Walmart Sparky Explained: The AI Shopping Assistant and the Pricing Debate

Walmart Sparky has quickly become one of the most closely watched AI shopping assistants in the US. After all, it sits inside the app of the country’s largest retailer. Walmart also says its use is growing fast. Now it is also at the center of two public debates: whether AI shopping tools could enable personalized pricing, and whether they present product information fairly.

This guide explains what Sparky does, where you can use it, what Walmart has said about data and prices, and what the September 2026 scrutiny is about. It is based on Walmart’s own documentation, company statements and news reports checked in September 2026. We haven’t tested Sparky for this article.

What is Walmart Sparky?

Sparky is a generative AI assistant built by Walmart. According to Walmart’s June 6, 2025 announcement, it helps customers search for items, summarize product reviews and get recommendations for occasions across every product category.

For example, Walmart’s help page suggests requests such as finding “the best laptop for an art student” or gift ideas. To open it, you tap the smiley-face icon in the Walmart app’s bottom menu while signed in. Walmart describes it as available to US customers.

Walmart also presents Sparky as part of a wider shift to what it calls agentic commerce. In other words, the aim is an assistant that eventually acts for you, not just one that answers questions.

What can Sparky do today?

Based on Walmart’s documentation, Sparky’s main jobs are:

• Finding products from a plain-English description.
• Comparing products and answering detailed questions about them.
• Summarizing customer reviews.
• Suggesting items for an event or occasion, such as clothes for the weather.

When it launched, Walmart also listed plans to let Sparky reorder household essentials, book services, plan meals and add ingredients to your cart, and help plan events within a budget. It said Sparky would eventually accept text, images, audio and video. However, those were plans at the time, so check the app for what is live in your account.

Walmart Sparky in ChatGPT and Gemini

Today, Sparky no longer lives only in Walmart’s app. In January 2026, Walmart and Google announced a partnership to bring Walmart and Sam’s Club products into conversations in Gemini, starting in the US.

Then, in March 2026, Walmart launched an app experience powered by Sparky inside ChatGPT. According to Retail Dive, it covers the full journey from product discovery through account linking, loyalty and payment, starting on the web.

Meanwhile, that move came as OpenAI changed course on shopping. OpenAI had launched Instant Checkout, which let people buy inside ChatGPT, in September 2025. In March 2026, it said the first version “did not offer the level of flexibility that we aspire to provide”, and it began letting merchants use their own checkout. Axios reported that Walmart’s in-chat conversions had been “three times lower” than purchases that sent shoppers to its website.

Where	What Sparky does there	Checkout
—	—	—
Walmart app	Search, compare, review summaries, recommendations	Walmart
ChatGPT	Walmart shopping experience powered by Sparky	Walmart’s own flow, with account linking
Gemini	Walmart and Sam’s Club products in conversations	Linked to Walmart’s delivery and membership

How popular is Sparky?

So far, Walmart has shared several numbers on its earnings calls. In May 2026, Digital Commerce 360 reported that Walmart’s CEO, John Furner, said weekly active users had risen more than 100% in a single quarter. He also said Sparky users’ average order value was about 35% higher than that of non-users.

The same report quoted a Walmart US executive saying units bought through Sparky had grown to more than four times the previous quarter’s level. Then, on September 28, 2026, Retail Dive reported updated figures: usage up 70% year on year, and Sparky users spending 40% more per order than non-users.

Note that these are company figures, and higher spending among Sparky users doesn’t prove that Sparky causes it. Keen shoppers may simply be more likely to try new tools. Still, the numbers show why Walmart is investing heavily.

Does Walmart Sparky change prices based on who you are?

This question moved to the front in September 2026. On September 28, Retail Dive reported that Furner had published a letter denying that Walmart uses its digital shelf labels or Sparky for personalized pricing. He wrote: “We don’t set different prices based on who you are or the time of day, and we won’t.”

According to Retail Dive, Furner also pledged that Walmart won’t use Sparky data to raise prices or hide lower-priced items. That is a public commitment, so it becomes easier to hold the company to.

Still, critics remain wary. Retail Dive noted that Walmart holds a 2023 patent for electronic shelf label technology that could adjust prices, for example based on items in a shopper’s cart. Lindsay Owens, president of the advocacy group Groundwork Collaborative, argued that Walmart wouldn’t build such technology unless it “padded their profits”. A patent, however, doesn’t show that a company uses the method.

Why US senators asked the FTC to look at Walmart Sparky

Separately, on September 21, 2026, reports said Senators Tammy Baldwin and Rick Scott had asked the Federal Trade Commission to examine Sparky. In particular, they asked whether it reliably helps shoppers identify American-made products. They also asked whether “potentially questionable country-of-origin claims are clearly surfaced”.

For that reason, it is important to be precise here. A request from senators is not an FTC ruling, an investigation finding or a determination that Walmart broke any law. Instead, it reflects a wider question about AI shopping: an assistant is only as reliable as the product data behind it.

Sparky and your data

Walmart’s help page says Sparky uses “limited customer data” to make recommendations, under Walmart’s privacy policy. It also warns that “mistakes can happen” and asks users not to rely on Sparky for medical, legal or financial advice.

Also, if you use Sparky inside ChatGPT or Gemini, another company’s terms apply to your conversation. So it is worth checking what you have linked. Our guide to reviewing apps connected to your accounts explains how, and our guide to AI agent memory covers what assistants remember.

How to use Sparky sensibly

Sparky can save time, especially for quick comparisons. A few habits keep you in control.

1. Give a budget in your request, for example “a coffee maker under $60 with good reviews”.
2. Ask for two or three options instead of one answer.
3. Open each product page and check the price, seller and delivery date.
4. Read a few full reviews yourself, since summaries can miss patterns.
5. For country of origin, check the product page and packaging details.
6. Compare with another retailer for big purchases.

These steps apply to any retailer’s assistant, not just Walmart’s. For a broader view, see our guide to AI shopping agents.

Walmart Sparky vs other retailer assistants

Walmart isn’t alone. Most large retailers now offer an assistant, and they share strengths and limits.

Assistant	Retailer	Where it runs
—	—	—
Walmart Sparky	Sam’s Club and Walmart	Its own app, ChatGPT, Gemini
Alexa for Shopping	Amazon	Amazon app and Alexa devices
Branded site agents	Many retailers	Retailers’ own websites

Amazon, for instance, replaced its Rufus assistant with Alexa for Shopping in May 2026, according to CNBC. Our guide to Alexa for Shopping explains that tool. Similarly, Salesforce predicts that one in three ecommerce sites will run their own shopping agent by Cyber Week 2026.

In the end, the common thread is simple. Each assistant knows its own store best, so none of them replaces comparison shopping across retailers.

Who should use Walmart Sparky?

Naturally, regular Walmart shoppers who already use the app will get the most from it. It suits quick product searches, gift ideas and comparisons between similar items.

On the other hand, if you want neutral advice across many retailers, a store’s own assistant has an obvious limit: it recommends that store’s products. Keep that in mind, and treat Walmart Sparky as a helpful shop assistant rather than an independent adviser.
