The startling fact from the past week
Updated on June 5, 2026

ChatGPT ran its first ad in February. It's already a $100-million ad business — and now it's self-serve.

On May 5, OpenAI opened a self-serve Ads Manager and turned on product-feed automation — connect the same catalog you already send Google Shopping, and ChatGPT builds the ads for you. Criteo, its first ad-tech partner, says a thousand-plus brands are already live, and that AI-referred shoppers convert at close to twice the rate of traditional search in some categories. The answer box is becoming an ad unit. The search playbook just grew a third front — and the money is coming out of "new discovery" budgets, not your existing search line.

The Marquee

OpenAI just made the answer box self-serve — and the land grab has started.

What happened. OpenAI launched self-serve ChatGPT ads plus product-feed automation. A retailer connects a catalog — the same structured file it already sends Google Shopping, up to a million SKUs — sets a few filters, and the platform generates the ads itself, placed below the answer and labeled sponsored. eMarketer pegs ChatGPT's young ad business at roughly $100 million annualized.

Why it matters. Criteo reports more than a thousand brands already live, with consumer-electronics, lifestyle, and home categories converting close to twice traditional search and click-through about three times comparable formats. The edge is the signal: ChatGPT serves on conversational intent — "what's a good gift for my dad who fishes?" — not a keyword or a browsing trail, so it catches the decision earlier. eMarketer projects U.S. AI-driven search ad spending to climb from about $1.1 billion in 2025 to $26 billion by 2029, a 23-fold jump. Call it the 2003 AdWords land grab on fast-forward: the early flag-planters bought cheap clicks and a category authority that compounded for years. The barrier this time is almost nothing — if your feed runs on Google Shopping, you're most of the way in.

If your product feed already runs on Google Shopping, you can be live in ChatGPT this quarter — claim the conversational-intent slot before your category fills in.
Three Quick Hits

Three other things that moved this week.

97% of marketers use AI. 70% of shoppers say the ads have no soul.

Canva's third State of Marketing and AI report found 97% of marketing leaders now use AI in daily creative work — but 70% of consumers say AI-made ads are "missing their soul," and 78% would rather see ads made by people.

What to do: add one human-reviewed checkpoint to your top creative workflow this month, and disclose AI use — 74% of consumers trust a brand more when a policy governs it.

Google turned Search, Gemini, YouTube, and Gmail into one cart.

At Marketing Live, Google unveiled Universal Cart — one cart that follows a shopper across Search, the Gemini app, YouTube, and Gmail, with launch partners Nike, Sephora, Target, Walmart, and Wayfair. It rolls out in the U.S. this summer.

What to do: add Google's new "conversational attributes" to your Merchant Center feed before summer — products without them won't surface in AI shopping.

AI is thinning the martech stack — and the marketing org.

The martech landscape grew just 0.7% this year — about 1,500 tools added, 1,300 gone — as AI folds point tools into platforms. Underneath, 47% of B2B companies say they've cut marketing roles because of AI.

What to do: name two tools in your stack an AI feature could absorb by year-end, and consolidate on purpose before the budget does it for you.
Brand Spotlight

Attentive turned its texting platform into an agent that runs the campaign.

Attentive — the SMS and email platform that drove more than $6 billion in brand revenue in Q1 alone — used its Thread 2026 event on May 26 to unveil agentic features shipping before Black Friday, led by AI Campaigns — which orchestrates an end-to-end campaign from customer signals — plus a conversational Reporting Agent and Brand Voice 2.0 to keep AI-written messages on-brand. Lands' End, Carter's, and Crate & Barrel renewed or expanded as they consolidate around AI-led personalization. The move tells you where this is heading: the vendors you already pay are quietly becoming the agents.

Before you buy a new AI tool, check what the platforms you already pay for shipped this quarter — the agent may already be in your stack.
The Marketer's Playbook

Three things to consider this week.

Three concrete moves a marketer could make. If you do nothing else from this issue, consider these.

01

Find out whether your product feed can go live in ChatGPT.

Pull the catalog you send Google Shopping and ask your media team if it can run in ChatGPT through a partner like Criteo. Early movers are buying cheap clicks and category authority. By Friday.

02

Add one human checkpoint — and an AI-disclosure line — to your top creative workflow.

The soul gap is real, and 74% of consumers say they trust a brand more when a written policy governs its AI use. Make the review a step, not an afterthought. By next issue.

03

Map two stack tools an AI feature could absorb by year-end.

The martech count is flat because platforms are eating point tools. Decide which two you'd consolidate, deliberately, before the next budget cycle decides for you. Before Q3.

A note from Ged

This is not an assignment. It's for your use as you see fit — read it, skip it, forward it, file it. The Playbook is a set of options, not a checklist.

Michigan sentiment sits at a record-low 44.8, year-ahead inflation expectations climbed to 4.8%, and Strait-of-Hormuz gas pressure is leaking into prices — the shopper your AI is selling to is the most pessimistic since the survey began in 1952.
