Competition Law and Future Evolution of Danish and EU Antitrust Governance

1. Introduction

The future of Danish and EU antitrust governance is moving from a traditional model centred primarily on price, output, market shares and conventional cartel behaviour toward a broader governance framework capable of dealing with digital platforms, artificial intelligence, data, algorithms, ecosystems, sustainability, supply-chain resilience, innovation and rapidly changing market structures.

At EU level, the principal legal foundation remains Articles 101 and 102 TFEU, supported by the EU Merger Regulation, Regulation 1/2003, the ECN framework and increasingly the Digital Markets Act (DMA) and Foreign Subsidies Regulation. Articles 101–106 TFEU remain the Treaty foundation of EU competition law.

Denmark operates within this European framework through the Danish Competition and Consumer Authority (Konkurrence- og Forbrugerstyrelsen) and the Danish competition courts/appeal structure. Denmark is part of the European Competition Network, through which national competition authorities cooperate with the European Commission in enforcing EU competition law.

The future therefore involves not the replacement of Danish competition law by EU law, but deeper integration between Danish enforcement, EU antitrust rules, sector regulation and new digital-market legislation.

2. Existing Danish and EU Antitrust Governance

The system can broadly be understood as four interconnected layers:

A. Danish competition law

The Danish framework principally derives from the Danish Competition Act, enforced by Danish competition authorities.

Important functions include:

• prohibition of restrictive agreements;
• prohibition of abuse of dominance;
• merger control;
• investigations and dawn raids;
• commitments and remedies;
• cooperation with the European Commission;
• enforcement against cartels and bid-rigging;
• economic analysis of relevant markets.

B. EU competition law

The principal substantive provisions are:

• Article 101 TFEU — restrictive agreements, decisions and concerted practices;
• Article 102 TFEU — abuse of dominant position;
• Article 106 TFEU — public undertakings and undertakings with special or exclusive rights;
• EU Merger Regulation;
• State-aid rules under Articles 107–109 TFEU.

C. European Competition Network

Regulation 1/2003 created the decentralised enforcement system under which national competition authorities and the Commission apply EU competition rules.

The ECN+ Directive subsequently strengthened national competition authorities by providing minimum guarantees concerning independence, enforcement powers and interim measures.

D. New digital-market governance

The DMA introduces an important change: some digital conduct can be prohibited without the Commission having to establish dominance and conduct the traditional Article 102 analysis in every individual case.

The Commission has already designated major gatekeepers and, by 2026, the DMA framework covers services of Alphabet, Amazon, Apple, Booking, ByteDance, Meta and Microsoft.

3. Why the Traditional Antitrust Model Is Evolving

Future Danish and EU competition governance must address markets where:

1. price is zero;
2. consumers pay with data;
3. algorithms determine prices;
4. platforms control access to customers;
5. network effects create rapid concentration;
6. ecosystems span several adjacent markets;
7. AI can change competitive conditions extremely quickly;
8. innovation rather than current price is the principal competitive variable;
9. cloud infrastructure becomes an essential commercial input;
10. acquisitions may eliminate future competitors before they become substantial competitors.

This means that conventional indicators such as market share and current prices may increasingly have to be supplemented by:

• switching costs;
• data advantages;
• interoperability;
• access to APIs;
• ecosystem dependence;
• multi-homing;
• network effects;
• algorithmic coordination;
• innovation pipelines;
• access to computing capacity;
• control of standards;
• control over distribution channels.

4. Case Law and Its Importance for Future Governance

Case 1 — United Brands v Commission, Case 27/76

Principle

United Brands remains one of the foundational EU dominance cases.

The Court examined:

• market definition;
• dominance;
• economic power;
• barriers to entry;
• customer dependence;
• abusive conduct.

Future significance

Its importance for future Danish/EU governance is that dominance is not simply determined by market share.

In digital and AI markets, authorities may therefore need to examine:

• technological advantages;
• user networks;
• data accumulation;
• ecosystem lock-in;
• switching costs;
• infrastructure control.

The case provides a conceptual foundation for moving from a purely numerical market-share approach toward a structural assessment of economic power.

5. Case 2 — Hoffmann-La Roche v Commission, Case 85/76

Principle

The Court established the importance of loyalty-inducing arrangements and exclusionary conduct by dominant undertakings.

The case is particularly important for understanding how a dominant undertaking can use commercial arrangements to restrict effective competition even where the conduct does not resemble a conventional cartel.

Future relevance

The principle becomes increasingly significant in:

• platform exclusivity;
• digital ecosystems;
• cloud contracts;
• software ecosystems;
• app-store arrangements;
• loyalty mechanisms;
• algorithmically personalised incentives.

Future governance may therefore scrutinise not merely explicit exclusivity clauses but also technical or economic mechanisms producing equivalent exclusionary effects.

6. Case 3 — Bronner v Mediaprint, Case C-7/97

Principle

Bronner is one of the principal EU cases concerning the essential facilities/refusal-to-deal doctrine.

The Court imposed demanding conditions before requiring a dominant undertaking to provide access to infrastructure controlled by it.

Future Danish and EU significance

This doctrine has major implications for:

• cloud computing;
• payment infrastructure;
• digital identity systems;
• data access;
• API infrastructure;
• telecommunications networks;
• energy infrastructure;
• AI computing infrastructure.

The future question may increasingly become:

When does control over a technologically indispensable infrastructure justify mandatory access?

This will be particularly important where infrastructure ownership creates substantial barriers to entry.

7. Case 4 — Google Shopping, Case AT.39740 / General Court

The Google Shopping litigation represents the transition of EU antitrust governance into the platform economy.

The Commission found that Google had favoured its own comparison-shopping service in its search results.

Importance

The case illustrates the growing relevance of:

• self-preferencing;
• ranking;
• platform neutrality;
• vertical integration;
• algorithmic visibility;
• control over access to consumers.

Future significance

The concept of self-preferencing has moved beyond conventional Article 102 enforcement and is now directly addressed by the DMA's digital-market framework.

Indeed, the Commission's 2026 enforcement against Google under the DMA concerned, among other matters, preferential treatment of Google's own services in Google Search.

This illustrates an important evolutionary shift:

Ex-post antitrust → ex-ante digital regulation.

8. Case 5 — Intel v Commission, Case C-413/14 P

Principle

The Intel litigation significantly influenced the treatment of exclusionary rebates under Article 102 TFEU.

The Court required greater attention to the economic circumstances surrounding potentially exclusionary rebate practices, particularly where an undertaking disputes the capability of its conduct to foreclose equally efficient competitors.

Future significance

This approach is important for future algorithmic and AI-driven markets because authorities increasingly need to distinguish:

• aggressive competition;
• efficiency-enhancing conduct;
• exclusionary conduct.

Algorithms may generate extremely sophisticated:

• discounts;
• personalised pricing;
• loyalty incentives;
• rebates;
• bundling strategies.

Future antitrust governance therefore needs economic evidence combined with technical evidence.

9. Case 6 — Towercast, Case C-449/21

Principle

Towercast is particularly important for future merger governance.

The Court held that a concentration falling below the thresholds of the EU Merger Regulation and national merger-control thresholds can, in appropriate circumstances, still be examined under Article 102 TFEU.

Future significance

This is highly relevant to acquisitions of:

• start-ups;
• AI companies;
• fintech companies;
• biotech innovators;
• digital platforms;
• data-driven businesses.

A small company may have a relatively small turnover but possess:

• critical technology;
• valuable data;
• innovative algorithms;
• a promising AI model;
• an important user community;
• strategically significant intellectual property.

Consequently, future merger governance may increasingly focus on competitive potential rather than only current turnover.

10. Case 7 — Illumina/Grail

The Illumina/Grail controversy illustrates the changing boundaries of EU merger jurisdiction and the importance of innovation competition.

The transaction involved a major established biotechnology company and a developing cancer-detection business.

The controversy helped expose the tension between:

• formal merger thresholds;
• potential competition;
• innovation;
• strategic technologies;
• nascent competitors.

Future relevance

The lesson for Denmark and the EU is particularly important for:

• AI;
• biotechnology;
• quantum computing;
• clean technology;
• hydrogen;
• advanced semiconductors;
• digital infrastructure.

Competition authorities increasingly need to ask:

What competitive force might disappear tomorrow even if it appears small today?

11. Case 8 — Post Danmark I, Case C-209/10

This case is particularly relevant from a Danish perspective.

The litigation concerned the Danish postal market and Article 102 TFEU.

Importance

Post Danmark demonstrates the interaction between:

• national markets;
• public-service obligations;
• dominant undertakings;
• pricing practices;
• EU competition law.

Future significance

Denmark will increasingly face similar issues in:

• energy;
• telecommunications;
• postal and logistics networks;
• public transport;
• digital public infrastructure;
• healthcare infrastructure.

Future competition governance therefore has to reconcile competition with legitimate public-service objectives.

12. Case 9 — Post Danmark II, Case C-23/14

Post Danmark II further developed the treatment of rebate systems by dominant undertakings.

It demonstrates that EU competition law can scrutinise pricing mechanisms not simply because they produce low prices, but because their structure and economic effects may exclude competitors.

Future relevance

The principle becomes especially important where pricing is automated.

For example, an AI-driven platform could continuously adjust:

• discounts;
• commissions;
• rebates;
• advertising prices;
• delivery fees.

Future enforcement may therefore have to reconstruct algorithmic pricing histories rather than examining a few published prices.

13. Future Governance of Digital Platforms

The EU's Digital Markets Act represents perhaps the clearest example of future competition governance.

The traditional model asks:

Is the undertaking dominant, and is the conduct abusive?

The DMA often asks:

Has a designated gatekeeper engaged in conduct specifically prohibited by the regulatory framework?

This creates a parallel system:

The Commission's experience already demonstrates this evolution: Apple and Meta were found in breach of DMA obligations in 2025, while Google faced further DMA enforcement in 2026.

14. AI and Algorithmic Competition

AI will probably become one of the most important future areas of Danish and EU antitrust governance.

Potential concerns include:

A. Algorithmic collusion

Competitors may use automated pricing systems capable of responding rapidly to each other's prices.

B. AI-assisted coordination

Algorithms could make tacit coordination easier by:

• monitoring competitors;
• predicting reactions;
• adjusting prices automatically.

C. AI infrastructure concentration

Competition concerns may arise where a small number of firms control:

• GPUs;
• cloud computing;
• foundation models;
• training datasets;
• AI distribution channels.

D. Vertical integration

An infrastructure provider could potentially favour its own AI applications over rival applications.

E. Data advantages

Large datasets can reinforce network effects and create barriers to entry.

15. Cloud Computing as the Next Antitrust Frontier

Cloud markets demonstrate how competition law is increasingly concerned with infrastructure rather than merely consumer products.

The Commission has been examining cloud computing under the DMA, including interoperability, financial conditions and contractual terms.

In June 2026, the Commission announced preliminary views that Amazon Web Services and Microsoft Azure should be designated as DMA gatekeeper services, citing factors including entrenched positions, switching costs and ecosystem effects.

This indicates a possible future governance model where infrastructure access becomes a central competition issue.

16. Future Merger Control

The EU is currently undergoing a major review of its merger framework.

The Commission published draft new Merger Guidelines in April 2026 after a broad review intended to address transformations including:

• digitalisation;
• globalisation;
• decarbonisation;
• innovation;
• changing market structures. 

The future assessment of mergers may therefore increasingly consider:

Traditional factors

• market shares;
• concentration;
• unilateral effects;
• coordinated effects;
• efficiencies.

Newer factors

• innovation pipelines;
• nascent competitors;
• data;
• ecosystems;
• network effects;
• dynamic competition;
• resilience;
• technological dependencies.

17. Sustainability and Competition Law

Climate policy is another major area of evolution.

Future Danish and EU authorities must balance competition with:

• decarbonisation;
• green investment;
• energy transition;
• circular economy initiatives;
• renewable-energy infrastructure;
• sustainable transport.

The Commission has expressly identified decarbonisation, resilience and investment as increasingly important dimensions of its competition-policy agenda.

However, environmental objectives cannot automatically justify otherwise restrictive conduct. Authorities must examine whether cooperation is:

• genuinely necessary;
• proportionate;
• sufficiently beneficial;
• compatible with competition rules.

18. Danish Competition Governance: Future Direction

Denmark is likely to experience these developments through several channels.

18.1 Greater EU–Danish cooperation

Danish enforcement will increasingly interact with:

• European Commission investigations;
• ECN cooperation;
• DMA enforcement;
• EU merger control;
• cross-border digital investigations.

18.2 Greater use of economic evidence

Authorities will increasingly employ:

• econometrics;
• pricing datasets;
• consumer-switching data;
• network-effect analysis;
• simulations;
• merger modelling.

18.3 Greater technological expertise

Competition authorities will need specialists in:

• AI;
• algorithms;
• cybersecurity;
• cloud computing;
• data science;
• digital forensics.

18.4 Faster interim intervention

Rapid digital markets can change before a conventional investigation concludes.

Consequently, interim measures may become increasingly important. The ECN+ framework already provides national authorities with interim-measure powers.

19. Procedural Evolution

A significant future issue is whether traditional competition procedures are sufficiently fast for modern markets.

The Commission has been reviewing the procedural framework of Regulation 1/2003 and Regulation 773/2004, recognising that rules designed more than two decades ago face challenges from digitalisation and modern enforcement.

Future procedures may therefore involve:

• faster investigations;
• automated evidence processing;
• algorithmic document review;
• real-time monitoring;
• stronger interim measures;
• improved cross-border cooperation;
• more technical investigations.

20. Evidence and Digital Forensics

The future competition investigation will increasingly involve evidence such as:

• source code;
• algorithmic instructions;
• APIs;
• cloud logs;
• transaction databases;
• internal messaging;
• AI-training records;
• pricing algorithms;
• digital communications;
• platform-ranking data.

This changes the nature of competition litigation.

A future Danish competition case may require the authority and courts to understand not only what a company did, but also:

How the technological system produced the conduct.

21. The Future Concept of Market Power

The traditional concept:

Market share → dominance → abuse

is gradually being supplemented by:

Data + network effects + switching costs + ecosystem control + infrastructure + innovation + interoperability → structural market power.

This is especially important because a firm may possess considerable competitive power even where its market share appears relatively modest.

22. Competition Governance of Ecosystems

Future antitrust law may increasingly analyse ecosystems rather than isolated markets.

For example:

Operating system → app store → payments → advertising → cloud → AI assistant → data

can create interconnected competitive advantages.

A narrow market-by-market approach may fail to capture how power is transferred between ecosystem layers.

The DMA already reflects this broader structural approach by imposing obligations on designated gatekeepers across multiple core platform services.

23. Denmark as an EU Competition-Law Laboratory

Denmark's relatively advanced digital economy, strong institutions and integration into the EU internal market make Danish enforcement particularly relevant to European competition governance.

Potential future areas include:

• digital banking;
• energy systems;
• offshore wind;
• pharmaceuticals;
• food retail;
• logistics;
• telecommunications;
• AI;
• cloud computing;
• digital advertising;
• platform marketplaces;
• green technology.

Danish competition enforcement can therefore contribute to broader EU interpretation while EU law simultaneously shapes Danish enforcement.

24. Major Future Challenges

1. Speed versus procedural fairness

Fast markets require fast intervention, but undertakings must retain due-process protections.

2. Innovation versus precaution

Authorities must avoid allowing potentially harmful concentration while also avoiding unnecessary interference with innovation.

3. National enforcement versus EU centralisation

Danish authorities will continue to have an important role, but increasingly complex cross-border markets favour coordinated EU enforcement.

4. Antitrust versus sector regulation

Competition authorities will increasingly interact with:

• data regulators;
• telecommunications regulators;
• financial regulators;
• energy regulators;
• AI regulators.

5. Ex-post versus ex-ante regulation

The DMA represents an important movement toward ex-ante regulation, but traditional Articles 101 and 102 remain essential.

6. Sustainability versus competition

Authorities must determine when environmental cooperation produces legitimate benefits and when sustainability claims are used to shield restrictive conduct.

25. Future Model of Danish and EU Antitrust Governance

The emerging structure can be represented as:

Traditional Competition Law
↓
Articles 101 & 102 TFEU
↓
EU Merger Control + Danish Merger Control
↓
ECN / ECN+ Cooperation
↓
Digital Markets Act
↓
Data + AI + Algorithms + Cloud
↓
Ecosystem and Infrastructure Analysis
↓
Dynamic Innovation Analysis
↓
Sustainability + Resilience + Strategic Technology
↓
Integrated European Competition Governance

26. Conclusion

The future evolution of Danish and EU antitrust governance is likely to be characterised by greater technological sophistication, stronger cooperation, more ex-ante regulation and a broader understanding of market power.

The traditional principles of Articles 101 and 102 TFEU will remain fundamental. However, cases such as United Brands, Hoffmann-La Roche, Bronner, Intel, Google Shopping, Post Danmark and Towercast, together with developments surrounding Illumina/Grail, show how competition law has progressively adapted to new forms of economic power.

The next phase is likely to focus particularly on:

• AI and algorithmic competition;
• digital ecosystems;
• cloud infrastructure;
• data and interoperability;
• nascent-competitor acquisitions;
• innovation competition;
• sustainability;
• economic resilience;
• cross-border enforcement;
• ex-ante digital regulation.

The most important institutional development is therefore not simply stricter antitrust enforcement. It is the emergence of a multi-layered competition-governance system, in which Danish authorities, the European Commission, national courts, EU courts and specialised digital regulation operate together.

For Denmark, the future is consequently likely to involve continued national enforcement combined with increasingly integrated EU-level governance, particularly where markets are digital, cross-border, infrastructure-dependent or technologically complex.
