How Retail Media has Disrupted the eCommerce Flywheel for Marketplaces
The flywheel effect is every business' dream: a self-sustaining cycle where growth feeds more growth, requiring less effort over time.
Perhaps the most famous example of such a strategy is the eCommerce flywheel Jeff Bezos sketched on the back of a napkin and eventually used to turn Amazon into a trillion-dollar company.
In the Amazon flywheel, traffic brings sellers, sellers boost selection and shoppers leave happy. It was the blueprint that forever transformed retail. But here’s the catch: that flywheel looks rusty in today’s retail media-driven world.

Today, offering the best product assortment is vital, but not enough. Customers demand the best online shopping experiences, and brands are ready to pay to stand out from the growing competition. Personalized Retail Media is the missing cog in the old flywheel and what will lead to real business transformation.
To achieve exponential and lasting growth, businesses need dynamic supply through a marketplace, profitable demand by monetizing traffic with retail media, and a high-quality, self-sustaining ecosystem with tools that enable sellers and brands to deliver the scale while enhancing the customer experience. This is the true catalyst for commerce in this era of retail.
Unlike the Amazon flywheel, this new eCommerce flywheel considers the impact a growing marketplace has on the customer experience, combining the power of marketplaces and retail media.

As marketplaces grow and more products flood in, competition for visibility heats up, fueling seller’s retail media investments. But visibility can’t come at the cost of customer experience—the engine of real growth. A high-performing retail media solution strikes the perfect balance, keeping promoted products relevant and personalized while satisfying both sellers and shoppers. In turn, this feeds the flywheel, as more satisfied shoppers means more sales and a higher attractivity for sellers.
It’s no wonder the combination of retail media and marketplaces is recognized as a true recipe for retail transformation. In fact, separate research from Boston Consulting Group and Coresight Research both cite marketplaces and retail media as the top strategies that drive the most sustainable growth and profitability.
The retail media and marketplace flywheel in action
Leaders like Walmart and Amazon haven’t missed out on this gold mine. They display ads on almost 100% of their search queries, fully monetizing their search inventory. What’s impressive is that they’ve done it with various brands — with less than 15% of sponsored impressions coming from major, tier-one brands. What’s more, third-party brands are key drivers of retail media growth for them. They spend 127% more on Sponsored Product Ads and 146% more on Sponsored Videos compared to established brands.
This strategy is paying off, as they are no longer dependent on a small number of big brands that could create diversification challenges and reduce bargaining power. Even better, their advertising revenue is soaring. In 2024, Amazon generated over $50 billion in global advertising revenue (+16% YoY). For Walmart, a third of its revenue is now driven by retail media, with the figures reaching $3.4 billion (+20% YoY).

So what, exactly, are marketplaces like Walmart and Amazon doing differently today?
First and foremost, their retail media solutions are accessible via self-service for their sellers, with campaign performance boosted by AI, making the platforms intuitive and easy to use.
