PayPal will soon be integrated into Google’s AI-powered checkout, offering consumers a familiar payment option as automated shopping tools evolve. The move supports Google’s Universal Commerce Protocol (UCP), an open standard designed to enable AI-driven shopping and payments across platforms.
The partnership, confirmed in a recent press release and by PayPal CEO Alex Chriss, builds on the collaboration announced last year and marks a shift from planning to execution as AI agents take on a larger role in online commerce.
Google introduced UCP at the National Retail Federation conference, describing it as a shared technical language that allows AI systems, merchants, and payment providers to interact seamlessly. The goal is to reduce friction as AI expands beyond product recommendations into checkout, payments, and customer support.
According to Google, UCP is platform-agnostic and replaces fragmented, custom integrations with a single standard. It builds on earlier initiatives like the Agent Payments Protocol and works alongside frameworks such as Agent2Agent and the Model Context Protocol to advance agentic commerce.
Google plans to expand the Universal Commerce Protocol beyond checkout to include smarter product recommendations, loyalty programs, and more personalized shopping experiences across its platforms.
PayPal is one of several major companies backing UCP, alongside retailers and e-commerce platforms such as Shopify, Etsy, Wayfair, Target, and Walmart. Shopify said its large-scale checkout experience helped ensure the protocol can support global adoption.
PayPal views interoperability as UCP’s main benefit, arguing that open standards allow merchants to adopt AI-driven commerce while maintaining trust, transparency, and control over payments. Its familiar payment layer could also help consumers feel more secure using AI-powered shopping.
However, some analysts caution that AI-based checkout could weaken merchants’ direct relationships with customers. Richard
Crone of Crone Consulting warned that if purchases move entirely into AI assistants like Gemini, merchants may lose their final point of contact with shoppers.
The announcement comes as PayPal continues to expand, investing in European payments firm Klearly and increasing its physical presence in New York with a major office lease near Google.
