Criteo becomes first ad tech partner in OpenAI’s ChatGPT ad pilot

Criteo immediately introduced it’s the first promoting expertise firm to combine with OpenAI’s promoting pilot inside ChatGPT, marking a notable enlargement of the AI platform’s nascent business infrastructure simply weeks after OpenAI began formally testing ads in ChatGPT on February 9. The partnership covers ChatGPT’s free and Go subscription tiers in america and was disclosed on March 2, 2026.

The announcement locations Criteo (NASDAQ: CRTO) on the heart of a fast-moving experiment in conversational promoting – one the broader trade has been watching since OpenAI confirmed advertising plans on January 16 after months of delays and inner reorganization.

What the mixing entails

In response to the press launch, Criteo’s digital promoting platform will start connecting manufacturers to ChatGPT’s promoting surfaces “within the coming weeks” as a part of the continued pilot. The combination is restricted to america. It covers the ChatGPT Free tier and the Go tier, priced at $8 per 30 days – the identical two tiers the place OpenAI is at present working its broader promoting take a look at.

Criteo prompts greater than $4 billion in annual media spend, based on the corporate, and works with 17,000 advertisers globally. The platform connects manufacturers, retailers, and publishers by means of what it describes as commerce intelligence and AI-driven decisioning expertise. That scale positions Criteo as a significant conduit between OpenAI’s rising consumer base and the advertisers searching for entry to it.

The corporate’s CEO Michael Komasinski framed the mixing when it comes to discovery somewhat than direct response. “Via this pilot, we’re serving to form how promoting can assist discovery and consideration inside Massive Language Mannequin (LLM) platforms, grounded in experiences which are additive, related, and constructed on consumer belief,” Komasinski stated, based on the announcement. The language intentionally sidesteps the transactional framing that has drawn criticism in agentic commerce discussions – as an alternative positioning the hassle as a technique to form model consciousness inside AI-assisted search.

The conversion charge determine

One concrete determine within the announcement stands out. In response to Criteo, customers referred to retail web sites from LLM platforms like ChatGPT convert at roughly one and a half occasions the speed of different referral channels. This determine is drawn from a pattern of 500 Criteo retailers in america, noticed in February 2026.

The pattern interval – a single month, drawn from a selected subset of the corporate’s retailer base – means the discovering must be learn as preliminary. The methodology has apparent limitations: 500 retailers is a fraction of Criteo’s roughly 17,000 advertiser purchasers, and a single month of information is a slim window. Nonetheless, the path of the metric issues. Excessive conversion charges from AI-referred site visitors would recommend that customers arriving from ChatGPT are additional alongside in buy consideration than typical referral audiences. If the sample holds at scale, it will present a business rationale for the premium pricing OpenAI has already established.

OpenAI set the minimal advertiser dedication for the ChatGPT pilot at $200,000, based on reporting cited by PPC Land in late February. The CPM charge stands at $60 – effectively above typical Meta CPMs, which regularly fall beneath $20, and akin to NFL broadcast stock. For advertisers accustomed to efficiency benchmarks, a 1.5x conversion carry would meaningfully change the return-on-investment calculation at these charges.

OpenAI’s promoting trajectory

The ChatGPT promoting pilot has moved shortly from announcement to stay placements. OpenAI first confirmed plans on January 16, 2026, ending months of inner hypothesis. The corporate had issued a “code pink” directive as not too long ago as December 2, 2025, pausing advertising development to pay attention sources on bettering ChatGPT’s core performance amid aggressive stress from Google’s Gemini.

The reversal was swift. By February 6, OpenAI started accepting advertisers, with early confirmed individuals together with Goal, Ford, Mrs. Meyer’s, and Adobe. Holding corporations WPP Media, Omnicom, and Dentsu signed on as launch companions. The primary independently verified advert sightings arrived within the third week of February, when search intelligence agency Adthena analyzed greater than 500 prompts and found ads appearing in roughly 0.8% of responses. Confirmed advertisers included Expedia, Qualcomm, Greatest Purchase, Enterprise Mobility, and The Knot Worldwide – a mixture of journey, client electronics, and retail.

Placements sit on the backside of ChatGPT solutions, are clearly labeled as sponsored, and don’t seem close to delicate or regulated matters together with well being, psychological well being, and politics. The Plus, Professional, Enterprise, and Enterprise subscription tiers are excluded from promoting totally, based on OpenAI’s printed rules. Customers who point out they’re beneath 18, or the place the platform predicts underage utilization, additionally see no advertisements.

One notable technical episode: AdExchanger reported in February that when requested the place advertisements would seem, ChatGPT itself supplied incorrect solutions. An OpenAI spokesperson confirmed the chatbot’s rationalization was false. The incident illustrated the hole between promoting infrastructure and the mannequin’s personal understanding of that infrastructure – a niche that may require decision as companions like Criteo start activating campaigns.

The place Criteo sits within the broader image

For Criteo, immediately’s announcement is a part of a broader push into what the corporate calls agentic commerce – the premise that AI assistants will play a rising function in how shoppers uncover and buy merchandise. On February 5, the corporate introduced its Agentic Commerce Recommendation Service, which demonstrated as much as 60% enchancment in suggestion relevancy in comparison with approaches relying solely on product descriptions, primarily based on inner January 2026 testing. That service makes use of a Mannequin Context Protocol implementation enabling AI assistants to entry Criteo’s suggestion infrastructure with out requiring retailers to switch their backend programs.

The ChatGPT promoting partnership connects on to this infrastructure technique. Criteo’s platform has entry to knowledge from greater than $1 trillion in annual commerce gross sales, based on the corporate. Plugging that knowledge into conversational AI surfaces – the place customers are actively searching for product info – represents a logical extension of the corporate’s current commerce knowledge place.

Accomplice relationships have accrued quickly. In September 2025, Google designated Criteo as its first onsite retail media partner, enabling advertisers to create and handle campaigns throughout Criteo’s retailer stock instantly by means of Google Search Adverts 360. In October 2025, Criteo announced a multi-year partnership with DoorDash for retail media enlargement throughout supply and market environments. The OpenAI integration provides a 3rd important platform relationship inside roughly six months.

These strikes happen in opposition to a difficult monetary backdrop. Criteo reported Q4 2025 revenue of $541 million, a 2% year-over-year decline, with a $25 million headwind from two giant retail media purchasers that lowered their scope. The anticipated complete affect from these shopper adjustments stands at $75 million throughout the primary ten months of 2026. The corporate can also be within the strategy of transferring its authorized domicile from France to Luxembourg – a cross-border conversion that it discussed publicly in October 2025 as enabling better strategic flexibility for potential U.S. transactions.

What this implies for promoting on LLM platforms

The participation of a longtime advert tech middleman like Criteo shifts the ChatGPT pilot from a direct-to-advertiser experiment into one thing extra carefully resembling the programmatic infrastructure that buildings the remainder of digital promoting. Fairly than requiring particular person manufacturers to barter instantly with OpenAI, Criteo’s involvement creates a path for its 17,000 current advertiser purchasers to entry ChatGPT stock by means of a well-recognized platform relationship. That’s how the programmatic ecosystem was constructed on Google, Meta, and Amazon – by means of middleman layers that lowered the operational price of entry.

Whether or not that infrastructure is welcome on all sides shouldn’t be a settled query. OpenAI’s head of monetization Asad Awaninstructed in February that small companies may ultimately create and handle campaigns by means of easy prompts, with out companies or efficiency entrepreneurs. The company neighborhood responded skeptically. The Criteo integration threads a unique path: it preserves the middleman layer whereas connecting it to a brand new floor. The 2 approaches will not be mutually unique – OpenAI may pursue each concurrently.

Skepticism around agentic commerce more broadly has centered on structural challenges: retailers blocking AI brokers to guard their very own media companies, shoppers resisting on-platform checkout, and the issue of intermediating transactions that retailers desire to personal. Promoting inside ChatGPT sidesteps a few of these friction factors. Fairly than finishing transactions, advertisements within the present pilot drive customers again to retailer and model locations. Criteo’s announcement explicitly frames this as “driving incremental demand again to retailer and model locations” – which is in line with the pilot’s said design and avoids the structural battle that has difficult agentic purchasing proposals.

ChatGPT reached 700 million weekly lively customers by mid-2025 and processes roughly 2.5 billion messages every day, based on figures in earlier PPC Land protection. That consumer quantity – mixed with the high-intent sign that Criteo’s pattern knowledge suggests accompanies at the least a few of it – is the core business asset OpenAI is now opening to advertisers. Whether or not that intent interprets to sturdy promoting income on the CPMs OpenAI is charging is exactly what pilots like this one are designed to check. Criteo’s first-mover place provides it each early knowledge entry and the duty of serving to outline what accountable commerce promoting appears to be like like inside an AI context that has, till very not too long ago, been totally free of economic placements.
