On 8 October 2026 the Bundeskartellamt cleared the acquisition of Carwow's German business by Oak Germany Buyer GmbH, the parent of the mobile.de car marketplace. It is a short, unremarkable decision, and that is what makes it useful. It is a merger-control ruling, not a Section 19a case. The Bundeskartellamt's press release does not mention Section 19a, and this article does not claim otherwise. It does show how Germany's ordinary competition tools handle a platform deal, and that matters for the debate over how much special-purpose digital regulation Germany needs.
What the Bundeskartellamt decided
According to the Bundeskartellamt's press release, mobile.de runs an online platform that mainly connects used-vehicle dealers with private buyers. Carwow runs a marketplace for new vehicles, where customers configure a car across several manufacturer brands and receive matched dealer offers. The overlap between the two is limited. Both mediate vehicle leasing as a secondary service, but specialised leasing platforms dominate that segment.
President Andreas Mundt said mobile.de holds a strong position in used-vehicle intermediation, but that acquiring Carwow does not significantly strengthen it. The authority named AutoScout24 as a significant competitive alternative. It also pointed to the online sales channels that manufacturers and dealers run themselves as a further constraint. The authority said it interviewed platform operators, dealers and manufacturers before deciding. Heise's report describes the same rationale.
The deal was announced on 25 August 2026. Carwow's announcement said financial terms were undisclosed. It also said Carwow.de would keep its brand, team and leadership, and that the two companies would operate standalone until clearance, with no operational integration beforehand. Carwow Group said the sale would let it focus on the UK and Spain.
The strongest case for more scrutiny
There is a serious argument that a clearance like this is too easy. mobile.de is a dominant gateway for used-car listings, and a gateway can leverage its position into adjacent markets. Carwow's configurator-and-dealer-offer model is a new-car lead-generation channel that could one day compete with mobile.de's dealer relationships. Buying it could remove a potential competitor before it grows. Regulators worry about this kind of acquisition of a small adjacent player, and they are right to look for it.
But the decision itself is a response to that argument. The authority looked at whether the buyer's strong position would be strengthened. It found the two businesses largely complementary, found AutoScout24 a credible alternative, and found that manufacturer and dealer channels limit market power. A potential-competition theory needs evidence that Carwow would otherwise have entered used-car intermediation at scale. The public record gives no sign of that. Without such evidence, blocking a deal on speculation would punish the very marketplace entrepreneurship that Germany's platform economy needs.
Why the Section 19a comparison matters
Section 19a of the Competition Act (GWB) works differently. The Bundeskartellamt first designates a company as being of paramount significance for competition across markets, then can prohibit specific practices. Its proceedings page lists five designated groups: Alphabet/Google, Meta, Amazon, Apple and Microsoft. It also records an order against Amazon in February 2026 to disgorge €59 million and restrict price-control mechanisms. The Microsoft designation of 30 September 2024 lasts five years and rests on the breadth of Microsoft's cross-market ecosystem.
mobile.de and Carwow are not on that list, and the mobile.de decision gives no reason to put them there. A marketplace that is strong in one segment, faces a close rival and is constrained by manufacturers' own channels is a normal merger-control problem. Section 19a exists for ecosystem-wide, cross-market power. The risk is that policymakers read every strong platform as a 19a candidate. That would impose designation costs and compliance uncertainty on companies whose power is real but bounded, and it would deter the deals that let smaller platforms exit or consolidate.
What this shows about proportionate enforcement
The decision is an example of proportionate regulation. The authority applied the standard test (does the deal significantly strengthen an existing position?), gathered market evidence, and cleared the deal in a way that gives businesses certainty. The deal was notified on 8 September, according to press coverage, which would make this roughly a one-month review. Predictable timelines matter to founders and investors, because a credible exit through a sale to a larger platform is part of what funds new ventures.
There are two things to watch. First, whether AutoScout24's position stays strong in practice, since the clearance depends on it as a real alternative. If dealers find they have no practical alternative to mobile.de after Carwow is integrated, the authority has other tools: abuse control under the general rules and the market monitoring it already does. Second, whether Carwow's auction product for dealer sourcing stays independent, as the parties have promised. Those are questions for follow-up, not reasons to have blocked the deal.
Takeaway
Germany's competition law is working as intended here. Strong merger control handles a deal between two partly complementary marketplaces, while the heavier Section 19a regime is kept for the few companies whose power cuts across markets. Keeping those two tools separate protects innovation and still lets enforcers act when real harm shows up.
