Marketplaces are neither dead nor saturated: they have changed in nature. The channel is still profitable, but it no longer forgives improvisation. Here is where things actually stand, and what it takes to succeed.
A channel you cannot ignore, but a mature one
In 2026 marketplaces are no longer an opportunistic add-on but a structural channel. Amazon, Cdiscount, Fnac-Darty, ManoMano and specialists such as Leroy Merlin and Decathlon have reshaped how people buy.
These platforms hold a large, qualified audience already in a buying frame of mind. Being there means immediate access to traffic that is hard to buy elsewhere, particularly as advertising costs keep climbing.
That maturity brings new constraints. Requirements have tightened on product quality, logistics, customer service and regulatory compliance. Listing a product is no longer enough to sell it: performance depends on careful account management, an understanding of the ranking algorithms and continuous listing work.
The question is no longer whether to sell on a marketplace, but how to sell there effectively and keep doing so.
More competition, but the opportunity has moved
The objection raised most often is competition. It is fair: some categories on the general platforms are saturated. Thousands of sellers offer near-identical products, which drags on prices and margins.
That truth hides another: the opportunity has not gone, it has moved. Platforms have built more specialised categories, brand spaces and areas for higher-value ranges. Sector-specific marketplaces keep appearing and growing.
For a seller that means dropping the generic approach in favour of precise positioning. Three checks become prerequisites:
- identify the growing categories rather than the most visible ones;
- measure the depth of the existing offer before committing;
- understand the real expectations of the buyers on the platform you are targeting.
Marketplaces still pay for those who can read the data properly and build an offer that stands apart.
Profitability and costs: a balance to hold
Selling on a marketplace in 2026 means absorbing several costs: commission, fulfilment, on-platform advertising, returns and sometimes storage. Without a firm strategy these erode profitability quickly.
In exchange, marketplaces offer something rare: predictable volume and the ability to scale fast.
The key sits in the day-to-day management of the account:
- listing optimisation lifts conversion without increasing ad spend;
- close analysis of campaigns concentrates budget on the products that actually perform;
- stock management prevents both stockouts and needless storage costs.
Check this first
A product that sells well can still destroy margin. Recalculate net margin per SKU, commission and fulfilment included, before pushing harder on it.

Beyond direct sales, marketplaces build brand awareness. Shoppers increasingly use them as a product search engine, sometimes before Google. Ranking well with strong listings and good reviews strengthens a brand's credibility.
For emerging brands and direct-to-consumer labels, a marketplace becomes a strategic touchpoint: a place to test an offer, gather feedback quickly and adjust positioning.
That exposure demands tight control of the brand: consistent imagery, quality content, review management and respect for each platform's rules. Marketplaces are no longer only sales channels, they are shop windows.
Automation, AI and new rules
2026 brings faster adoption of AI and automation: automatic bid optimisation, dynamic pricing recommendations, seller scoring. The rules move quickly, and sellers who rely on manual methods alone fall behind.
These tools do not replace expertise. They need interpretation and regular adjustment: a badly configured automatic bidding rule cuts margin or visibility within days. AI helps, provided someone is steering it.
Should you still start, or stay, in 2026?
Yes, but marketplaces do not suit every seller unchanged. They demand more rigour, more strategy and more skill than before. For beginners and established brands alike, success comes from a long view and professional account management.
Outsourcing all or part of the management saves time, avoids expensive mistakes and protects profitability, without hiring a dedicated specialist.
Conclusion
Marketplaces are neither dead nor saturated: they have evolved. They remain a powerful lever for growth, visibility and commercial structure, provided they are approached methodically. For sellers ready to professionalise, the opportunity is real.
