Dutch Regulator Blocks KPN's Fiber Network Takeover to Protect 200,000 Households from Higher Internet Bills
The Hague, Saturday, 13 June 2026.
The ACM has blocked Glaspoort, a KPN-APG joint venture, from acquiring Delta Fiber’s networks, warning that reduced competition could push up internet costs for consumers and businesses across the Netherlands.
A Decision That Reshapes the Dutch Telecom Landscape
On Monday, 8 June 2026, the Dutch Authority for Consumers and Markets (ACM), headquartered in The Hague, announced its decision to block Glaspoort — a joint venture between telecom giant KPN and pension fund APG — from acquiring a portion of the fiber-optic networks belonging to Delta Fiber Nederland (Delta) [3][4]. The blocked deal would have transferred control of a fiber network serving approximately 200,000 households in the Netherlands [3][4]. The ACM’s intervention signals a firm regulatory line: market consolidation that threatens competitive balance will not be permitted, regardless of the scale or financial firepower of the parties involved.
Why the ACM Said No
The core of the ACM’s concern is straightforward: concentration of ownership in critical digital infrastructure reduces the number of genuine competitors, and fewer competitors typically mean higher prices and lower quality for consumers and businesses alike [4]. According to the regulator, KPN already owns ‘by far the most fiber-optic networks’ in the Netherlands, and allowing it to absorb Delta’s networks would have further entrenched that dominant market position [4]. In the affected areas covered by the roughly 200,000 households in question, the acquisition would have left consumers able to choose from only two competing networks: KPN and VodafoneZiggo [4]. Critically, because VodafoneZiggo does not offer network access to third-party telecom providers, operators without their own infrastructure — such as Odido — would have been left entirely dependent on KPN for network access [4]. That level of dependency, the ACM determined, would structurally weaken competition in those regions [3][4].
KPN’s Response and Next Steps
KPN, responding via press agency ANP, stated that it ‘regrets’ the decision and indicated it would study the ruling alongside the other parties involved, while considering possible next steps [4]. Under Dutch regulatory procedure, the companies have the right to appeal if they disagree with the ACM’s assessment [4]. As of Saturday, 13 June 2026, no formal appeal had been publicly announced [alert! ‘No confirmation of appeal filing found in available sources as of publication date’]. The decision was first publicly reported on 8 June 2026, and the ACM made the formal announcement the same day [3][4].
Regulation as a Tool for Innovation, Not Just Control
The Glaspoort-Delta ruling did not stand in isolation. Just days after the blockade was announced, Mickie Schoch — who has served as Director of Telecom, Transport and Post at the ACM since December 2025 — delivered a keynote speech at the Telecompaper Insights Congress, addressing the ACM’s broader role in the digital economy [1]. Schoch made clear that European regulatory instruments are not merely defensive tools designed to restrain dominant players, but active levers for driving innovation. ‘The ACM is responsible for supervising the Digital Services Act (DSA), the Platform-to-Business Act, the Digital Markets Act (DMA), the Data Act, and the Data Governance Act,’ she stated. ‘These are European regulations that ensure a well-functioning digital market and a safe online environment, but with which we also help drive innovation’ [1]. Her remarks reframe regulation as a competitive enabler — the argument being that without consistent rules of engagement, startups and new market entrants cannot compete fairly against entrenched gatekeepers.
From Bell’s First Call to Fiber Monopolies: A 150-Year Warning
Schoch grounded her argument in a historical perspective that stretches back 150 years. In 1876 — exactly one and a half centuries before this speech — Alexander Graham Bell made the first telephone call [1]. Just one year later, in 1877, approximately 3,000 telephone devices had been sold; by 1900, that figure had reached one million [1]. Yet rapid growth brought fragmentation: competing telephone networks were incompatible with one another, and it ultimately required government intervention at the end of the nineteenth century to connect those siloed systems [1]. The lesson Schoch drew is that the telecom sector has a long history of requiring regulatory oversight to prevent monopolistic consolidation from strangling the very innovation it once enabled — a lesson that applies with equal force to today’s fiber-optic and digital platform ecosystems [1].
The European Regulatory Toolkit: DMA, Data Act, and What Comes Next
Several European legislative frameworks are central to the ACM’s supervisory approach in 2026. The Digital Markets Act (DMA) obliges so-called ‘gatekeepers’ — companies such as Apple and Google — to ensure interoperability, giving startups fair access to app stores and data [1]. The Data Act, meanwhile, ensures that users retain control over data generated by smart devices, and requires cloud providers to make switching between platforms free and technically seamless [1]. In 2025, the ACM became the first authority in Europe to publish a ‘Data Sharing Guidelines’ document (‘Leidraad datadelen’), designed to explain the rules to manufacturers and providers of smart devices [1]. Looking ahead to the second half of 2026, the ACM expects to publish a companion document — the ‘Cloud Guidelines’ (‘Leidraad Cloud’) — to oversee compliance with cloud-switching rules and safeguard digital autonomy [1]. On the legislative horizon, the proposed European ‘Digital Networks Act’ (DNA) is set to revise the foundations of Dutch telecommunications law, retaining principles of interoperability, interconnection, and net neutrality while adding new objectives focused on resilience and sustainability [1]. In a direct reflection of these dynamics, KPN and Schwartz Digits recently launched a new European cloud service, partly in response to the Cloud and AI Development Act [1].
A Broader Innovation Ecosystem Under Pressure
The ACM’s intervention in the fiber market arrives in a broader Dutch and European innovation context that is both dynamic and financially significant. Research conducted by Sharp (based in Utrecht), carried out by Markteffect among 509 respondents, found that IT problems cost the Dutch economy more than €3.4 billion in lost productivity annually, with 24 percent of employees losing at least 15 minutes per day to IT-related disruptions — amounting to more than €14.2 million in lost output per day [3]. These figures underscore why resilient, competitive, and well-regulated digital infrastructure is not merely a consumer issue but a macroeconomic one. Separately, the Amsterdam-based sensor technology firm Innoseis Sensor Technologies — a spin-off of Nikhef with ten employees — raised €6 million in an investment round led by Forward.one to scale its MEMS sensor technology internationally; its technology is already being used by Australia’s Fleet Space Technologies for measurements on the moon [3]. Meanwhile, Helsinki-based Skyfora raised €6.5 million from investors including Eviny Ventures, Ugly Duckling Ventures, Lumo Labs, EIC Fund, and Business Finland, to convert existing mobile networks into real-time atmospheric weather sensor networks, with a commercial rollout including a real-time data API and dashboard planned for 2026 [3].
The Stakes of Getting the Balance Right
Schoch’s speech, and the ACM’s decision on the Glaspoort-Delta deal, together articulate a coherent regulatory philosophy: that healthy market competition and active innovation are not opposing goals but mutually dependent outcomes. ‘Healthy market functioning means that the best service wins, not the biggest gatekeeper. That innovation is rewarded, not blocked,’ Schoch said at the Telecompaper Insights Congress [1]. For the roughly 200,000 Dutch households that would have been directly affected by the Glaspoort acquisition, the ACM’s ruling on 8 June 2026 is a concrete expression of that principle [3][4]. For the wider digital economy — from cloud switching rules to smart device data rights — the regulatory frameworks now taking shape across Europe will determine whether the next generation of digital innovators gets a fair shot at competing in a market that, without oversight, has a well-documented tendency to consolidate power in the hands of the few.
