I was going to write about the new episode of Paramount, Netflix, and WB’s “Battle for the Last Subscriber,” but there will be time for that as the saga unfolds.
Today, it’s more important to pay attention to Instacart, the first retailer to offer a full grocery checkout experience inside ChatGPT using OpenAI’s Agentic Commerce Protocol (ACP). Users can now browse items, fill a cart, and pay without leaving the conversation.
The integration connects ChatGPT’s models with Instacart’s real-time grocery network. Mention a recipe or ingredient, and ChatGPT can surface the Instacart app, identify the correct items, assemble a ready-to-review cart, and take payment inside the chat. Instacart then routes the order to its shopper network for fulfillment. The entire journey from inspiration to delivery happens in one place.
We have to watch this closely. OpenAI is positioning ChatGPT as a platform where apps become service endpoints. The user mentions a need. The agent identifies an app. The app handles the transaction. Retailers such as Walmart, Target, and PayPal are already working with OpenAI across different integration layers. Instacart’s Instant Checkout is the clearest example to date of how “share of prompt” results in a transaction.
This raises some practical questions. If checkout moves into the chat interface, the point of sale shifts with it. Discovery, recommendation, and execution begin to collapse into a single interaction. Price competition becomes more transparent. Brand differentiation becomes harder. The retailer’s relationship with the customer becomes mediated by an AI that controls the conversation flow. Most importantly, critical data is captured by OpenAI.
This UX offers a new level of convenience. If it catches on, we are going to be faced with new marketing challenges as the friction between chatting and purchasing is agentically reduced.
