Competition Law and Information Intermediary Monopolies

1. Introduction

Information intermediaries are businesses or platforms that stand between information producers, consumers, advertisers, researchers, businesses, or other market participants and control how information is collected, organized, ranked, filtered, distributed, verified, or accessed.

Examples include:

search engines;

online marketplaces;

app stores;

news aggregators;

comparison-shopping services;

digital advertising exchanges;

business-information databases;

credit-information systems;

recommendation and ranking platforms;

social-media information networks;

data brokers;

identity and authentication intermediaries; and

AI systems that increasingly mediate access to information.

An information intermediary monopoly arises where one undertaking obtains substantial or durable market power over an information gateway and competitors, suppliers, or users become dependent upon that gateway.

The competition-law problem is not simply that an intermediary is large. Competition law generally permits firms to acquire market power through innovation and superior products. The concern arises when control over the information gateway is used to exclude competitors, discriminate between users, raise rivals' costs, exploit dependencies, restrict interoperability, foreclose access to data, or extend dominance into adjacent markets.

Modern digital markets make this issue particularly significant because information intermediaries can benefit simultaneously from network effects, data advantages, economies of scale, switching costs, algorithms, default positions and ecosystem integration. The EU's current Digital Markets Act framework, for example, designates major services such as Google Search, Google Shopping, Google Play, Amazon Marketplace, Apple's App Store, Booking's online intermediation service and Microsoft's LinkedIn as core platform services of designated gatekeepers. (Digital Markets Act (DMA))

2. Meaning of an Information Intermediary

An information intermediary performs one or more of the following functions:

Information aggregation – collecting information from numerous sources.

Information ranking – deciding which information users see first.

Information filtering – determining what information is displayed or suppressed.

Information verification – certifying or authenticating information.

Information matching – connecting buyers and sellers, users and providers, or advertisers and audiences.

Information discovery – allowing users to locate products, services or content.

Information distribution – determining how information reaches users.

Data intermediation – controlling access to commercially valuable datasets.

Identity intermediation – authenticating users or transactions.

Algorithmic intermediation – using automated systems to determine visibility, ranking or access.

The intermediary therefore may not manufacture the underlying product. Its competitive importance comes from controlling access to information about the product or access to users interested in the product.

3. Why Information Intermediaries Can Become Monopolistic

A. Network effects

An information intermediary becomes more valuable as participation increases.

For example:

More users → more information → better search/matching → more users → more suppliers → more information.

This creates a self-reinforcing cycle.

A new entrant may therefore face a structural problem: even if its technology is comparable, it lacks the installed user and information base of the incumbent.

B. Data advantages

Large intermediaries can accumulate:

search histories;

transaction data;

clickstream information;

consumer preferences;

location information;

supplier information;

advertising data;

behavioural information; and

interaction data.

Data itself is not automatically an essential facility or legally protected monopoly resource. The relevant question is whether the particular dataset, combined with other characteristics, creates a significant competitive barrier.

The OECD has noted the continuing debate over whether particular datasets can constitute indispensable inputs, emphasizing that the competitive significance of data depends on factors such as substitutability, scale and scope. (OECD ONE MP)

4. Relevant Market Definition

An information intermediary may operate across several interconnected markets.

For example, a search intermediary may participate in:

general search services;

search advertising;

comparison-shopping;

advertising technology;

data services;

mapping;

video;

cloud services; and

AI-based information retrieval.

Competition authorities therefore need to determine whether the relevant market should be:

A. Broad

For example:

digital information-intermediation services.

or

B. Narrow

For example:

general search services.

or:

online comparison-shopping intermediation.

or:

app distribution services for mobile devices.

Market definition can substantially affect the assessment of dominance.

5. Monopoly Power Is Not Itself Illegal

This distinction is fundamental.

Competition law normally does not prohibit:

successfully becoming large.

It prohibits certain forms of anticompetitive acquisition, maintenance or exploitation of market power.

In the United States, monopoly power is traditionally associated with the ability to control prices or exclude competition. The recent Google search judgment, for example, analyzed monopoly power by reference to relevant markets, market structure, entry barriers and exclusionary conduct. (FindLaw)

Under EU law, Article 102 TFEU similarly concerns abuse of a dominant position, rather than dominance as such.

Under India's Competition Act, 2002, Section 4 prohibits abuse of dominant position rather than dominance itself.

6. Main Competition Concerns

A. Self-preferencing

An intermediary may place its own products or services above competing products.

Example:

Search intermediary → controls ranking → owns comparison-shopping service → gives its own service preferential visibility.

This was central to the Google Shopping litigation.

The General Court described the issue as Google's treatment of its own comparison-shopping service more favourably than competing comparison-shopping services in general search results. (Eur-Lex)

Self-preferencing becomes particularly problematic where competitors depend upon the intermediary for traffic.

7. Refusal to Provide Access

An intermediary may refuse competitors access to:

APIs;

databases;

search indexing;

interoperability information;

authentication systems;

distribution infrastructure;

technical interfaces;

transaction data; or

other critical information.

But not every refusal is unlawful.

The European essential-facilities jurisprudence generally requires a demanding assessment of indispensability and competitive foreclosure. The classic Bronner framework is intended to protect both competition and a dominant firm's incentives to invest in infrastructure. (Eur-Lex)

8. Information as an Essential Facility

The essential facilities doctrine asks, in simplified terms, whether a dominant undertaking controls an input or infrastructure that competitors genuinely cannot reasonably duplicate or substitute.

Traditional examples concern physical infrastructure.

In digital markets, potential facilities may include:

dominant search indexes;

interoperability information;

critical databases;

identity infrastructure;

APIs;

app distribution systems;

digital advertising infrastructure; and

certain forms of commercially indispensable data.

However, courts have been cautious about automatically treating data or digital platforms as essential facilities.

The European case law has developed different formulations in Bronner, Magill, IMS Health and Microsoft. (Springer)

9. Tying and Bundling

An information intermediary may leverage its position in one market into another.

For example:

dominant search service
↓
browser
↓
operating system
↓
advertising service

or:

dominant app store
↓
payment service
↓
app distribution

The concern is that users or businesses may be forced to use the intermediary's adjacent product.

10. Exclusive Dealing

An intermediary may enter agreements requiring:

exclusivity;

default placement;

minimum use;

preferential distribution;

restrictions on rival intermediaries; or

contractual limitations on multi-homing.

These arrangements may be particularly important where the intermediary controls a bottleneck.

A contract that looks commercially ordinary can have exclusionary effects when concluded by an undertaking with substantial market power.

11. Ranking and Algorithmic Discrimination

Information intermediaries frequently control visibility through algorithms.

An intermediary could potentially manipulate:

search rankings;

recommendation systems;

advertising auctions;

product placement;

app rankings;

news feeds;

marketplace listings;

price-comparison results.

Competition law therefore increasingly has to distinguish legitimate algorithmic optimization from strategic algorithmic discrimination against competitors.

The Google Shopping litigation illustrates this problem: the legal issue concerned not simply ownership of a search engine but the competitive consequences of the way its results were positioned and displayed. (Eur-Lex)

12. Data Foreclosure

A dominant intermediary may possess information that rivals require to compete effectively.

Possible practices include:

withholding data;

providing inferior data access;

discriminatory API access;

restricting portability;

preventing interoperability;

imposing excessive access charges;

limiting third-party data use; or

combining datasets unavailable to competitors.

This can produce a data foreclosure effect.

However, the mere possession of a large dataset does not automatically establish dominance or an abuse.

13. Switching Costs and Lock-In

Information intermediaries may create significant switching costs.

Users may lose:

search histories;

ratings;

reputation;

transaction records;

contacts;

preferences;

stored data;

integrations;

business relationships.

For businesses, switching can also require:

retraining employees;

rewriting software;

changing APIs;

migrating databases;

rebuilding customer relationships; and

changing contractual arrangements.

Consequently, even a nominally free service can possess substantial competitive advantages.

14. Interoperability

Interoperability is particularly important where one intermediary becomes a gateway.

Competition concerns may arise if a dominant undertaking:

prevents interoperability;

degrades interoperability;

delays access;

changes technical specifications selectively;

restricts APIs;

imposes discriminatory technical conditions; or

makes switching technically difficult.

The Microsoft case is especially important because the EU courts accepted that Microsoft's refusal to provide interoperability information could contribute to exclusion of competitors. The case has therefore become a major reference point for digital bottleneck analysis. (Springer)

15. Information Intermediary Monopolies and Artificial Entry Barriers

An incumbent can reinforce its position through:

control over standards;

proprietary interfaces;

exclusive contracts;

default settings;

technical incompatibility;

control over distribution;

data accumulation;

acquisitions of potential competitors;

ecosystem integration.

This creates strategic entry barriers.

The critical competition-law question becomes:

Is the intermediary's advantage the legitimate result of innovation and investment, or is it being artificially protected through exclusionary conduct?

16. Six Important Case Laws

1. United States v. Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001)

Facts

Microsoft possessed substantial power in the market for Intel-compatible PC operating systems.

The case concerned Microsoft's conduct involving Internet Explorer, Netscape and distribution arrangements.

Principle

The court examined exclusionary conduct designed to preserve Microsoft's operating-system monopoly.

The case demonstrated the importance of:

network effects;

entry barriers;

platform control;

technological integration;

exclusionary agreements; and

leveraging of platform power.

Relevance

It is highly relevant to information intermediaries because control over an information gateway can be used to disadvantage rival technologies.

2. Google Search (Shopping), European Commission / General Court

Facts

Google operated a dominant general search service and also operated its own comparison-shopping service.

The European Commission found that Google gave its comparison-shopping service favourable positioning and display while competing services received less favourable treatment.

The General Court subsequently considered the competitive significance of that conduct.

Principle

The case demonstrates that competition law can address discriminatory treatment by an intermediary where its ranking and traffic-allocation mechanisms advantage its own downstream service.

Relevance

It is one of the clearest examples of:

information gateway + self-preferencing + downstream foreclosure.

The EU court's discussion specifically concerned whether competing comparison-shopping services received treatment comparable to Google's own service. (Eur-Lex)

3. IMS Health GmbH & Co. OHG v NDC Health GmbH, C-418/01

Facts

IMS Health possessed intellectual-property rights relating to a pharmaceutical sales-information structure.

A competitor sought access to the relevant structure.

Principle

The Court of Justice developed stringent conditions for treating refusal to license intellectual property as an abuse.

The circumstances included:

indispensability;

elimination of effective competition;

prevention of a new product for which consumer demand existed; and

absence of objective justification.

Relevance

The case is important where an information intermediary controls a proprietary database, information architecture or other intellectual-property-protected information resource.

4. Magill TV Guide / RTE and ITP

Facts

Television broadcasters controlled copyright-protected programme information.

Magill sought to publish comprehensive television programme information.

Principle

The European courts recognized exceptional circumstances in which refusal to license intellectual property can constitute abuse of dominance.

Relevance

The case demonstrates the relationship between:

information;

intellectual property;

market access;

downstream innovation; and

dominance.

It is particularly useful when considering whether information controlled by a dominant intermediary can be withheld from downstream competitors.

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

Facts

Bronner operated a newspaper and sought access to Mediaprint's newspaper-delivery system.

Mediaprint controlled a substantial newspaper-distribution network.

Principle

The Court established stringent requirements for a refusal to supply to become abusive.

The facility generally must be genuinely indispensable, and the refusal must threaten elimination of effective competition, among other requirements.

Relevance

Although the case involved physical newspaper distribution, it has enormous significance for modern information intermediaries.

A digital platform cannot simply be labelled an "essential facility" merely because competitors would benefit from access.

The doctrine seeks to balance access against the dominant firm's property rights and incentives to invest. (Eur-Lex)

6. Microsoft Corp. v Commission, T-201/04

Facts

Microsoft possessed substantial power in PC operating systems and was accused of withholding interoperability information necessary for competing work-group server products.

Principle

The EU courts upheld the Commission's finding concerning Microsoft's refusal to provide interoperability information under the particular circumstances of the case.

Relevance

This is particularly important for modern information intermediaries because interoperability information itself can become competitively significant.

It illustrates how technological information can operate as a bottleneck between competing ecosystems.

7. Huawei Technologies Co. Ltd v ZTE Corp., C-170/13

Facts

The dispute concerned standard-essential patents and licensing.

Huawei sought enforcement of patent rights while ZTE relied on the framework applicable to standard-essential patents.

Principle

The Court developed a structured framework concerning when enforcement of standard-essential patent rights may amount to abuse of dominance.

Relevance

Information intermediaries frequently operate through technical standards.

Control over standards can therefore create:

interoperability power;

licensing leverage;

exclusionary possibilities; and

dependence on technical information.

8. Slovak Telekom v Commission, C-165/19 P

Facts

The case concerned access to telecommunications infrastructure and alleged exclusionary conduct.

Principle

The Court distinguished an outright refusal to deal from situations involving access conditions imposed by a dominant undertaking.

The modern EU jurisprudence therefore does not mechanically apply the strict Bronner criteria to every form of discriminatory or restrictive access conduct. (InfoCuria)

Relevance

This is important for information intermediaries because many digital disputes involve conditional or discriminatory access, rather than a simple absolute refusal.

17. Indian Competition Law Perspective

Information intermediary monopolies can be examined primarily under the Competition Act, 2002.

Important provisions include:

Section 3

Addresses agreements having or likely to have appreciable adverse effect on competition.

Potentially relevant conduct includes:

information-sharing arrangements;

exclusionary agreements;

market allocation;

discriminatory arrangements;

coordinated use of algorithms.

Section 4

Deals with abuse of dominant position.

Potential forms include:

unfair or discriminatory conditions;

unfair pricing;

limiting markets;

denial of market access;

leveraging dominance;

tying or bundling.

Sections 5 and 6

Merger-control provisions become relevant when an information intermediary seeks to acquire:

emerging competitors;

data-rich firms;

complementary platforms;

potential competitors; or

firms controlling strategically important information assets.

The CCI has already dealt extensively with digital-platform competition issues, including Google's position in mobile and app-distribution ecosystems. The CCI continues to publish antitrust proceedings involving major digital platforms. (Competition Commission of India)

18. Information Intermediaries as Gatekeepers

A particularly important concept is the gatekeeper.

A gatekeeper may control access between:

suppliers ↔ consumers

or:

information producers ↔ information consumers

or:

advertisers ↔ audiences

or:

applications ↔ users.

This creates bottleneck power.

The EU's Digital Markets Act expressly identifies certain core platform services operated by designated gatekeepers, including search, marketplaces, app stores, social networks and online intermediation services. (Digital Markets Act (DMA))

19. Information Intermediaries and the "Quasi-Essential Facility"

Digital platforms raise a new question:

Can a platform be so important to market access that competitors effectively cannot compete without it?

Google Search has generated particular discussion because competing comparison-shopping services depended substantially upon traffic from the search engine. The EU litigation examined the significance of Google's search-result positioning rather than simply treating access to the search engine as a traditional physical essential facility. (Eur-Lex)

This suggests a potentially broader concept of digital bottleneck power, although the legal requirements for an essential-facilities finding remain demanding.

20. Monopoly Through Information Asymmetry

Information intermediaries can possess information about both sides of a market.

For example, an intermediary might know:

consumer demand;

supplier costs;

consumer preferences;

competitor performance;

transaction volumes;

conversion rates;

advertising effectiveness.

If the intermediary competes downstream, it may potentially use this information to compete against the very businesses that depend upon it.

This creates a potential information asymmetry problem:

Intermediary knows the market → intermediary observes participants → intermediary competes with participants → intermediary can potentially use informational advantages against them.

Competition authorities therefore increasingly examine data access and information advantages alongside conventional market-share analysis.

21. Algorithmic Intermediation

An information intermediary may use algorithms to determine:

which seller appears first;

which advertisement is displayed;

which application is recommended;

which news article is visible;

which product receives traffic;

which user receives an offer.

Algorithmic control can create a form of automated market allocation.

Potential competition concerns include:

algorithmic self-preferencing;

discriminatory ranking;

exclusionary recommendation systems;

algorithmic tying;

discriminatory access;

coordinated pricing;

manipulation of advertising auctions; and

restriction of interoperability.

The legal analysis still requires evidence of market power, exclusionary effects and the applicable statutory elements; algorithmic operation by itself does not establish an infringement.

22. Merger Control and Information Intermediaries

Traditional merger thresholds can sometimes fail to capture the competitive importance of digital acquisitions because an emerging information intermediary may have:

little revenue;

rapid user growth;

valuable data;

innovative technology;

substantial network effects.

Consequently, authorities may examine acquisitions involving:

data assets;

AI companies;

search technologies;

recommendation systems;

identity systems;

advertising technologies;

interoperability tools.

The central concern is whether acquisition of a potential competitor allows an incumbent information intermediary to eliminate a future competitive constraint.

23. Remedies

Competition authorities may consider several remedies.

Structural remedies

In exceptional circumstances:

divestiture;

separation of business units;

restrictions on acquisitions.

Behavioural remedies

More commonly:

non-discriminatory access;

interoperability;

data portability;

API access;

prohibition of self-preferencing;

transparency requirements;

non-exclusive contracts;

restrictions on tying;

ranking neutrality;

fair access conditions.

Regulatory remedies

Digital-market legislation can impose ex ante obligations on gatekeepers without requiring authorities to prove every individual instance of traditional abuse.

This is particularly relevant because conventional abuse-of-dominance proceedings can take years while digital markets may change rapidly.

24. Important Legal Tensions

Information intermediary regulation must balance competing objectives.

Competition versus innovation

Forced access can help competitors but may reduce incentives to build new infrastructure.

Access versus property rights

A dominant intermediary may have legitimate interests in controlling its technology.

Transparency versus algorithmic integrity

Full disclosure of ranking algorithms could facilitate gaming or manipulation.

Data sharing versus privacy

Competition remedies involving data must also respect data-protection obligations.

Interoperability versus cybersecurity

Opening APIs and interfaces can increase competition but may introduce security risks.

Short-term access versus long-term competition

An access remedy may help existing competitors without necessarily creating sustainable independent competition.

25. Key Principles Emerging from the Case Law

The case law collectively suggests several important propositions:

Size alone does not establish unlawful monopoly.

Market power must be assessed in a properly defined relevant market.

Control of an information gateway can create substantial competitive leverage.

Self-preferencing may become problematic when a dominant intermediary discriminates against downstream competitors.

Refusal to deal is generally subject to demanding legal requirements.

Indispensability is particularly important in traditional essential-facilities cases.

Interoperability information can have major competitive significance.

Intellectual-property rights do not provide absolute immunity from competition law.

Network effects and switching costs can reinforce market power.

Data advantages may contribute to entry barriers but do not automatically constitute an essential facility.

Exclusive agreements can reinforce an intermediary's position when rivals depend upon the intermediary for access to customers.

Merger control is important where acquisitions eliminate emerging competitive constraints.

26. Conclusion

Information intermediary monopolies represent a distinctive form of modern market power. Unlike a traditional monopolist that controls the physical production of a commodity, an information intermediary may control the gateway through which consumers, businesses and information providers discover and interact with one another.

The principal competition concerns are therefore:

control over information flows;

self-preferencing;

discriminatory ranking;

refusal of access;

interoperability restrictions;

data foreclosure;

exclusive dealing;

tying and bundling;

network effects;

switching costs;

algorithmic discrimination;

leveraging into adjacent markets; and

acquisitions of potential competitors.

The cases of Microsoft, Google Shopping, Magill, IMS Health, Bronner, Huawei v ZTE and Slovak Telekom provide important legal foundations for analysing these issues. The essential-facilities jurisprudence also demonstrates that courts generally distinguish between a facility that is merely useful and one that is genuinely indispensable. (Eur-Lex)

The central competition-law challenge is consequently not whether information intermediaries should be large, but whether control over an information bottleneck is being used in a manner that prevents effective competition, forecloses rivals, or extends market power into neighbouring markets.
