Walmart’s AI Push and the New Battle for Product Discovery

Product Discovery Is Rewriting the Rules of E-Commerce

E-commerce has entered a new phase. Price, assortment, and delivery speed still matter, but they no longer determine winners on their own. As digital shelves expand and shoppers face increasing choice fatigue, the ability to guide customers quickly to relevant products is becoming a core competitive advantage.

Research from Salesforce and McKinsey shows that shoppers are increasingly open to AI-assisted discovery, especially when it reduces effort and improves confidence. Conversational interfaces, product summaries, and contextual recommendations are beginning to replace traditional keyword search. In this environment, whoever controls product discovery has an outsized influence on conversion.

This shift has sharpened the competitive dynamic between Walmart and Amazon.

Different Starting Lines, Different Strengths

Amazon and Walmart arrived at this moment from very different places. Amazon was built as a technology-first company, with retail as its primary application. Its recommendation engines and personalization systems have been refined for decades, supported by a vast and growing marketplace.

Walmart’s foundation is operational scale. When Doug McMillon became CEO in 2014, Walmart lagged Amazon in digital commerce and data capabilities, a reality acknowledged by investors and analysts at the time. Over the past decade, Walmart invested heavily in e-commerce, marketplace expansion, omnichannel fulfillment, and retail media. AI now represents the next stage of that transformation.

Walmart’s AI Strategy Extends Beyond the Shopper

Walmart’s introduction of Sparky, its generative AI shopping assistant, marked a visible shift in how the company approaches digital discovery. Sparky helps shoppers compare products, summarize reviews, and answer questions across categories. Walmart leadership has positioned it as foundational infrastructure rather than a short-term feature.

Equally important are Walmart’s internal AI deployments. The company has announced multiple AI agents designed to support employees, developers, and supply chain partners. These tools focus on consolidating workflows, improving decision speed, and driving operational efficiency. For suppliers, stronger internal systems often translate into better in-stock performance, cleaner execution, and faster iteration online and in stores.

Industry analysts have noted that Walmart’s AI strategy stands out for its breadth, touching consumer experience and internal operations at the same time.

Amazon’s Lead and Its Guarded Approach

Amazon continues to set the benchmark for AI-driven commerce. The company has shared that its generative shopping assistant, Rufus, is used by hundreds of millions of customers and is associated with higher conversion rates and billions of dollars in incremental sales. These disclosures align with Amazon’s long-standing strength in data-driven retail.

Where Amazon differs from Walmart is in its ecosystem strategy. Amazon has largely restricted third-party AI agents from directly interacting with its marketplace. External tools are not allowed to freely scrape data or complete transactions on Amazon’s platform. This approach protects Amazon’s data advantage but limits experimentation at a time when consumer behavior is shifting.

Amazon leadership has recently indicated openness to future partnerships, but analysts continue to view the company’s approach as more cautious than Walmart’s.

Open Versus Closed Is a Strategic Choice

Walmart’s willingness to work with external AI platforms reflects a belief that innovation will come from multiple systems working together. This mirrors broader trends in enterprise technology, where open ecosystems often move faster during periods of change.

For suppliers and sellers, openness can create more ways to influence discovery through richer content, better data integration, and new shopper touchpoints. It also requires discipline and strong governance, which Walmart appears prepared to manage in exchange for speed and learning.

Personalization Will Decide the Outcome

Despite the attention on chat interfaces, personalization remains the true test. Generic recommendations do not build trust or loyalty. Effective AI must understand intent, context, and history and connect those signals to massive assortments in real time.

Walmart’s advantage lies in the diversity of its data. Few retailers operate at meaningful scale across grocery, general merchandise, physical stores, and digital commerce. If Walmart can responsibly unify those signals, it has the potential to deliver personalization that rivals, and in some cases exceeds, what pure-play e-commerce platforms can offer.

Execution risk remains high, but the opportunity is real.

What This Means for Walmart Suppliers and Sellers

For Walmart suppliers and sellers, AI-driven discovery raises the bar. Product data quality, imagery, reviews, and availability signals become even more critical when algorithms guide shoppers before they ever see a results page.

It also increases the need for alignment across merchandising, retail media, supply chain, and digital shelf teams. AI systems amplify both strengths and weaknesses. Inconsistent execution in one area can quickly undermine performance everywhere else.

Suppliers who understand how Walmart’s AI tools prioritize relevance and surface products will be better positioned as these systems evolve.

A Narrowing but Real Gap

Amazon still holds advantages in scale, institutional knowledge, and proven AI monetization. Walmart, however, has shown unusual urgency and scope in its recent AI investments. The question is not whether Walmart will replace Amazon, but whether it can materially change how discovery works within its ecosystem.

Product discovery is where that answer will become visible.

What Comes Next for Walmart’s AI Strategy

AI is no longer a side experiment in retail. It is becoming core infrastructure. Walmart’s recent moves suggest a company intent on shaping its future rather than reacting to it.

For suppliers navigating Walmart’s platform, understanding this shift is no longer optional. The mechanics of discovery are changing, and with them, the rules for winning on Walmart’s digital shelf.
