EU's Digital Markets Act Faces First Major Tech Fines

Regulators target Big Tech gatekeeping practices

The European Union has launched formal enforcement proceedings against several of the world's largest technology companies under the Digital Markets Act, with potential fines reaching into the billions of euros — marking the most significant regulatory test yet of the bloc's landmark competition law. Regulators say the targeted firms have failed to meet obligations designed to prevent anticompetitive gatekeeping, and preliminary findings suggest non-compliance could trigger penalties of up to ten per cent of a company's global annual turnover.

Key Data: The Digital Markets Act allows fines of up to 10% of global annual turnover for first violations, rising to 20% for repeat offenders. The European Commission has designated six "gatekeepers" — Alphabet, Amazon, Apple, ByteDance, Meta, and Microsoft — covering 22 core platform services. According to Gartner, these six firms collectively account for more than 65% of all digital advertising and platform commerce revenue in the EU market. IDC estimates that DMA compliance costs across the designated gatekeepers could exceed €4 billion over three years.

What the Digital Markets Act Actually Does

The Digital Markets Act — commonly abbreviated as the DMA — is a piece of EU legislation that came into full force recently, targeting technology companies large enough to act as essential digital infrastructure for businesses and consumers alike. These companies are formally designated as "gatekeepers," a legal term for platforms so dominant in their sector that rivals, smaller businesses, and end users have no practical alternative but to use them.

The law imposes a set of "dos and don'ts" on gatekeepers — specific obligations and prohibitions that apply regardless of whether traditional antitrust harm can be proven in a given case. This is a deliberate departure from older competition law, which typically required regulators to demonstrate consumer harm through lengthy market investigations before acting.

Core Obligations Under the Law

Gatekeepers are required, among other things, to allow third-party software and app stores to operate on their platforms, to give business users access to data generated through their activity on the platform, to refrain from self-preferencing their own products in search rankings, and to allow users to uninstall pre-installed applications. The law also mandates interoperability — meaning rival messaging apps must eventually be able to communicate with dominant platforms — a requirement that has drawn particular scrutiny in relation to Apple's iMessage and Meta's WhatsApp, according to published Commission documentation.

Why "Gatekeeping" Matters

The term gatekeeping, in this regulatory context, refers to the power large platforms hold over who can access digital markets and on what terms. A company operating a dominant app store, for example, can set the rules under which rival apps are distributed, what fees developers must pay, and whether competing payment systems are permitted. Critics — including many smaller European software developers — have long argued that such control stifles innovation and raises costs for businesses and, ultimately, consumers. For more background on the legislative framework, see our earlier coverage of how the EU's Digital Markets Act forces Big Tech to open platforms.

The Enforcement Actions: Who Is Being Investigated

The European Commission, which serves as the executive and enforcement arm of the EU, has opened formal non-compliance investigations into several designated gatekeepers. The proceedings are at varying stages, but officials have made clear that preliminary findings in multiple cases indicate companies have not met their obligations within the stipulated timeframes.

Apple's App Store and Browser Practices

Apple faces scrutiny on multiple fronts. Investigators are examining whether the company's new fee structures — introduced as an alternative to its standard App Store commission following DMA requirements — constitute genuine compliance or represent what officials have described as a "commercially equivalent" barrier that effectively maintains existing gatekeeping conditions. The Commission has also raised concerns about Apple's browser choice screen, which the DMA requires be presented to users, and whether the implementation genuinely allows equal prominence for competing browsers. Apple has disputed the Commission's preliminary findings, according to publicly available correspondence between the company and regulators.

Alphabet and Google Search

Alphabet, the parent company of Google, is facing investigation into whether its search results continue to favour its own comparison shopping, travel, and local services products over rivals — a practice already found to be illegal under older EU competition law in proceedings that resulted in multi-billion euro fines over the past decade. Under the DMA, the standard for intervention is lower: regulators do not need to prove harm, only that a designated obligation has not been met. A separate strand of the investigation concerns Google Play, the Android app marketplace, and whether Alphabet has given rival app stores equivalent access to the Android ecosystem as originally required by the legislation. Further context is available in our report on the EU Digital Markets Act targeting Big Tech with new fines.

Meta and Advertising Data

Meta, which operates Facebook, Instagram, and WhatsApp, is under investigation for its "pay or consent" model — a scheme introduced in response to EU data protection requirements that gives users the choice between seeing personalised advertisements or paying a monthly subscription fee to use the platforms without targeted ads. Regulators have indicated this model may not constitute valid consent under either data protection or competition law frameworks, and that it may amount to a form of tying that the DMA is designed to prohibit. A final determination has not been issued, officials said.

Scale of Potential Penalties

The financial stakes are substantial. Under DMA rules, a first violation can trigger a fine of up to ten per cent of a company's total global annual turnover — not merely EU revenue. For companies such as Alphabet and Apple, which each report annual revenues well in excess of $300 billion, this would represent fines potentially in the range of $30 billion or more, though regulators typically calibrate penalties to the severity and duration of the infringement rather than applying maximum rates automatically.

Repeat violations carry penalties of up to twenty per cent of global turnover, and in cases of systematic non-compliance the Commission retains the power to impose behavioural or structural remedies — including, in extreme cases, requiring a company to divest business units operating within the EU. According to Wired's analysis of the DMA enforcement mechanism, no equivalent digital market law anywhere in the world carries comparable financial exposure for platform companies.

Industry Response and Legal Challenges

Technology companies subject to DMA obligations have not accepted the Commission's preliminary findings without challenge. Several firms have filed procedural objections and requested oral hearings — standard steps in EU administrative proceedings that allow companies to contest findings before a final decision is issued.

Arguments from the Gatekeepers

The companies under investigation have collectively argued, in public statements and regulatory filings, that compliance measures they have introduced are genuine and proportionate, that the Commission's interpretation of certain obligations is broader than the legislation permits, and that some requirements — particularly around interoperability — create security vulnerabilities for end users. Apple has been particularly vocal in arguing that opening iOS to third-party app stores increases the risk of malware distribution, a claim regulators and independent security researchers have disputed in published responses.

The Judicial Route

Any final Commission decision imposing a fine can be appealed to the EU General Court and, subsequently, to the Court of Justice of the European Union. These proceedings typically take years to resolve, meaning the most significant financial penalties may not be definitively confirmed for some time. However, Commission decisions are generally enforceable pending appeal unless a court grants an interim suspension — which is rarely done in competition cases, according to established EU legal practice as documented by the Commission itself.

Implications for the UK and Global Regulation

The DMA's enforcement trajectory is being watched closely by regulators and legislators in the United Kingdom, the United States, Australia, Japan, and South Korea — all of which have enacted or are developing similar platform competition legislation. The UK's own framework, developed separately following Brexit, shares many philosophical underpinnings with the DMA but differs in its procedural approach, relying more heavily on case-by-case investigation by the Competition and Markets Authority rather than upfront categorical obligations. Our coverage of the UK Digital Markets Bill facing its final parliamentary vote details how Westminster has approached similar concerns.

According to MIT Technology Review's analysis of global platform regulation, the EU's willingness to pursue fines under the DMA will act as a signal to other jurisdictions about whether such laws can be enforced effectively against companies with significant legal and lobbying resources. A pattern of protracted negotiation and minimal penalties would, analysts note, undermine the credibility of similar regimes elsewhere.

Regulatory Coordination

The European Commission has established working relationships with competition authorities in EU member states, and national regulators in Germany, the Netherlands, and France — which have their own platform-specific rules — are understood to be coordinating with Brussels on overlapping investigations. This layered enforcement structure increases compliance pressure on gatekeepers, since a company might face simultaneous proceedings at both EU and national level for related conduct, officials said.

What Comes Next

The Commission is expected to issue formal non-compliance decisions in at least two of the active investigations within the coming months, according to officials familiar with the proceedings. These decisions would set out findings of fact, the legal basis for the determination, and the proposed financial penalty — at which point the affected company would have a defined period to pay or initiate an appeal.

The DMA's enforcement phase is arriving simultaneously with the early implementation of the EU's AI Act, which establishes separate but related obligations for artificial intelligence systems deployed by large technology platforms. Observers note that the combined regulatory burden represents the most demanding compliance environment large technology companies have ever faced in a single jurisdiction. Readers following the intersection of these regimes may wish to review our reporting on how the EU's AI Act enforcement begins with first major tech fines, as well as the broader legislative picture covered in our analysis of the EU finalizing AI Act rules for major tech firms.

Company	DMA Designation	Primary Area Under Investigation	Maximum Fine Exposure (Est.)	Current Status
Apple	Gatekeeper (iOS, App Store, Safari)	App Store fee structures, browser choice screen	Up to 10% global turnover	Formal proceedings open
Alphabet (Google)	Gatekeeper (Search, Play, Maps, Chrome)	Search self-preferencing, Play Store access	Up to 10% global turnover	Preliminary findings issued
Meta	Gatekeeper (Facebook, Instagram, WhatsApp)	"Pay or consent" advertising model	Up to 10% global turnover	Investigation ongoing
Amazon	Gatekeeper (Amazon Marketplace)	Self-preferencing of Amazon products in listings	Up to 10% global turnover	Under review
Microsoft	Gatekeeper (Windows, LinkedIn, Teams)	Teams bundling with Office 365	Up to 10% global turnover	Monitoring phase
ByteDance	Gatekeeper (TikTok)	Data access obligations, advertising transparency	Up to 10% global turnover	Under review

The first DMA fines — whenever they arrive — will be as much a statement of political and regulatory intent as a financial measure. The scale of the enforcement apparatus the Commission has assembled, and the breadth of the obligations it has imposed, represent a generational shift in how democratic governments are choosing to manage the market power of the world's largest technology platforms. Whether the penalties prove large enough, and the proceedings swift enough, to meaningfully alter corporate behaviour remains the central question that regulators, businesses, and consumers across the continent are now waiting to see answered.
