The Rise of Tech Antitrust: What Regulators Are Planning Next

2 August 2026

For the better part of two decades, the largest technology companies operated in a climate of light-touch oversight. Regulators in the United States and Europe watched as a handful of firms consolidated control over search, advertising, mobile operating systems, app distribution, and cloud infrastructure. The prevailing theory was that consumer welfare, measured almost exclusively by price, was the only relevant yardstick. If a service was free or cheap, the reasoning went, there was no harm.

That era is over. The shift has been abrupt and consequential. Antitrust enforcement against big tech is no longer a fringe academic discussion or a European quirk. It is now a central pillar of economic policy in multiple jurisdictions. The question is no longer whether regulators will act, but how far they will go and what the practical consequences will be for businesses, developers, and consumers.

The Legal Foundations Are Being Rewritten

The traditional approach to antitrust law, particularly in the United States, has been rooted in the consumer welfare standard. Under this framework, a merger or practice is challenged only if it leads to higher prices or reduced output for consumers. This standard, heavily influenced by the Chicago School of economics, has guided enforcement since the 1980s. It worked reasonably well for traditional industries where price and output were the primary metrics of competition.

The problem is that digital markets do not behave like traditional markets. Many dominant platforms offer their core services for free. Search engines do not charge users. Social networks do not charge for basic access. Mobile operating systems are bundled with devices. The consumer welfare standard, focused on price, struggles to capture the harm in these markets. The harm is often in the form of degraded privacy, reduced choice, suppressed innovation, and the extraction of rents from businesses that depend on the platform to reach customers.

Regulators have recognized this mismatch. The Federal Trade Commission and the Department of Justice have both signaled a willingness to move beyond price-centric analysis. The FTC's 2021 lawsuit against Meta, which sought to unwind the acquisitions of Instagram and WhatsApp, was a direct challenge to the notion that a free service cannot cause competitive harm. The case was dismissed initially, but the agency refiled and the litigation continues. Regardless of the outcome, the message is clear: the old rules are being tested, and the courts are being asked to reinterpret them for the digital age.

In Europe, the shift is more advanced. The Digital Markets Act, which came into force in 2023, creates a new category of "gatekeeper" platforms. These are companies that have a significant impact on the internal market, operate a core platform service, and enjoy an entrenched and durable position. Once designated, these companies face a list of do's and don'ts that go far beyond traditional antitrust remedies. They must allow business users to access data they generate on the platform, they must allow third parties to interoperate with their services, and they cannot favor their own products over those of competitors. The penalties for non-compliance are severe, reaching up to ten percent of global turnover and twenty percent for repeat offenses.

The New Enforcement Toolkit

What makes the current wave of antitrust action different from previous efforts is the range of tools regulators are deploying. It is not just about blocking mergers or imposing fines. The new toolkit includes structural remedies, behavioral remedies, and proactive regulation.

Structural Remedies: Breaking Up Is Hard to Do

The most aggressive option is structural separation. This means forcing a company to divest a business unit or to separate its platform operations from its other commercial interests. The classic example is the breakup of AT&T in 1984, which separated the local telephone monopolies from the long-distance business. In the tech context, this could mean forcing Meta to sell Instagram and WhatsApp, or forcing Google to divest its ad-tech business.

Structural remedies are attractive because they are clean and permanent. Once a company is split, the new entities compete independently. There is no need for ongoing monitoring. However, the practical challenges are enormous. Valuing a business unit that has been deeply integrated into a parent company's infrastructure is difficult. The process of separation can take years and can be disruptive to users and employees. the courts have historically been reluctant to impose structural remedies unless there is clear evidence that behavioral remedies have failed.

The Department of Justice's case against Google over its search monopoly includes a demand for structural relief. The government has argued that Google's control over distribution channels, particularly its payments to Apple and other partners to be the default search engine, has foreclosed competition. The proposed remedy could include forcing Google to sell off parts of its advertising business or to make its search index available to rivals. The case is ongoing, and the outcome will set a major precedent for how far structural remedies can go in digital markets.

Behavioral Remedies: The Devil Is in the Details

Behavioral remedies are less drastic but more complex. They involve imposing ongoing obligations on a company to change its conduct. The European Commission has used this approach extensively in its cases against Google. In the Android case, the Commission fined Google 4.34 billion euros and required it to stop tying its search and browser apps to the Android operating system. Google was also required to offer users a choice screen for selecting their default search engine.

The problem with behavioral remedies is that they require constant monitoring and enforcement. Companies are often clever at finding ways to comply with the letter of the law while undermining its spirit. The choice screen in the Android case is a good example. Initially, Google designed the screen in a way that made it difficult for users to identify alternative search engines. The Commission had to intervene multiple times to force Google to redesign the screen. This cat-and-mouse dynamic is exhausting for regulators and can result in years of delay before consumers see any real benefit.

Proactive Regulation: The DMA and the Future

The Digital Markets Act represents a fundamental shift in philosophy. Instead of waiting for a company to abuse its position and then punishing it, the DMA imposes obligations in advance. It is a form of ex-ante regulation, similar to how utilities are regulated. The idea is that certain platforms are so important to the economy that they should be treated as essential infrastructure, subject to specific rules of the road.

The DMA is not without its critics. Some argue that it is too prescriptive and that it will stifle innovation by imposing one-size-fits-all rules on very different businesses. Others worry that the designation process is opaque and that companies will be able to game it. However, the DMA has one significant advantage: it is enforceable without the need for lengthy economic analysis in each case. The obligations are clear, and the penalties are severe. This gives the European Commission a powerful lever to force changes quickly.

The first set of designations under the DMA was announced in September 2023. Apple, Google, Meta, Amazon, Microsoft, and ByteDance were all designated as gatekeepers for various core platform services. The companies had six months to comply with the obligations. The early signs are that the Commission is serious about enforcement. It has already opened investigations into Apple and Google over their compliance plans.

The Global Landscape: A Patchwork of Approaches

One of the most important things to understand about the current moment is that there is no single global approach to tech antitrust. Different jurisdictions are pursuing different strategies, and the result is a patchwork of regulations that companies must navigate.

The European Union: The Pioneer

The EU has been the most aggressive and the most systematic. In addition to the DMA, the EU has the Digital Services Act, which imposes obligations on platforms to address illegal content and systemic risks. The EU also has a robust merger review process that has blocked or conditioned several high-profile tech deals, including the proposed acquisition of Figma by Adobe.

The EU's approach is characterized by a willingness to regulate proactively and to impose significant fines. The General Data Protection Regulation, which predates the current antitrust wave, set a precedent for the EU's willingness to impose extraterritorial rules on global companies. The DMA builds on this by creating a comprehensive framework for platform regulation.

The United States: Litigation and Legislation

The US approach is more fragmented. The federal antitrust agencies are pursuing litigation, but the process is slow and the outcomes are uncertain. The FTC has also issued a new rule banning non-compete clauses, which is not directly about tech but signals a broader willingness to use rulemaking to address market power.

At the state level, there is significant activity. Attorneys general from both parties have filed lawsuits against Google and Meta. These cases are being coordinated with the federal cases in some instances, but they can also diverge. The state cases add pressure and can result in different remedies than the federal cases.

There have also been attempts at federal legislation. The American Innovation and Choice Online Act, which would have prohibited dominant platforms from favoring their own products, came close to passing but ultimately stalled. The bill faced intense lobbying from the tech industry and opposition from some lawmakers who argued that it went too far. The likelihood of comprehensive federal legislation in the near term is low, but the issue remains on the agenda.

The United Kingdom: The New Player

The UK has carved out its own path with the Digital Markets, Competition and Consumers Act, which received royal assent in 2024. This law creates a regime similar to the DMA but with some distinct features. The Competition and Markets Authority (CMA) can designate firms with "strategic market status" and impose tailored conduct requirements. The CMA has been proactive in its investigations, particularly in areas like mobile browsers and app stores.

The UK's approach is notable for its flexibility. Unlike the DMA, which has a fixed set of obligations, the UK regime allows the CMA to design remedies on a case-by-case basis. This can be more effective in addressing specific harms, but it also introduces more uncertainty for companies.

China: A Different Model

China has taken a different approach. The State Administration for Market Regulation has been active in regulating the tech sector, but its focus has been more on data security and national security than on traditional antitrust concerns. In 2021, the SAMR imposed a fine of 18.2 billion yuan on Alibaba for anti-competitive practices, but the broader regulatory crackdown on tech companies was driven by political considerations as much as economic ones.

The Chinese approach is less predictable and more opaque than the EU or US approaches. Companies operating in China face significant regulatory risk, but the rules are not always clear. This makes it difficult for businesses to plan for the long term.

What This Means for Businesses

If you are a business that relies on a dominant platform to reach customers, the current regulatory wave is a double-edged sword. On one hand, it could open up new opportunities. If the DMA forces Apple to allow alternative app stores, for example, developers may be able to avoid the 30 percent commission. If Google is forced to make its search index available to rivals, new search engines could emerge.

On the other hand, the regulatory uncertainty is itself a cost. Companies that are designated as gatekeepers are spending significant resources on compliance. They are also changing their business models in ways that may have unintended consequences for their partners. For example, when Apple was forced to allow alternative payment systems in the Netherlands for dating apps, it introduced a new fee structure that some developers found even more onerous than the original commission.

The key takeaway for businesses is to stay informed and to be prepared for change. Do not assume that the status quo will continue. If you are a developer, start thinking about how you would operate in a world with multiple app stores. If you are an advertiser, consider what would happen if the ad-tech stack were broken up. The companies that thrive in the new environment will be those that are flexible and that have contingency plans.

Common Misconceptions

There are several misconceptions about tech antitrust that are worth addressing.

The first is that antitrust enforcement is about punishing success. This is not accurate. The goal is to protect the competitive process, not to penalize companies for being good at what they do. A company that achieves dominance through superior innovation and efficiency is not necessarily a problem. The problem arises when a company uses its dominance to exclude rivals or to entrench its position in ways that are not based on merit.

The second misconception is that breaking up big tech will automatically lead to better outcomes for consumers. This is not necessarily true. Some of the benefits of large platforms, such as network effects and economies of scale, can be lost in a breakup. A fragmented market could lead to higher prices or lower quality services. The challenge for regulators is to preserve the benefits of scale while mitigating the harms of concentration.

The third misconception is that the EU is the only jurisdiction that matters. While the EU has been the most active, the US and UK are also making significant moves. A company that complies with EU rules but ignores US or UK rules is taking a significant risk. The global nature of the tech industry means that a regulatory decision in one jurisdiction can have ripple effects everywhere.

The Road Ahead: Predictions and Recommendations

Looking forward, several trends are likely to shape the next phase of tech antitrust.

First, we will see more cases focused on artificial intelligence. The rapid advancement of AI has created new concerns about market power. Companies that control the most powerful AI models and the data needed to train them may be able to extend their dominance into new markets. Regulators are already starting to look at partnerships between AI companies and cloud providers. The Microsoft-OpenAI relationship has come under scrutiny, and the FTC has opened an inquiry into it.

Second, we will see more international cooperation. The EU, US, UK, and other jurisdictions are sharing information and coordinating their enforcement efforts. This is partly a practical matter, as the same companies are often under investigation in multiple places. But it also reflects a shared concern about the concentration of economic power in the tech sector.

Third, we will see more challenges to the business models of the largest platforms. The DMA has already forced changes to app stores, messaging services, and advertising practices. These changes are likely to accelerate as the Commission becomes more confident in its enforcement.

For businesses, the practical advice is to take the regulatory environment seriously. Do not dismiss antitrust concerns as a distant threat. The rules are changing, and the pace of change is accelerating. Consider the following steps:

- Conduct a self-assessment of your dependencies on dominant platforms. Identify where you are exposed to the risk of changes in platform policies or fees.
- Monitor regulatory developments in all the jurisdictions where you operate. The rules are not uniform, and what is legal in one place may be illegal in another.
- Build flexibility into your business model. Avoid locking yourself into a single platform or distribution channel.
- Engage with policymakers and regulators. The rulemaking process is often open to public comment, and your input can shape the outcome.

The rise of tech antitrust is not a temporary phenomenon. It is a structural shift in how the economy is governed. The companies that recognize this and adapt will be better positioned to thrive. The companies that ignore it will find themselves at a significant disadvantage.
