State of Play

Revised Nov 1, 2026

The moment. Search is paying for the AI that is replacing it. Adweek’s Kendra Barnett reports Alphabet’s Q3 search revenue growth slowed to 12% from 17% the quarter before, with executives citing AI Mode’s lower ad monetization, and TechCrunch has Google taking AI Mode ads international anyway. Google is also moving to personalize those ads with signals from Gmail and Photos. Meta rebuilt the engine underneath its feed: AdExchanger’s Allison Schiff reports an LLM-based ranking model and a retrieval overhaul letting Andromeda score more than a billion ads per second. OpenAI kept building its ad business in public, taking ChatGPT ads to 26 more countries for 89 in all, adding an automatic bid strategy, and applying creative enhancements to existing ads from October 30 unless an advertiser opts out. The FTC cleared Publicis’s LiveRamp acquisition under a consent order with a five-year data firewall.

The tension. The platforms are editing the work and moving the liability to the buyer. Adweek has Meta’s AI reworking creative without being asked, and Meta’s new terms make advertisers solely responsible for whatever it generates, a change Meta pushed from October 30 to November 20 after publisher trade bodies objected. Identity is closing in one browser and opening in another inbox: Apple confirmed it has broken identity resolution vendors’ tracking on Safari, while Google’s policy now lets Gmail, Drive and Photos data feed ads once a user connects them. CTV’s plumbing is still the weak joint: The Measure’s Jon Lafayette reports Wurl finding 89% of CTV ad requests lack a usable program name, and executives from Magnite to The Trade Desk name frequency waste as the problem nobody has fixed. Indie agencies now ask aloud whether they need a DSP at all.

Who’s moving. Google, with search growth at 12% and AI Mode ads going global. Google again, on Gmail and Photos signals in AI Mode ads. Meta, scoring every impression with an LLM. Meta again, delaying its terms to November 20. OpenAI, at 89 countries. The FTC and Publicis, on a five-year firewall around LiveRamp. Apple, closing the Safari workarounds. Wurl, on CTV requests with no program name. Skydance, weighing Google over FreeWheel. FreeWheel, following NBCU in the Comcast split. Madhive, adding AdImpact spend data across 210 markets. Pinterest, launching Programmatic Deals with Magnite.

What the desk is watching. Whether Meta’s November 20 date holds, and whether AI Mode’s ad load closes the gap in Google’s search growth or widens it.
