What the Census data shows

The Census Bureau's quarterly report puts seasonally adjusted US ecommerce at $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 reached $1,986.5 billion, up 6.7% on the year. Online took 17.1% of retail sales, up from 16.3% a year earlier according to DataPorium's reading of the same tables. The figures are not adjusted for price changes, and the Census page notes the release has since been revised, so check the November 19 report for the current series.

Why the record is bigger news than it looks

Marketplace Pulse, writing on August 27, said this was the second straight quarter of double-digit online growth after four years without one, and the fourth record share in a row. Online grew about 5% a quarter through 2025, which it ties partly to tariffs and the end of the de minimis exemption hitting the categories where online had been gaining fastest. Total retail grew at its fastest pace since 2022. In plain terms, online stopped stalling in 2026 and started taking share from stores again.

The catch: a third of it is price

Marketplace Pulse estimates that about a third of the acceleration reflects higher prices, putting real growth near 8%, roughly the 2024 rate. That is the point most coverage of the record skipped. Shoppers are paying more per order, not buying dramatically more things. A brand that raised prices to pass on tariffs can show double-digit revenue growth while selling no more units than last year.

How online share came back

  1. Online grows about 5% a quarter

  2. First double-digit quarter in four years

  3. Census: Q2 up 12.2%, 17.1% share

  4. Marketplace Pulse: a third is price

  5. Census publishes Q3 2026 data

Where the growth went

Marketplace Pulse lists the platform numbers for the same period: Walmart US online sales up 24% with advertising up 38%, while Walmart's whole US business grew 3.5%. Shopify's North American merchants sold 28% more. Amazon's own online store sales grew 15%. DataPorium adds Target's digital comparable sales up 8.7%. Against a 12.2% market, Walmart and Shopify gained share and Target's digital business lost ground, which tells brands where the extra shoppers went.

So what for a brand's P&L

The benchmark you need is not your revenue growth but your unit growth against about 8%. If your units grew less than that, you lost real share even if revenue looks fine. If your online sales grew less than 12.2% in nominal terms, you lost share outright. And if Walmart or Shopify grew faster than your Amazon business, your channel mix is drifting from where buyers are going.

Worked example with illustrative numbers

These numbers are invented to show the arithmetic. A brand sold $1,000,000 online in Q2 2025 and $1,100,000 in Q2 2026, a 10% rise. It raised average prices 6% over the year. Units therefore grew about 3.8%, because 1.10 divided by 1.06 is 1.038. The market grew 12.2% in revenue and about 8% in real terms, so the brand lost share on both measures. Holding share would have meant about $1,122,000 in revenue, or roughly $22,000 more in that one quarter.

What sellers should do before November 19

  • Finance lead: pull Q2 and Q3 units and revenue by channel and split growth into price and volume. Metric: unit growth shown next to revenue growth.
  • Amazon manager: in Seller Central Business Reports, compare units ordered with ordered product sales year on year. Metric: unit growth at or above about 8%.
  • Channel owner: compare Walmart and Shopify growth with the 24% and 28% platform rates, using our Walmart vs Amazon comparison. Metric: each channel's growth against its platform rate.
  • Pricing owner: review any price rise since 2025 against conversion rate, using our Amazon pricing strategy guide. Metric: conversion held within one point after the rise.
  • Media buyer: shift test budget toward the channel growing fastest for your category. Metric: new to brand orders per dollar by channel.
  • Owner: read the Q3 Census release on November 19 and repeat the share check. Metric: share gained or lost, written in the monthly report.

When this does not apply

The Census series covers all US retail ecommerce, so a niche category can move very differently; our coverage of Amazon clothing sales falling 12% while health rose 30% shows how wide the gap can be. Brands mostly outside the US, B2B sellers and wholesale-led brands should use their own channel benchmarks. The 8% real figure is an estimate by Marketplace Pulse, not a Census number.
