Competition Law and Competition Implications of Governance Concentration

1. Introduction

Governance concentration refers to a situation in which control over the rules, standards, infrastructure, data, access conditions, decision-making mechanisms, or institutional architecture of a market becomes concentrated in one undertaking, a small group of undertakings, or a closely controlled public-private structure.

Traditional competition law focuses primarily on market concentration—for example, whether one undertaking has a large market share. Governance concentration is broader. An undertaking may possess substantial competitive power because it controls the rules by which other competitors must operate, even where it does not technically control the entire downstream market.

This issue has become particularly important in:

• digital platforms and ecosystems;
• app stores and operating systems;
• cloud computing;
• payment systems;
• telecommunications;
• data-sharing infrastructures;
• standards and interoperability frameworks;
• energy and transport infrastructure;
• public procurement platforms;
• financial-market infrastructure;
• AI ecosystems; and
• markets involving dominant State-owned or publicly supported enterprises.

The European Commission's current digital-market framework illustrates this development: the Digital Markets Act identifies certain large platforms as gatekeepers and imposes obligations concerning interoperability, data portability, self-preferencing and access.

2. Meaning of Governance Concentration

Governance concentration can arise when an undertaking controls one or more of the following:

A. Access rules

The undertaking determines who can enter or participate in an ecosystem.

Examples:

• app-store admission;
• cloud-platform access;
• payment-network participation;
• access to an essential database;
• access to technical infrastructure.

B. Technical standards

A firm may control standards that determine whether rival products can interoperate.

C. Data governance

Control over commercially valuable data can allow an undertaking to influence competitors' ability to enter or expand.

D. Ranking and recommendation systems

Digital platforms may determine:

• which sellers appear first;
• which products receive visibility;
• which applications are promoted;
• which advertisements receive exposure.

E. Dispute-resolution and enforcement mechanisms

A platform may establish the rules for resolving disputes between itself, suppliers and competitors.

F. Ecosystem governance

The most significant form occurs where a company simultaneously controls:

infrastructure + data + standards + access + distribution + customer relationships.

This can produce a form of structural market power even where conventional market-share analysis does not fully capture the competitive problem.

3. Governance Concentration vs Market Concentration

Therefore, high market share is not necessary for governance power, and governance control can reinforce an existing dominant position.

4. Competition-Law Framework

Governance concentration can implicate several areas of competition law.

A. Abuse of dominance

Where a dominant undertaking controls a critical governance layer, the following conduct may become problematic:

• discriminatory access;
• refusal to deal;
• exclusionary interoperability restrictions;
• self-preferencing;
• tying and bundling;
• discriminatory ranking;
• excessive switching costs;
• exploitative data practices;
• discriminatory technical standards.

B. Essential-facility principles

Where competitors cannot realistically compete without access to infrastructure or a particular system, refusal or discriminatory restriction of access may raise essential-facility concerns.

C. Vertical foreclosure

A vertically integrated governance operator may favour its downstream business over independent competitors.

D. Merger control

A merger can increase governance concentration even where traditional market-share increases appear modest.

For example:

Platform A + data provider B + infrastructure provider C

may produce substantial control over the competitive architecture of an ecosystem.

E. State aid and competitive neutrality

Where governance infrastructure is controlled or supported by the State, competition concerns can arise if selective governmental support gives an undertaking an advantage unavailable to rivals. EU State-aid rules, for example, examine whether State intervention confers a selective economic advantage that distorts competition.

5. Key Competition Implications

5.1 Exclusion of Competitors

Governance concentration can enable a firm to establish rules that make competing products technically or commercially difficult to use.

The concern is particularly strong where the governance operator is also a downstream competitor.

For example:

Platform owner → controls access → owns competing service → controls ranking → competes against users

This creates an inherent risk of vertical foreclosure.

6. Self-Preferencing

Self-preferencing occurs when a platform gives its own products or services preferential treatment over competing products.

The competitive concern is not simply that the platform owns a competing product. It is that the platform controls the decision-making mechanism through which competitors reach consumers.

The EU's contemporary DMA framework specifically addresses this problem. In July 2026, the European Commission found Google non-compliant with the DMA in relation to preferential treatment of its own services in Google Search and imposed a €460 million fine for that aspect of the case.

7. Interoperability and Access

Governance concentration can also produce competition problems where a dominant undertaking controls interoperability.

Suppose:

Operating system → controls APIs → controls device functions → competing applications depend on those functions.

The platform can potentially disadvantage competitors by:

• withholding APIs;
• delaying technical access;
• providing inferior functionality;
• imposing discriminatory conditions;
• limiting data portability.

The DMA expressly addresses interoperability and data portability in mobile ecosystems.

In July 2026, the European Commission also issued binding specification measures concerning Google's Android interoperability and access by competing AI services to certain Android functionality.

8. Data Concentration

Governance concentration frequently produces data concentration.

A dominant platform can simultaneously control:

1. transaction data;
2. user behaviour;
3. search data;
4. seller information;
5. advertising data;
6. performance data.

This creates feedback effects:

More users → more data → better service → more users → greater data advantage.

Competitors may therefore face a barrier to entry even where the underlying technology is replicable.

9. Network Effects

Governance concentration becomes particularly significant in network markets.

A platform becomes more valuable as more users join.

This can produce:

Network effects → user concentration → data concentration → ecosystem expansion → stronger governance power → higher entry barriers.

The resulting competitive problem is not merely the size of the firm but its ability to control the ecosystem's rules.

10. Lock-In and Switching Costs

Governance concentration can make consumers and businesses dependent on a particular ecosystem.

Examples include:

• proprietary data formats;
• non-portable data;
• contractual restrictions;
• technical incompatibility;
• loyalty mechanisms;
• ecosystem-specific applications;
• high migration costs.

The EU's current assessment of cloud markets specifically identifies entrenched positions, lock-in effects and high switching costs as relevant competitive characteristics.

11. Governance Concentration and Artificial Intelligence

AI creates a new dimension.

A small number of firms may control:

• foundation models;
• cloud computing;
• AI chips;
• training data;
• application marketplaces;
• APIs;
• distribution channels.

This can create multi-layer governance concentration.

For example:

Cloud infrastructure
↓
Foundation model
↓
API
↓
Application marketplace
↓
End users

If the same economic group controls several layers, it may have the ability to disadvantage competing AI developers at multiple stages.

The EU's current digital-market work expressly identifies cloud and AI as important areas for ensuring contestability.

12. Important Case Laws

1. United States v. Microsoft Corp. (2001)

Jurisdiction: United States
Issue: Operating-system dominance and browser distribution.

Microsoft used its control over the Windows operating-system ecosystem in ways that the courts found unlawfully maintained its monopoly and restricted competition.

Relevance to governance concentration

The case demonstrates that control over a platform layer can confer power over adjacent markets.

The operating system was not merely a product; it was an important governance layer through which competing software reached consumers.

Principle

Control over an essential technological ecosystem can become a source of exclusionary market power when used to restrict competitive alternatives.

2. European Commission v. Microsoft / Microsoft (Windows Media Player)

Case: Commission Decision 2004/2007, Microsoft

The Commission addressed Microsoft's tying of Windows with Windows Media Player and its refusal to provide interoperability information.

Governance significance

Microsoft's control over the operating-system environment allowed it to influence the competitive conditions faced by rival software providers.

The interoperability component is especially important for governance concentration because it demonstrates how technical information can become a competitive resource.

Principle

A dominant undertaking controlling an important technological interface may have competition-law obligations concerning interoperability where its conduct restricts competition.

3. Google Shopping

Case: Google Search (Shopping), European Commission Decision AT.39740 (2017); General Court, Case T-612/17.

The Commission found that Google systematically gave prominent placement to its own comparison-shopping service while according competing comparison-shopping services less favourable treatment.

The General Court substantially upheld the Commission's decision, subject to adjustments concerning certain aspects of the reasoning.

Governance-concentration significance

Google controlled the search-ranking mechanism through which consumers discovered competing services.

Thus, governance power arose from control over:

search infrastructure + ranking + consumer access.

Principle

Control over a digital gateway can create competition concerns when the operator uses that governance position to advantage its own downstream service.

4. Google Android

Case: Commission Decision AT.40099, Google Android (2018); General Court, Case T-604/18.

The case concerned several contractual practices involving Android, including tying and restrictions affecting alternative search and browser services.

Governance significance

Google's position involved several interconnected layers:

• Android operating system;
• Google Play;
• search;
• browsers;
• mobile-device distribution.

The case illustrates how ecosystem governance can reinforce market power across related markets.

Principle

Competition analysis may need to examine the interaction between several ecosystem components rather than treating each product as completely independent.

5. Apple – App Store / Epic Games litigation

Case: Epic Games, Inc. v. Apple Inc.

The dispute concerned Apple's control over distribution of applications through the App Store and the associated payment rules.

Governance significance

Apple controlled:

• access to iOS users;
• app distribution;
• payment mechanisms;
• technical rules;
• contractual conditions.

This makes the case highly relevant to governance concentration.

The fundamental competition question is:

When a platform controls access to consumers and simultaneously competes with businesses dependent upon that platform, how should competition law address the platform's rule-making power?

6. Qualcomm v. Apple / Qualcomm antitrust litigation

Qualcomm-related competition litigation illustrates the importance of control over technological standards, licensing arrangements and critical communications technologies.

Governance significance

Standard-essential technologies can create a form of governance power because manufacturers depend on access to technically necessary intellectual property.

Competition-law concerns can therefore involve:

• licensing conditions;
• access;
• royalties;
• discrimination;
• interoperability.

Principle

Control over technological infrastructure can create market power extending beyond ordinary product-market concentration.

7. Bronner v. Mediaprint

Case: Oscar Bronner GmbH & Co. KG v. Mediaprint, Case C-7/97.

The case concerned access to a newspaper home-delivery system.

The Court of Justice applied strict criteria before requiring a dominant undertaking to provide access to an infrastructure.

Governance significance

It is an important authority for understanding when control over infrastructure can translate into competition-law obligations.

Principle

Not every commercially valuable infrastructure constitutes an essential facility. Mandatory access generally requires stringent conditions.

8. Slovak Telekom

Cases: Slovak Telekom a.s. v Commission, Joined Cases C-165/19 P and C-166/19 P.

The litigation concerned access to telecommunications infrastructure and exclusionary conduct.

Governance significance

Telecommunications infrastructure represents a classic example of governance concentration:

network owner → access conditions → downstream competitors.

Principle

A dominant infrastructure operator may face competition-law scrutiny where its access conditions restrict downstream competition.

13. Chinese Perspective

China's competition framework is also relevant to governance concentration, particularly in digital-platform markets.

The Anti-Monopoly Law of the People's Republic of China, together with the platform-economy enforcement framework, permits examination of conduct involving:

• platform rules;
• discriminatory treatment;
• exclusive arrangements;
• tying;
• algorithmic practices;
• data advantages;
• market dominance.

The Chinese experience is particularly significant because digital platforms may exercise considerable control over merchants and consumers simultaneously.

The Tencent litigation is instructive in the context of tying. Academic comparative analysis notes that China's Supreme People's Court reached a different conclusion from the EU's Android enforcement regarding the competitive effects of platform tying.

This demonstrates an important point: similar governance structures can produce different legal outcomes depending on the evidence concerning market definition, dominance, foreclosure and consumer effects.

14. Governance Concentration and Merger Control

Traditional merger analysis asks:

Will the transaction substantially lessen competition?

Governance concentration adds another question:

Will the transaction give one undertaking control over a strategically important layer of the competitive ecosystem?

For example:

Transaction A

Cloud provider + AI developer

Transaction B

Operating system + identity provider

Transaction C

Payment platform + marketplace

Transaction D

Search engine + advertising exchange

Even where horizontal overlap is limited, the transaction could increase ecosystem control.

Relevant theories include:

• vertical foreclosure;
• conglomerate effects;
• input foreclosure;
• customer foreclosure;
• data accumulation;
• interoperability foreclosure;
• increased switching costs.

15. Governance Concentration and Essential Facilities

The essential-facility doctrine is particularly relevant.

A governance infrastructure may become competitively significant when:

1. competitors require access to it;
2. duplication is impractical;
3. access is objectively necessary;
4. refusal can eliminate effective competition; and
5. access can technically and economically be provided.

However, dominance alone does not automatically create a duty to deal. The stringent approach in Bronner remains important.

16. Governance Concentration and Public Infrastructure

Governance concentration is not restricted to private digital platforms.

It can occur in:

• electricity grids;
• railway infrastructure;
• ports;
• airports;
• telecommunications;
• payment systems;
• public procurement platforms;
• financial clearing systems.

Where the State owns or regulates the infrastructure, competition law may intersect with:

• sector regulation;
• public procurement;
• State-aid law;
• competitive neutrality;
• access regulation.

EU State-aid principles illustrate the concern: selective State intervention can confer an economic advantage on particular undertakings and distort competition.

17. Competitive Neutrality

Governance concentration becomes particularly important where a government-controlled enterprise competes with private undertakings.

Potential advantages may include:

• preferential financing;
• regulatory advantages;
• privileged infrastructure access;
• government guarantees;
• exclusive information;
• preferential procurement.

The competition-law objective is not necessarily to prevent public ownership but to ensure that public control does not unnecessarily distort competitive conditions.

18. Governance Concentration and Algorithms

Modern governance increasingly occurs through algorithms.

A platform can effectively establish market rules through:

• ranking algorithms;
• recommendation systems;
• automated pricing;
• seller allocation;
• advertising auctions;
• fraud detection;
• access decisions.

Therefore, algorithmic governance can become a competition issue where the algorithm systematically disadvantages rivals.

The important legal question is:

Who controls the algorithm that determines the competitive conditions of the market?

19. Remedies

Competition authorities have several potential remedies.

Structural remedies

• divestiture;
• separation of business units;
• ownership restrictions.

Behavioural remedies

• non-discrimination obligations;
• access obligations;
• interoperability;
• data portability;
• transparent ranking;
• prohibition of self-preferencing.

Regulatory remedies

• gatekeeper obligations;
• access regulation;
• technical standards;
• auditing;
• algorithmic transparency.

Merger remedies

• divestiture;
• licensing;
• interoperability commitments;
• data-access commitments;
• firewall obligations.

The appropriate remedy depends on whether the problem is primarily structural, behavioural, technological or institutional.

20. Emerging Governance-Concentration Risks

Future competition-law enforcement is likely to encounter governance concentration in:

1. AI ecosystems

Control over models, compute, data and distribution.

2. Cloud infrastructure

High switching costs and ecosystem lock-in.

3. Digital identity

Control over authentication and user access.

4. Digital payments

Control over payment rails and merchant access.

5. Smart grids

Control over energy-management standards and data.

6. Autonomous mobility

Control over mapping, charging, data and operating platforms.

7. Internet-of-Things ecosystems

Control over interoperability standards.

8. Digital advertising

Control over publisher, advertiser and auction infrastructure.

The EU's 2026 policy work is already examining cloud governance and interoperability, including AWS and Azure's potential treatment as DMA gatekeepers despite not meeting the ordinary quantitative thresholds.

21. Key Legal Tests

A competition authority examining governance concentration should ask:

1. Who controls the infrastructure?
2. Who establishes the rules?
3. Who controls access?
4. Who controls the relevant data?
5. Can competitors realistically switch to another system?
6. Can the infrastructure be replicated?
7. Does the controller compete downstream?
8. Does it favour its own services?
9. Does it discriminate among users?
10. Does the structure create network effects or lock-in?
11. Could the conduct foreclose equally efficient competitors?
12. Are there legitimate efficiency or security justifications?

22. Overall Legal Significance

Governance concentration represents an evolution from the traditional conception of market power.

Traditional analysis asks:

Who sells the product?

Governance analysis increasingly asks:

Who controls the system within which products are sold?

That distinction is especially important in digital and infrastructure markets.

A company may exercise competitive power not merely because it sells a large quantity of goods or services, but because it controls:

the gateway + rules + data + standards + interoperability + distribution.

The contemporary regulatory response reflects this development. The EU's DMA, for example, currently identifies major platform operators across search, operating systems, app stores, marketplaces, advertising, social networks and other core platform services, while its current enforcement agenda includes interoperability, self-preferencing, data access and cloud services.

23. Conclusion

Governance concentration is a significant competition-law concern because control over market architecture can create power that is not adequately captured by conventional market-share analysis.

The principal competition risks are:

• exclusion of competitors;
• discriminatory access;
• self-preferencing;
• interoperability restrictions;
• data concentration;
• network effects;
• ecosystem lock-in;
• vertical foreclosure;
• technological dependency;
• strategic control of standards; and
• reinforcement of dominance through mergers or State support.

The principal case-law lessons from Microsoft, Google Shopping, Google Android, Apple/Epic, Bronner and Slovak Telekom demonstrate different dimensions of this problem: operating-system control, search ranking, ecosystem tying, app-store governance, infrastructure access and interoperability.
