CMO TLDR: ChatGPT Ad Pitch, Amazon’s New Netflix Play
The AI Ad Economy
Criteo Becomes the First Ad Tech Partner to Sell Ads Inside ChatGPT
OpenAI has tapped Criteo as its inaugural ad tech partner to bring advertising into ChatGPT’s free and Go tiers in the U.S. The integration matters because Criteo’s data shows that users arriving from LLM platforms convert at roughly 1.5x the rate of other referral channels, validating conversational AI as a genuine performance surface. With $4 billion in annual media spend flowing through its platform and 17,000 global advertisers, Criteo gives OpenAI instant scale; advertisers can go live in days using existing Criteo Performance Media setups at a confirmed $60 CPM.
Inside the Pitch Deck: How ChatGPT Ads Are Actually Being Sold
Criteo, not OpenAI, is doing the selling, and a pitch deck shared with Digiday reveals the playbook. The core argument: AI shopping compresses the entire purchase funnel into a single conversation, collapsing the distance between discovery and checkout. The pilot allows up to 50 products per campaign, and Criteo’s longer-term ambition is to manage ChatGPT ads alongside display, streaming TV, and social inside one unified platform.

Amazon Audiences Are Coming to Netflix
Starting next quarter, U.S. media buyers running Netflix campaigns through the Amazon DSP will be able to layer on Amazon Audiences for targeting. Amazon claims its identity graph covers 90% of U.S. households, and pairing that with Netflix’s logged-in subscriber base gives buyers something they’ve been demanding: proof that streaming impressions drive actual purchases. With upfronts approaching, Amazon’s 2026 pitch will center on tying content to conversions, backed by trillions of shopping and browsing data points.
HBO Max and Paramount+ Will Merge Into a Single Streaming Platform
Paramount and Warner Bros. Discovery confirmed plans to combine Paramount+ and HBO Max into one service, creating a combined base of over 200 million direct-to-consumer subscribers. CEO David Ellison said the merged platform will compete with the most scaled players in DTC, while stressing that HBO will continue to operate with creative independence under Casey Bloys. The deal follows Netflix’s decision to bow out after Paramount raised its all-in offer to $31 per share.

Meta Replaces Click Through Attribution With a New Social Engagement Metric
Meta will segment social interactions, including likes, shares, saves, and comments, into a new category called “engage through attribution,” effectively dethroning click through as the default reporting metric. The rationale: social media has overtaken search as the world’s top ad spend channel, yet the industry has been measuring it with Google’s ruler. The updated click-through definition will now align more closely with Google Analytics, counting only final link clicks, while all other social signals get their own bucket.

The Trade Desk unveiled OpenTTD, a single login and analytics hub for the several hundred companies that operate across multiple TTD partnership roles (buyer, ad seller, data seller).

Nancy Hall steps up from chief client officer, taking the helm of WPP Media U.S. just one week after CEO Cindy Rose announced WPP is ditching the holding company model and consolidating into four divisions as part of a $676 million annual cost-cutting drive. Hall inherits early momentum from recent wins, including the $210 million SC Johnson and $102 million Norwegian Cruise Line media accounts.
Yahoo has quietly withdrawn from several IAB boards globally, including the U.S. and U.K., as its private equity owner, Apollo Global Management, reportedly reconsiders ad tech investments ahead of its five-year hold maturing. Sources describe a broader pullback from international markets, with APAC operations significantly downsized and efforts to divest Yahoo’s DSP underway since late 2024.
A new pricing model is emerging in AI content licensing that would compensate publishers based on how much value their content contributes to a specific AI query, rather than flat fees or per-crawl rates. Microsoft’s publisher content marketplace is piloting the approach, but the structure remains what its own VP calls “extremely complex.” If it works, it could give publishers recurring revenue tied to how their journalism is used and monetized inside AI systems.
