Shopify Releases Fall '26 Editions "Exponential", Bringing Products and Checkout into…

Shopify's latest release, Fall '26 Editions "Exponential"

The main thread of Fall '26 Editions is very focused: on one hand, it brings products, checkout, and store management into Agents such as ChatGPT, Claude, Gemini, Copilot, Muse, Grok Bot, and Instinct; on the other hand, it takes the merchant backend's Sidekick, Canvas, marketing autopilot, and payment risk control up another notch. Expo Mode, which Tobi specifically called out, is an easter-egg-style interaction on the Editions official website built with Google's new HTML-in-Canvas API. https://t.co/e6MUcOFWw6

Following the order Tobi shared · The new Edition goes live, "this is a very fun building window right now" · Shop Pay can enter personal Agents and can also check out on non-Shopify stores; claims about 400 million Shop Pay users, and opens it to developers · Add shopping to Agents: capabilities like https://t.co/4imrNdCD7i; Shop login, Shopify Catalog, and Shop Pay as a complete set; Catalog begins to include brand products not on Shopify · Sidekick can stage multiple steps of changes at once, and is stronger at writing code too · Canvas: claims about 20% faster from a blank theme to opening a store, with more customizable design. · Product data can be customized by sales channel · POS can recognize more in-store customers (network-effect talking point) · Shop App supports one checkout across multiple brands; web version of Shop is more personalized · Campaign Autopilot opens to all merchants and continues to add channels; SEO suggestions are a new addition · Find Expo Mode: built with Google's HTML-in-Canvas API

What is Expo Mode? In the page source it corresponds to HtmlInCanvasEntry / expoMode: it hints that "there is more on the page," and on desktop it can be opened with Shift + ~ (the copy also calls it Growth Mode); when unsupported, it directs to an address with ?expo-mode. The component strings include jumping, falling into pits, distance, node / word count statistics, and so on; in essence, it turns the Editions page into a playable Canvas easter egg, showing off the new tech stack along the way, and is not a business operation feature in the merchant backend.
