AI shopping is creating a strategic divide over how customers reach retailers and complete purchases. Walmart announced an OpenAI partnership on October 14, 2025, intended to enable shopping through ChatGPT, while Amazon has opposed the inclusion of its store in Perplexity’s Comet experience. These positions illustrate different approaches to third-party shopping assistants, rather than a newly confirmed October 2026 rollout.

Key Takeaways

  • Walmart’s announced partnership would let customers shop through ChatGPT using Instant Checkout.
  • Amazon says third-party shopping agents should respect retailers’ decisions about participation.
  • An announced checkout integration is not evidence that the service has launched.

AI shopping moves beyond product discovery

Walmart’s October 2025 OpenAI partnership announcement described a service that would allow customers and Sam’s Club members to move from conversational product searches to purchases within ChatGPT. Walmart said it would handle fulfillment.

The planned experience covers everyday tasks such as meal planning, replenishing household essentials and discovering products. The commercial distinction is checkout: an assistant that helps complete an order plays a different role from one that merely recommends an item.

Walmart Chief Executive Doug McMillon described the partnership as a step beyond the traditional search bar and list of products toward more personalized, contextual shopping. The announcement used forward-looking language and did not specify a launch date.

Amazon stresses permission and customer experience

Amazon’s stated objection is narrower than opposition to artificial intelligence generally. In its statement concerning Perplexity, the company said third-party applications making purchases for customers should operate openly and respect businesses’ decisions about whether to participate.

Amazon said it had repeatedly asked Perplexity to remove Amazon from the Comet experience, citing what it described as a significantly degraded shopping and customer-service experience. That characterization is Amazon’s position, not an independently established finding.

The contrast is between an agreed integration and a disputed third-party service. It does not establish that Walmart accepts every shopping agent or that Amazon rejects every external AI partnership.

Conclusion

The practical checkpoint for Walmart’s announced integration is confirmed customer availability, which the October 2025 announcement did not date. For Amazon’s dispute, the central issue remains whether third-party agents have permission to include its shopping service.
