OpenAI Launches Product Carousels in ChatGPT, Expanding Ecommerce Ad Format
OpenAI introduces product carousels to ChatGPT ads, allowing multiple products to appear in a single ad placement — a significant step toward full shopping integration.
OpenAI's Carousel Format Changes the ChatGPT Ad Game
OpenAI has introduced product carousels to its ChatGPT advertising platform, allowing multiple products from a single retailer to appear side-by-side within a conversation. The format represents a significant evolution from the single-product ads that previously appeared at the bottom of ChatGPT responses, and signals OpenAI's ambition to build a full-featured ecommerce advertising channel.
The carousel format pulls product data from merchant feeds—similar to how Google Shopping operates—enabling visually rich product cards with images, prices, and key attributes to display horizontally within the chat interface. Users can scroll through options without leaving the conversation, creating a shopping experience that feels native to the AI assistant.
Key details
- Carousel format shows multiple products from one retailer in a single ad placement
- OpenAI controls whether to show single product or carousel—advertisers cannot choose
- Product data pulled from merchant feeds, similar to Google Shopping
- Rolling out ahead of Q4 holiday shopping season
- OpenAI targeting $2.5 billion in ad revenue for 2026
How the Carousel Ad Format Works
Previously, ChatGPT displayed single product advertisements at the bottom of conversations when users asked product-related questions. A user asking "What's a good blender for smoothies?" might see one sponsored product card. The new carousel format allows that same query to surface a horizontally scrollable row of multiple blenders from the same retailer, each with its own image, price, rating, and purchase link.
Critically, the decision of whether to show a single product or a carousel is made by OpenAI's systems, not by the advertiser. The AI evaluates the user's query intent and determines which format best serves the response. This means merchants cannot force carousel display—they can only ensure their product feeds are comprehensive enough to qualify.
The format draws on structured product feeds that merchants already maintain for platforms like Google Shopping. This lowers the barrier to entry: retailers with existing Google Merchant Center feeds can potentially repurpose that data for ChatGPT advertising with minimal additional setup.
OpenAI's $2.5 Billion Ad Revenue Target
The carousel launch is part of OpenAI's broader push to monetize ChatGPT's massive user base through advertising. The company has publicly stated a target of $2.5 billion in advertising revenue for 2026. To put this in context, that would make ChatGPT's ad business roughly comparable to Pinterest's advertising revenue—a remarkable achievement for a platform that only recently began showing ads.
The timing is deliberate. By launching the carousel format ahead of Q4, OpenAI is positioning ChatGPT as a viable holiday shopping destination. The fourth quarter traditionally accounts for 25–30% of annual retail revenue, and advertisers allocate their largest budgets during this period. A compelling ad format launched in Q3 gives advertisers time to test, optimize, and scale campaigns before the holiday rush.
Industry Reaction
Advertising industry leaders have responded with cautious optimism. Agency executives have noted that the carousel format brings ChatGPT advertising closer to parity with established shopping platforms, making it easier to justify budget allocation. The visual richness of carousels addresses a key limitation of the earlier single-product format, which struggled to capture attention in a conversational interface.
Adthena's CMO noted that product carousels signal OpenAI's intent to compete directly with Google Shopping and Amazon for product discovery budgets. The ability to show multiple products in context—within a conversation where the user has already expressed purchase intent—creates an advertising environment with potentially higher conversion rates than traditional display advertising.
What Shopify Merchants Should Know
For Shopify merchants, the emergence of ChatGPT advertising represents a new channel that deserves attention but not panic. Here's how to think about it:
- Audit your product feeds. If you already maintain Google Shopping feeds through Shopify, you have the foundational data structure for ChatGPT advertising. Ensure your feeds are complete, with high-quality images, accurate pricing, and detailed product attributes.
- Monitor channel performance. As OpenAI opens more advertising inventory, track whether ChatGPT referral traffic appears in your analytics. Early data will help you decide whether to allocate budget.
- Focus on feed quality. Just as with Google Shopping, the quality of your product feed determines ad performance. Invest in structured, complete product data that can be parsed by AI systems.
- Don't over-invest yet. The platform is still early. Test with a portion of your catalog and measure results before committing significant budget.
Bottom line for merchants
ChatGPT advertising is becoming a real channel with real ad formats. The carousel launch signals that OpenAI is building the infrastructure for serious ecommerce advertising. Shopify merchants should ensure their product data is ready, monitor the channel's development, and be prepared to test campaigns when the timing is right for their business. Update, September 2026: OpenAI has since made product feeds mandatory for shopping visibility in ChatGPT, turning the feed audit above from a recommendation into a requirement.
The Bigger Picture
OpenAI's carousel launch is one piece of a larger trend: AI platforms are rapidly building commerce capabilities. Google, Microsoft, Meta, and OpenAI are all investing in shopping features within their AI products. For merchants, this means the future of product discovery is increasingly mediated by AI agents—and the quality of your product data determines whether you show up in these conversations at all.
