The Mirakl Marketplace Map (2026): Who's Powered by Mirakl and What It Means for Sellers

Some of the best-performing content in this industry is the "complete map" guide to marketplaces by country. We're going to do something more useful for sellers: map the marketplaces that all run on the same underlying platform — Mirakl — because if you sell on one, the others become dramatically easier to reach, if your catalog data is in shape.

What Mirakl is, briefly

Founded in France in 2012, Mirakl provides the technical infrastructure that lets a retailer launch and run a third-party marketplace — seller onboarding, catalog management, orders, payments, and quality control — without building it from scratch. Today its operating system spans an enterprise marketplace platform, a multichannel selling layer (Mirakl Connect), retail media (Mirakl Ads), and agentic-commerce infrastructure (Mirakl Nexus).

The scale in 2026

The ecosystem now includes more than 450 marketplace operators worldwide and over 100,000 third-party sellers. Operators include household names: Macy's, Decathlon, Carrefour, Nordstrom, Best Buy, Kroger, Leroy Merlin, Maisons du Monde, and Galeries Lafayette, plus B2B giants like Airbus Helicopters and Sonepar. The platform runs at enterprise-grade scale, having processed tens of billions of product updates during peak periods while maintaining near-perfect uptime.

Why the "same platform" point matters to you

Here's the seller insight most country-by-country maps miss. Because so many large retailers run on Mirakl, breaking into one well-run Mirakl marketplace builds the exact capability you need for the next: clean, complete, correctly-mapped product data.

But — and this is the catch — Mirakl is the platform, not a single shared catalog standard. Each operator configures its own required attributes and its own taxonomy. So the data discipline transfers, but the specific field-by-field work does not. You still have to meet each operator's spec.

The data problem, stated plainly

To sell across, say, Macy's and Decathlon and Best Buy's Mirakl marketplaces at once, you need the same products expressed three different ways — three taxonomies, three attribute sets, three validation passes. Multiply by your SKU count and you can see why catalogs get stuck.

Where SYNAPS comes in

SYNAPS treats this as one job, not three. From minimal input it enriches each product's attributes, maps it to each operator's taxonomy, and validates it against each destination's requirements before submission — so a single source catalog can go live correctly across many Mirakl marketplaces at once. It then monitors daily, so when an operator changes its spec, you're not the last to find out via a wave of rejections.

That's the difference between having access to 450+ marketplaces and actually being live on the ones that matter to you.
