# Will Google's in-chat checkout succeed where OpenAI failed?

**Open question:** [[entity-openai-d5]] abandoned **Instant Checkout** over poor conversion (see [[claim-autonomous-checkout-difficulty]]), yet [[entity-google-d3]] is actively pushing agentic checkouts live via **Google Pay** and UCP. Will Google's infrastructure and user trust let it **own the checkout experience**, challenging the consensus that [[claim-checkout-belongs-to-retailer|checkout belongs to the retailer]]?

**Resolution path:** Monitor the adoption and conversion rates of Google's UCP-driven in-chat checkouts over the next **12–18 months**.

*Enrichment note:* Google's UCP explicitly enables buying "without leaving Google," signaling strong platform appetite for end-to-end in-surface flows. In **low-risk, high-frequency** categories with predefined constraints, and as agent-authorization/fraud controls mature, fully in-surface checkout may advance faster than the article implies — meaning the "checkout belongs to the retailer" consensus is genuinely contested, not settled.
