ChatGPT users in the U.S. can now make Etsy and Shopify purchases within conversations, marking a next step towards the future of online shopping - both for consumers and the platforms that control product discovery, recommendation, and payments. In other words, OpenAI might be on the path to reshaping who holds power in e-commerce. OpenAI's new "Instant Checkout" feature is available to ChatGPT Pro, Plus, and Free logged-in users buying from U.S.-based Etsy sellers, with more than 1 million Shopify merchants like Glossier, Skims, Spanx, and Vuori "coming soon," per OpenAI.
