The DOJ's Apple Antitrust Case Just Cleared Its Biggest Hurdle. The Walled Garden Is the Theory.

  • 88 pagesLength of the complaint filed in U.S. District Court, D.N.J., Case 2:24-cv-04055. Alleges five categories of monopolistic conduct: super apps, cloud streaming games, messaging, smartwatches, and digital wallets.
  • 65–70%Apple's U.S. smartphone market share per the DOJ complaint — and 70%+ in the premium segment. DOJ cites the 1998–2001 U.S. v. Microsoft case (Microsoft had 90%+ PC OS share) as the legal template.
  • DeniedApple's motion to dismiss, denied by U.S. District Judge Julien Xavier Neals on June 30, 2025. Case proceeds to discovery; no trial date publicly set as of May 2026.

On March 21, 2024, the U.S. Department of Justice and a bipartisan coalition of 16 state attorneys general filed an 88-page antitrust complaint against Apple Inc. in the U.S. District Court for the District of New Jersey, case number 2:24-cv-04055. The named officials at the press conference were Attorney General Merrick Garland (D), Deputy AG Lisa Monaco (D), and Assistant Attorney General for Antitrust Jonathan Kanter (D). Apple shares dropped roughly 4 percent intraday; market capitalization fell by approximately $113,000,000,000 by close.

The complaint's theory is the “walled garden”: that Apple has used contractual restrictions, technical restrictions, and selective API access to lock users into the iPhone ecosystem and to lock competitors out of five specific markets — super apps, cloud streaming games, messaging, smartwatches, and digital wallets. DOJ cites the 1998–2001 U.S. v. Microsoft case as the legal template. Apple CEO Tim Cook called the case “misguided” in a May 2024 CNBC interview and vowed to fight it.

On June 30, 2025, U.S. District Judge Julien Xavier Nealsdenied Apple's motion to dismiss, ruling that DOJ had “sufficiently pled” monopoly power in U.S. smartphone and high-end-performance segments. The case is now in discovery. No trial date has been publicly reported. Twenty states are now co-plaintiffs — 15 Democratic AGs, 5 Republican AGs, including Republican AGs in New Hampshire, North Dakota, Oklahoma, Tennessee, and Indiana.

§ 01 / The Filing — Case 2:24-cv-04055

The complaint runs 88 pages and identifies five categories of allegedly monopolistic conduct. Under super apps, DOJ argues Apple has suppressed third-party super-app development that would let users switch phones without losing functionality. Under cloud streaming games, the complaint alleges Apple blocked cloud-gaming providers from offering subscription streaming through the App Store. Under messaging, DOJ targets Apple's differential treatment of iMessage vs. SMS — the so-called “green bubbles” problem — as a switching-cost lock-in. Under smartwatches, DOJ alleges Apple Watch's deep iOS integration is unavailable to competing watchmakers. Under digital wallets, the complaint argues Apple Pay's exclusivity on NFC payments locks out competing wallet providers from the iPhone's payment hardware.

The complaint quotes internal Apple emails and Tim Cook's own public statements to argue that the suppressive behaviors are intentional, not incidental to product design. DOJ's requested remedies were left open at filing — Bloomberg reported on March 20, 2024, the day before filing, that a DOJ official did not rule out structural divestiture as a remedy if the government prevails. That is the Microsoft 2001 template.

Apple has maintained monopoly power in the smartphone market not simply by staying ahead of the competition on the merits, but by violating federal antitrust law.

§ 02 / The Antitrust Theory — Microsoft as Template

Asst. AG Kanter framed the case explicitly against the 2001 U.S. v. Microsoftprecedent at the filing-day press conference. His argument: that case “paved the way for Apple to launch iTunes, iPod and eventually the iPhone” — and this new case is structured to protect the next generation of competition from being suppressed before it launches.

Microsoft, when it was sued in 1998, had a documented 90%+ share of the global PC operating-system market. Apple's U.S. smartphone share per the complaint is 65 to 70 percent, with 70%+ in the premium segment — lower than Microsoft's peak. Apple has pointed to its ~20 percent global smartphone share as evidence the case is misdirected. The legal question is whether the U.S.-specific premium segment is the right market definition. DOJ argues it is. The June 30, 2025 ruling indicates the court agrees that DOJ has at minimum stated a plausible market.

Apple has gone from revolutionizing the smartphone market to smothering it.

§ 03 / The Market Reaction

Apple closed down approximately 4 percent on March 21, 2024. About $113,000,000,000 in market capitalization was erased that day — roughly a year of Apple R&D spending. The next session, Apple recovered about $15,000,000,000 as analysts absorbed the case's structure and noted the years of litigation ahead. Apple's 2023 net revenue was $383,000,000,000; net income was $97,000,000,000.

App Store revenue, per analyst estimates cited by Fortune, was approximately $27,000,000,000 in 2023. That figure is an estimate — the complaint itself does not cite a specific App Store commission revenue number — but it is the financial line that would face the most direct structural pressure if the government prevails on the payments-and-distribution theories.

Bipartisan State AG Coalition

15 Democratic + 5 Republican state attorneys general are now co-plaintiffs on a case that the press routinely frames as a Biden-DOJ initiative. The Republican AGs are John Formella (R-NH), Drew Wrigley (R-ND), Gentner Drummond (R-OK), Jonathan Skrmetti (R-TN), and Todd Rokita (R-IN). The Democratic AGs include Kris Mayes (D-AZ), Rob Bonta (D-CA), Letitia James (D-NY), and Keith Ellison (D-MN)— with Massachusetts AG Andrea Campbell (D-MA), Nevada AG Aaron Ford (D-NV), and Washington AG Bob Ferguson (D-WA) joining at the June 11, 2024 expansion. Big Tech antitrust is one of the few areas of bipartisan AG cooperation in the current political moment.

U.S. Department of Justice
@TheJusticeDept · March 21, 2024· paraphrase

Today, the Justice Department, joined by 16 state and district attorneys general, filed a civil antitrust lawsuit against Apple for monopolizing smartphone markets.

§ 04 / Apple's Defense

Apple's public response was issued the morning of filing and Tim Cook elaborated it publicly six weeks later in a CNBC interview. The company's argument is twofold. First: global market share. Apple is at roughly 20 percent of global smartphone shipments — well below historical monopolization thresholds, and the case's reliance on the premium U.S. segment is, in Apple's framing, a gerrymandered market definition. Second: product-design authority. Cook framed the DOJ's remedy ambitions as an attempt to use the law to dictate how Apple designs its products — specifically pointing at iMessage, the App Store review process, and the privacy / security justifications for those choices.

I think the case is misguided, and we're going to fight it. It's my job to make sure it doesn't become a distraction. If you look at what they're trying to do, is essentially use the law to define how we design products. And that shouldn't be like that.

Apple CEO Tim Cook · CNBC interview · May 2, 2024

On August 1, 2024 Apple filed its formal motion to dismiss, arguing that DOJ had not pled a viable market definition and that the conduct described in the complaint reflected lawful product-design choices protected by intellectual-property and free-contract law. The motion-to-dismiss filing was 89 pages. The DOJ's opposition brief and the state coalition's response added another 200+ pages to the docket. Judge Neals heard oral argument in March 2025.

Donald Trump@realDonaldTrump · Truth Social

Big Tech has run wild for years, stifling competition in our most innovative sector and, as we all know, using its market power to crack down on the rights of so many Americans, as well as those of Little Tech.

Trump on Big Tech antitrust enforcement — documented public position. Did not specifically defend Apple in the DOJ case; nominated Gail Slater as AAG for Antitrust in December 2024, signaling the case would continue under the second-term administration.

§ 05 / Where the Case Stands as of May 23, 2026

Judge Neals' June 30, 2025 ruling denied Apple's motion to dismiss in full. The court held that DOJ had adequately pled both monopoly power and exclusionary conduct in two relevant antitrust markets. Discovery is now underway. Apple must produce internal communications and design documentation responsive to DOJ's subpoenas. Apple's counterclaims for sanctions over allegedly overbroad subpoenas are pending. No trial date is set; comparable antitrust cases of this scale (Microsoft, Google Search, Meta) have taken three to four years from filing to first-instance verdict, so a 2027 or 2028 trial is the realistic window.

One signal worth tracking: the Trump administration did not drop the case after taking office in January 2025. President Trump nominated Gail Slater (R)as Assistant Attorney General for Antitrust — a documented Big Tech critic. Under Slater, DOJ continued to oppose Apple's motion to dismiss with the same arguments the Biden DOJ had advanced. That is the cleanest signal of bipartisan executive-branch commitment to the case theory: two administrations of opposite parties, same DOJ position on whether Apple's walled garden constitutes illegal monopolization.

For readers: the antitrust apparatus is one of the few federal-government functions where Democratic and Republican DOJs have, over the last decade, moved in the same direction on Big Tech. The Microsoft case (1998), the Google Search monopoly case (2020, Trump 1), the Google Ad Tech case (2023, Biden), and now the Apple case (2024, Biden → continued under Trump 2) form a single throughline. The walled garden is the legal theory at issue here. The question of remedy — behavioral, structural, or none — is the next chapter, and it will be written by Judge Neals in the U.S. District Court for the District of New Jersey.

The Bottom Line

The DOJ's Apple antitrust case survived its biggest procedural test on June 30, 2025. The five-theory walled- garden complaint is now on the discovery clock. A bipartisan 20-state AG coalition is co-plaintiff. Two administrations of opposite parties have kept DOJ's position consistent. The remedy question — including whether structural divestiture is on the table — gets answered at trial, likely in 2027 or 2028.
