OpenAI to test ads inside ChatGPT for free and Go users in the US

• What happened: OpenAI confirmed it will test ads inside ChatGPT for select users in the United States in the coming weeks.
• Why it matters now: The company is seeking new revenue streams to support rising AI infrastructure costs.
• What changes for people: Free and Go plan users will start seeing ads, while paid tiers remain ad-free.
• Who is affected: Students, developers, casual users and professionals relying on ChatGPT Free and Go tiers.

OpenAI will begin experimenting with advertising inside ChatGPT, marking its most significant monetization shift since the chatbot launched. The company said the tests will initially apply only to users on the Free tier and the lower-cost Go plan, which is now expanding globally. Ads are expected to appear in the United States within weeks.

The move signals a strategic pivot as the AI developer faces surging compute and data center expenses and prepares for a potential stock market debut. For OpenAI, sustainable revenue is becoming a priority as adoption accelerates across consumer and enterprise use cases.

How the ads will work

OpenAI stated that ads will be separate from ChatGPT’s generated responses and appear after answers, not inside them. The company also underlined that:

• User conversations will not be shared with advertisers
• Ads will not influence ChatGPT outputs
• Users under 18 will not see ads
• Ads will be blocked from sensitive categories such as health and politics

Users subscribed to Plus, Pro, Business and Enterprise plans will continue using ChatGPT without advertising.

Why the business model is changing

OpenAI has traditionally relied on subscriptions, but maintaining cutting-edge AI models requires enormous computing budgets. Analysts note that the company is facing industry-wide pressure to commercialize, especially as it scales infrastructure and pursues multibillion-dollar data center investments.

Industry researchers estimate that ChatGPT has hundreds of millions of active users, making the free tier a potentially massive advertising channel. At the same time, analysts warn that intrusive or irrelevant advertising could push users toward competing AI chatbots.

Marketing analyst Jeremy Goldman said the shift could prompt rivals like Google Gemini and Anthropic Claude to clarify whether they will adopt ads or remain subscription-first.

What it means for users and the AI market

For free users, the update reflects a trade-off: continued access to powerful AI tools without subscription fees, but now supported by sponsored placements.

For the AI ecosystem, the move illustrates a broader trend where generative AI platforms are evolving beyond research labs into scaled consumer businesses with clear revenue models.

OpenAI is also expanding its ChatGPT Go offering into the United States at 8 dollars per month, targeting light professional and educational use.
