“Can Microsoft turn Copilot from a productivity assistant into the agentic checkout surface for the open web?”
Microsoft Copilot is Microsoft's brand for AI assistants spanning Microsoft 365, Windows, and Azure, launched in 2023 on top of the OpenAI partnership. In 2026 the product expanded beyond pure productivity into embedded commerce with Copilot Checkout — letting users buy from Shopify, Etsy, and other retailers without leaving the chat. The strategic question is whether Microsoft can turn the AI assistant into a transactional surface and capture a share of the agentic-commerce funnel, with Stripe as the agentic-commerce payments backbone.
