A Commitments Decision, Not a Verdict
On August 3, 2026, the Authority for Consumers and Markets (ACM) published a draft decision proposing to make legally binding a set of commitments from Bol.com B.V., the Netherlands' dominant online marketplace. The case, filed under number ACM/26/200895, followed an investigation into signals that Bol favored its own product listings and certain sellers, and used data collected from third-party vendors to strengthen its own competitive position. The draft decision is open for public comment through September 13, 2026, after which ACM will issue a final ruling (ACM, Aug 3 2026; ACM case file).
The notable part is what ACM did not find. Dutch outlet Ecommerce News reported that ACM identified risks around Bol's dual role as platform and seller but explicitly stated it had established neither a dominant market position nor a legal violation — "geen machtspositie of overtreding vastgesteld" (Ecommerce News, 2026). Instead of building an antitrust case toward a fine, ACM accepted Bol's voluntary commitments and is now proposing to make them enforceable.
What Bol Actually Promised
The commitments center on the "buy box" — the mechanism that decides which seller's offer for an identical product appears first when a customer searches. Ecommerce News reported ACM found evidence Bol gave its own offers preferential positioning without a performance-based justification; Bol has now committed to determining prominent placement by seller performance metrics rather than ownership. On data, Bol pledged not to use information collected from third-party sellers' listings to advantage its own retail operations, and to give sellers more visibility into customer search behavior in return. On pricing, Bol will present price indications more clearly, in line with ACM's existing guidelines. Bol's own announcement adds that sellers will be able to participate in promotional programs, like "Select Deals," under the same terms as Bol itself, and that complaint-handling and illegal-content reporting will be faster and simpler (Bol.com corporate site, Aug 3 2026).
The Case for Scrutiny, Stated Fairly
The strongest argument for ACM's intervention is structural, not conspiratorial: a marketplace that is simultaneously the referee and a competing player has a built-in conflict of interest. Ecommerce News notes Bol holds a commanding lead over Amazon in Dutch online retail — with thousands of business sellers and millions of consumers routing through a single storefront, there is no meaningfully competitive alternative venue for most Dutch merchants. If Bol's algorithm quietly tilted toward its own listings, or if Bol could see a rival seller's demand data before that seller could react to it, the harm would be diffuse, hard for any individual seller to prove, and exactly the kind of asymmetry that a case-by-case civil dispute struggles to fix. A regulator with subpoena power and cross-market visibility is the more credible venue to surface that pattern than seller litigation ever would be.
Why the Remedy Fits the Finding
But having made that case, the remedy ACM chose is a genuinely good template — better, arguably, than the alternative most people default to. ACM did not need new legislation, a gatekeeper designation, or a blanket EU Digital Markets Act-style ex-ante ban to act; Bol is not a DMA-designated gatekeeper, and this proceeding runs entirely on ordinary Dutch competition-law tools. ACM investigated, found specific practices worth fixing, negotiated concrete behavioral commitments, and is making those specific commitments — not a generic self-preferencing prohibition — legally binding. That is proportionality in practice: the remedy tracks the actual, identified conduct (buy-box weighting, data use, price clarity) rather than imposing a categorical rule on business models ACM never examined. No violation was proven, no fine was levied, and Bol avoided the deterrent-chilling signal a formal infringement finding would send to every other Dutch platform weighing whether to expand into first-party retail alongside third-party hosting. Commitment decisions like this — ACM has used the same tool in sectors from insurance pooling to hospital mergers — let a regulator correct specific harms while preserving the general presumption that vertically integrated marketplaces are lawful.
The Catch Worth Watching
The risk is scope creep dressed as tidiness. Bundling customer-contact findability and illegal-content reporting into a competition-law commitments file blurs antitrust remedy with consumer-protection and content-moderation mandates that arguably belong under the EU's Digital Services Act or Platform-to-Business Regulation, not a competition authority's toezeggingsbesluit. And because the commitments become binding without an underlying violation finding, Bol has effectively accepted an ongoing compliance relationship with ACM in exchange for a clean legal record — a trade other platforms should note before assuming cooperation is costless. The consultation period closing September 13 is the last chance for sellers, rivals, or Bol itself to argue the line was drawn in the wrong place.
