OpenAI has launched "Instant Checkout," allowing ChatGPT users to purchase products directly within the chat interface, significantly competing with Google Shopping and Amazon. Currently available to all U.S. users, the feature integrates with Etsy and will expand to over one million Shopify merchants. Powered by the Agentic Commerce Protocol alongside Stripe, this innovation aims to streamline shopping while driving up Etsy's stock by 16%. OpenAI asserts it enhances the buying experience significantly.
