ChatGPT Ads: What You Can Buy and Whether to Test Them

On August 31, 2026, OpenAI said ChatGPT Ads had reached a $1 billion annualized revenue run rate in less than 200 days after launch, with tens of thousands of advertisers. A few months earlier, one advertiser in the first pilot had managed to spend $2,500 of a $250,000 commitment over four weeks, because the system could not deliver the impressions it had sold, Digiday reported.

Both facts are true, and the distance between them is what you need to understand before putting money into ads inside an AI assistant. This is the practical view: what you can buy inside ChatGPT, how it is priced and measured, what went wrong early, where the other assistants stand, and how to decide whether a test is worth running.

From a $250,000 pilot to self-serve in 63 countries

OpenAI announced in January 2026 that it would put ads in ChatGPT, and began testing them in the US in February, for logged-in adults on the Free and Go plans. Plus, Pro, Business, Enterprise and Education accounts stayed ad-free, and still are. The first phase was invitation-only, priced on impressions, and came with large minimum commitments. Why a company with paying subscribers turned to advertising at all is the subject of why a subscription-funded assistant ended up selling ads.

It did not go smoothly. Advertisers told Digiday that campaigns fell well short of their targeted impressions, that almost nothing happened for close to a month after launch, and that reporting fell short of basic expectations. One agency described the six-figure commitments as “smoke and mirrors in hindsight.” Some large advertisers reportedly said they would not return without a trusted intermediary.

The product then changed quickly. In May 2026, OpenAI opened a self-serve Ads Manager in beta, added cost-per-click bidding alongside impression pricing, and launched a pixel and a Conversions API to track purchases, leads and sign-ups. It named Dentsu, Omnicom, Publicis and WPP as agency partners, and Adobe, Criteo, Kargo, Pacvue and StackAdapt as technology partners. Self-serve buying removed the minimum commitment. Agencies told Digiday that delivery improved, with one reporting fill rates up 30% to 50% from launch levels.

By the end of August, OpenAI said ads were available in more than 40 countries through its sales team and partners, that self-serve buying had expanded to India, Europe, the Middle East and North Africa, and that click-based and outcome-optimized bidding accounted for most campaigns. Its Ads Manager availability page lists 63 countries where a business can buy directly.

What you can actually buy inside ChatGPT

The format is simple. An ad appears below ChatGPT’s answer, labeled as sponsored and visually separate from it. According to OpenAI’s advertiser basics page, each ad carries your name, favicon, a title, a line of copy, an image and a landing page. Product feeds are supported for ecommerce campaigns.

Who sees it is narrower than ChatGPT’s headline audience. Ads run only for Free and Go users. They are not shown to accounts identified as belonging to someone under 18, and they are not eligible near sensitive or regulated topics such as health, mental health or politics. Free users can also choose an ad-free version in exchange for fewer daily messages.

Targeting works differently from search. There are no exact-match keywords. OpenAI runs a relevance-weighted, second-price auction and chooses ads using the context and intent of the current conversation, your landing page, title and copy, and optional “context hints” you supply, which it says “are not exact-match keywords and do not guarantee delivery in specific conversations.” When a user has ad personalization on, broader signals from their ChatGPT use can count too. OpenAI’s August update also lists platform and geographic targeting and custom audiences.

Pricing is an auction on either outcome. Reach campaigns bid a maximum cost per thousand impressions. Click campaigns bid a maximum cost per click, and OpenAI’s own guidance suggests starting at $3 to $5 per click. You can optimize for views, clicks or conversions. Reporting covers impressions, clicks, spend, click-through rate, average cost per click and per thousand, and conversions. Impression and click data refresh about every 15 minutes, while spend can lag by seven to eight hours.

Eligibility is set by where your company is registered, not where your customers are. The legal entity that advertises and is billed must be based in one of the listed countries. At the time of writing, Armenia is not on that list, so an Armenian business cannot use self-serve under its local entity. It can buy through a company registered in an eligible market, or wait.

What the pilot teaches about testing new ad inventory

The common belief about new ad platforms is that early buyers get cheap inventory before the crowd arrives. The original version of this article said as much. ChatGPT’s pilot showed the opposite risk. The first buyers paid for scarce access with large commitments, then waited for a system that could not yet deliver, measure or report properly. The discount went to those who arrived after the self-serve tools, the click bidding and the conversion tracking existed.

That does not mean the inventory is weak. One agency told Digiday that a client’s conversion efficiency on ChatGPT came close to Google non-brand search, though it tracked conversions through URL redirects rather than a proper integration. OpenAI cites an ecommerce advertiser reporting a 3x return on ad spend over 28 days, and a technology partner reporting that more than 80% of its ChatGPT ad traffic came from new customers. Those are case studies chosen by the seller, but they point to the right question: whether the clicks bring people you would not have reached anyway.

The useful lesson is about sequence. Test a new channel when it can measure what you need measured, not when it is newest. For ChatGPT, that point arrived with the pixel, the Conversions API and cost-per-click bidding. Before those, you were paying to learn about OpenAI’s product, not about your customers.

Where the other AI assistants stand

ChatGPT is the only major general-purpose assistant with its own ad platform. The others split three ways.

Google sells ads around AI answers but not inside its assistant app. Ads appear in AI Overviews and are being extended into AI Mode, bought through existing Google Ads campaigns rather than a separate platform. At Google Marketing Live 2026 the company introduced new AI Mode formats, including ads that answer a specific question and sponsored entries within lists of recommendations, plus a Direct Offers pilot that began in January. The Gemini app itself carries no ads. In May, Alphabet’s chief business officer said Google was focusing on the AI Mode format first, with the Gemini app a possible follow-up, as gHacks reported.

Microsoft places ads in Copilot automatically. According to its advertiser documentation, eligible Microsoft Advertising campaigns are opted in by default, advertisers cannot opt out, and there are no Copilot-specific metrics in reporting. You are probably already buying it without being able to see it.

Two assistants have chosen not to sell ads. Perplexity began winding down the ad program it started in 2024, citing concern that ads would make users doubt its answers, Campaign reported in February, a decision covered in why Perplexity walked away from ads. Anthropic said the same month that Claude will remain ad-free. In those assistants, the only way into the answer is to be the source the answer draws on, the work covered in how to get your brand into AI answers without paying for them.

Should you test ChatGPT ads?

Run a test if three things are true. Your company is eligible to buy. You can measure conversions properly, through OpenAI’s pixel or Conversions API or your own backend, rather than trusting platform-reported clicks. And your product is something people research by asking questions: software, travel, considered purchases, services where the buyer needs something explained before choosing.

Skip it, for now, if your sales come mostly from impulse purchases, if your category falls near the sensitive topics where ads are not eligible, or if you cannot yet measure your existing channels well. A new channel will not fix measurement you do not have.

If you do test, treat it like a search ad, not a banner. The ad appears after someone has received an answer, so the copy should continue that answer, saying specifically what you offer for the problem the person was asking about. Start with click bidding, give the test its own budget rather than skimming your best channel, and compare it against Google non-brand search for the same product. Judge it on new customers and real conversions in your own data. Which budget line should fund the test is a decision covered in which search and social budgets get cut to pay for assistant ads, and running it against a proper control is the work of performance marketing that tests new channels against what already works.

Two more things belong in the decision. The first is trust: how people react to ads inside a tool they use to think is still unsettled, a question explored in how users are reacting to ads inside ChatGPT. The second is position. The ad sits below the answer. Whether your brand appears inside the answer is decided by your content and reputation across the web, which is why search engine optimization built for AI answers as well as Google belongs in the same plan as the paid test.

Paid placements in AI assistants are real, measurable and still immature. Test when the measurement is in place, keep the budget separate, and remember that the most valuable position is the one that cannot be bought.

Frequently Asked Questions

How much do ChatGPT ads cost?

ChatGPT ads are sold by auction, either per thousand impressions or per click. OpenAI’s own guidance suggests starting click campaigns at $3 to $5 per click, though actual costs depend on competition for the conversations your ads match. Self-serve buying through Ads Manager has no minimum commitment. That is a change from the early pilot, where advertisers reported minimum commitments of $250,000.

Who sees ads in ChatGPT?

Ads appear only to users on the Free and Go plans. Plus, Pro, Business, Enterprise and Education accounts are ad-free. Ads are not shown to accounts identified as belonging to users under 18, and they are not eligible near sensitive or regulated topics such as health, mental health and politics. Free users can also switch to an ad-free version with fewer daily messages, so the reachable audience is smaller than ChatGPT’s total user base.

Can businesses in Armenia advertise on ChatGPT?

Not through self-serve under an Armenian legal entity, at the time of writing. OpenAI requires the advertising and billing entity to be based in one of the countries on its Ads Manager availability page, and Armenia is not listed. A business with a legal entity registered in an eligible country, such as the United States or an EU member state, can advertise through that entity. Check the availability page before planning, since the list has been expanding.

What are the main challenges of ChatGPT advertising?

The early pilot struggled with underdelivery, high minimum commitments and weak reporting. Delivery and tools have improved, but challenges remain. Targeting uses conversation context and optional hints rather than exact keywords, so control is looser than in search. The audience is limited to Free and Go users. Many sensitive categories are excluded. And measurement depends on installing the pixel or Conversions API, without which results are hard to trust.

Do ads change ChatGPT’s answers?

OpenAI says they do not. Its stated principles are that ads are clearly labeled, kept separate from answers, and do not influence what ChatGPT says, and that advertisers receive only aggregated performance data, not conversations or personal details. Ads are selected using the context of the conversation, and, if a user has ad personalization turned on, broader signals from their ChatGPT use. Users can see why an ad was shown and manage personalization settings.
