Is Agentic Shopping a 'Collective Hallucination'? What the IAB Debate Gets Right and Wrong

At the IAB Connected Commerce Summit on April 15, analyst Andrew Lipsman dropped a line that lit up the industry: "It is a collective hallucination that people will shop this way." He was talking about agentic shopping, the idea that AI agents will handle product discovery, comparison, and purchasing on behalf of consumers. He's not entirely wrong. But he's not entirely right either.

TL;DR: The IAB debate exposed a real tension: skeptics are correct that consumers won't complete purchases inside ChatGPT, but they're ignoring the evidence that AI has already reshaped product discovery. Walmart captures 20% of ChatGPT referral traffic. Shopify AI-attributed orders grew 11x. The actual shift? Discovery happens in chat. Purchases happen on the retailer's site.

What Did the IAB Panel Actually Debate?

The IAB Connected Commerce panel brought together analysts, brand leaders, and ad-tech executives to argue over a simple question: will AI agents reshape how people buy things, or is the entire premise overhyped?

The skeptic camp was vocal. Lipsman pointed to the long history of failed buy buttons: "If this were such a benefit to the consumer, then why has no one ever adopted a buy button in any meaningful way?" Sarah Marzano from Emarketer reinforced the point: "Retailers own credibility. They own curation. They own consumer trust."

On the other side, Ryan Verklin from Bayer argued that commerce will happen inside retailer-native AI tools like Amazon's Rufus and Walmart's AI shopping assistant. Scott Collins from Moloco offered the sharpest rebuttal: "It doesn't take a lot of agentic commerce to start changing the economics of retail media."

The audience largely agreed that retail media wouldn't disappear but would be "fundamentally transformed." Which is the right instinct, even if it's a hedge.

The Skeptics Have a Point (Here's What They Get Right)

Lipsman's "collective hallucination" framing is provocative, but it rests on a legitimate observation. Buy buttons have failed everywhere. Facebook tried. Instagram tried. Pinterest tried. None achieved meaningful adoption.

And then there's the most recent example: OpenAI killed Instant Checkout in March 2026, just six months after launching it. The feature let users complete purchases inside ChatGPT without ever visiting the retailer's site. Brands hated it. They were reduced to anonymous fulfillment centers, losing customer data, login information, and loyalty program engagement. Only about 30 merchants were ever live. OpenAI pulled the plug.

If that's not evidence that in-chat purchasing doesn't work, what is?

Marzano's point about retailer trust also holds up. When someone is spending $200 on a kitchen appliance, they want to see the return policy, read reviews on the retailer's site, and check if their credit card offer applies. That trust lives on the retailer's domain, not in a chatbot.

Key Stat: OpenAI discontinued Instant Checkout in March 2026 after brands rejected being reduced to anonymous fulfillment centers. Only ~30 merchants were ever live on the feature.

Where the Skeptics Get It Wrong

Here's the problem with the "collective hallucination" argument: it treats agentic shopping as all-or-nothing. Either consumers complete the entire purchase journey inside ChatGPT, or the whole thing is hype. That's a false binary.

The data tells a different story.

Shopify auto-enrolled 5.6 million stores to ChatGPT via Agentic Storefronts on March 24, 2026. AI traffic to Shopify merchants grew 7x between January 2025 and early 2026, with AI-attributed orders up 11x. Those aren't projections. That's transaction data.

Walmart captures 20% of its referral traffic from ChatGPT, up 15% from the prior month. Target sits at nearly 15%. Etsy is over 20%. These are Similarweb measurements of actual user behavior, not survey responses.

Marzano herself cited Similarweb data on the panel showing that AI-referred visitors spend more time on retailer sites, browse more pages, and convert at higher rates. According to Adobe Analytics, shoppers arriving via generative AI are 38% more likely to complete a purchase than those from traditional search.

And just one day before the panel, David's Bridal launched on ChatGPT via Shopify Agentic Storefronts. Their CTO Scott Saeger: "We want to be the Amazon effect for bridal." A wedding dress is not an impulse buy. If agentic discovery works for high-consideration bridal shopping, the "people won't shop this way" argument starts to crack.

Key Stat: AI-referred visitors convert 38% better than traditional search traffic and browse 10% more pages per visit (Adobe Analytics).

The Real Shift: Discovery Happens in Chat, Purchases Happen on Site

Both sides of the IAB debate were arguing about the wrong question. The framing was "will consumers shop inside AI?" when the real question is "has AI already reshaped how consumers discover products?"

That question is answered. Yes.

The model that works: ChatGPT recommends products based on structured data quality. Users click through to the merchant's website. The retailer keeps the full customer relationship, including login, loyalty, and purchase data. No transaction happens inside the AI.

A Peec AI study of 43,000+ ChatGPT carousel listings found that 83% match Google Shopping's organic results. Optimizing your product feed for Google Shopping directly improves your ChatGPT visibility. One feed, two discovery channels.

Collins from Moloco nailed it: "It doesn't take a lot of agentic commerce to start changing the economics of retail media." Even small shifts in how consumers discover products cascade through the entire retail media ecosystem. And these shifts are not small.

What This Means for Merchants Right Now

You don't need to take a side in the IAB debate to act on what's already happening. The practical takeaway: AI is part of the shopping journey today, and your visibility in AI recommendations is measurable.

Here's what matters:

• Product data quality determines AI visibility. Most product pages have 5-8 structured attributes. AI agents need 30+. When ChatGPT can't determine if your jacket is waterproof or your supplement is vegan, it recommends the competitor whose data answers those questions.
• Your Google Shopping feed is your ChatGPT feed. The 83% overlap between ChatGPT and Google Shopping results means catalog optimization does double duty.
• You're probably already connected. If you're on Shopify, your store was auto-enrolled to ChatGPT on March 24. But connected doesn't mean visible. 80% of brands that fixed their top 3 product data issues saw measurable improvements within 10 days.

The brands showing up in AI recommendations right now are capturing traffic that converts significantly better than traditional search. The ones that aren't are ceding that traffic to competitors. That gap widens by about 10% every 90 days when left unaddressed.

Frequently Asked Questions

What is agentic shopping?

Agentic shopping is the practice of AI agents discovering, evaluating, and recommending products on behalf of consumers. These agents handle research and comparison, then direct shoppers to merchant websites to complete purchases. No transaction happens inside the AI itself.

Is agentic commerce overhyped?

The "checkout-in-chat" vision is overhyped. OpenAI killed Instant Checkout in March 2026 after brands rejected it. But AI-driven product discovery is real and measurable. Shopify AI-attributed orders grew 11x, and Walmart gets 20% of referral traffic from ChatGPT.

Will consumers actually shop with AI?

They already are. 16% of Americans have made a purchase influenced by a ChatGPT recommendation (Morgan Stanley). AI-referred visitors convert 38% better than traditional search traffic (Adobe Analytics).

How should brands prepare for AI shopping?

Start with your product data. Enrich your catalog with 30+ structured attributes per product. Optimize your Google Shopping feed, since 83% of ChatGPT product results match Google Shopping. Then monitor how you appear across AI shopping engines to track your competitive position.

What did the IAB panel conclude about agentic commerce?

The panel largely agreed that retail media wouldn't disappear but would be "fundamentally transformed" by AI. The debate was over degree, not direction. As Scott Collins from Moloco put it: "It doesn't take a lot of agentic commerce to start changing the economics of retail media."

The Bottom Line

Andrew Lipsman is right that full in-chat purchasing is a dead end. OpenAI proved it. But calling the broader shift a "collective hallucination" ignores the data presented on his own panel. AI-referred traffic converts better. Shopify orders from AI are up 11x. Walmart is capturing real referral traffic at real scale.

The question for merchants isn't whether agentic shopping will replace traditional e-commerce. It won't. The question is whether your products show up when AI recommends. Because that traffic is already flowing, and it's converting. Whether you capture it or your competitor does comes down to your product data.

That's not a hallucination. That's a strategy decision.
