# The checkout relationship ultimately belongs to the retailer, not the AI platform

**Claim:** Despite aggressive retailer–AI partnerships, a strategic consensus is forming that **discovery can happen on the AI platform, but checkout must happen in the retailer's environment.**

[[entity-kartik-hosanagar]] cites [[entity-walmart-d3]]'s adaptation after [[entity-openai-d5]] killed Instant Checkout in March 2026 (see [[claim-autonomous-checkout-difficulty]]): Walmart integrated its **Sparky** agent ([[entity-sparky]]) into ChatGPT but **routed customers back to Walmart's ecosystem** for account linking, loyalty, and payment. He notes, however, that [[entity-google-d3]]'s ongoing push for **in-chat checkout via Google Pay** remains an open threat (see [[question-google-in-chat-checkout]]). The strategic response is the action [[action-retain-checkout-loop]].

**Confidence:** Medium (as stated). **Testable:** Yes.

*Enrichment status — supported as a strong trend, NOT a settled consensus.*
- **Supported:** OpenAI shifted toward **merchant-controlled** checkout; Checkout.com — "the merchant owns the checkout, not the AI platform"; PayPal frames protocols around merchant-of-record status.
- **Mixed / contested:** Google's UCP explicitly aims to own more of the checkout interface ("buy… without leaving Google"), so platform strategies currently **diverge**. Some merchants may *prefer* in-surface checkout for conversion and access to platform fraud rails, trading control for scale. Frame this as "a strong trend among some players" rather than industry-wide consensus.
