Competition Law and Competition Implications of Transformation Concentration

1. Introduction

Transformation concentration refers to a situation in which market power becomes increasingly concentrated as an industry undergoes a major technological, structural, regulatory, or business-model transformation.

The term is particularly relevant to:

digital transformation;

artificial intelligence;

cloud computing;

platformisation;

fintech;

telecommunications;

e-commerce;

data-driven business models;

automation;

digital advertising;

software ecosystems; and

technology-enabled financial and infrastructure markets.

Transformation can change who controls the important inputs, distribution channels, data, technology, customers and infrastructure of an industry.

Thus, transformation concentration may be represented as:

Technological/structural transformation → consolidation of resources and capabilities → increased market power → greater concentration → potential competition concerns

Importantly, concentration itself is not automatically unlawful. Competition law generally asks whether the transformation has resulted in, or is likely to result in, substantial restriction of competition, abuse of dominance, exclusion of competitors, or an anti-competitive combination.

2. Meaning of Transformation Concentration

Transformation concentration has two related dimensions.

A. Transformation of the market

An industry changes because of:

digitisation;

AI;

automation;

platform business models;

cloud infrastructure;

new distribution systems;

regulatory changes;

technological innovation.

B. Concentration resulting from transformation

The transformation may disproportionately benefit a small number of firms because they already possess:

capital;

data;

infrastructure;

patents;

computing capacity;

users;

distribution networks;

technical expertise;

established ecosystems.

Consequently, transformation can create a self-reinforcing concentration process.

3. Transformation Concentration and Competition Law

Competition law traditionally focuses on:

anti-competitive agreements;

abuse of dominant position; and

mergers and combinations.

Transformation concentration can affect all three.

For example:

Digital transformation

↓

Large platform obtains more users

↓

More data and economies of scale

↓

Higher quality/service advantages

↓

Competitors face greater entry barriers

↓

Market becomes more concentrated

Competition authorities may then examine whether the resulting conduct or transaction harms competition.

4. Major Forms of Transformation Concentration

4.1 Digital Transformation Concentration

Digital transformation can shift markets from traditional businesses to platform-based ecosystems.

Examples include:

physical retail → e-commerce;

newspapers → digital media;

traditional advertising → programmatic advertising;

banking → fintech;

physical software → cloud software;

conventional entertainment → streaming.

The firms controlling the new digital infrastructure may acquire substantial market power.

5. Data Transformation Concentration

Data is increasingly an important competitive asset.

A firm with a large user base may collect:

search data;

purchasing information;

behavioural data;

location data;

advertising data;

transaction information.

This can generate:

more users → more data → better services → more users.

This feedback mechanism can make concentration persistent.

6. AI Transformation Concentration

Artificial intelligence can produce new forms of concentration around:

computing power;

specialised chips;

cloud infrastructure;

training data;

foundation models;

AI talent;

distribution platforms.

A small number of firms may control several levels of the AI supply chain.

For example:

chips → cloud computing → training infrastructure → foundation model → application platform

Vertical integration across these levels can create competition concerns if a firm has the ability and incentive to restrict competitors' access.

7. Cloud Transformation Concentration

Cloud computing has transformed IT infrastructure from company-owned servers to externally supplied computing resources.

Large cloud providers may control:

computing capacity;

storage;

databases;

AI infrastructure;

software tools;

developer ecosystems.

The European Commission has recently examined the competitive importance of cloud services. In June 2026 it announced a preliminary view that Amazon Web Services and Microsoft Azure should be designated as Digital Markets Act gatekeepers because of their role as important gateways and their entrenched positions and switching-cost effects. (Digital Markets Act (DMA))

This illustrates how technological transformation can create new forms of infrastructural concentration.

8. Platform Transformation

Traditional businesses often operated through relatively simple supplier-consumer relationships.

Platforms create multi-sided markets involving:

consumers;

sellers;

advertisers;

developers;

content creators;

payment providers.

The platform can become a gatekeeper between different groups.

This can create concentration because users and businesses may find it costly to leave the ecosystem.

9. Network Effects

Network effects are central to transformation concentration.

Direct network effect

The value of a service increases as more users join.

Example:

More users → more valuable network → more users.

Indirect network effect

More users attract complementary businesses, which further increase the platform's attractiveness.

Example:

More consumers → more sellers → more products → more consumers.

Network effects can therefore make markets tip toward a small number of firms.

10. Economies of Scale

Digital transformation can substantially reduce the marginal cost of serving additional customers.

A technology company may spend enormous amounts initially on:

software;

data centres;

AI models;

research;

security.

But once the infrastructure exists, serving additional customers may be relatively inexpensive.

This creates economies of scale and can increase concentration.

11. Switching Costs and Lock-In

Transformation can also increase switching costs.

Examples include:

proprietary software;

cloud contracts;

ecosystem-specific applications;

accumulated data;

compatibility problems;

training costs;

contractual commitments.

A customer may therefore remain with an incumbent even when competitors offer alternatives.

12. Interoperability Problems

A transformation leader may control the interfaces necessary for competitors to interact with its ecosystem.

Examples include:

APIs;

operating systems;

payment systems;

app stores;

cloud interfaces;

messaging systems.

Refusing interoperability or providing inferior interoperability can potentially disadvantage competitors.

13. Self-Preferencing

A vertically integrated platform may compete with businesses that depend upon its platform.

The platform may potentially:

rank its own products more favourably;

provide better access to its own services;

use data from competitors;

impose discriminatory conditions.

Such conduct can raise competition concerns where it produces exclusionary effects.

14. Killer Acquisitions and Transformation

Transformation creates another important issue: acquisition of emerging competitors.

A large incumbent may acquire:

a small innovative company;

a potential future competitor;

a new technology;

an important data asset;

an emerging AI developer.

The acquired firm may currently have limited revenue, but it may have substantial future competitive significance.

This is why modern merger control increasingly examines potential competition and innovation effects.

15. Case Law 1 — United States v. Microsoft

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

Microsoft controlled the Windows operating-system ecosystem.

The case concerned Microsoft's conduct toward emerging technologies, particularly Netscape's browser and Java.

The court found that Microsoft had engaged in exclusionary conduct that maintained its operating-system monopoly.

Relevance to transformation concentration

The case demonstrates how technological transformation can create a powerful ecosystem around an established platform.

The important competition issue was not simply Microsoft's size but the use of its position to protect the existing ecosystem from technological developments that could threaten its position.

Principle

Technological leadership can become a competition concern when control over an ecosystem is used to suppress emerging competitive pathways.

16. Case Law 2 — Google Shopping

Google Search (Shopping), Case AT.39740

The European Commission found that Google had abused its dominant position in general search by giving preferential treatment to its comparison-shopping service in search results.

The case is important for transformation concentration because Google operated simultaneously as:

search infrastructure;

information intermediary; and

provider of its own specialised service.

Competition significance

The case illustrates the risk of platform power being extended into adjacent markets.

A transformed digital market can therefore generate concerns where the platform controlling access to consumers also competes against the businesses using that platform.

17. Case Law 3 — Microsoft v Commission

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

Microsoft's control over the Windows ecosystem gave it significant technological power.

The European Commission found that Microsoft had abused its dominant position, including through conduct concerning interoperability information.

The General Court substantially upheld the Commission's findings.

Significance

The case demonstrates that technological transformation can make interoperability information a strategically important competitive resource.

Control over a technological ecosystem can therefore affect competition in related markets.

18. Case Law 4 — Bronner v Mediaprint

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

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

The Court adopted a stringent approach to compulsory access to infrastructure.

The relevant considerations included:

indispensability;

absence of a realistic alternative;

possible elimination of competition; and

lack of objective justification.

Relevance to transformation concentration

The case establishes an important limitation:

A firm does not automatically have to share every resource that competitors find commercially useful.

This principle is particularly important when new technology creates expensive infrastructure.

19. Case Law 5 — Commercial Solvents

Commercial Solvents Corp. and Istituto Chemioterapico Italiano v Commission, Joined Cases 6/73 and 7/73

Commercial Solvents controlled an important raw material and restricted supplies to a downstream competitor.

The European Court treated the conduct as capable of constituting an abuse of dominance.

Relevance

The case illustrates input foreclosure.

Where transformation causes a firm to become dominant over an important input, it may have the ability to disadvantage downstream competitors.

20. Case Law 6 — Intel

Intel Corp. v Commission, Case C-413/14 P

The case concerned rebates offered by Intel to major computer manufacturers and retailer MSH.

The Court of Justice required a more detailed examination of whether the rebates were capable of restricting competition where the dominant undertaking disputed that they had exclusionary effects.

Relevance to transformation concentration

The case demonstrates that competition analysis should not simply assume that conduct is harmful because it comes from a dominant company.

Authorities may need to examine:

actual or potential foreclosure;

market coverage;

duration;

conditions;

competitors' ability to compete;

economic effects.

21. Case Law 7 — Microsoft/Activision Blizzard

Microsoft / Activision Blizzard

The transaction raised important questions about concentration in gaming ecosystems, particularly concerning cloud gaming and access to content.

The UK's Competition and Markets Authority initially opposed the transaction, while subsequent developments and remedies changed the regulatory assessment. The CMA's case record identifies the transaction as a major Phase 2 merger inquiry. (GOV.UK)

Competition significance

The case illustrates how technological transformation can make ecosystem effects more important than traditional market-share analysis alone.

Relevant issues included:

gaming content;

cloud gaming;

distribution;

platform ecosystems;

future competition.

It is therefore a useful example of dynamic competition analysis.

22. Case Law 8 — Adobe/Figma

Adobe / Figma merger

Adobe proposed acquiring Figma, a collaborative design software platform.

The transaction attracted competition scrutiny because Figma was an important emerging technology platform and potential competitive constraint.

The European Commission prohibited the transaction in 2023, while the UK CMA's investigation also concluded with the transaction being abandoned. The CMA records the case as a Phase 2 cancellation. (GOV.UK)

Significance

The case demonstrates that competition authorities may examine whether acquisition of an innovative platform could remove an important source of future competition.

23. Case Law 9 — Amazon/CCI

Amazon.com NV Investment Holdings LLC v Competition Commission of India

This is particularly relevant to Indian competition law.

In 2026, the Supreme Court of India considered the CCI's proceedings concerning Amazon's disclosure of the substance and structure of its proposed combination involving Future Coupons.

The Court emphasised that merger control is forward-looking and that notification must disclose the transaction in its commercial substance, including interconnected arrangements and rights. (Indian Kanoon)

Relevance to transformation concentration

Modern corporate transformations can occur through complex arrangements rather than simple acquisitions.

Competition authorities therefore need sufficient information to assess:

control;

economic relationships;

interconnected transactions;

future market structure.

24. Transformation Concentration and Section 3 of the Indian Competition Act

Under Section 3 of the Competition Act, 2002, agreements that cause or are likely to cause an appreciable adverse effect on competition may be prohibited.

Transformation can create opportunities for competitors to coordinate around:

technical standards;

data;

algorithms;

interoperability;

platforms;

digital infrastructure.

Agreements restricting access to transformed markets may therefore attract scrutiny.

25. Transformation Concentration and Section 4

Section 4 deals with abuse of dominant position.

Potentially relevant conduct includes:

discriminatory conditions;

denial of market access;

limiting technical development;

restricting production;

leveraging dominance;

unfair conditions.

Transformation concentration becomes particularly important when a company controls a gateway through which competitors must reach customers.

26. Transformation Concentration and Merger Control

Sections 5 and 6 of the Competition Act address combinations.

A transformation-related acquisition can create:

Horizontal concentration

Competitor + competitor

Vertical concentration

Supplier + distributor

Conglomerate concentration

Platform + complementary service

Ecosystem concentration

Platform + potential future competitor

The last category is increasingly important in technology markets.

27. Dynamic Competition

Traditional competition analysis may focus heavily on:

current market share;

current prices;

current competitors.

Transformation markets require additional attention to:

innovation;

future entry;

technology development;

data accumulation;

network effects;

switching costs;

ecosystem expansion.

Thus:

Static competition = competition today.

Dynamic competition = competition today + future competitive possibilities.

28. Innovation Competition

A transformed market may have rapid technological development.

A company with a large market share today may face disruption tomorrow.

However, if the incumbent acquires or excludes emerging technologies, the competitive process itself may be weakened.

Therefore, competition authorities may ask:

Would the emerging firm have become an important competitive constraint if the transaction or conduct had not occurred?

This is particularly relevant to digital and AI markets.

29. Ecosystem Concentration

Modern firms increasingly operate ecosystems rather than single-product businesses.

For example:

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

Control over several connected services can create ecosystem concentration.

An ecosystem may produce:

cross-service data advantages;

common customer accounts;

interoperability advantages;

cross-subsidisation;

preferential ranking;

reduced switching.

30. Cloud and AI as Emerging Transformation Concentration

Cloud and AI illustrate the modern problem particularly well.

A company may simultaneously control:

computing infrastructure;

cloud distribution;

AI development tools;

foundation models;

application distribution;

customer relationships.

This creates the possibility of vertical and ecosystem concentration.

The EU's 2026 cloud investigations illustrate the growing regulatory attention to cloud computing as a strategic gateway. (Digital Markets Act (DMA))

31. Consumer Effects

Transformation concentration can affect consumers through:

Positive effects

lower prices;

improved quality;

faster innovation;

convenience;

integrated services;

greater reliability.

Potential negative effects

higher prices;

reduced choice;

reduced privacy;

lower innovation;

switching costs;

reduced service quality;

dependence on one ecosystem.

Competition law generally examines these effects rather than assuming that concentration is automatically harmful.

32. Barriers to Entry

Transformation can produce new barriers such as:

enormous capital requirements;

data advantages;

network effects;

patents;

cloud infrastructure;

technical expertise;

brand recognition;

switching costs;

regulatory approvals.

These barriers can make it difficult for new entrants to challenge an established firm.

33. Transformation Concentration and Self-Reinforcement

A major characteristic is self-reinforcing concentration.

For example:

Large user base

↓

More data

↓

Better algorithms

↓

Better products

↓

More users

↓

Higher revenues

↓

More investment

↓

Stronger market position

This cycle can make market power increasingly difficult to challenge.

34. Possible Competition-Law Remedies

If anti-competitive conduct is established, authorities may consider:

Behavioural remedies

non-discriminatory access;

interoperability;

data portability;

prohibition of self-preferencing;

fair ranking;

restrictions on exclusivity.

Structural remedies

divestiture;

separation of business units;

infrastructure separation.

Merger remedies

licensing;

access commitments;

divestiture;

interoperability commitments;

restrictions on exclusive arrangements.

Regulatory remedies

Digital markets may additionally be subject to specialised ex-ante regulation. The EU's Digital Markets Act, for example, imposes obligations on designated gatekeepers. Six major companies were initially designated in 2023, including Alphabet, Amazon, Apple, ByteDance, Meta and Microsoft. (Digital Markets Act (DMA))

35. Challenges for Competition Authorities

35.1 Rapid technological change

By the time an investigation finishes, technology may have changed substantially.

35.2 Difficult market definition

Digital ecosystems may span several interconnected markets.

35.3 Zero-price services

Consumers may pay with data or attention rather than money.

35.4 Innovation uncertainty

It can be difficult to determine what technology will become important in the future.

35.5 Algorithmic complexity

Algorithms can produce competitive effects that are difficult to observe.

35.6 Cross-market effects

A company may use strength in one market to expand into another.

36. Transformation Concentration vs Traditional Market Concentration

37. Key Legal Principles

The following principles are particularly useful:

Principle 1

Concentration itself is not automatically unlawful.

Principle 2

Competition law examines whether concentration produces or facilitates market power and anti-competitive effects.

Principle 3

Control of a gateway or bottleneck can create special competition concerns.

Principle 4

Network effects and switching costs can make transformation-related market power durable.

Principle 5

Innovation and potential competition must be considered.

Principle 6

Compulsory access to infrastructure is generally subject to important legal limitations.

Principle 7

Merger control is increasingly concerned with future competitive constraints, not merely current market shares.

38. Conclusion

Transformation concentration describes the concentration of competitive power that can emerge when an industry undergoes technological, digital, financial, infrastructural or business-model transformation.

Its competition-law importance arises because transformation can cause control over data, technology, cloud infrastructure, platforms, AI capabilities, distribution channels and ecosystems to become concentrated in a small number of firms.

The central competition-law questions are:

Who controls the transformed infrastructure?

Does that control create substantial market power?

Are competitors dependent upon the resource or platform?

Are network effects and switching costs creating durable advantages?

Is the dominant firm excluding competitors?

Is an acquisition eliminating potential competition?

Is innovation being protected or restricted?

Are there legitimate efficiencies or investment incentives?

What is the likely effect on consumers and future competition?

What remedy would preserve competition without unnecessarily discouraging innovation?
