is about builders and how now anyone can build anything.”
