Best Buy online and total sales fell year over year in its fiscal Q4, though overall revenue increased for its full-year 2026.

Across its enterprise, Best Buy generated $13.81 billion in revenue during its fiscal Q4 2026, which ended Jan. 31. That marked a 0.96% year-over-year decrease. About $12.58 billion came from the United States, down from nearly $12.72 billion the prior year.

For its fiscal full-year 2026, Best Buy revenue totaled $41.69 billion, a 0.39% year-over-year increase. Of that, almost $38.28 billion came from the U.S., up slightly from $38.24 billion in its fiscal 2025.

Similarly, comparable sales at Best Buy (those that consumers made online and in stores that were open in the prior-year period) decreased 0.8% in Q4 and increased 0.5% for the full year.

CEO Corie Barry told investors on Best Buy’s quarterly earnings call that “slightly softer customer demand” affected the retailer’s holiday quarter.

“Our holiday customer demand patterns were also different than modeled despite sales event timing that was very similar to last year’s,” Barry said. “We saw softer-than-expected sales in November and the beginning of December. We then experienced strong sales in the last two weeks of December and the start of January, and sales were negatively impacted by weather-induced store closures during the last week of the quarter.”

She added that Best Buy prepared for a promotional holiday period, and the environment was “a bit more promotional than we factored heading into the quarter.”

Best Buy is No. 8 in the Top 2000. The Top 2000 database is Digital Commerce 360’s ranking of the largest North American online retailers.

Best Buy online sales Q4 2026

In its fiscal Q4 2026, Best Buy online sales decreased 2.3% to $4.91 billion compared to the prior-year period. Furthermore, Best Buy ecommerce sales in Q4 represented 39.0% of revenue compared with 39.5% the year before.

Barry said Best Buy reached its fastest-ever fulfillment speeds for its Q4 online sales. It fulfilled 70% of online orders within two days, she added.

Barry said Best Buy will “continue strengthening our position in retail as a leading omnichannel destination for technology, while at the same time scaling new profit streams.”

She said the retailer’s priorities and resource allocation will focus on driving omnichannel experiences for customers, scaling Best Buy’s ads and marketplace, and driving efficiencies by identifying “crucial” cost reductions.

Looking back at the full fiscal year, Barry called Best Buy’s online marketplace relaunch successful. She said Best Buy onboarded more vendors than it originally expected and “drastically” increased its available SKU count. It also nearly doubles the number of ad partners it had compared to the prior year, according to Barry.

“We were able to both make the necessary investments in our marketplace and ads initiatives and expand our enterprise operating margin through a combination of disciplined expense management and efficiency optimization efforts,” she said.

Barry said the Best Buy online marketplace’s sales represented about $300 million in domestic gross merchandise volume (GMV) in Q4. Customer return rates for items on the marketplace are lower than first-party return rates, she said. And more than 80% of returns go through Best Buy’s physical stores, she added.

Through March 3, the Best Buy Marketplace has enlisted more than 1,100 sellers, she said. More than 90% of those sellers with an open storefront on the marketplace “are experiencing sales in any given week,” she added.

How Best Buy is integrating AI platforms

Barry said Best Buy is partnering with OpenAI to give consumers “a new way to explore and discover” the retailer’s products.

“We’re among the early retailers to make it easier for our product catalog to be displayed on ChatGPT, creating a more seamless path to product inspiration,” she said. “We’re also an early ads partner and exploring more opportunities to enhance our shopping experience with OpenAI.”

Best Buy is also supporting Google on the Universal Commerce Protocol (UCP). Barry called the protocol “a cross-industry standard that helps create a more seamless agentic shopping journey across the web.” Google co-developed the UCP with Shopify.

She added that using the UCP, Best Buy is working with Google to build another way for customers to purchase directly in AI Mode in Google Search and the Gemini app.

“We are also the first retail partner to launch a native checkout integration with Wizard, an AI-powered commerce platform,” she said. “As agentic commerce matures, we want to serve our customers in new ways, both on and off of platforms. That includes evolving BestBuy.com to be more agentic-friendly and ensuring our site is ready for AI agents to browse and discover on behalf of our customers.”
