Amazon posted 15% year-over-year growth in worldwide paid units during the first quarter of 2026, the strongest volume increase the company has seen since the final months of COVID-19 lockdowns in 2021.
CEO Andy Jassy disclosed the metric in the company’s May 1 earnings release, alongside confirmation that third-party sellers now account for 60% of all units sold on the platform.
The unit growth figure stands out as a demand signal for marketplace sellers. While Amazon’s overall revenue climbed 17% to $181.5 billion, the 15% unit increase suggests volume momentum is accelerating across categories, not just in higher-priced segments or AWS cloud services.
Amazon’s Q1 Results Show Strength Across AWS, Retail, and International Markets
Amazon’s North America segment grew 12% year-over-year to reach roughly $103 billion in Q1 sales, representing 57% of total net sales. International segment revenue increased 19% on a reported basis, or 11% excluding foreign exchange fluctuations, contributing 22% of the total. AWS grew 28% and made up the remaining 21% of net sales.
Net income surged 77% to $30.3 billion in the quarter, reflecting improved operating leverage and strong demand for AWS services. The company increased its total workforce by just 1% year-over-year, a sharp contrast to the rapid hiring seen during the pandemic and subsequent layoffs in 2022 and 2023.
Third-party sellers hitting a 60% share of paid units represents a continuation of a long-term trend. Amazon has not disclosed whether this percentage ticked up from the prior quarter or year, but the figure reinforces the platform’s role as a marketplace-first business rather than a traditional first-party retailer. For context, third-party unit share hovered near 50% in the mid-2010s and crossed 58% by 2020.
Why Amazon’s Growth Is More Durable Than Its Pandemic Surge
The comparison to late-2021 lockdown levels is significant. During that period, Amazon saw explosive but unsustainable growth as consumers shifted spending online and stimulus payments fueled discretionary purchases.
Unit growth rates then decelerated sharply through 2022 and 2023 as shoppers returned to stores, inflation squeezed budgets, and the company lapped difficult comparisons.
The Q1 2026 result suggests Amazon has moved past that normalization phase. Unit growth is now accelerating on a base that is far larger than it was in 2021, which implies both broader category penetration and higher purchase frequency among existing customers.
The growth is occurring without the tailwinds of lockdowns or government stimulus, pointing instead to structural factors such as faster delivery, expanded Prime benefits, and competitive pricing relative to other channels.
Prime Day Moves to June, With Regional Exceptions
Amazon confirmed that its annual Prime Day event will take place in June 2026 for most markets, shifting earlier from its usual July timing. The company did not provide exact dates. Australia, Brazil, India, and Japan will hold Prime Day later in the summer, though no explanation was given for the regional split.
The timing change will compress the calendar for sellers preparing inventory and promotions. Brands and third-party merchants typically begin ramping stock and finalizing Lightning Deals 60 to 90 days ahead of Prime Day. A June event means those preparations are already underway, and sellers who have not yet committed inventory or advertising budgets may find themselves squeezed for time.
The shift also affects how Q2 results will be reported. Moving Prime Day forward by several weeks will pull a significant volume of sales into Q2 that would have otherwise landed in Q3, making year-over-year comparisons more complex for the next two quarters.
How Amazon’s Growth Impacts Third-Party Sellers
Strong unit growth and rising third-party share create both opportunity and pressure for marketplace sellers. Higher volume means more potential customers are browsing and buying, but it also intensifies competition for visibility in search results and sponsored placements. Sellers who can maintain or improve their organic rankings and conversion rates stand to benefit disproportionately.
The 60% third-party unit share also underscores Amazon’s dependence on marketplace sellers for selection and fulfillment capacity. This dynamic gives Amazon strong incentive to keep sellers engaged, but it also means the platform will continue extracting value through advertising, fulfillment fees, and other services. Sellers should expect ongoing fee pressure even as volume grows.
Brands selling both direct-to-consumer and through Amazon need to weigh channel strategy carefully. With unit growth running at 15%, Amazon is likely gaining share relative to other online and offline channels. Brands that under-invest in Amazon presence risk ceding category leadership to competitors who are leaning in.
What to watch in Q2 and beyond
The timing and scale of June Prime Day will be the key event to monitor. If unit growth remains elevated into Q2, it would confirm that the Q1 result was not a one-time surge but the start of a sustained acceleration. Conversely, if growth moderates after Prime Day, it may suggest the Q1 strength was driven by pent-up demand or favorable comparisons rather than structural momentum.
Sellers should also track any changes in advertising costs and competition. Higher traffic and conversion often lead to rising cost-per-click in sponsored placements as more sellers compete for the same keywords. Monitoring ACoS and total advertising cost of sale will be essential to preserving profitability even as revenue grows.
Amazon’s modest workforce growth of just 1% suggests the company is prioritizing margin expansion over capacity addition. That could mean tighter inventory limits at fulfillment centers or slower expansion of delivery infrastructure, which may constrain how quickly sellers can scale if demand continues to surge.
