# Walmart

A major retailer highlighted as an aggressive **early adopter** of agentic commerce protocols. Walmart partnered with [[entity-openai-d5]] for the **Agentic Commerce Protocol (ACP)** and with [[entity-google-d3]] for the **Universal Commerce Protocol (UCP)** (see [[concept-commerce-protocols]]).

Its strategy is described as a **hedge**: Walmart builds its own agent, **Sparky** ([[entity-sparky]]), while simultaneously making its catalog accessible to third-party AI agents. Crucially, while discovery happens on platforms like ChatGPT, the actual **checkout, account linking, and loyalty loop are routed back to Walmart's own environment** — the pattern behind [[claim-checkout-belongs-to-retailer]] and the recommended play [[action-retain-checkout-loop]]. Contrast with [[entity-amazon-d5]]'s walled-garden bet.

*Enrichment note (canonical: walmart.com):* Walmart is cited in protocol discussions as an early UCP participant collaborating with Google and others on agentic-shopping pilots. Public documentation of Sparky specifically is sparse.
