E-commerce is still taking a larger share of retail spending

Accelerating Updated September 18, 2026 · High confidence

What changed

U.S. retail e-commerce sales were an estimated $340.2 billion in the second quarter of 2026, up 3.8% from the first quarter and 12.2% from a year earlier. Total retail sales rose 6.7% year over year. E-commerce accounted for 17.1% of retail sales on a seasonally adjusted basis.

Online sales are still growing faster than retail overall.

Why it matters

For a store-based retailer, online and in-store sales are often part of the same customer journey. Someone may discover a product online, see it in person, reorder on a phone and return it at the store. The harder question is whether those handoffs are easy and profitable.

Online-only retailers face a different problem. More demand is moving online, but more competitors are chasing it, which puts pressure on acquisition cost, fulfillment and retention.

What it means for your business

Know your own digital share, but do not chase 17.1% just because that is the national number. A local furniture store and an online beauty retailer should not look the same.

Track online traffic, conversion, returns, fulfillment cost and how many customers buy through more than one channel. Then fix one cross-channel annoyance at a time: inventory visibility, pickup, returns, replenishment reminders or a better post-purchase flow. For online-only businesses, put repeat purchase and contribution after fulfillment ahead of headline revenue growth.

What to watch

Watch the third-quarter e-commerce share, your digital conversion rate, returns, customer acquisition cost and repeat purchase. Growth that gets eaten by shipping, returns or paid acquisition is not much of a win.
