Antitrust Tech News Today: Big Tech Cases & Rulings

Active antitrust cases against Big Tech in the U.S.: 4 (Google, Meta, Apple, Amazon) · Largest antitrust fine imposed on a tech company: $2.5 decillion (Russia – symbolic) · Google’s settlement for Android app store case: $135 million · Year U.S. v. Microsoft monopoly case concluded: 2001 · EU antitrust fines on Google since 2017: €8.25 billion

Six key facts capture the scale of the moment: four active U.S. federal cases against the biggest tech platforms, combined EU fines that now exceed €11 billion, and a regulatory pipeline that continues to expand into artificial intelligence and cloud computing.

What are some current antitrust cases?

The U.S. Department of Justice and the Federal Trade Commission are currently pursuing illegal monopolization claims against four of the five largest technology companies — Google, Apple, Meta, and Amazon — in what legal scholars describe as the most aggressive wave of antitrust enforcement since the Microsoft case of the late 1990s. Meanwhile, the European Commission is advancing its own actions under both traditional competition law and the newer Digital Markets Act.

United States v. Google LLC (2023)

• Filed by the DOJ in October 2020; trial concluded in 2023; ruling issued August 2024
• Judge Amit Mehta ruled Google maintained an illegal monopoly in general search and text advertising
• Separate DOJ case over Google’s ad-tech business went to trial in September 2024
• Google has appealed the search ruling; remedies hearings are ongoing

FTC v. Meta (Facebook)

• FTC filed suit in 2020 seeking to unwind Meta’s acquisitions of Instagram (2012) and WhatsApp (2014) (American Action Forum)
• Case survived a motion to dismiss and is proceeding toward trial
• In April 2025, the European Commission fined Meta €200 million in connection with its “pay or consent” model

DOJ v. Apple

• DOJ filed suit in March 2024 alleging Apple maintains a smartphone monopoly
• Allegations include blocking competing messaging apps, limiting cloud gaming, and restricting third-party digital wallets
• In April 2025, the European Commission fined Apple €500 million for breaching the DMA’s anti-steering rules
• On 19 September 2025, the EU adopted two specification decisions requiring broad interoperability between third-party devices and iOS/iPadOS

Amazon antitrust case

• FTC sued Amazon in September 2023, alleging illegal monopolization of online marketplace and fulfillment services
• FTC Chair Lina Khan stated Amazon “illegally monopolizes the online marketplace”
• Amazon abandoned its acquisition of iRobot (Roomba) amid antitrust scrutiny
• EU investigation into Amazon Marketplace closed after Amazon offered commitments

The implication: every major digital platform is now fighting a two-front war — U.S. federal lawsuits targeting structural monopoly allegations, and European regulators wielding both competition law and the DMA. The outcomes, which could take years, will define the rules for the next era of the internet.

What are the antitrust issues with tech?

The core accusation across all four U.S. cases — and dozens of EU actions — is that the largest tech companies have built durable monopolies using a combination of default agreements, proprietary platform control, data accumulation, and strategic acquisitions. The DOJ and FTC are bringing illegal monopolization claims that share common theories of harm.

Monopoly power in search and online advertising

• Google pays Apple an estimated $20 billion annually to remain the default search engine on Safari
• Judge Mehta found these exclusive default agreements are anticompetitive barriers to entry
• Google controls roughly 90% of the general search market in the U.S.
• The EU fined Google €2.95 billion in September 2025 for abusing dominance in the advertising sector

App store dominance and developer fees

• Apple and Google charge a 30% commission on digital purchases within their app stores
• Epic Games won a partial antitrust victory against Apple in 2021 (though most rulings favored Apple)
• The EU’s DMA now requires Apple to allow alternative app stores and sideloading
• Google’s $135 million settlement covers allegations of monopolistic Android app distribution practices

Data privacy and anti-competitive data hoarding

• Accumulated user data creates a moat that competitors cannot easily replicate
• On 9 December 2025, the European Commission opened an abuse-of-dominance investigation into Google’s use of online content for AI training
• The same investigation targets Meta’s restrictions on AI providers offering products to WhatsApp users

Acquisitions and killer acquisitions

• Meta acquired Instagram for $1 billion in 2012 and WhatsApp for $19 billion in 2014
• The FTC is seeking to unwind both deals, arguing they eliminated future competitors
• Google acquired Waze in 2013 — critics say it neutralized a rival mapping service
• Amazon abandoned its $1.7 billion iRobot acquisition after EU antitrust objections

Did Google lose the antitrust case?

In one of the most consequential antitrust rulings in a generation, Judge Amit Mehta of the U.S. District Court for the District of Columbia found in August 2024 that Google had violated Section 2 of the Sherman Act by maintaining an illegal monopoly in general search and text advertising. The case represents the most significant monopolization ruling since the Microsoft case.

The ruling of August 2024

• Judge Mehta ruled Google is a monopolist and has acted to maintain its monopoly
• The court found that Google’s exclusive default agreements with Apple, Mozilla, and wireless carriers unlawfully restricted competition
• Google’s share of the general search market was deemed evidence of monopoly power
• The ruling applies specifically to search and text advertising, not to all of Google’s businesses

Remedies and proposed solutions

• The remedies phase is ongoing in 2025–2026
• Proposed remedies include ending default search payment agreements and requiring Google to share data with competitors
• The DOJ has raised the possibility of structural remedies, including a breakup of Google’s search and advertising businesses
• The EU similarly threatened structural breakup in the Google adtech matter before allowing Google to propose remedies instead

Appeals and future timeline

• Google has appealed the August 2024 decision
• The D.C. Circuit Court of Appeals is expected to hear the case in 2026
• An appeal to the U.S. Supreme Court is considered likely regardless of the circuit outcome
• A final resolution could take 3–5 more years, consistent with the average lifespan of major antitrust cases

What is the Microsoft antitrust case?

Microsoft’s antitrust history is the template that regulators are now applying to the rest of Big Tech. The landmark 2001 case established that even the most dominant software company could be checked by antitrust law — though the remedies were behavioral, not structural, and critics argue they failed to prevent Microsoft from maintaining its Windows and Office dominance for another two decades.

U.S. v. Microsoft (2001) – maintenance of monopoly

• The DOJ sued Microsoft in 1998 for tying Internet Explorer to Windows and maintaining a monopoly in PC operating systems
• The case settled in 2001 with behavioral remedies — Microsoft was required to share APIs and allow OEMs to promote competing software
• No breakup was ordered, and Microsoft retained its Windows monopoly
• The case is widely seen as the last major U.S. antitrust enforcement against a tech company until the current wave

Recent EU antitrust actions against Microsoft

• The European Commission investigated Microsoft for tying Teams to Office 365 and Microsoft 365
• In September 2025, the Commission accepted Microsoft’s unbundling and interoperability commitments
• The EU had previously fined Microsoft €500 million+ for the Teams bundling practice

Microsoft’s acquisition of Activision Blizzard

• The $68.7 billion acquisition faced scrutiny from the FTC, the UK’s CMA, and the European Commission
• The UK CMA initially blocked the deal over concerns about cloud gaming competition, then accepted revised remedies
• The FTC’s challenge was rejected by a U.S. federal judge in July 2023
• The deal closed in October 2023 with concessions including licensing Call of Duty to competitors

Why did Google agree to a $135 million settlement?

The $135 million settlement represents a class action case brought by Android users who alleged Google monopolized the distribution of Android apps through its Google Play Store. The case is separate from the DOJ’s search monopoly lawsuit and the EU’s competition actions.

Background of the lawsuit

• Consumers alleged that Google’s requirement that Android device manufacturers pre-install Google Play and route purchases through Google’s billing system suppressed competition
• The lawsuit claimed Google monopolized the Android app distribution market, leading to higher prices and fewer choices
• The case was filed in federal court and later granted class action status

Terms of the settlement

• Google agreed to pay $135 million without admitting wrongdoing
• The settlement covers claims from 2016 through 2021
• As part of the settlement, Google also agreed to make it easier for Android users to download apps from alternative app stores
• The settlement avoided a trial that could have resulted in larger damages (potentially trebled under antitrust laws)

Payouts for Android users

• Eligible Android users who paid for apps or in-app purchases through Google Play can claim money from the settlement fund
• The exact payout per claimant depends on the number of claims filed
• Class members must submit a claim form to receive compensation
• The settlement administrator is managing distribution under court supervision

The trade-off: Google avoided a trial that could have established harmful legal precedent and larger damages, while consumers receive modest compensation. But the structural issues — Google’s control over Android app distribution — remain largely unchanged, which is why regulators in Brussels and Washington continue to pursue more aggressive remedies.

Five major Big Tech cases, each at a different stage and with different potential outcomes, share one common thread: regulators on both sides of the Atlantic are challenging the fundamental business models that have made these companies dominant.

Timeline

The arc of Big Tech antitrust enforcement spans nearly three decades, from the Microsoft case of the late 1990s to the current pipeline of investigations into artificial intelligence and data practices. Six key moments define the trajectory.

• 1998–2001: U.S. v. Microsoft — DOJ sues for monopolization; settlement imposes behavioral remedies, no breakup
• 2017–2019: EU fines Google €2.42B (shopping search), €4.34B (Android), €1.49B (AdSense) — total €8.25 billion
• 2020: U.S. DOJ files antitrust lawsuit against Google over search monopoly; FTC files against Meta
• 2021–2022: FTC sues Meta to unwind Instagram/WhatsApp; EU passes Digital Markets Act; bipartisan antitrust bills introduced in Congress
• 2023–2024: DOJ sues Apple (March 2024); FTC sues Amazon (September 2023); Google trial concludes; Judge Mehta rules against Google (August 2024); EU fines Apple €500M under DMA (April 2025); EU fines Meta €200M (April 2025)
• 2025–2026: EU fines Google €2.95B in AdTech case (September 2025); EU opens AI investigations into Google and Meta (December 2025); EU opens DMA specification proceedings against Google for AI chatbot access (January 2026); remedies hearings for Google ongoing; appeals pending

The pattern: enforcement has accelerated dramatically. The 20-year gap between Microsoft and the current wave was followed by a flurry of cases in just 5 years — and the pipeline now extends into AI, cloud computing, and data access, suggesting the next decade will see even more activity.

Frequently asked questions

For the five biggest technology companies — Google, Apple, Meta, Amazon, and Microsoft — the convergence of U.S. litigation, EU regulation, and new investigations into artificial intelligence means that the business models that defined the last two decades are facing their most sustained challenge. For consumers, the implication is clear: expect changes to default search engines, app store policies, and data practices in the next few years. For investors, the choice is equally stark — either structural breakups that could unlock value in separated business units, or continued regulatory friction that raises compliance costs and limits strategic flexibility.
