Shopify sends compare-at prices to AI shopping agents
Shopify Catalog now shares compare-at prices with AI shopping agents, so your markdowns show up as strikethrough deals. Check your reference prices first.
Shopify now sends your compare-at price to AI shopping agents through Shopify Catalog. Until this week, an agent reading your catalog saw only the current price, so a sale on your storefront was invisible to a buyer who asked an AI. Now the agent can see the markdown and may show it as a strikethrough deal. That's good news if your compare-at prices are honest. If they aren't, an agent now repeats the number for you.
What actually happened
The Shopify changelog entry, dated October 9, says Shopify Catalog now shares compare-at prices with AI shopping agents so they can "see when a product is marked down." The entry doesn't name specific agents.
The catalog mapping help page fills in the details:
- A toggle controls it. It's in the Compare-at section of your catalog mapping settings in admin. Off means agents get only the current price.
- Only real markdowns go out. Catalog sends the compare-at price only when it's higher than the current price.
- It travels as UCP data. The value goes out in the
list_pricefield of the Universal Commerce Protocol variant spec, the same protocol behind agent checkout in Google's Gemini. - Your store already has a default. Shopify says it picks the default from your product data, and changes to how you use compare-at prices don't update that choice automatically. Go look at what it picked.
Why compare-at prices matter more now
On your own storefront, a compare-at price is design. In an AI agent's answer, it becomes a claim: "was $89, now $59." The agent can't tell whether $89 was a real price or a number someone typed in years ago and never changed.
The FTC's Guides Against Deceptive Pricing say a former-price comparison has to be based on "the actual, bona fide price" you charged regularly. That rule applies whether a customer reads it on your product page or in an agent's answer.
What we'd do this week:
- Export products with compare-at prices. Sort by date last changed. Old reference prices are the risk.
- Remove any compare-at price you never actually charged. If you can't back it up with order history, delete it.
- Check the toggle. Turn it on when the data is clean. Leave it off until then.
- Track agent traffic as its own channel. If markdowns now reach agents, measure whether they bring in orders.
Key takeaways
- Shopify Catalog now shares compare-at prices with AI shopping agents, per an October 9 changelog entry
- Only compare-at prices above the current price go out, in UCP's list_price field
- A toggle in catalog mapping settings controls it, and your store already has a default selection
- Agents may show these as strikethrough deals, so a stale reference price becomes a public claim
- FTC pricing guides require former prices to be ones you actually charged regularly
Agents now quote your catalog, so the catalog has to be right. We audit Shopify product data, including prices, compare-at history, stock, and UCP mapping, before an AI repeats it to your buyers. See our commerce builds, or ask us to check your catalog.
