Hybrid State–Private Platform Monopolies in Digital Services

1. Introduction

Hybrid state–private platform monopolies arise where a digital platform is operated, controlled, financed, regulated, or substantially enabled through a combination of government authority and private enterprise, producing a position of exceptional market power.

The important feature is not simply that the State owns part of the platform. The more difficult competition-law problem arises when public authority and private economic power reinforce each other. A government may provide the platform with statutory privileges, exclusive access to public data, infrastructure, licences, procurement advantages, regulatory protection, or compulsory participation, while the private participant contributes technology, capital, algorithms, data analytics, cloud infrastructure, or commercial distribution.

Examples can include:

• digital identity and authentication ecosystems;
• government-backed payment platforms;
• public-private digital marketplaces;
• smart-city platforms;
• health-data exchanges;
• transport and mobility platforms;
• digital procurement systems;
• telecommunications infrastructure;
• government-supported cloud or AI infrastructure;
• public digital advertising or information platforms;
• state-backed data and interoperability networks.

The central competition-law question is:

When does legitimate public participation in a digital market become a mechanism for creating or protecting private market power?

2. Meaning of a Hybrid State–Private Platform Monopoly

A hybrid state–private platform monopoly can be understood as a market structure containing three interconnected elements:

A. State involvement

The government may:

• own shares;
• establish the platform by legislation;
• grant an exclusive licence;
• control essential infrastructure;
• mandate interoperability;
• provide public funding;
• supply government-generated data;
• designate the platform as a national infrastructure;
• compel users or businesses to participate.

B. Private commercial participation

A private undertaking may:

• operate the technical infrastructure;
• provide cloud services;
• supply algorithms;
• process transactions;
• monetize data;
• provide advertising;
• control interfaces;
• determine ranking or access;
• develop AI systems.

C. Platform-based market power

The resulting platform may benefit from:

• network effects;
• economies of scale;
• data advantages;
• switching costs;
• interoperability advantages;
• ecosystem effects;
• behavioural lock-in;
• regulatory barriers to entry.

The resulting monopoly may therefore be neither purely governmental nor purely private.

3. Why Digital Platforms Make the Problem More Serious

Traditional monopolies normally depend upon control over physical infrastructure or production capacity.

Digital platforms can obtain dominance through data, algorithms, standards and network effects.

A hybrid platform can therefore combine:

State authority + public infrastructure + private technology + data + network effects

to produce unusually durable market power.

For example:

Government designates a digital platform as essential infrastructure → millions of users are required or strongly encouraged to use it → private operator receives transaction data → data improves algorithms → better algorithms attract more users → competitors cannot obtain equivalent data → network effects strengthen the incumbent.

This creates a self-reinforcing monopoly loop.

4. Principal Competition-Law Concerns

A. Preferential regulatory treatment

A State may unintentionally or deliberately favour the hybrid platform through:

• exclusive licences;
• preferential certification;
• exemptions;
• government procurement;
• regulatory approvals;
• access to public infrastructure.

The private operator consequently competes under conditions unavailable to rivals.

This raises concerns of competitive neutrality.

B. Preferential access to government data

Data may be an essential competitive input.

A hybrid platform might receive:

• identity information;
• transport data;
• health information;
• financial information;
• geographic data;
• public procurement information;
• consumer information.

If competitors cannot obtain comparable data, the platform may develop a substantial informational advantage.

The issue becomes particularly serious where data is continuously generated by public infrastructure.

C. Network effects

Digital platforms often become more valuable as participation increases.

For example:

More users → more transactions → more data → better algorithms → better service → more users

A State-backed platform can accelerate this process by requiring public bodies or regulated entities to participate.

Private competitors may therefore face a market that is effectively closed before they can achieve sufficient scale.

5. Abuse of Dominance

Once the hybrid platform becomes dominant, competition law may address its conduct independently from the legality of its original creation.

Potential abuses include:

1. Self-preferencing

The platform may favour:

• its own applications;
• affiliated businesses;
• its own payment system;
• its own cloud service;
• its own search results;
• its own AI products.

2. Discriminatory access

Independent businesses may receive:

• slower API access;
• inferior interoperability;
• higher fees;
• reduced data access;
• inferior ranking.

3. Excessive or discriminatory charges

A platform controlling essential digital infrastructure may impose unreasonable access fees.

4. Data leveraging

The platform may combine data obtained from its public function with commercially collected data to strengthen unrelated businesses.

5. Tying and bundling

Access to an essential public-private service may be conditioned upon purchasing another private service.

6. Exclusivity

The platform may prevent users or business partners from using competing platforms.

6. State Measures and Article 106 TFEU

European competition law provides a particularly important framework.

Article 106 TFEU prevents Member States from maintaining measures concerning public undertakings or undertakings enjoying special or exclusive rights that conflict with EU competition rules.

This becomes highly relevant where the State gives a private or public-private digital platform:

• exclusive rights;
• regulatory privileges;
• monopoly infrastructure;
• preferential access;
• statutory protection.

The classic principle is that State-created monopoly power cannot automatically escape competition law merely because the State helped create it.

7. Six Major Case Laws

1. Höfner and Elser v Macrotron GmbH (1991)

Principle

The Court of Justice established that an entity exercising an economic activity can constitute an undertaking, regardless of its legal status or whether it is publicly controlled.

Relevance

This is fundamental for hybrid platforms.

A platform cannot necessarily escape competition law merely because:

• government created it;
• government owns it;
• it performs a public function.

If it engages in economic activity, competition rules can potentially apply.

Application

A state-private digital platform providing commercial:

• payment;
• cloud;
• advertising;
• marketplace;
• data;
• transport

services may therefore qualify as an undertaking in respect of those activities.

8. Merci Convenzionali Porto di Genova v Siderurgica Gabrielli (1991)

This case concerned an undertaking enjoying exclusive rights in port services.

Principle

The Court examined the interaction between:

• exclusive rights;
• State-created monopoly;
• abuse of dominant position.

A Member State cannot structure a monopoly in a manner that inevitably enables the undertaking to abuse its dominant position.

Digital relevance

The principle can translate into situations where the State grants a digital platform exclusive control over an infrastructure necessary for market participation.

For example:

State grants one platform exclusive control over a digital identity or transaction infrastructure → platform controls access for competing service providers → exclusionary conduct becomes structurally inevitable.

9. Corbeau (1993)

Principle

The Court recognised that certain exclusive rights may be justified where necessary to perform a service of general economic interest, subject to the limits of Article 106(2) TFEU.

Importance for digital platforms

This provides an important counterweight to a purely aggressive competition-law approach.

A government may legitimately establish a monopoly or exclusive system where necessary to provide an essential public service.

However, the exemption is not unlimited.

The State and platform must demonstrate that the restriction is genuinely necessary for the public service.

Digital example

A government-backed digital identity platform might legitimately require central coordination to guarantee:

• security;
• universal access;
• authentication;
• fraud prevention.

But that does not necessarily justify allowing the operator to use its monopoly position to dominate unrelated commercial markets.

10. Almelo v Energiebedrijf IJsselmij (1994)

Principle

The case concerned exclusive electricity distribution arrangements and the relationship between competition law and services of general economic interest.

The Court accepted that public-service objectives can justify certain restrictions but maintained that such restrictions must remain connected to the performance of the relevant public service.

Digital application

The case is particularly useful by analogy for:

• digital infrastructure;
• public cloud;
• telecommunications;
• smart-grid platforms;
• public digital exchanges.

A State may justify exclusive infrastructure control where technically necessary.

But:

Infrastructure monopoly ≠ unlimited commercial monopoly.

The operator should not automatically obtain unrestricted power over adjacent markets.

11. MOTOE v Elliniko Dimosio (2008)

Principle

This is one of the strongest authorities concerning a State-created conflict between regulatory authority and commercial activity.

The relevant organisation had regulatory powers while also engaging in economic activity.

The Court found that granting regulatory powers to an undertaking that competes in the same market can create a conflict capable of infringing competition law.

Digital significance

This is highly relevant to hybrid digital platforms.

Suppose a government gives a platform authority to:

• establish technical standards;
• approve competitors;
• certify users;
• determine interoperability;

while the same platform also sells commercial digital services.

The platform effectively becomes:

regulator + infrastructure operator + competitor.

That creates an inherent competitive neutrality problem.

12. Deutsche Telekom v Commission (2010)

Principle

The Court upheld the application of Article 102 TFEU to conduct involving a dominant telecommunications operator and recognised the significance of margin-squeeze analysis.

Digital-platform relevance

Telecommunications networks are often the foundational infrastructure for digital platforms.

A dominant infrastructure operator may potentially use control over an upstream layer to disadvantage competitors operating downstream.

The same structural logic can apply to hybrid digital ecosystems:

Essential infrastructure → platform access → downstream services

If the dominant operator sets upstream conditions that make viable downstream competition impossible, competition law may intervene.

13. Slovak Telekom v Commission (2021)

Principle

The Court considered refusal/access conditions concerning telecommunications infrastructure and the circumstances in which competition law may address access to infrastructure controlled by a dominant undertaking.

Digital relevance

The case provides an important framework for considering:

• network access;
• infrastructure bottlenecks;
• interoperability;
• technical access;
• downstream competition.

A hybrid public-private platform controlling an indispensable digital infrastructure may therefore face competition-law scrutiny when its access conditions exclude rivals.

14. Additional Relevant Case: Google Shopping

Principle

The Google Shopping litigation concerned the preferential treatment of the dominant platform's own comparison-shopping service.

The competition concern was not simply Google's size.

It was the possibility that a platform controlling an important gateway could use that position to favour its own downstream service.

Hybrid-platform relevance

The same theory can apply where a state-private platform simultaneously:

1. controls a digital gateway;
2. operates the infrastructure;
3. participates downstream; and
4. controls visibility or ranking.

This creates the possibility of platform-as-infrastructure plus platform-as-competitor discrimination.

15. Structural Problem: Regulatory Capture

A particularly serious risk is regulatory capture.

The private operator may become sufficiently important that government itself becomes dependent upon the platform.

The relationship can evolve:

State creates platform

↓

Platform acquires users

↓

Private operator acquires technical expertise

↓

Government becomes dependent on platform

↓

Platform influences regulatory standards

↓

Entry becomes more difficult

↓

Platform becomes quasi-essential

This creates a feedback mechanism between political power and economic power.

16. Competition Neutrality

The principle of competitive neutrality requires State ownership or governmental support not to confer unjustified competitive advantages.

A hybrid platform can violate competitive neutrality through:

The important question is therefore not merely:

"Is the platform government-owned?"

It is:

"Does State involvement materially distort the competitive conditions under which private rivals operate?"

17. Essential-Facility Dimension

Some hybrid platforms can become digital essential facilities.

Potential examples include:

• national payment infrastructure;
• identity authentication;
• interoperability networks;
• digital procurement infrastructure;
• telecommunications networks;
• public data exchanges.

Where refusal of access prevents effective competition, traditional essential-facility principles may become relevant.

However, not every important platform is automatically an essential facility.

Authorities must generally examine:

1. indispensability;
2. absence of realistic alternatives;
3. foreclosure;
4. duplication feasibility;
5. objective justification.

18. Data as a State-Private Monopoly Resource

One of the most distinctive features of hybrid digital monopolies is data concentration.

A private operator may simultaneously control:

• commercially generated data;
• government-provided data;
• platform-generated behavioural data;
• transaction data;
• metadata.

This creates a form of data vertical integration.

The competition problem becomes:

Public data → private analytics → market advantage → additional private data → stronger monopoly.

Therefore, data governance and competition policy increasingly overlap.

19. AI Intensifies the Problem

Hybrid state-private platforms become even more powerful when they incorporate AI.

A government-backed platform can possess:

• privileged datasets;
• public-sector computing resources;
• regulatory access;
• large user populations;
• proprietary AI models;
• behavioural data.

AI then transforms data advantages into:

• superior prediction;
• personalised pricing;
• automated ranking;
• fraud detection;
• credit scoring;
• demand forecasting;
• automated enforcement;
• algorithmic recommendations.

This may create algorithmic barriers to entry that competitors cannot easily reproduce.

20. The "Regulator–Operator–Competitor" Problem

The most dangerous institutional structure is:

Level 1 — Regulator

The State or state-authorised entity establishes market rules.

Level 2 — Infrastructure operator

The hybrid platform controls technical access.

Level 3 — Market participant

The same platform competes against private businesses using the infrastructure.

This produces a three-layer conflict:

Rule-making power + infrastructure power + commercial power

The MOTOE principle is particularly useful in analysing this structure.

21. Possible Competition-Law Remedies

Authorities may consider several remedies.

A. Non-discrimination obligations

Require equal treatment of competing businesses.

B. Interoperability

Require the platform to provide technical interoperability.

C. Data access

Permit competitors to obtain specified categories of data under fair conditions.

D. Functional separation

Separate:

• regulatory functions;
• infrastructure management;
• commercial operations.

E. Structural separation

In extreme circumstances, separate the infrastructure business from downstream commercial activities.

F. Transparency

Require disclosure of:

• ranking criteria;
• access rules;
• pricing methodology;
• API restrictions;
• technical standards.

G. Neutral procurement

Government contracts should be awarded through competitive and transparent procedures.

22. Key Legal Test

A useful analytical framework is:

Step 1 — Identify the undertaking

Is the platform engaging in an economic activity?

Step 2 — Identify State involvement

Determine whether the State provides:

• exclusive rights;
• funding;
• data;
• infrastructure;
• regulatory privileges.

Step 3 — Define the market

Consider:

• product/service market;
• geographic market;
• platform layers;
• upstream/downstream relationships.

Step 4 — Establish dominance

Analyse:

• market share;
• network effects;
• data;
• switching costs;
• entry barriers;
• ecosystem effects.

Step 5 — Identify the conduct

Look for:

• discrimination;
• self-preferencing;
• tying;
• refusal of access;
• exclusivity;
• predatory pricing;
• margin squeeze;
• data leveraging.

Step 6 — Examine State measures

Ask whether governmental measures:

• create;
• maintain;
• reinforce;
• facilitate

the dominant position.

Step 7 — Examine public-service justification

Determine whether the restriction is genuinely necessary for a legitimate public-service objective.

Step 8 — Select remedy

Possible remedies range from behavioural obligations to structural separation.

23. Consolidated Case-Law Table

24. Critical Legal Insight

The most important distinction is between public monopoly as a public-service instrument and publicly enabled private monopoly as a commercial advantage.

A State may legitimately create a centralised digital infrastructure when decentralisation would undermine:

• security;
• universal access;
• interoperability;
• national resilience;
• public-service delivery.

But the existence of a legitimate public objective does not automatically justify allowing a private operator to exploit the resulting infrastructure to dominate unrelated commercial markets.

Thus:

Public necessity may justify the infrastructure monopoly; it does not necessarily justify the downstream commercial monopoly.

25. Conclusion

Hybrid state-private platform monopolies represent a distinctive modern competition-law problem because political authority and private economic power can become mutually reinforcing.

The traditional distinction between:

• public monopoly, and
• private monopoly

becomes inadequate when a single digital ecosystem combines both.

The most significant competition concerns are:

1. State-created entry barriers;
2. preferential access to public data;
3. exclusive digital infrastructure;
4. network-effect amplification;
5. regulatory capture;
6. self-preferencing;
7. discriminatory interoperability;
8. data leveraging;
9. regulator–operator conflicts;
10. downstream foreclosure.

The case law from Höfner, Merci, Corbeau, Almelo and MOTOE, supplemented by infrastructure-access jurisprudence such as Deutsche Telekom and Slovak Telekom, demonstrates that the legal analysis must look beyond formal ownership.

The decisive question is how State authority interacts with economic activity and whether that interaction distorts competitive conditions.

In digital markets, the most dangerous form of hybrid monopoly is therefore not simply a government-owned platform. It is a platform that becomes simultaneously public infrastructure, private marketplace, data repository, technical standard-setter, and commercial competitor. That combination can transform ordinary market power into a form of institutionally protected digital dominance.
