Overview

AI agents that autonomously discover, compare, negotiate, and purchase products on behalf of consumers and businesses. McKinsey projects this channel will drive $3-5T globally by 2030. Three competing payment protocols emerged in 2026: Stripe's Machine Payments Protocol (with OpenAI for ChatGPT), Google's Universal Commerce Protocol (coalition-backed), and Visa's Trusted Agent Protocol. Forrester predicts 20% of B2B sellers will face agent-led quote negotiations by end of 2026. 45% of shoppers already use AI shopping assistants. The SaaS opportunity spans agent-native checkout, identity/payment layers, and merchant tools for AI agent optimization.
