Global Convergence of Digital Competition Rules

Introduction

Global convergence of digital competition rules refers to the increasing similarity among competition-law systems in different jurisdictions when addressing the economic power of large digital platforms, online marketplaces, app stores, search engines, digital advertising systems, cloud services, data-driven businesses, and artificial-intelligence ecosystems.

Historically, competition law was largely designed around conventional concepts such as price, market share, output, barriers to entry and consumer welfare. Digital markets have challenged these assumptions because services may be offered at zero monetary prices, markets are multi-sided, data can be an important competitive input, network effects can rapidly produce dominance, and platforms may simultaneously act as intermediaries, competitors and regulators of their own ecosystems.

Despite differences between the EU, United States, United Kingdom, Australia, Japan, China, India and other jurisdictions, there is now substantial convergence around several principles:

1. digital platforms can possess substantial market power even without charging consumers;
2. network effects and data advantages can constitute barriers to entry;
3. self-preferencing can raise competition concerns;
4. tying and leveraging across digital ecosystems can foreclose competitors;
5. exclusionary access restrictions can constitute abuse of dominance;
6. interoperability and data portability can become competition remedies;
7. mergers involving nascent digital competitors require closer scrutiny;
8. algorithmic conduct can facilitate coordination or exclusion;
9. app-store and digital-payment restrictions can attract antitrust scrutiny;
10. competition authorities increasingly cooperate across borders.

The convergence is not complete harmonisation. Different jurisdictions continue to disagree about the objectives of competition law, the treatment of privacy, the role of structural presumptions, merger thresholds, remedies and the appropriate balance between ex-ante regulation and traditional antitrust enforcement.

1. Meaning of Global Convergence

Global convergence does not mean that every country has identical legislation.

Instead, it means that different legal systems increasingly identify similar competitive risks and develop functionally similar responses.

For example, the EU may approach a platform through Article 102 TFEU, the UK through the Competition Act 1998 and Digital Markets, Competition and Consumers Act 2024, the United States through Sherman Act §2, India through the Competition Act 2002, and Australia through the Competition and Consumer Act 2010.

The statutory provisions differ, but authorities may nevertheless ask similar questions:

Does a powerful digital intermediary use its position to disadvantage competing businesses or protect its own ecosystem?

This functional similarity represents the core of global digital competition convergence.

2. Why Digital Markets Encourage Regulatory Convergence

A. Global Platforms Operate Across Jurisdictions

Large technology companies generally operate simultaneously in numerous countries.

A conduct decision affecting:

• search rankings,
• app-store rules,
• advertising,
• cloud access,
• data collection,
• marketplace ranking,
• payment systems,

can therefore have consequences across multiple jurisdictions.

This creates incentives for authorities to develop compatible approaches.

B. Digital Markets Have Similar Economic Characteristics

Many digital markets share common characteristics:

• network effects;
• economies of scale;
• multi-sided platforms;
• data accumulation;
• switching costs;
• interoperability dependence;
• ecosystem effects;
• zero-price services;
• algorithmic decision-making;
• high fixed costs and low marginal costs.

Consequently, competition authorities around the world increasingly encounter similar theories of harm.

3. Convergence Around Market Power

Traditional competition law frequently relied upon market shares and price-based analysis.

Digital markets require broader indicators.

Authorities increasingly examine:

1. Network effects

The value of a platform may increase as more users join it.

2. Data advantages

A platform may accumulate data that improves:

• search results;
• advertising;
• recommendations;
• fraud detection;
• artificial intelligence;
• pricing;
• targeting.

3. Switching costs

Users may face significant costs when moving:

• data;
• contacts;
• applications;
• business relationships;
• reputation;
• digital history.

4. Ecosystem power

A firm may leverage dominance in one market into another related market.

5. Access to infrastructure

Control over:

• operating systems;
• app stores;
• cloud infrastructure;
• APIs;
• payment systems;
• advertising exchanges;

may provide strategic market power.

This represents an important area of global convergence.

4. Convergence on Self-Preferencing

One of the most important developments is the treatment of self-preferencing.

A vertically integrated platform may operate both:

1. the infrastructure through which competitors reach consumers; and
2. its own competing service.

The platform may then give preferential treatment to its own products.

Examples include:

• ranking its own products first;
• displaying its own services more prominently;
• restricting competitors' access to data;
• applying different technical standards;
• imposing discriminatory terms.

The EU's Google Shopping litigation became particularly influential because it demonstrated how preferential treatment by a dominant search platform could be analysed as an exclusionary abuse.

The reasoning has influenced broader international debate over platform neutrality.

5. Convergence on Data as a Competitive Asset

Data is increasingly treated as a potential source of competitive advantage.

Competition authorities may examine whether a dominant firm:

• accumulates unique datasets;
• restricts competitors' access to data;
• combines datasets across services;
• prevents portability;
• uses data obtained from business customers to compete against them.

The important conceptual development is that data need not itself be a traditional product market to matter competitively.

Its importance can arise because it contributes to:

• entry barriers;
• economies of scope;
• algorithmic improvement;
• targeted advertising;
• customer acquisition;
• AI model performance.

6. Convergence on Interoperability

Interoperability has become increasingly important in digital competition law.

A dominant platform may control an important technical interface.

If competitors cannot interoperate effectively, the dominant firm may make switching or multi-homing difficult.

Competition authorities increasingly consider remedies such as:

• API access;
• interoperability obligations;
• technical compatibility;
• data portability;
• access to interfaces;
• non-discriminatory access conditions.

This is particularly relevant to:

• messaging;
• operating systems;
• cloud computing;
• payments;
• social networks;
• digital identity;
• connected devices.

7. Convergence on App-Store Competition

App stores have become one of the clearest examples of global regulatory convergence.

Authorities have examined:

• mandatory use of proprietary payment systems;
• commission structures;
• anti-steering restrictions;
• restrictions on alternative app stores;
• restrictions on external payment links;
• developer access conditions.

The underlying concern is similar across jurisdictions:

Can an operating-system provider use control over app distribution to restrict competition in downstream digital services?

8. Convergence on Digital Mergers

Traditional merger analysis can be inadequate where a dominant technology company acquires a relatively small emerging competitor.

The acquired firm may have:

• little current revenue;
• substantial user growth;
• valuable data;
• innovative technology;
• potential to become a major competitor.

Consequently, authorities increasingly scrutinise killer acquisitions and nascent-competitor acquisitions.

This has produced convergence around examining:

• innovation competition;
• potential competition;
• user growth;
• technological capabilities;
• datasets;
• ecosystem expansion;
• internal strategic documents.

9. Convergence on Algorithmic Competition Problems

Algorithms can create competition concerns even where traditional human coordination is difficult to establish.

Potential problems include:

Algorithmic collusion

Competitors use algorithms that facilitate parallel pricing or coordination.

Algorithmic discrimination

Algorithms selectively disadvantage particular competitors or customers.

Ranking manipulation

Platforms manipulate search or marketplace rankings.

Automated exclusion

Software automatically restricts access to competing products.

Dynamic pricing

Automated pricing systems respond rapidly to competitors' prices.

The convergence lies in recognising that technological automation does not automatically remove competition-law responsibility.

10. Major Case Laws Demonstrating Global Convergence

1. Google Search (Shopping) — European Union

Case: Google Search (Shopping) v European Commission, C-48/22 P

The case concerned Google's treatment of its comparison-shopping service in general search results.

The European Commission found that Google had systematically positioned and displayed its own comparison-shopping service more favourably while demoting competing services.

The Court of Justice ultimately upheld the central finding of abuse.

Importance

The case established a major precedent for:

• self-preferencing;
• ranking discrimination;
• platform neutrality;
• leveraging dominance;
• digital intermediation.

It has become an important reference point for global platform regulation.

2. Google Android — European Union

Case: Google and Alphabet v Commission (Google Android), C-738/20 P

The case concerned Google's contractual arrangements involving Android, including restrictions associated with:

• Google Search;
• Google Play;
• browser distribution;
• device manufacturers.

The EU institutions examined whether Google's practices strengthened its position in search and restricted competing search engines.

Importance

The case illustrates convergence around ecosystem leveraging.

Competition authorities increasingly recognise that power can be transferred between interconnected digital markets.

3. United States v Google — Search and Advertising

The United States has pursued major antitrust proceedings against Google concerning search distribution and digital advertising.

The search litigation examined Google's agreements and practices concerning distribution and default positions.

The advertising litigation concerns Google's role across multiple levels of the digital advertising technology ecosystem.

Importance

These proceedings demonstrate that the United States is increasingly addressing issues traditionally associated with European digital-platform enforcement.

This represents an important element of global convergence.

4. Epic Games v Apple — United States

Case: Epic Games, Inc. v Apple Inc., 67 F.4th 946 (9th Cir. 2023)

Epic challenged Apple's App Store restrictions, particularly Apple's rules concerning payment mechanisms and steering users toward alternative payment arrangements.

The litigation examined the competitive significance of Apple's control over iOS app distribution.

Importance

The case demonstrates the convergence of antitrust concerns around:

• app-store gatekeeping;
• payment restrictions;
• anti-steering rules;
• developer access;
• digital distribution.

Although the US legal analysis differs from EU law, the underlying competitive questions substantially overlap.

5. Epic Games v Google — United States

Case: Epic Games, Inc. v Google LLC

The litigation concerned Google's Android ecosystem and Google Play's treatment of app distribution and payment competition.

The case raised issues concerning:

• app-store power;
• distribution restrictions;
• payment systems;
• contractual arrangements;
• exclusion of rival distribution channels.

Importance

Together with the Apple litigation, it demonstrates the emergence of a globally shared competition-law problem: platform-controlled digital distribution.

6. Meta/Facebook — Germany

Case: Bundeskartellamt v Facebook/Meta, B6-22/16

The German competition authority examined Facebook's combination of user data obtained from different sources and linked this issue to Facebook's market power.

The German approach treated the interaction between:

• dominance;
• data collection;
• privacy conditions;

as potentially relevant to competition law.

Importance

This was highly influential because it demonstrated that data-processing conditions can have competition significance.

It helped promote international debate over the relationship between:

• competition law;
• privacy;
• data protection;
• platform power.

7. Facebook/WhatsApp Merger — European Union

Case: Facebook/WhatsApp, COMP/M.7217

The European Commission examined Facebook's acquisition of WhatsApp.

The investigation considered issues including:

• messaging competition;
• user data;
• network effects;
• privacy-related considerations;
• potential competition.

Importance

The case illustrated the growing importance of data and network effects in digital merger analysis.

It also helped demonstrate why digital mergers cannot always be assessed solely through traditional price effects.

8. Microsoft/Activision Blizzard — European Union

Case: Microsoft/Activision Blizzard, M.10646

The European Commission assessed Microsoft's proposed acquisition of Activision Blizzard.

The investigation examined competition in areas including:

• cloud gaming;
• gaming distribution;
• operating ecosystems;
• access to gaming content.

The transaction ultimately received conditional clearance.

Importance

This case illustrates modern merger control's increasing focus on ecosystem effects and access to digital infrastructure/content.

It also demonstrates the growing importance of behavioural remedies in digital markets.

9. Google AdSense — European Union

Case: Google AdSense, AT.40411

The Commission examined contractual restrictions that affected online advertising intermediaries.

The concern was that Google's contractual arrangements could restrict competing advertising services.

Importance

The case illustrates convergence around digital advertising intermediation as an area requiring competition-law intervention.

10. Competition Commission of India: Google Android

The Competition Commission of India examined Google's Android ecosystem and found competition concerns involving practices associated with:

• search;
• Android licensing;
• app distribution;
• payment systems;
• restrictions on manufacturers.

Importance

The Indian proceedings are particularly important because they demonstrate that digital competition principles are not limited to Europe and North America.

India has increasingly developed its own digital competition jurisprudence while addressing problems similar to those identified by the EU and other jurisdictions.

11. Comparative Convergence

12. Ex-Ante Regulation as a New Form of Convergence

One of the most significant developments is the movement from purely ex-post antitrust enforcement toward ex-ante regulation.

Traditional antitrust asks:

Has the dominant firm already engaged in unlawful conduct?

Digital regulation increasingly asks:

What rules should a systemically important platform follow before harmful conduct occurs?

Examples include:

• interoperability;
• data portability;
• anti-self-preferencing obligations;
• anti-steering rules;
• transparency;
• fair access;
• restrictions on combining datasets;
• obligations concerning app distribution.

The EU's Digital Markets Act is the strongest example of this approach, while the UK and other jurisdictions have also moved toward more specialised digital-market regulation.

13. Convergence Between Competition and Data Protection

Digital competition regulation increasingly overlaps with privacy law.

A platform may gain competitive advantage by collecting and combining enormous quantities of personal information.

Therefore, regulators increasingly consider whether:

greater data collection → stronger algorithmic performance → greater user attraction → more data → greater market power

creates a self-reinforcing competitive cycle.

This creates a regulatory triangle:

Competition law + Data protection + Digital regulation

The German Facebook litigation was particularly important in illustrating this relationship.

14. Convergence in Remedies

Digital competition cases increasingly require remedies beyond traditional fines.

Possible remedies include:

Structural remedies

• divestiture;
• separation of business units;
• prohibition of acquisitions.

Behavioural remedies

• non-discrimination;
• interoperability;
• data access;
• anti-steering;
• transparent ranking.

Technical remedies

• API access;
• portability mechanisms;
• interoperability standards;
• technical separation.

Governance remedies

• independent monitoring;
• compliance reporting;
• auditing;
• algorithmic oversight.

This represents a major transformation from conventional competition enforcement.

15. Role of International Cooperation

Digital competition enforcement increasingly involves cooperation among:

• European Commission;
• national European competition authorities;
• UK Competition and Markets Authority;
• US Department of Justice;
• US Federal Trade Commission;
• Competition Commission of India;
• Australian Competition and Consumer Commission;
• Japan Fair Trade Commission;
• other national regulators.

Cooperation helps authorities:

• exchange evidence;
• understand platform architecture;
• coordinate investigations;
• compare remedies;
• avoid contradictory outcomes;
• identify emerging competition risks.

16. Limits of Global Convergence

Despite increasing similarity, substantial differences remain.

A. Different legal standards

The EU generally places greater emphasis on preserving competitive market structures, while US antitrust has traditionally placed stronger emphasis on consumer welfare and demonstrable competitive effects.

B. Different institutional structures

Some jurisdictions rely primarily on competition authorities.

Others increasingly use:

• sector regulators;
• digital regulators;
• consumer-protection authorities;
• privacy regulators.

C. Different approaches to structural remedies

The United States may pursue structural remedies through litigation, while the EU and UK increasingly combine traditional enforcement with ex-ante digital regulation.

D. Different treatment of privacy

The relationship between privacy and competition remains particularly controversial.

Some systems treat privacy degradation as potentially relevant to competition; others are more reluctant to incorporate non-economic considerations directly into antitrust analysis.

17. The Emerging Global Digital Competition Model

The developing international model can be represented as:

Digitalisation

↓

Network effects + Data + Ecosystems

↓

Rapid concentration of market power

↓

Platform gatekeeping

↓

Self-preferencing / tying / exclusion / interoperability restrictions

↓

Competition investigation

↓

Behavioural + structural + technical remedies

↓

Continuous monitoring

This represents a shift from traditional competition law toward continuous governance of digital ecosystems.

18. Future Direction of Convergence

The next stage of global convergence is likely to focus on:

1. AI foundation models

Competition concerns surrounding control of:

• compute;
• training data;
• model distribution;
• AI chips;
• inference infrastructure.

2. Cloud computing

Particular attention to:

• switching costs;
• data egress;
• interoperability;
• cloud credits;
• vertical integration.

3. Digital advertising

Greater scrutiny of firms controlling multiple layers of the advertising stack.

4. App ecosystems

Further development of:

• alternative app stores;
• alternative payments;
• sideloading;
• interoperability.

5. Data portability

Greater recognition of portability as a competitive remedy.

6. Algorithmic coordination

Increasing investigation of AI-assisted pricing and automated coordination.

7. Digital mergers

Greater attention to acquisitions of:

• startups;
• datasets;
• AI companies;
• nascent competitors;
• infrastructure providers.

19. Overall Legal Significance

The most important feature of global convergence is that competition authorities are increasingly moving beyond the narrow question:

“Does the conduct increase prices?”

toward broader questions:

“Does the platform control an essential digital gateway?”

“Can competitors realistically enter or expand?”

“Does data accumulation reinforce market power?”

“Can users switch or multi-home?”

“Does the platform discriminate against rivals?”

“Can innovation competition be eliminated before it becomes visible in prices?”

Thus, digital competition law is increasingly concerned with market structure, contestability, innovation, access, interoperability, data and ecosystem governance.

Conclusion

Global convergence of digital competition rules represents one of the most significant developments in contemporary competition law. Although the EU, United States, UK, India, Australia, Japan and other jurisdictions retain different statutory frameworks and enforcement philosophies, they increasingly confront the same economic phenomenon: large digital ecosystems possessing network, data, infrastructure and gatekeeping power.

The major cases involving Google, Apple, Facebook/Meta, Microsoft and other technology companies demonstrate the emergence of common theories of harm concerning self-preferencing, ecosystem leveraging, app-store restrictions, data concentration, exclusionary contracts, digital advertising and nascent competition.

The future is likely to involve a hybrid system combining:

traditional antitrust + ex-ante digital regulation + data governance + interoperability + merger scrutiny + algorithmic oversight + international enforcement cooperation.

Accordingly, global convergence should not be understood as complete uniformity. It is better understood as the emergence of a shared international vocabulary and increasingly similar regulatory toolkit for controlling digital market power.
