Winning the Last Mile: What Walmart’s Race for Faster Delivery Means for Suppliers and Sellers

The Next Frontier: Ultra-Fast Fulfillment at Scale

Walmart’s latest announcements make one thing clear: Delivery speed is now a critical part of winning shopper loyalty — and it’s becoming just as important as price, assortment, and convenience.

At Walmart’s recent 2025 Investment Community Meeting, CEO Doug McMillon outlined bold plans to make ultra-fast delivery a standard expectation, not a premium service. Today, Walmart can deliver same-day to 93% of U.S. households — and aims to push that number to 95% by the end of this year.

But Walmart isn’t stopping at same-day. The retailer is piloting 30-minute delivery programs in select markets, inspired by successful models already operating internationally in cities like Shanghai and Mexico City.

For suppliers and marketplace sellers, this shift means more than faster shipments — it signals the need to rethink inventory placement, product readiness, and promotional timing in ways that align with Walmart’s increasingly dynamic fulfillment capabilities.

A Tech-Driven, Dynamic Fulfillment Network

Walmart’s rollout isn’t just about putting more drivers on the road. It’s built on a next-generation fulfillment model, using geospatial AI to dynamically adjust service areas based on real-time conditions like store labor availability, traffic patterns, and inventory levels.

This means that inventory accuracy, localized demand forecasting, and assortment precision at the store level are becoming even more critical for suppliers. Products that are well-stocked and well-positioned to serve dynamic local zones will have a direct advantage in meeting — and exceeding — shopper expectations for immediacy.

One-third of Walmart’s current store-fulfilled orders already involve customers paying extra for three-hour delivery windows. As premium fast delivery becomes more mainstream, expect the winners to be those brands that can deliver right-time, right-place availability — not just in DCs, but closer to the customer, at the store level.

Drone Delivery: Moving From Pilot to Playbook

Walmart has completed over 120,000 drone deliveries and continues to expand its drone service footprint. Drones are ideal for lightweight, high-frequency items — categories like health and wellness, baby care, and household essentials.

As drone delivery becomes more normalized, suppliers in eligible categories should start considering how packaging, SKU sizing, and replenishment strategies might need to evolve to better align with drone delivery requirements.

Early movers who optimize for weight, volume, and packaging integrity could find themselves prioritized for faster, innovative last-mile programs that Walmart continues to scale.

Why This Matters to Your Growth at Walmart

Here’s what Walmart suppliers and sellers need to keep in mind:

• Localized Speed Wins: Products available closest to the customer will earn faster delivery options — and likely, higher conversion rates.
• Operational Readiness Will Separate Leaders: Walmart’s use of geospatial optimization means that lagging inventory updates, poor in-store availability, and inaccurate demand forecasts will hurt sales — more visibly than ever.
• New Promotions and Launch Windows Are Possible: With ultra-fast fulfillment capabilities, sellers can imagine new kinds of promotions (e.g., “delivered in 30 minutes!”) that were previously impossible outside of food delivery platforms.
• Category Leaders Will Shift: Fast-moving, lighter-weight, high-repeat categories stand to benefit first. If you operate in these categories, now is the time to work with your Walmart merchant teams to plan for how faster delivery could impact your pricing, promotions, and packaging.

According to McKinsey, 50% of consumers already consider same-day delivery a core buying driver. Walmart is working hard to set — and then beat — that standard. If you’re ready, you can ride this wave to faster sales velocity and deeper shopper loyalty.

Final Thoughts

Walmart’s investments in ultra-fast delivery aren’t just about speed — they’re about resetting the playing field. Suppliers and sellers that align their strategies to Walmart’s new fulfillment realities will be best positioned to win as the race for the last mile intensifies.

The opportunity is enormous — if you’re ready to move at the speed of Walmart.
