Amazon DSP and Adform Now Let Marketers Buy ChatGPT Ads Programmatically
On September 10, 2026, OpenAI’s ChatGPT advertising inventory took a significant step toward mainstream media buying. Amazon and Adform announced separate but parallel deals that let advertisers purchase ChatGPT ad placements through existing programmatic infrastructure — without going directly through OpenAI’s own self-serve console. For media buyers who have been sitting out the ChatGPT ads experiment while they waited for familiar buying tools, that wait is now over.
Amazon opened its demand-side platform to select U.S. advertisers as a managed service, with travel brand Delta Vacations named as an early participant. In Europe, Adform — the Copenhagen-headquartered ad-tech platform — announced that OpenAI had selected it as a technology partner for the regional rollout of ChatGPT Ads, with Volkswagen and Vodafone already in testing. Both announcements land on the same day and point in the same direction: ChatGPT inventory is moving into the standard programmatic stack, not staying walled off inside a single self-serve console. If you already have a background in AI search advertising in 2026, these deals are the infrastructure layer that changes who can actually run.
What Amazon DSP announced
Amazon is providing a managed service layer that sits between its DSP and OpenAI’s ad system. Advertisers do not need to build a direct relationship with OpenAI or navigate the standalone ChatGPT Ads Manager — they can extend campaigns from their existing Amazon DSP setup into ChatGPT’s conversational placements.
The mechanics, as described across several coverage sources including Search Engine Land and Digiday:
- Product feed ads. Campaigns use the advertiser’s existing product catalog to automatically generate ad assets — text and image units that appear below ChatGPT responses, labeled as sponsored.
- CPC and CPM buying. Inventory is available on a cost-per-click or cost-per-thousand-impressions basis, matching the standard options already used on other Amazon DSP supply.
- Amazon manages, OpenAI decides. Amazon handles campaign setup and optimization. But OpenAI retains full control over ad delivery and placement within ChatGPT — Amazon does not determine where inside the conversation an advertiser appears.
- Aggregated reporting. Advertisers receive impressions, clicks, cost per result, CPM, and CPC — the standard DSP reporting set, not deeper conversational signals from within the chat itself.
- U.S. only at launch. The pilot is limited to select American advertisers in the managed-service model.
Amazon’s interest in ChatGPT supply is consistent with a pattern that has played out across its DSP over the past 18 months. The company has systematically added premium inventory across Netflix, Roku, Spotify, Disney, Hulu, and ESPN — and its near-zero programmatic-guaranteed fees (compared to the 15–20% competitors charge) make it a competitive buy for high-value supply. Chris Conetta, a senior figure at Amazon DSP, characterized conversational ads as “the fastest growing engagement opportunity for brands.”
Adform’s parallel European rollout
On the same day, Adform announced that OpenAI had selected it as a technology platform partner for the European rollout of ChatGPT Ads — a separate deal, different geography, similar logic. Volkswagen and Vodafone are named as brands already in early testing.
Adform’s selection as a European partner is meaningful for reasons beyond its own client list. Many European brands that have been cautious about direct OpenAI relationships — partly due to data residency concerns and partly due to procurement complexity with a new vendor — can now access ChatGPT inventory through a platform they already have a contract with. The European rollout of ChatGPT Ads across 31 markets began in August 2026; Adform gives European buyers a familiar on-ramp into that inventory.
The pairing of Volkswagen and Vodafone as early participants also signals something about the target advertiser profile: large enterprise brands with complex multi-market media plans who need a managed, accountable buying relationship rather than a self-serve console.
How programmatic buying differs from OpenAI’s self-serve console
OpenAI’s own Ads Manager, which opened to the public in July 2026, lets any business create a campaign directly inside OpenAI’s platform. The Amazon DSP and Adform deals add a different path. Here is how they compare:
| Dimension | OpenAI self-serve console | Amazon DSP / Adform |
|---|---|---|
| Who it’s for | Any advertiser, no minimum | Existing DSP clients; managed service |
| Buying infrastructure | Standalone OpenAI platform | Existing DSP workflow and reporting |
| Data advantage | Contextual signals from ChatGPT | Amazon first-party shopping/browsing data + ChatGPT context |
| Geography | US, UK, Mexico, Brazil, Japan, South Korea | US (Amazon); EU via Adform |
| Setup complexity | Self-serve; build new campaigns | Extend existing DSP campaigns |
| Minimum commitment | Low; set your own budget | Managed service (higher entry point typical) |
The practical difference is workflow and data layering. A performance marketer already running retail media through Amazon DSP can now include ChatGPT placements in the same plan, with the same reporting cadence, rather than setting up a separate vendor relationship and learning a new console. For agencies managing large books of business, that consolidation is more valuable than it might look from the outside.
What the Amazon data layer adds to ChatGPT targeting
ChatGPT’s own targeting is contextual — ads are matched to what a user is actively discussing in the conversation. That is already a richer signal than a short search query. Amazon adds a second layer: its proprietary first-party data on shopping behavior, browsing history, and purchase intent built from hundreds of millions of U.S. consumers.
The combination means an advertiser selling travel gear could theoretically reach a user who is asking ChatGPT about hiking destinations and who has demonstrated recent outdoor purchase behavior on Amazon — rather than relying on the conversational signal alone. This is the same data advantage Amazon brings to its Netflix and Spotify inventory, and it is why the DSP fees that look low on paper still deliver margin for Amazon through data licensing.
What Amazon does not control: which conversations its ads appear in, what the ChatGPT model says around the ad, or the frequency and placement logic inside ChatGPT. OpenAI retains those decisions. Advertisers get the audience intelligence but not full programmatic control over the placement context.
What advertisers should do now
Two groups have different immediate actions depending on their existing infrastructure.
If you already run Amazon DSP: Talk to your Amazon account team this week. The pilot is managed service and limited to select advertisers, which means access is gated by relationship and spend level rather than a public sign-up. Ask specifically whether your vertical and budget profile qualifies for the ChatGPT inventory pilot, and if so, which campaign types (product feed ads vs. other formats) are eligible in your category.
If you are a European advertiser on Adform: Contact your Adform account manager to understand the current rollout timeline. The Volkswagen and Vodafone testing suggests enterprise accounts are being prioritized; the pace of broader availability will depend on how the pilot performs. Even if you are not in the first wave, getting on the interest list now positions you early in the queue.
For everyone else: The self-serve path remains the fastest on-ramp. OpenAI’s own ChatGPT Ads Manager is available without a DSP relationship, at any budget level. If you have not run a test campaign there yet, start with a small capped experiment in your highest-intent product category before programmatic access opens more broadly.
A few things to set up regardless of which path you take:
- Clean your product feed. Amazon DSP’s ChatGPT inventory uses product-feed ads. Incomplete titles, missing images, or stale pricing in your feed will hurt ad quality and match rates before the campaign even launches.
- Set up assisted-conversion tracking. ChatGPT placements are discovery-stage, not last-click. A user who sees a sponsored recommendation inside a ChatGPT conversation will often convert hours or days later via a different channel. Without assisted attribution, the channel will look like it underperforms.
- Read the brand-safety terms carefully. OpenAI controls placement context. Review what category exclusions and safety-label controls are available in the buying interface before committing spend.
What this means for the ChatGPT ads ecosystem
The September 10 announcements are the clearest signal yet that ChatGPT advertising is moving from a single-platform experiment into a distributed inventory model. OpenAI is not trying to build the next walled-garden ad network; it is selling supply to the infrastructure that already exists — Amazon’s DSP, Adform’s platform, Criteo (which already powers 2,000-plus brands on ChatGPT). Each partnership accelerates adoption by removing the friction of a new vendor relationship.
For marketers, the implication is that ChatGPT inventory will become routine media in the same way that connected TV inventory became routine once it started flowing through existing DSPs. The question will shift from “should we try ChatGPT ads” to “how do we optimize for them the same way we optimize for every other programmatic channel” — which means better creative briefing for conversational contexts, cleaner product data, and measuring the right metrics from the start.
Frequently asked questions
What did Amazon announce about ChatGPT ads on September 10, 2026?
Amazon opened its demand-side platform to select U.S. advertisers as a managed service for purchasing ChatGPT ad inventory. Campaigns use product-feed ads (text and image units appearing below ChatGPT responses), available on CPC and CPM. OpenAI controls ad delivery; Amazon handles campaign setup and optimization. Delta Vacations is a named early participant.
What is Adform’s role in ChatGPT ads?
Adform is OpenAI’s selected technology platform partner for the European rollout of ChatGPT Ads. Volkswagen and Vodafone are named as brands in early testing. This gives European advertisers a programmatic path into ChatGPT inventory through an existing ad-tech vendor rather than requiring a direct OpenAI relationship.
How is buying through Amazon DSP different from using OpenAI’s Ads Manager directly?
OpenAI’s self-serve console is open to any advertiser at any budget. Amazon DSP is a managed service for existing DSP clients, adding Amazon’s first-party shopping data as a targeting layer on top of ChatGPT’s conversational context. DSP buyers can extend existing campaigns rather than building new ones from scratch inside a separate platform.
Is ChatGPT programmatic advertising available outside the U.S.?
OpenAI’s self-serve ads cover the U.S., UK, Mexico, Brazil, Japan, and South Korea. The Amazon DSP pilot is U.S.-only at launch. Adform’s European partnership extends programmatic access to European markets, with Volkswagen and Vodafone among the first brands testing. Broader availability timelines have not been announced.
