For over two decades, digital marketers have operated with a shared safety net: visibility. In the world of search engine marketing (SEM), tools like Google’s Auction Insights have long provided search teams with a rear-view mirror. Even if you were losing ground to a competitor, you could see who they were, analyze their ad copy, estimate their impression share, and adjust your bidding strategies accordingly. You knew the battlefield because the battlefield was public.
But a quiet revolution has taken place. Conversational AI has introduced an entirely new advertising medium, and with it, a massive competitive blind spot. Brands are actively bidding on, winning, and scaling campaigns inside ChatGPT. Yet, unlike traditional search engine results pages (SERPs), there is no native transparency. You cannot easily see who your competitors are, what prompts they are targeting, what their ad creative looks like, or how often they are showing up instead of you.
This lack of visibility represents one of the most significant strategic challenges search teams have faced in years. Earlier in 2026, OpenAI officially launched advertising directly inside AI-generated responses. Major brands immediately recognized the opportunity, flooding the channel within weeks. The entry barrier dropped, the native Ads Manager was established, and a brand-new performance marketing channel was born. As ChatGPT ads prepare to roll out in the U.K. and other international markets, the window for early-mover advantage is closing quickly. To succeed, marketers must understand what the data reveals about this rapidly maturing landscape.
The State of ChatGPT Ads: A Deep Dive into the Data
To understand exactly how this new ecosystem is behaving, search intelligence platform Adthena conducted a comprehensive study. Between March 2026 and May 2026, Adthena analyzed nearly 1 million query indexes across 20 distinct industries and five major global markets: the United States, the United Kingdom, Australia, New Zealand, and Canada.
The findings paint a picture of a channel that is highly concentrated, intensely competitive in specific niches, and structured in a way that fundamentally changes the rules of modern paid search.
The Geographic Landscape: A U.S.-First Channel
The data shows that ChatGPT’s ad network is currently heavily centered in North America, while other regions are in various stages of preparation or early testing.
- The United States: ChatGPT served ads on approximately 4.47% of all analyzed queries. The U.S. remains the primary engine of the platform’s ad revenue, accounting for roughly 90% of all ad placements observed in the dataset.
- Canada: Leads the dataset slightly in terms of frequency, with ads appearing on 4.57% of queries.
- New Zealand: Showing healthy early adoption, with an ad frequency of 3.85%.
- Australia: Hovering at a modest 1.61% ad frequency as the market begins to scale.
- The United Kingdom: Across approximately 170,000 U.K. query indexes monitored during this period, zero ads were detected.
For search teams based in the U.K. and other pre-launch markets, this geographic disparity is a double-edged sword. On one hand, the channel is not yet live locally, meaning there is no immediate budget pressure. On the other hand, global competitors operating in the U.S. have had months of hands-on experience. They have already identified high-converting prompts, refined their conversational ad copy, and established baseline conversion metrics. When OpenAI flips the switch in the U.K., these international players will enter the auction with a massive operational head start. Local brands cannot afford to wait for the launch to begin planning their strategy.
The Winner-Take-All Bidding Dynamic
Perhaps the most critical structural difference between Google Ads and ChatGPT Ads is the number of available ad slots. On a standard search engine results page, multiple advertisers can co-exist. You can occupy position two, three, or four, adjust your bids to manage your cost-per-click (CPC), and still capture a highly profitable stream of transactional traffic.
On ChatGPT, the real estate is aggressively restricted. The data reveals that in the U.S., ChatGPT averages just 1.06 ad items per ad-bearing response. In the vast majority of cases, when an ad appears, it is a single, isolated sponsored placement integrated directly into the conversational output. There are no sidebars, no bottom-of-page blocks, and very few carousels.
This layout transforms conversational advertising into a binary, winner-take-all game. Your brand is either the recommended solution within the AI’s response, or it does not exist in that interaction. This shifts the strategic importance of Share of Voice (SoV) from a directional optimization metric to an absolute survival metric.
Which Industries Are Dominating the Conversational Space?
The distribution of ads across different verticals shows that certain sectors have adapted to the conversational format far more rapidly than others. While the overall platform average for ad frequency sits at roughly 3.3% across all markets, several key industries are dramatically over-indexing.
The Hottest Categories on ChatGPT
Contrary to what some might expect, highly technical or B2B software categories are not leading the charge. Instead, practical, consumer-focused, and service-oriented sectors are seeing the highest ad frequencies:
- Logistics: Tops the list with a striking 12.41% ad frequency. Conversational queries regarding shipping, moving, tracking, and supply chain solutions are highly commercial, and advertisers are bidding aggressively to meet that intent.
- Home & Garden: Follows closely at 11.99%. Users frequently ask ChatGPT for step-by-step DIY advice, product recommendations for home improvement, or design ideas, creating the perfect context for native ad integrations.
- Beauty & Cosmetics: Registers a 10.03% ad frequency. This is a category driven by product discovery, routine recommendations, and ingredient comparisons, making conversational recommendations highly persuasive.
- Media & Entertainment: Shows strong adoption at 8.00%.
- Insurance: Stands at 7.20%, capturing users looking to compare policies or understand complex coverage terms.
- Energy & Utilities: Records a 6.40% ad frequency.
Retail & Fashion: The Volume Leader
While logistics and home improvement boast the highest ad frequencies per query, Retail & Fashion is where the absolute volume of advertising investment is concentrated.
In the U.S. market, Retail & Fashion queries represent 24.1% of the total query volume analyzed. However, the vertical accounts for a massive 38.9% of all U.S. ad items served. With an individual category ad frequency of 6.55% (significantly higher than the 4.47% U.S. average), retail brands are actively engaged in a high-stakes battle for presence inside AI recommendation cycles. The sector represents more than a third of all ad placements across the entire global dataset, proving that e-commerce and conversational search are deeply intertwined.
The Blocked Verticals: A Strategic Pause
Interestingly, the study identified four major categories that returned exactly zero ads across the entire multi-market dataset: Legal, Pharma, Banking, and Nonprofits. Healthcare was also near-zero, recording a tiny ad frequency of just 0.45%.
This zero-run is almost certainly the result of deliberate policy safety measures implemented by OpenAI, rather than a lack of commercial interest from advertisers. Given the high-risk nature of “Your Money or Your Life” (YMYL) topics, OpenAI appears to be taking a highly cautious approach to serving sponsored recommendations in spaces where incorrect information or biased advice could have legal, financial, or medical consequences.
However, these restrictions will inevitably evolve. As regulatory frameworks clarify and AI accuracy improves, these blocked categories will open up. The financial and legal brands that are already monitoring the landscape today will be the ones positioned to launch campaigns the moment the gates are opened.
The Analytics Blind Spot: Marketers Operating in the Dark
For search engine marketers accustomed to granular data, the current reporting capabilities of OpenAI’s native Ads Manager can be incredibly frustrating.
The native tool provides internal campaign performance metrics:
- Total spend
- Impressions
- Clicks
- Average CPC (Cost Per Click)
- CTR (Click-Through Rate)
While this is useful for basic ROI calculations, it completely omits the external market context. It does not show you:
- Which of your direct competitors are targeting the same prompts.
- What conversational variations or user prompts are triggering your competitors’ ads versus your own.
- The ad creative, messaging, and offers your competitors are running.
- Your overall Share of Voice across specific commercial topic clusters.
Because ChatGPT only serves a single ad per response in most cases, bidding blindly without competitor intelligence is incredibly risky. You could be overbidding on uncontested prompts, or completely locked out of high-intent queries by a competitor whose strategies and spend remain totally invisible to you.
Shining a Light on Conversational Search with Adthena
To bridge this critical information gap, Adthena developed ChatGPT Ads Intelligence.
By monitoring over 300,000 prompts daily across active advertising markets, the platform provides the comprehensive, whole-market view that search marketers need. This tool brings the exact same rigorous, data-driven competitive intelligence that made Adthena a leader in Google search monitoring, and applies it directly to the conversational AI space.
Through the platform, marketing teams can:
- Identify which specific competitors are bidding on high-value prompt clusters.
- Track and analyze weekly Share of Voice trends compared to top competitors.
- Examine the messaging, positioning, and call-to-actions being utilized by rivals.
- Uncover “Greenfield” prompts—valuable, high-intent user queries where no advertisers are currently displaying ads, offering a low-cost opportunity to capture uncontested traffic.
In a newly forming ad channel where bidding behaviors have not yet ossified, finding these greenfield opportunities can yield massive returns. However, this open window of opportunity is temporary; as more brands adopt conversational search strategies, these gaps will close.

The Broader Impact: The Decentralization of Search
This shift goes far beyond ChatGPT. Traditional search is no longer the sole gateway to the internet. Consumers are increasingly bypassing traditional search engines entirely, opting to use AI-native, conversational interfaces like ChatGPT and Perplexity for complex, multi-step search journeys.
Whether looking for a detailed itinerary for a trip to Italy, trying to diagnose a weird sound coming from a dishwasher, or comparing the best enterprise CRM options, users are asking tools to synthesize information rather than returning a list of links. The intent behind these queries is incredibly high, and the advertising dollars are naturally following where the attention is shifting.
As a search practitioner, your mandate is expanding. The exact same discipline, monitoring, and strategic optimization you apply to traditional search engines must now be applied to conversational AI touchpoints. The brands that establish their presence, secure their share of voice, and master conversational bidding now will build a competitive moat that will be incredibly difficult to disrupt as the market continues to mature.
The early days of Google AdWords rewarded the pioneers who figured out the platform before it became crowded and expensive. We are watching the exact same story play out today with conversational ads. The data shows the opportunity is real, and the tools are now available to help you claim your share.
