GMV Is a Vanity Metric. Here's What Fashion Marketplaces Are Hiding.

Quick Facts

GMV excludes returns, refunds, discounts, and fees, making it a poor proxy for actual business health.
Farfetch collapsed after years of GMV-led reporting, with gross margins falling and losses mounting despite strong volume numbers.
Public marketplaces traded at a median 2.3x EV/Revenue in 2025, down sharply from a long-term average of 5.6x, reflecting investor skepticism of top-line growth stories.

Every marketplace has a big GMV number. Few have a profitable business. Gross merchandise volume, the total value of all goods sold through a platform in a given period, has become the dominant metric for measuring marketplace scale. Investors see it. Founders pitch it. Press releases lead with it.

But GMV is not revenue. It is not profit. And it is not standardized.

The Gap Between GMV and Revenue

For a marketplace, GMV counts every dollar a buyer pays. The platform keeps only its commission or take rate. Shopify processed roughly $378 billion in GMV in a recent fiscal year and recorded approximately $11.6 billion in revenue, a gap of more than 30x. The platform earns primarily through subscriptions and payment processing, not merchandise sales.

A simpler example: if a fashion marketplace records $100,000 in GMV and charges a 15% commission, its actual revenue is $15,000. That $15,000 is what appears on an income statement. GMV does not.

Returns Make the Problem Worse

Online return rates average 19% to 20% across all categories, according to the National Retail Federation’s 2025 Retail Returns Landscape report. Apparel runs higher, between 20% and 40%. Footwear ranges from 17% to 31%.

Returns are typically counted in GMV before they are processed. Nationally, shoppers were expected to return nearly $850 billion in merchandise in 2025. Every one of those dollars was recorded in a GMV figure somewhere before the refund was issued.

No Standard Definition

GMV sits outside generally accepted accounting principles. There is no regulatory requirement for how it is calculated or what it must include. Companies define their own scope. One platform may count canceled orders. Another may net out returns. A third may include seller fees in the total.

Research on public marketplace valuations shows that valuation multiples using GMV carry a variance of 13x, meaning the highest multiple divided by the lowest is 13 times larger. For gross profit multiples, that variance drops to 2x. Comparing two marketplaces using GMV multiples is, by that measure, close to meaningless.

The Farfetch Warning

Farfetch is the clearest cautionary tale in fashion. CEO Jose Neves declared 2023 would be a great year, citing strong GMV growth and a path to adjusted EBITDA profitability. Gross profit margins had already fallen from 46.2% in Q2 2022 to 42.5% in 2023. Losses continued. The company sold to South Korean retailer Coupang in late 2023 in a distressed deal after its stock collapsed.

DoorDash followed a similar arc. When it went public in December 2020 at a $72 billion valuation, analysts pointed to $24.7 billion in GMV to justify the price. By 2024, the stock had fallen more than 60% from its peak.

What Operators Should Track Instead

For marketplace founders and operators, GMV is not worthless. It measures transaction flow and platform scale. But it should never travel alone.

Take rate, the percentage of GMV the platform actually retains as revenue, tells you how the business monetizes volume. Contribution margin, revenue minus variable costs, tells you whether growth is accretive or destructive. Active buyer counts and repeat purchase rates reveal whether demand is sticky or manufactured through discounts.

A marketplace with a negative contribution margin grows its losses in direct proportion to GMV. Scaling that business accelerates the problem. Investors in 2025 appear to understand this. Public marketplaces traded at a median 2.3x EV/Revenue this year, down from a long-term average of 5.6x. The era of valuing businesses on GMV multiples has narrowed sharply.

The apparel resale market reached $202.98 billion in 2025, up from $181.4 billion in 2024, a compound annual growth rate of 11.9%. That growth is real. Whether the platforms capturing it are building durable businesses depends on metrics that GMV alone cannot answer.
