Walmart is abandoning OpenAI's direct "Instant Checkout" integration in favor of embedding its proprietary Sparky chatbot directly into ChatGPT and Google Gemini, following disappointing sales performance. The strategic shift, confirmed by Walmart executive vice president Daniel Danker, reveals fundamental challenges with the current implementation of autonomous AI shopping agents.
What Failed: The Instant Checkout Experiment
Since November, Walmart had allowed ChatGPT users to purchase approximately 200,000 products directly within OpenAI's chatbot interface through a feature called Instant Checkout. The system required users to provide shipping and payment details to OpenAI once, enabling purchases without leaving ChatGPT.
According to Danker, who oversees design and product for Walmart, conversion rates for products sold directly inside ChatGPT were three times lower than for items that required users to click out to Walmart's website. For higher-ticket items like televisions, shoppers still needed to complete purchases through traditional web channels.
"Put simply, Instant Checkout has been a flop," Danker told WIRED, describing the consumer experience as "unsatisfying."
The Core Problem: Fragmented Checkout Experience
The primary issue with Instant Checkout, according to Walmart's analysis, was its forced single-item purchasing model. "They fear that when checkout happens automatically after every single item that they're going to receive five boxes when they actually just want it all in one," Danker explained. "They generally don't want to split the checkout experience, where it buys the one item, even though they had other items in their Walmart cart already."
This fragmentation contradicted typical shopping behavior where consumers add items to a cart over multiple sessions before completing a single purchase.
The New Approach: Sparky Inside ChatGPT and Gemini
Starting next week, Walmart will deploy its Sparky chatbot within ChatGPT, creating what Danker describes as "essentially a chatbot inside a chatbot." A similar integration will launch in Google's Gemini chatbot next month.
The new system addresses the checkout fragmentation problem by syncing users' shopping baskets across platforms. When users first encounter Sparky within ChatGPT, they'll log into their Walmart account. Their basket from Walmart's website or app will then sync with their ChatGPT session, allowing them to add items over time before completing a single checkout.
What Actually Sold Through Instant Checkout
Despite the overall poor performance, some product categories showed traction in the Instant Checkout experiment:
- Vitamin and protein supplements were top sellers
- GLP-1 weight-loss drug information seekers received ChatGPT advice to increase nutrient intake, leading to supplement purchases
- Higher-priced items that avoided shipping or small-basket fees performed better
- Automotive, beauty, home management, hardware, and tools categories accounted for over half of Instant Checkout orders
Business Context: OpenAI's Revenue Strategy
The Instant Checkout feature was part of OpenAI's broader "agentic commerce" initiative launched last year, where the company partnered with Walmart, Etsy, and other retailers. OpenAI's business model involved charging commissions on purchases made through ChatGPT, representing a potential new revenue stream beyond subscription fees.
Danker credited OpenAI for quickly pivoting rather than spending years trying to fix the Instant Checkout experience. The shift to embedding Sparky represents a return to Walmart's preferred approach of maintaining control over the shopping experience while leveraging third-party AI platforms for discovery and engagement.
Technical Implementation Details
The new integration requires:
- User authentication between Walmart and OpenAI/Google systems
- Real-time cart synchronization across web, mobile app, and chatbot interfaces
- Maintained payment and shipping profiles within Walmart's systems rather than OpenAI's
- Unified checkout flow that respects multi-item, multi-session shopping patterns
This approach keeps sensitive customer data and transaction processing within Walmart's infrastructure while using ChatGPT and Gemini as conversational interfaces for product discovery and cart management.
