Should Your Business Advertise on ChatGPT? Our Take for 2026
It's too early to set a budget, the decision-maker audience is too small for most B2B companies, and the real potential is in urgent consumer moments. Here's how that plays out for professional services, manufacturers, retailers, and consumer brands.
Our take on ChatGPT ads is simple. It's too early to set a budget, the decision-maker audience is too small for most B2B companies, and the real potential is in urgent consumer moments. We're waiting for bigger companies with bigger budgets to test it first, and we'll share what they learn.
This applies across the board: law firms, accounting firms, and other professional services, plus manufacturers, retailers, and consumer brands. Here's how it breaks down for each.
What You'll Learn
- Only Free and Go users see ChatGPT ads, which narrows who you can reach.
- OpenAI says it doesn't have performance benchmarks yet, so budgets are guesswork.
- Most B2B buyers and decision-makers are on plans that never see ads.
- Law, accounting, and healthcare face extra rules, and some can't advertise at all.
- "Buy now" and "what do I do when" questions are where ads could eventually pay off.
- Ad formats keep changing, so long-term plans are risky.
- Earning a spot in ChatGPT's answers matters more for most businesses today.
How Do ChatGPT Ads Work Today?
ChatGPT ads show up below an answer, labeled as sponsored. OpenAI started showing them in the U.S. on February 9, 2026, and opened self-serve buying in May. You don't bid on keywords. Instead, you give OpenAI hints about the kinds of conversations your ad fits, and its system decides when to show it.
The audience is narrower than ChatGPT's headline user numbers suggest. According to OpenAI's help center:
- Only logged-in adults on the Free and Go plans see ads.
- Plus, Pro, Business, Enterprise, and Edu accounts never see ads.
- Temporary Chats show no ads.
- Ads are kept away from health, mental health, and political conversations.
OpenAI's ad policy also limits who can advertise. Consumer categories like household goods, local services, travel, and digital products were first in line. Financial, health, and legal advertisers go through extra review, and some categories, like alcohol and gambling, aren't allowed at all.
Why It's Too Early to Set a ChatGPT Ad Budget
Nobody knows yet what good performance looks like. OpenAI has said it doesn't have performance benchmarks across advertisers, industries, or campaign types. Without those, there's no way to plan a budget the way you would for Google or Meta.
The early results that are public are all over the place. Search Engine Journal rounded up several in September:
- Hostinger spent nearly $70,000 testing and found click-through rates and traffic quality were the main problems.
- An online retailer with high-priced products reported 3.3x to 6.8x return on ad spend, depending on how sales were credited.
- Click costs ran from under $3 to over $20, depending on the advertiser and the country.
OpenAI has shared some good news too. It says WeightWatchers saw a cost per acquisition about 15% lower than its paid search benchmark, as measured by a partner. That's encouraging, but it's one large brand with a big budget, reported by the platform selling the ads.
Big brands like these can afford to spend and learn. Most small and midsize businesses can't. We'd rather let them find out what works and then bring those lessons to our clients.
B2B Companies and Manufacturers: Too Few Decision-Makers in the Audience
For most B2B companies, the people who sign purchase orders aren't seeing these ads. Engineers, plant managers, procurement leads, and executives often use ChatGPT through a company Business or Enterprise plan. Others pay for Plus. None of those plans show ads.
An advertiser spent about $7,000 CAD and traced 336 paid clicks to 146 organizations. Only five matched its ideal customer profile, according to Search Engine Journal. That's a single test, but it lines up with how the plans are built.
B2B buying is also slow. A manufacturer choosing a new supplier or a component spec compares options over weeks or months, with several people involved. A sponsored link under one chat answer rarely moves that kind of decision.
An exception worth watching: the engineer doing research
There's one industrial use case we think is worth watching. An engineer asks ChatGPT why a pump keeps cavitating, how a process works, or how to fix a recurring problem on the line. Not every engineer is on a company plan, and some use a free personal account for quick technical questions.
An ad under that answer could link to a product video or technical explainer on your site showing how your solution works. The engineer may not sign the purchase order, but engineers often research options and bring them to the people who do.
Success would look like video views, time on site, and return visits, not form fills. It's still too early to budget for, but it's the B2B scenario we'll watch most closely.
Where B2B companies should pay attention is the answer itself. When an engineer asks ChatGPT for suppliers of a specific part or material, the companies named in the response earned that spot through their websites and content. That's where we'd focus.
Professional Services: Law, Accounting, and Other Advisory Firms
Professional services firms face the same audience problem as B2B, plus extra rules. Some can advertise now, some only with special approval, and some mostly can't.
| Industry | Can they advertise on ChatGPT? | Where it might work |
|---|---|---|
| Law firms | Yes in the U.S. since Aug 31, 2026, if licensed where the ad runs, after manual review | Personal injury, criminal defense, immigration, landlord-tenant |
| Accounting and tax firms | Financial services is restricted and reviewed case by case; accounting isn't named in the policy | Individual tax help in filing season, like IRS letters and extensions |
| Medical and dental practices | Clinical care ads are largely not allowed, and ads stay away from health conversations | Very little today |
| Consulting, engineering, architecture, IT services | No special restriction | Limited, since clients are mostly business decision-makers |
The same split shows up in every one of these fields. The business side of the work, like corporate law, audits, or consulting engagements, is sold to people on paid or company plans who don't see ads. The consumer side, like a car accident or a letter from the IRS, is where an urgent "what do I do" question meets the free-tier audience.
Professional rules still apply, too. OpenAI checks that you're a real, licensed business, but it doesn't check your ad against your state bar's advertising rules or your board of accountancy's standards. That review stays with your firm.
Retail and Consumer Services: "Buy Now" and "What Do I Do When" Moments
Consumer businesses are the better fit, especially when someone needs to act fast. We see two kinds of questions where ChatGPT ads could eventually earn their keep.
"Buy now" questions
Someone asks which space heater to get before tonight's cold snap, or where to find a specific coffee blend. They're ready to purchase, and a well-matched product ad lands at the right moment.
"What do I do when" questions
Someone's basement is flooding, their furnace quit in January, or their car got towed. They need a local service now, not next week.
Both fit the people who actually see these ads: everyday consumers on the free app, often on their phones, trying to solve a problem. Local service businesses, retailers, and ecommerce brands are also in the categories OpenAI opened first.
We say "eventually" on purpose. Even in these categories, results so far are mixed, and smaller businesses don't have the data to know what a fair cost per sale or lead looks like. The opportunity is real, but the playbook isn't written yet.
What Does OpenAI's Research Say About How People Use ChatGPT?
OpenAI's own research supports the consumer angle. In How People Use ChatGPT, published in September 2025, researchers from OpenAI and Harvard studied about 1.1 million conversations on consumer plans.
- About 73% of messages were not related to work by June 2025, up from 53% a year earlier.
- Nearly half of messages were people asking for information or advice to help make a decision.
- Nearly 80% of conversations were practical guidance, seeking information, or writing.
- Users in professional jobs were more likely to use ChatGPT for work.
The study also left out Business and Enterprise accounts. The authors note that many corporate users work in those plans, which matches the B2B problem above.
The data ends in mid-2025, before ads launched, and it mixes free and paid users. It's a helpful signal about behavior, not a profile of the ad audience.
ChatGPT Ad Formats Keep Changing
Any plan built on today's ad format may be out of date by spring. Here's how much has changed in 2026 alone:
| Date | What changed |
|---|---|
| Oct 26, 2026 | Multi-image ads open as a beta in Ads Manager |
| Oct 5, 2026 | Visual ads during image generation announced, with U.S. testing later in October |
| Aug 31, 2026 | Self-serve Ads Manager reaches 52 countries |
| May 5, 2026 | Self-serve Ads Manager opens in beta with cost-per-click bidding |
| Feb 9, 2026 | Ads go live below answers for U.S. Free and Go users |
Ads Manager is still labeled beta. Reporting is still basic, with no competitive data showing who you're bidding against. Those gaps will likely close, but they make it hard to judge a campaign today.
What We're Doing About ChatGPT Ads
We're watching, not spending, for now. Large brands with big budgets are already testing ChatGPT ads, and they can afford to spend money just to learn. Once they publish clear results by industry and campaign type, we'll know a lot more about what's worth trying.
In the meantime, here's where we're putting our clients' effort:
- Show up in the answer. Ads sit below ChatGPT's response and don't change it, according to OpenAI. Every user sees the answer, including paid users who never see ads.
- Track AI traffic now. Make sure your analytics separate visits from ChatGPT and other AI tools, so you have a baseline before you ever buy an ad.
- Build the landing pages first. If ads do make sense later, you'll need fast, specific pages for the urgent questions your customers ask.
- Revisit every quarter. Formats, policies, and benchmarks are all moving. We'll update our view as they do.

Frequently Asked Questions About ChatGPT Ads
Should my business advertise on ChatGPT right now?
For most businesses, not yet. There are no benchmarks to plan a budget around. We suggest waiting for results from larger advertisers.
Do ChatGPT ads work for B2B companies?
For direct leads, rarely so far. Most business decision-makers use paid or company plans that never show ads. There may be an awareness play with engineers researching how products and processes work.
Which businesses are the best fit for ChatGPT ads?
Consumer businesses that answer urgent needs. Think retailers with "buy now" products and local services people need right away.
Can law firms and accounting firms advertise on ChatGPT?
Law firms can in the U.S., if they're licensed where the ad runs and pass OpenAI's review. Accounting firms fall under financial services, a restricted category that OpenAI reviews case by case.
Do ChatGPT ads affect what ChatGPT recommends?
OpenAI says no. Ads are labeled and kept separate from the answer. Getting named in the answer depends on your website and content.
