Bannerflow adds OpenAI (ChatGPT) Catalog Ad Capabilities
Bannerflow announced that its Social Dynamic Ads platform now supports OpenAI catalog ads, enabling retailers to generate product ads for ChatGPT directly from their existing product feeds. OpenAI began serving ads in 31 European markets on August 24, 2026, with a self-serve beta following on August 31. Bannerflow's new template simplifies the process by asking for key product details and automatically generating a catalog file in OpenAI's required format, with customization options and automatic price/availability updates. The feature is positioned as an early-mover advantage for retailers, though targeting and measurement are currently limited in Europe.
This launch positions Bannerflow as an early enabler for retailers to enter OpenAI's emerging ChatGPT ad ecosystem, leveraging existing product feeds to reduce friction. It signals a strategic move to capture demand in a new, rapidly growing channel.

OpenAI launches product carousels in ChatGPT ads
OpenAI has added a product-carousel ad format to ChatGPT that displays multiple products in a single placement at the bottom of user conversations, built from retailers' product feeds. While carousels currently surface items from a single retailer, the system supports showing multiple retailers side-by-side. OpenAI's ad platform automatically determines whether to serve a single-product ad or a carousel. Separately, an AppsFlyer integration lets roughly 40 brands (including Grubhub) attribute app installs, in-app purchases, and subscriptions to ChatGPT ads, though it does not measure incrementality. The rollout follows automation that enables retailers to bulk-create product-feed campaigns and includes guidance ahead of Q4 holiday spending. Together these moves create basic infrastructure for performance advertising on ChatGPT, even as advertiser control, measurement depth and scale remain open; reported ad-revenue targets include $2.5 billion for 2026 and $100+ billion by 2030.
Adform becomes OpenAI tech platform partner for ChatGPT ads in Europe.
Adform has been named a technology partner for OpenAI's ChatGPT Ads in Europe, allowing advertisers to plan, control, and measure chat-based campaigns within its omnichannel platform, which now includes a unified view of the customer journey by connecting ChatGPT conversions with other campaigns. Volkswagen and Vodafone are early testers, focusing on brand presence and channel performance. The rollout began in August 2026 across 31 European markets, supporting ads on free and lower-cost plans, with paid plans remaining ad-free. Advertisers can use CPM, CPC, conversion optimization, geo-targeting, and custom audiences. OpenAI ensures ads are clearly labeled and do not affect ChatGPT responses. Additionally, Deutsche Bank has launched a ChatGPT advertising campaign for its digital wealth management product, though details are paywalled. These moves align with broader AI trends, including OpenAI's DevDay focus on economics and infrastructure, and Google's Gemini 4 Argon emphasizing reasoning for longer tasks. Furthermore, PixVerse and OpenAI have announced a collaborative educational initiative called 'Prompt to Production' to enhance AI-powered creative workflows, comprising two joint webinars and an ongoing video series, demonstrating efficient transitions from ideas to production-ready content using AI tools.
OpenAI Tests Multi‑Advertiser Ads in ChatGPT
OpenAI has begun testing a new ad format in ChatGPT that can show multiple relevant advertisers within a single sponsored placement, expanding available inventory without increasing ad frequency. The test is currently limited to a small subset of ChatGPT ads and OpenAI says eligible impressions will be sold via a second‑price auction. At the same time, OpenAI updated its Ads Manager with familiar campaign features: conversion of lifetime to daily budgets, one‑click cloning of CPM to CPC campaigns, custom CPM maximum bids for impression campaigns, bulk editing tools, and a shift to average daily budget pacing. The platform also expanded geographic targeting beyond English‑speaking markets to include the UK, Japan, South Korea, Brazil and Mexico. OpenAI frames the changes as improving product discovery for users while giving advertisers more ways to reach high‑intent audiences during conversational research.
