PayPal in ChatGPT Ended New
PayPal's ACP deal for ChatGPT checkout
PayPal adopted ACP in 2025 to power ChatGPT Instant Checkout, which OpenAI ended in March 2026.
Why it matters
The in-chat checkout this deal was built for has ended. PayPal merchants are now reached in ChatGPT through product discovery, with payment taken on their own checkout.
What the source says
PayPal adopted the Agentic Commerce Protocol so ChatGPT users could pay with PayPal and PayPal merchants could sell through Instant Checkout. OpenAI ended standalone Instant Checkout on 24 March 2026 before this launched; purchases from ChatGPT now complete on merchants' own sites or in ChatGPT apps, where PayPal can still be offered.
