👋 If you've been trying to figure out where AI shopping is actually heading, Gap's CTO just handed you the clearest answer anyone has given all year.
This week he announced a deal with Google. And in one sentence he explained something that most brands, most agencies, and most tech journalists completely missed.
There are two competing systems for how AI sells products. They work differently. They give brands different levels of control. And right now, most brands don't know which one they're on, or whether they're on either.
That's what this issue is about.
THE SIGNAL
When someone asks ChatGPT "what's the best moisturiser for dry skin," two things have to happen.
The AI has to find your product. And then someone has to actually buy it.
Turns out, two different companies built two different systems for how that works. And they disagree on something pretty fundamental: who's in charge.
Gap's CTO picked a side this week. Most people missed what he actually said.
Per The Information, the integration wasn't working. Turns out users kept doing what they've always done: asking ChatGPT what to buy, then leaving to actually buy it somewhere else.
OpenAI's statement was telling: "We're prioritizing making ChatGPT search and product discovery great."
Discovery. Not checkout. Not transaction. Discovery.
Here's why that matters for you: the brands that have been quietly investing in AI recommendation visibility? They just got validated. By the company that spent six months and a Stripe partnership trying to build AI checkout... and then stopped.
The race isn't to own the transaction. It's to own the recommendation.
Everything else follows.
THE BREAKDOW
Two systems. One big difference. Here's what it means for your brand.
Two systems. One big difference. Here's what it means for your brand.
September 2025: OpenAI and Stripe build a system called ACP. The idea is simple. When someone asks ChatGPT what to buy, ChatGPT reads your product catalog, picks the best match, and handles the whole transaction inside the chat. The AI does the selling. You just ship the order.
January 2026: Google and Shopify build a competing system called UCP. Backed by Walmart, Target, Etsy, Wayfair, Visa, Mastercard, and 20+ others. Different idea entirely. When someone asks any AI assistant what to buy, your product shows up. But the purchase happens on your own website, in your checkout, on your terms. You stay in control of the whole experience.
Both are free to use. Both put you in front of AI shoppers. They just do it differently.
Here's the simplest way to understand the gap.
ACP is like getting your product stocked at the world's most popular store. Massive reach. But it's their store. Their rules. Their relationship with the customer.
UCP is like having your own store that every major AI platform can send customers to. You own the relationship. You own the data. You own the checkout.
Gap's CTO said it straight: "Google's system was designed for merchants to have better control. OpenAI's system was designed more for discovery."
One gets you found. One keeps you in control. Most brands need both eventually. But right now most don't have either.
One thing nobody's talking about: Amazon looked at both systems and said no thanks. Blocked the whole thing. Built its own AI shopping assistant instead and walled off 600 million products from ChatGPT's results. Amazon is betting it doesn't need to play with anyone else. Every other retailer is betting the future of AI shopping is open.
Somebody's going to be wrong. We'll find out in a couple of years.
What we know today: people who discover products through AI are buying at 5 to 10 times the rate of normal online shoppers. The channel is real. The brands showing up are winning quietly.
RANDOM THOUGHT:What if the whole debate about which system wins doesn't matter at all, and the only thing that separates the brands getting recommended from the ones being ignored is whether their product descriptions are written for humans instead of spreadsheets?
THE MOVE
One thing. Five minutes.
Find out which system your store already uses.
On Shopify? Good news. You're already connected to Google's system by default. Your products are in the mix. The question is whether what AI reads about your products is actually good enough to get you recommended. Being in the system and being chosen by the system are not the same thing.
Not on Shopify? Go to your platform's help centre and search "AI commerce" or "agentic." See what they've built. If the answer is nothing, you need to know that today, not when your competitors have already figured it out.
You don't need to understand the tech. You just need to know which side you're standing on.Prompt Me:
Does your team know whether your store is set up for AI shopping right now?
Hit reply. Yes, no, or "I had no idea this was even a thing."
I'll share the results next week.
