The 2025 Holiday Season Tested Retail Execution: What Retailers Need to Know for 2026

During the 2025 holiday season, fulfillment became far more visible than many retailers expected. Economic uncertainty shaped conservative planning assumptions heading into peak season, however, once the season was underway, execution mattered more than forecasts. Why? Because consumer demand didn’t soften. In fact, Adobe Analytics reported more than $10 million in online spend every minute on Cyber Monday, and the National Retail Federation reported holiday spending surpassed $1 trillion. When volume surged, fulfillment performance was the difference between meeting customer expectations and missing them.

Joint survey data from Radial and Locus Robotics offers a clear look at how consumers experienced the holidays, including the areas where they felt the most friction. Based on those insights, three clear priorities emerged for brands and retailers' 2026 strategic planning.

1. Confidence was high but narrowed the margin of error.

Consumers entered the holiday season feeling confident (over 91 percent) in retailers’ ability to handle holiday demand. However, that confidence translated into higher expectations, not patience.

Younger shoppers placed greater emphasis on speed and on-time delivery, while older generations were more focused on value and price sensitivity. Specifically, 57 percent of millennials and 54 percent of Gen Z consumers reported that getting their orders on the promised date was most important to them, compared to baby boomers (63 percent) and Gen X (59 percent), who focused on getting the lowest possible prices.

For retailers, the message is clear: consumer expectations are not one-size-fits all. Planning fulfillment strategies around average service levels leaves little wiggle room to meet the evolving uncertainty and high expectations of today’s unique consumer groups.

2. Delivery delays exposed fragile execution models.

Despite careful planning, delivery disruptions surfaced early across the industry. Nearly half (44 percent) of U.S. shoppers reported experiencing late deliveries, with Gen Z (61 percent) and parents (55 percent) feeling the impact most acutely. These groups also reported higher levels of delivery-related stress (28 percent and 22 percent, respectively), underscoring how heavily they rely on e-commerce to check items off their lists.

These results point to a broader issue: fulfillment models are optimized for peak capacity rather than resilience. When disruptions occur, whether due to lack of labor, carrier issues, weather disruptions or volume surges, retailers struggle to adapt quickly enough to protect the consumer experience.

3. Automation trust is growing, but with conditions.

Overall, shoppers were split on whether artificial intelligence and automation improved their confidence in retailers’ ability to deliver, with 38 percent saying it does and 39 percent saying it doesn’t. Younger consumers and parents were more optimistic, while older shoppers remained skeptical, demonstrating that trust in automation is still developing.

Across all demographics, fulfillment accuracy is highest when humans and automation work together (40 percent), particularly in situations where errors could directly impact the customer experience. This emphasizes the value of pairing machine efficiency with human expertise where accuracy matters most.

What This Means for 2026

Fulfillment is no longer just a back-end function. It’s become a core part of the consumer experience, shaping trust, loyalty, and repeat business.

Looking ahead, retailers have three strategic opportunities to strengthen their approach to warehouse automation:

• Plan for variability, not just peaks. The ability to adjust fulfillment velocity in real time matters more than static capacity planning.
• Design for segments, not averages. Speed, price and reliability expectations vary widely by shopper type and must be operationalized accordingly.
• Invest in flexibility-first execution. Flexible fulfillment models that blend people and automation allow retailers to scale up or down without sacrificing accuracy, experience, or operational confidence.

As geopolitical tensions, labor pressures, and economic uncertainty continue into 2026, fulfillment will remain a defining element of retail performance. Retailers that treat fulfillment as a living, adaptable system rather than a fixed logistics process will be best positioned to protect loyalty and differentiate their brand. Those that don’t risk losing customers, not because of product or price, but because they can’t consistently deliver on the promise from click to delivery.
