OpenAI walked into Cannes Lions this week and, for the first time in its history, said out loud: "We are an advertising business." That declaration — made by Chief Revenue Officer Denise Dresser on the French Riviera — landed at the same festival where Google and Meta have dominated the media-buying conversation for a decade, and it changes the three-platform math that every service business owner uses when they plan a paid campaign. If you run Google Ads, buy Meta leads, or have been watching ChatGPT steal your prospects' attention, this story is directly about your budget.
OpenAI did not just show up at Cannes Lions for the press. It showed up with a four-month-old ad product, a self-serve platform already open to U.S. small and medium-sized businesses, and an eye-popping revenue target: $100 billion in annual advertising revenue by 2030.
According to reporting from Semafor, Analytics Insight, and Digital Applied — all covering the Cannes Lions week of June 22, 2026 — OpenAI's Chief Revenue Officer Denise Dresser told assembled brands and agencies the company is "clearly in the advertising business now," the first time OpenAI has owned that label publicly at a major industry event. ChatGPT ads launched in February 2026 for users on the free and "Go" subscription tiers, appearing as clearly marked sponsored content below AI-generated responses. By the time Cannes opened, OpenAI already had thousands of advertisers across seven test markets: the U.S., Canada, the U.K., Australia, New Zealand, Japan, and South Korea. According to Adgully's coverage, plans to expand into Brazil, Mexico, and eventually India are in motion.
The revenue projections are staggering — and worth scrutinizing. According to projections reported by Axios and corroborated by eMarketer and covered by Digital Applied, OpenAI is forecasting roughly $2.5 billion in ad revenue in 2026, scaling to $11 billion in 2027, $25 billion in 2028, and approximately $100 billion by 2030. Those are vendor-stated investor projections, not audited figures. As Digital Applied noted pointedly, the $100 billion target assumes ChatGPT reaches roughly 2.75 billion weekly users by 2030 — more than triple today's reported base. The revenue projection is really a user-growth projection wearing a revenue headline.
But even at $2.5 billion this year, ChatGPT is already one of the fastest-growing ad platforms in digital history. For context: AdExchanger noted at Cannes that Meta — founded in 2004 — took approximately 17 years to build a $100 billion ad business.
OpenAI's Cannes pitch was not aimed at packaged-goods brands or Fortune 500 advertisers first. The platform's strongest early verticals tell a different story.
According to BeInCrypto's coverage of the Cannes event, David Dugan — OpenAI's global head of ads and a former Meta vice president — told reporters that roughly 20% of ChatGPT queries carry direct commercial intent, with travel, retail, health, beauty, and financial services performing best so far. Read that list carefully: health and beauty (med spas, dentists, dermatologists), financial services (financial advisors, accountants, insurance agents), and travel-adjacent bookings (hospitality, real estate) are core service-business categories.
OpenAI's self-serve advertising platform — now live in the U.S. and other English-speaking markets — allows small and medium-sized businesses to purchase ChatGPT ad campaigns directly, without a sales rep or a minimum spend. According to Social Samosa's coverage of the Cannes announcement, this self-serve expansion is a deliberate move to compete with Google's and Meta's long-established SMB pipelines.
The core pitch OpenAI is making to planners, as covered by Storyboard18 and Let's Data Science, is what they call "super-intentional" users. When someone opens ChatGPT and types "find me a financial advisor near me who specializes in small business retirement planning," they are not browsing — they are actively in a decision process. That is a different user than a Facebook scroll or even a Google keyword search. OpenAI's ads head Dugan framed it to Cannes reporters as users who "come to the app with a job to be done."
The Cannes reception was cool, and you should know why before you open your wallet.
Senior advertising executives at Cannes pushed back hard. As BeInCrypto reported, several told the Financial Times that OpenAI needs more sophisticated targeting and measurement tools before it can realistically challenge Google's grip on performance advertising budgets.
Digital Applied's analysis was the most direct: ChatGPT ads still lack the standardized viewability metrics, independent audience verification, and mature cross-channel attribution that regulated advertisers (financial advisors, healthcare providers, real estate agents) need to justify budget allocation at scale. A plumber cannot easily prove that a ChatGPT ad drove a booked HVAC installation the way they can in Google Ads with conversion tracking. Not yet.
Here is a realistic comparison of where the three platforms stand right now for service businesses:
The honest position: ChatGPT ads are worth a test budget in 2026, not a budget reallocation. The intent signal is genuinely interesting. The measurement infrastructure is not ready for you to fly blind on it.
The reason this story matters beyond ChatGPT is what it does to the competitive dynamics of the other two platforms you already use.
OpenAI's Cannes declaration signals that Google and Meta will face real pressure for ad dollars from a third major platform within the next two to three years. That pressure tends to produce one outcome that benefits small advertisers: it forces incumbents to improve their products and reduce their cut. Google is already navigating the fragmentation of search into AI Overviews and AI Mode. Meta is projecting $243 billion in 2026 ad revenue — beating Google for the first time in digital advertising history, according to eMarketer data — and leaning hard into Advantage+ automation to maintain that lead.
For a service business owner running $2,000–$10,000 per month in paid media, the practical upshot is this: the ad market is becoming more competitive, which historically means CPMs (cost per thousand impressions) on individual platforms face downward pressure over time as supply grows. More platforms competing for the same dollars is not a bad thing for the buyer.
But fragmentation also creates a new risk. If your competitor tests ChatGPT ads and captures the "financial planner near me" query before you do, they own that intent surface while you are still running the same Google Search campaign from 2024. First-mover advantage on new ad surfaces is real — Google Ads early adopters in 2003 and Facebook advertisers in 2010 both benefited from dramatically lower CPCs before the market caught up.
The mechanics matter. Here is what the ChatGPT advertising product looks like in practice, based on reporting from Analytics Insight, Adgully, and Let's Data Science:
What OpenAI has not disclosed publicly: minimum spend thresholds, CPC or CPM benchmarks, and detailed conversion attribution pathways. Until those are available, treat this as an experimental channel.
You do not need to drop everything and overhaul your ad budget. But you do need to make a few concrete moves before your competitors do.
1. Claim your spot on the self-serve waitlist or platform now. Go to OpenAI's advertising platform and create an account. Even if you do not run a single ad this month, getting your business verified and your brand profile set up puts you ahead of the queue as the product matures.
2. Run a $500–$1,000 test on your highest-intent service category. If you are a financial advisor, test a campaign targeting queries like "financial planner for small business owners" or "retirement planning for self-employed." If you are a med spa, test "lip filler near me" or "Botox consultation." The cost to learn is low; the cost of being late is higher.
3. Do not redirect existing Google or Meta budget. Add ChatGPT ads as an incremental test budget, not a swap. You cannot attribute results yet with the same confidence as your existing channels. Until independent measurement firms confirm conversion quality, this is top-of-funnel discovery spend, not bottom-funnel lead gen.
4. Audit your ChatGPT brand presence before you advertise. When users ask ChatGPT about your service category, what does the AI say? If you have not checked, check now. Your organic brand reputation inside ChatGPT's training data and real-time browsing determines what users see around your ads. A bad organic presence next to a paid placement is a wasted impression.
5. Set a calendar reminder for Q4 2026 review. By October, independent measurement firms will likely have published early attribution data on ChatGPT ad conversions. That is when the buy/don't-buy decision becomes data-driven rather than directional. Build the review into your media planning cycle now.

What are ChatGPT ads and how are they different from Google Search ads?
ChatGPT ads are contextual sponsored placements that appear below AI-generated responses inside ChatGPT conversations. Unlike Google Search ads, which target specific keywords a user types into a search bar, ChatGPT ads target users based on the real-time intent and topic of their ongoing conversation — no keyword bidding or cookie-based tracking is required. The result is a different kind of intent signal: longer-form, research-stage queries rather than short transactional searches.
Can any service business buy ChatGPT ads right now?
Yes, in theory. OpenAI launched a self-serve advertising platform in the U.S. and other English-speaking markets that allows small and medium-sized businesses to purchase campaigns directly. However, the platform is still in its early stages — minimum spend thresholds, detailed targeting options, and conversion attribution tools are not yet at the maturity level of Google Ads or Meta Ads Manager. Expect a significant product roadmap over the next 12–18 months.
Should I move my Google Ads budget to ChatGPT ads?
Not yet. ChatGPT ads currently lack the standardized attribution, independent audience verification, and brand-safety controls that most performance advertisers need to justify large budget moves. The right approach is to treat ChatGPT ads as an incremental test budget — $500 to $1,000 to learn — while keeping your existing Google and Meta spend intact until there is published third-party data on conversion quality.
Which service business categories should pay closest attention to ChatGPT ads?
According to OpenAI's own data shared at Cannes Lions, the strongest early verticals are financial services (financial advisors, accountants, insurance agents), health and beauty (med spas, dentists, dermatologists), and travel-adjacent services (hospitality, real estate, vacation rentals). If your business falls into one of these categories, the intent match is strong enough that a test is worth prioritizing sooner rather than later.
Is the $100 billion ad revenue target by 2030 realistic?
It is ambitious, not impossible — but it rests on assumptions that deserve scrutiny. The $100 billion figure assumes ChatGPT reaches roughly 2.75 billion weekly users by 2030, more than triple today's reported base of approximately 1 billion weekly users. For comparison, Meta took about 17 years from founding to reach a $100 billion ad business. OpenAI has four months of ad revenue history. The projection matters for the industry as a signal of intent; it matters much less as a financial forecast.
