Short answer: Walmart Sparky is Walmart's AI shopping assistant, and from this holiday season it does more of the product choosing for US shoppers. Since its October 30, 2026 update, Sparky can turn a photo of a shopping list into a cart, suggest products from a photo, plan recipes and suggest gifts. On October 21, Walmart also announced Agent Profiles, which let outside AI agents buy on Walmart within limits the customer sets. For Marketplace sellers, the move is clear: make your listings easy for AI to read and trust. That means complete attributes, competitive prices, fast shipping, steady stock and strong reviews, which are the same five things Walmart's Listing Quality score already measures.
This is a US story. Walmart.com doesn't operate in the UK or EU, and the new features below are live for US customers first.
What is Walmart Sparky?
Sparky is the AI assistant inside the Walmart app, on Walmart.com and in Walmart stores. Shoppers ask it questions in plain language, and it recommends products sold at Walmart, drawing on product details and reviews.
It is growing fast. According to Retail Dive, Sparky's usage is up 70% since its June 2025 debut. Walmart CEO John Furner said in August that customers who use Sparky spend 40% more per order than those who don't. US CEO David Guggina said visual search drove a 57% conversion increase compared with text search.
Those are Walmart's numbers, not independent research, but the direction is plain: more Walmart shoppers are letting an AI shortlist products for them. If you've followed what happened on Amazon when Rufus was replaced by Alexa for Shopping, this will look familiar.
What's new in Sparky for the 2026 holidays
Walmart's October 30 announcement added these features. All are available to US customers now, except voice:
| Feature | What the shopper does | What it means for sellers |
|---|---|---|
| List to cart | Photographs a handwritten list or exports a notes list; Sparky builds the cart | Generic list items ("dish soap", "AA batteries") get matched to specific products. Clear product names and attributes help you get matched |
| Photo problem-solving | Uploads a photo of a problem, like a stained tablecloth | Sparky has to connect a problem to a product. Your listing needs to say what problem it solves |
| Recipe planning | Asks for a meal plan on a budget; Sparky adds ingredients to the cart | Price and size data decide whether you fit a budget |
| Healthier swaps | Asks for lower-sugar or better-for-you versions | Nutrition and ingredient attributes need to be filled in and accurate |
| Gift suggestions | Describes the person, their interests, age and budget | Use cases, age ranges and gift context in your content |
| Shop to Light | Finds an item on a store map and flashes its shelf label | In-store only; mostly relevant to first-party suppliers |
| Spanish and French | Types or speaks in either language | Rolling out with the Canada and Mexico expansion |
| Voice | Speaks to Sparky | Expected chainwide by the end of 2026, not live yet |
Walmart says it plans to scale Sparky to Canada, Mexico and Sam's Club members in the US.
Walmart Agent Profiles and Agent Gateway, explained
Sparky is Walmart's own agent. The October 21 announcement is about everyone else's: ChatGPT-style assistants and other AI agents that shoppers may send to Walmart to buy for them.
Walmart announced three things:
- Agent Profiles. Each AI agent a customer authorizes gets its own profile in their Walmart or Sam's Club account. The customer can approve every purchase or set a spending limit; Walmart's examples were $50, $100 and $200. Agent purchases show separately, and the customer can delete the profile at any time. Walmart said this would launch within the next month.
- Walmart Agent Gateway. A direct connection for AI agents built on the Model Context Protocol (MCP). It covers product discovery, adding to cart, purchasing and order tracking. It is an invitation-only beta for companies and developers, and Walmart hasn't named the participants.
- Rules for agents. Customer approval is required by default. Agents never receive payment card details, can't change payment methods, must act only within what the shopper asked, and must identify themselves. Agents that break the terms can be blocked.
Walmart also says agents see the same prices a person sees, with offers and fees shown before purchase.
Why this matters to you: an agent working through the Gateway doesn't scroll a search results page or look at your main image the way a person does. It reads structured product data, compares price and delivery, and picks. Digital Commerce 360 reported that Manish Joneja, Walmart's senior VP of Global Marketplace and Fulfillment Services, called agentic shopping a potential game-changer that could help lesser-known brands reach customers. The same report says Walmart is working with Marketplace sellers on listing and catalog quality so AI tools can understand and recommend their products. If you're new to the idea, start with our explainer on what agentic commerce is.
How Sparky and AI agents decide what to recommend
Walmart hasn't published how Sparky ranks products, and we won't pretend to know the formula. But Walmart does publish what it considers a quality listing. Its Listing Quality score, in Seller Center, has five parts:
- Content quality: item name, description, key features and images.
- Price competitiveness: your price compared with similar products on other marketplaces.
- Shipping: your promised delivery speed across ZIP codes.
- Published and in stock: how often the item was available over the last seven days.
- Ratings and reviews: how many reviews you have and the average rating.
Walmart says quality listings drive higher conversion and visibility and can help unlock the Pro Seller badge. Every one of these signals is also something an AI assistant needs to answer a shopper's question well: Is it the right product? Is it a fair price? Will it arrive in time? Is it in stock? Do people like it?
So the practical rule is simple: optimize for the Listing Quality score and for clear, factual content, and you're optimizing for Sparky and outside agents at the same time.
Walmart Sparky checklist for Marketplace sellers
Work through this on your top 20 items first, then the rest of the catalog.
- Check your Listing Quality dashboard. Sort by your best sellers and fix the lowest-scoring items first. Use the Bulk Attribute Editor to update names, descriptions, key features and images across many items at once.
- Fill every relevant attribute. Size, count, flavor, material, age range, ingredients, compatibility. When a shopper asks Sparky for "a lower-sugar cereal for kids", attributes are how a product qualifies. Blank fields are invisible to AI.
- Write key features as plain answers. "Removes red wine stains from cotton and polyester" beats "Powerful cleaning formula". Say what problem the product solves, for whom, and in what situation.
- Make product names specific. Brand, product type, key variant and size. List-to-cart matching works from short phrases like "paper towels", so the product type should be obvious from the name.
- Check price competitiveness. Walmart compares your price with other marketplaces. Use the Pricing insights dashboard. An agent with a $50 budget can't pick a product it can't afford.
- Speed up delivery. Shipping speed is part of the score, and Sparky highlights fast delivery. If your own shipping is slow, look at Walmart Fulfillment Services (WFS).
- Stay in stock through December. The in-stock signal looks at the last seven days, so running out during peak weeks hurts you right when AI traffic is highest.
- Build reviews the legitimate way. Sparky draws on reviews, and review count and rating feed the score. Follow Walmart's Marketplace review guidelines; never incentivize reviews.
- Keep your Amazon and Walmart content consistent but not copied blindly. Walmart's fields and limits differ. Map each Amazon field to the right Walmart attribute instead of pasting one long block of text.
The same "write for the answer engine" approach applies across channels. Our guides to AI SEO for Shopify and AEO cover how ChatGPT, Gemini and Copilot pick products off your own site.
Can you advertise inside Sparky?
Walmart Connect has been testing ads in Sparky since early 2026. Adweek reported in January that ads may appear as a sponsored prompt when shoppers ask Sparky for product recommendations, following an initial test in fall 2025. Walmart hasn't published broad, self-serve availability for Marketplace sellers.
For now, treat Sparky ads as something to ask your Walmart Connect contact about, not a budget line. Your regular Sponsored Products campaigns still run on Walmart search, and the better your listing quality, the better those ads convert too.
Sparky, ChatGPT and Gemini: where Walmart shoppers use AI
Walmart is spreading its AI shopping across several surfaces. Retail Dive reports that Walmart brought a Sparky-backed experience to ChatGPT earlier in 2026 and has integrated with Google Gemini, and the October tools open the door to more outside agents. The details of each integration change often, so don't build a separate strategy for each one. The data they all read is your Walmart listing. Get that right once and it works everywhere Walmart products are surfaced.
The bottom line
AI is starting to make the shortlist on Walmart. Sparky now builds carts from photos and lists for US shoppers, and Agent Profiles will let outside agents buy within customer-set limits. Neither rewards clever ad copy. They reward complete, accurate, well-priced, in-stock listings with good reviews and fast delivery.
Start with your best sellers this week: fix attributes and key features, check price and delivery, and lock in stock for December.
