Key points
- The Information reports Shopify shares fell 7.6% after the company disclosed a profit margin decline it attributed to AI.
- Adweek reports suspected AI-assisted attackers injected fake checkout screens into some third-party apps on the Shopify App Store.
- The malicious code sat in a merchant's third-party extension, not in the Shopify platform itself, according to the engineer who found it.
- Shopify removed affected apps, though some have been reinstated; agency clients largely kept their trust in the platform.
Why it matters for marketers: Merchants and agencies relying on Shopify apps should audit third-party extensions and checkout flows, while AI costs may start shaping platform pricing and investor expectations.
Shopify is dealing with AI from two directions. The Information reported that the company's stock fell 7.6% after it disclosed a drop in profit margin that it linked to AI. The article text was not available, so details on the size of the margin decline or the cause are not covered here.
Separately, Adweek reported that suspected AI-assisted attackers injected fake checkout screens into some apps sold through the Shopify App Store. German software engineer Roman Zipp told the outlet he noticed an unfamiliar domain while buying a keyboard from a Shopify-powered store. The source code showed a redirect to a fake checkout page, which appeared designed to collect shoppers' personal information.
Zipp said the code was not in Shopify's platform but in a third-party extension the merchant used. Adweek reported that Shopify removed affected apps, and that some have since been reinstated. Agencies told the outlet their clients largely kept their trust in Shopify and in how it responded.
For marketers, the lesson is that checkout risk can come from the add-ons around a store, such as recommendation tools and post-checkout upsell screens. Teams that run Shopify stores should review which apps are installed, remove ones they no longer use, and test the checkout path from a shopper's view, including checking the URL.
Watch for how Shopify tightens app review and what it says about the reinstated apps. On the financial side, watch whether the company gives more detail on how AI costs affect margins, since that could shape future pricing and product decisions for merchants.
