Most of Europe’s apps and company systems run on a few US clouds.

EU · 2024– · ongoing · 9 min

Europe's Digital Markets Act tells the biggest tech platforms—gatekeepers like Apple and Google—what they must do up front: choice screens, alternative app stores, fair messaging links, and more. Early compliance updates drew complaints that new fees and scary pop-ups discourage real competition. EU regulators opened investigations, but no final penalties have been decided—this is an ongoing regulatory story, not a finished court case.

Outcome: The Commission has issued DMA non-compliance decisions, including Apple's €500 million steering fine and Meta's €200 million pay-or-consent fine in April 2025. On 8 July 2026 the General Court dismissed Apple's challenge to its App Store and iOS gatekeeper designation. Other DMA files remain open.

The Justice Department's Live Nation case is in a proposed 2026 settlement that a judge had not finished reviewing by early October. States that refused the deal won a jury verdict and are still in court. The proposed federal deal is not a Ticketmaster breakup.

Outcome: A term sheet was signed on 5 March 2026. On 12 June 2026 the Justice Department and six states filed a proposed final judgment; the court entered the stipulation on 15 June. Public comments closed 4 September 2026, so Tunney Act review was not finished as of early October. Other states refused the deal, tried the case, and a jury found liability on the major claims. Those state claims are still open.

Big Tech funded AI startups through partnerships instead of classic mergers. The FTC wants to know whether those deals secretly block competition for chips, data, and engineers. This is an inquiry—a fact-finding step—not a ruling that AI partnerships are illegal.

Outcome: On 30 June 2025 Judge Julien Neals denied Apple's motion to dismiss and rejected a worldwide market definition. The case is in discovery. Bloomberg reported early settlement talks in July 2026. No deal had been announced by early October 2026, and no trial date was set.

Apple is still in court over how far it must open iOS to rivals under Europe's Digital Markets Act. The fight is about specification decisions, not about whether Apple is a gatekeeper — that designation challenge failed in July 2026.

Outcome: Apple's appeals of specification proceedings DMA.100203 and DMA.100204 were still pending as of September 2026. A published account of the docket said one per-feature deadline remains 1 June 2027. The General Court separately dismissed Apple's challenge to its gatekeeper designation on 8 July 2026.

US · 2023– · ongoing · 10 min

The US Federal Trade Commission says Amazon uses its dominance in online shopping to hurt sellers and shoppers—for example, by punishing merchants who offer lower prices on other websites and by favoring Amazon's own products in search. Amazon calls the lawsuit wrong on the facts and the law. The case is still in early litigation, so treat claims as allegations.

Outcome: Judge Chun denied Amazon's motion to dismiss in April 2025. A December 2025 schedule set expert discovery in 2026 and a bench trial for 29 March 2027. A related District of Columbia case is on its own pretrial track. No judgment on the monopoly claims.

Rent went up in many US cities—and prosecutors say one reason is software. RealPage's tool allegedly lets big landlords share secret pricing data and follow the same algorithm's suggestions, acting like a price-fixing cartel without a smoke-filled room. DOJ, states, and tenants sued. Landlords and RealPage deny wrongdoing. No court has ruled yet.

Outcome: The DOJ reached proposed resolutions with RealPage, Cortland, Greystar, LivCor, Willow Bridge (July 6, 2026), and Pinnacle (September 4, 2026). Those decrees bind the Justice Department's claims only. On October 1, 2026 the court denied motions to dismiss the plaintiff states' claims against RealPage, Pinnacle, Camden, and Willow Bridge and said those claims are not mooted by the DOJ decrees. Unless the states settle, that part of the case moves toward trial.

UnitedHealth–Change review

US · 2022– · ongoing · 10 min

UnitedHealth bought Change Healthcare—a company that processes huge shares of US medical claims—after beating a DOJ block attempt. A massive 2024 cyberattack on Change froze pharmacies and clinics, sparking new outrage about one company owning both insurance and critical health data pipes. Congress is investigating; no court has ordered a breakup.

Outcome: Merger closed after 2022 litigation loss for DOJ; post-attack reviews, hearings, and private litigation strands ongoing—no retroactive breakup ordered.

EU DMA Gatekeepers

EU · 2022– · ongoing · 10 min

Europe's Digital Markets Act treats the biggest tech platforms like regulated utilities: they must open doors they used to lock. Apple, Google, Meta, Amazon, Microsoft, and others must offer more choice in app stores, messaging, search defaults, and data sharing. Regulators are still checking whether the changes work—or whether companies comply only on the surface.

Outcome: Designations and core obligations are in force; compliance dialogues, DMA Article 29 market investigations, and potential fines remain active. No final closure of oversight.

The FTC sued the three largest pharmacy benefit managers over insulin rebates. Express Scripts settled in February 2026 and Caremark in July 2026. Optum's proposed consent still needed Commission approval, so the docket was still pending.

Outcome: FTC docket 9437 was still listed as pending in July 2026. Express Scripts' settlement was announced February 4, 2026, and Caremark's on July 14, 2026. The Optum portion was withdrawn from adjudication for a proposed consent that the Commission had not finally approved. This file stays live until that last consent is finished.

Most imported goods ride in containers on ships operated by a handful of global carriers that legally cooperate in alliances. After pandemic price spikes, US agencies asked whether those alliances act too much like cartels. Investigations and FMC oversight continue; alliances still operate.

Outcome: Congress adjusted FMC authority; antitrust agencies monitor alliance filings; no US court has dismantled a major alliance yet.

Hotels often sell rooms through Booking.com and Expedia, which once forbade lower prices on hotel websites. Europe banned the worst parity clauses, but regulators still check whether platforms punish hotels that offer cheaper direct deals. Reviews continue country by country.

Outcome: National parity bans and EU-wide dialogues continue; Commission and NCAs monitor compliance without a single EU-wide fine closing the matter.

Restaurants pay delivery apps hefty commissions on every order. European regulators are checking whether platforms abuse power by pushing ads, hiding ranking rules, or favoring their own ghost kitchens. National fee caps appeared; EU antitrust cases continue without a final continent-wide verdict.

Outcome: Spanish and other national measures capped fees temporarily; abuse investigations and DMA-style transparency debates continue without EU-wide final penalties.

The appeals were not a final Supreme Court end-point that wiped the file out. Treat the Indian docket as open until that court says otherwise.

Outcome: The case remained in pretrial in 2026. Parties in the related FTC action told the Seattle court that D.C.'s trial calendar, discussed around May 2027, had to be coordinated with the FTC bench trial set for 29 March 2027. No judgment.

Europe fined Google about €2.95 billion in 2025 over ad tech. Google contests EU antitrust fines as a matter of course. The American case ended its remedy phase in September 2026 without forcing a sale of the ad exchange.

Outcome: A 2025 Commission fine of about €2.95 billion is on the public record. Google's practice in EU antitrust cases is to appeal, and this fine should be treated as contested until the General Court rules. The US court, separately, rejected an AdX divestiture on 2 September 2026.

The US government sued Google over search defaults—the box most people use to find things online. A court found Google broke the law in 2024. The September 2025 remedy order curbs exclusive default deals but does not spin off Chrome or Android.

Outcome: Judge Mehta found liability in August 2024 and, in a September 2025 order, barred exclusive default deals and required data-sharing. He refused to order a Chrome or Android sale. Google appealed to the D.C. Circuit in January 2026; the Justice Department and states cross-appealed. On May 7, 2026 he denied, without prejudice, Google's request for a partial stay. The cross-appeals were still pending in October 2026.

Spotify and other music apps compete with Apple Music but must use Apple's App Store to reach iPhone users. Europe says Apple used its control of that store to block apps from telling you about cheaper prices on the web and to favor its own music service. Apple was fined, but arguments over App Store changes are still playing out.

Outcome: Commission fined Apple €1.84 billion in 2024 for music streaming-related abuses; DMA gatekeeper obligations and compliance monitoring continue.

Big airlines team up on international routes through 'joint ventures' that share money and schedules—sometimes with government permission that shields them from antitrust suits. US enforcers keep reviewing whether those deals reduce competition and raise fares. The Northeast Alliance was blocked, but many immunized alliances still fly.

Outcome: Periodic reviews, sunset conditions, and informational demands ongoing; no blanket dissolution order publicly issued in current review cycles.

Outcome: Jury verdict for Epic in December 2023. A three-year injunction requires rival stores and catalog access. The Ninth Circuit affirmed in July 2025. The Supreme Court denied a stay in October 2025. A further stay request and settlement talk were reported into 2026. The injunction fight is not over.

Europe fined Meta about €798 million in November 2024 for tying Facebook Marketplace to the social network. Meta is challenging that fine, so the antitrust case is still live. A separate DMA label on Marketplace was annulled by the General Court on 3 June 2026.

Outcome: The November 2024 tying decision is under challenge. Separately, the Commission repealed Marketplace's DMA gatekeeper label in April 2025, and on 3 June 2026 the General Court annulled that designation while leaving Messenger's designation in place.

The war isn't over, but EU regulators have scored one major win.

Outcome: March 2024 infringement decision imposed €1.84B fine on Apple for music streaming steering; Apple appealed. Spotify pursues further DMA fee challenges—overall dispute not fully closed.
