Best Buy’s Mirakl-Powered Marketplace

What does Best Buy’s new Mirakl-powered marketplace mean for third-party sellers? The short answer is: it opens up a Walmart-style expansion in the U.S. and beyond, allowing sellers to list products across more categories while benefiting from Mirakl’s powerful eCommerce platform. For retailers and brands alike, this represents a huge opportunity to reach millions of customers while aligning with a curated, tech-first retail strategy.

Here, we’ll take a look at how exactly you can make the most of this marketplace – and the best way to go about it.

Why is Best Buy Expanding its Marketplace?

Best Buy has traditionally been known for tech and consumer electronics – both of which, it’s fair to say, it has successfully mastered. Now, with its Mirakl integration, Best Buy is expanding into new product categories, including Home, Outdoor, Health, and Lifestyle …to name just a few. 

This mirrors strategies seen in marketplaces like Macy’s, where curated product expansion drives new customer engagement really well. For sellers (which is what we care about), it means access to a wider audience and more sales opportunities – and that can only be a good thing. 

How Mirakl Powers Best Buy’s Marketplace

Mirakl’s eCommerce platform is the engine behind Best Buy’s marketplace. It provides:

  • A seamless way for sellers to list products across multiple categories
  • Efficient onboarding through Mirakl Connect
  • Built-in tools for catalog management, fulfillment, and pricing
  • Scalable infrastructure that supports eDesk’s Mirakl integration for customer service

Or, in its own words: “Mirakl enables retailers like Best Buy to quickly scale into new categories without losing control over brand and customer experience.”

Which all sounds startlingly like a window of opportunity for eCommerce sellers. Because it is…

Opportunities for Third-Party Sellers

Joining Best Buy’s marketplace gives sellers access to:

  • A trusted retail brand with millions of loyal customers
  • The ability to sell on Best Buy via Mirakl with minimal setup
  • Integrated omnichannel returns and fulfillment options
  • Increased visibility across new product categories

Sellers can also align this expansion with a multichannel support strategy to manage communications and orders across multiple platforms.

Best Buy’s Expansion and What it Means for Sellers

Best Buy is taking inspiration from Walmart’s (well-publicised, for good reason) marketplace strategy, by focusing on:

  • Curated product assortments
  • Third-party sellers vetted for quality and relevance
  • Category expansion beyond the retailer’s core offering
  • Omnichannel services like buy online, pick up in-store

This approach balances rapid growth with brand trust, to make sure the Best Buy marketplace complements the brand’s retail identity. Clever.
