Five years after a Fortnite character was booted from the iPhone, the legal war between Apple Inc. and Epic Games is heading back to the highest court in the land. What started as a dispute over a 30% commission on in-app purchases has metastasized into something far larger: a constitutional question about how much power courts have to reshape the business models of America’s most valuable companies.
Apple is preparing to ask the U.S. Supreme Court to review a Ninth Circuit ruling that found the company violated California’s Unfair Competition Law by prohibiting app developers from steering users to cheaper payment options outside the App Store. The petition, expected in the coming weeks, will mark the second time this case has reached the Supreme Court’s doorstep — and this round carries consequences that extend well beyond mobile gaming.
The Anti-Steering Injunction That Changed Everything
To understand why Apple is fighting this hard, you have to go back to the original trial. In September 2021, Judge Yvonne Gonzalez Rogers of the U.S. District Court for the Northern District of California issued a mixed ruling. She found that Apple was not a monopolist under federal antitrust law — a significant win for the company. But she also found that Apple’s anti-steering provisions, which barred developers from telling users about alternative payment methods, violated California’s UCL. She issued an injunction requiring Apple to let developers include links and information directing customers to non-App Store purchasing mechanisms.
Apple appealed. Epic cross-appealed. The Ninth Circuit, in April 2023, largely upheld the district court’s findings, affirming that Apple wasn’t a monopolist but agreeing that the anti-steering rules were anticompetitive under state law. The Supreme Court declined to hear Epic’s petition on the federal antitrust questions in early 2025. But the anti-steering injunction — and Apple’s challenge to it — remained very much alive.
As 9to5Mac reported, Apple is now gearing up for another Supreme Court petition, this time targeting the injunction itself and the legal framework that produced it. The company’s core argument is that the Ninth Circuit applied the wrong standard when it evaluated the anti-steering provisions under California’s UCL, and that the resulting injunction amounts to a federal court rewriting Apple’s contracts with millions of developers worldwide.
The stakes are enormous. Not just for Apple, which generates an estimated $20 billion or more annually from App Store commissions. For every platform company that imposes conditions on how third parties interact with customers.
Apple’s legal team, led by outside counsel at Gibson Dunn, has signaled in lower court filings that the case raises questions of national importance. Among them: whether a state unfair competition statute can be used to impose what amounts to a federal antitrust remedy when the plaintiff has already lost on federal antitrust grounds. It’s a sharp argument, and one designed to appeal to a Supreme Court that has shown increasing skepticism toward expansive lower court injunctions.
Epic Games CEO Tim Sweeney has been characteristically vocal. In recent posts on X, Sweeney has framed the fight as one about developer freedom and consumer choice, arguing that Apple’s commission structure amounts to a tax on digital commerce that wouldn’t be tolerated in any other industry. “Apple charges 30% on all digital goods and blocks companies from even telling customers they can pay less elsewhere,” Sweeney posted in March 2026. “That’s not competition. That’s control.”
He’s not wrong about the economics. But whether that control is illegal is precisely what the courts have struggled to determine.
A Regulatory Pileup on Multiple Continents
Apple’s Supreme Court strategy doesn’t exist in a vacuum. The company is simultaneously fighting regulatory actions in the European Union, Japan, South Korea, and the United Kingdom — all of which target the same basic business practice: Apple’s control over how apps are distributed and how payments are processed on its devices.
The EU’s Digital Markets Act, which took effect in March 2024, required Apple to allow alternative app stores and payment systems on iPhones sold in Europe. Apple complied, technically, but imposed a new fee structure that critics — including Sweeney and Spotify CEO Daniel Ek — called deliberately punitive. The European Commission opened a non-compliance investigation, and as of early 2026, that investigation remains ongoing.
In Japan, new legislation effective this year requires Apple to permit third-party payment processing in apps. South Korea passed similar rules in 2021, though enforcement has been uneven. And in the U.K., the Competition and Markets Authority has been conducting a mobile browser and cloud gaming market study that touches directly on Apple’s platform restrictions.
Each of these regulatory actions chips away at the same model Apple is defending in the U.S. courts. And each one makes the Supreme Court case more consequential, because a definitive ruling from the highest American court would set a benchmark — or at least a reference point — for regulators worldwide.
The timing matters for another reason. The U.S. Department of Justice filed its own antitrust lawsuit against Apple in March 2024, targeting a broader set of practices than Epic’s case but raising many of the same themes. That case, United States v. Apple Inc., is in its early stages in the District of New Jersey. A Supreme Court ruling on the scope of permissible anti-steering provisions could shape how the DOJ case unfolds.
So Apple is fighting on at least five fronts simultaneously. That’s expensive, even for a company with $162 billion in cash on hand.
But the cost of losing may be higher. Morgan Stanley analysts estimated in a January 2026 note that if Apple were forced to allow unrestricted third-party payment processing globally, the impact to services revenue could reach $8 to $12 billion annually. Services — the segment that includes App Store commissions, Apple Music, iCloud, and AppleCare — has been Apple’s fastest-growing business and its highest-margin division. Wall Street has rewarded the company’s services narrative with a premium multiple. Anything that threatens that narrative threatens the stock.
Apple knows this. It’s why the company has fought every legal and regulatory challenge with the full weight of its resources, deploying armies of lawyers and lobbyists in Washington, Brussels, Tokyo, and Seoul.
And yet the ground keeps shifting beneath them.
The original Epic v. Apple trial produced a factual record that has proven remarkably durable. Judge Gonzalez Rogers’s 185-page opinion documented internal Apple communications showing that executives were aware the 30% commission was higher than what a competitive market might sustain, but maintained it because the closed nature of iOS gave them the power to do so. One particularly damaging email, from an Apple executive discussing the commission rate, noted that “ichigan doesn’t have a competitive alternative” — a reference to the lack of sideloading options on iPhone.
That factual record has been cited in regulatory proceedings around the world. It has become, in effect, the evidentiary foundation for a global assault on Apple’s business model.
Epic, for its part, hasn’t exactly been passive. The company launched the Epic Games Store on iOS in the EU in 2024, taking advantage of the DMA’s requirements. It has also continued to invest in its PC game store, which takes only a 12% commission — a deliberate contrast with Apple’s 30% (or 15% for small developers under Apple’s reduced rate program). Sweeney has positioned Epic as the champion of an open platform future, even as critics point out that the company’s own store on PC lacks many features that Steam, its primary competitor, offers.
The philosophical divide here is real. Apple argues that its integrated model — hardware, software, and services tightly controlled by one company — is what makes the iPhone secure, reliable, and valuable. Opening the platform to third-party payment processors and app stores, Apple contends, would expose users to fraud, malware, and a degraded experience. There’s some truth to this. The Android platform, which allows sideloading and alternative app stores, does have higher rates of malware infection.
But critics counter that Apple’s security arguments are pretextual — a convenient justification for what is fundamentally an economic arrangement designed to extract rents from developers. They point to the fact that Apple allows unrestricted web browsing on iPhones, where users routinely encounter phishing sites and malicious downloads, without imposing a commission. The security argument, they say, applies selectively: only where money is at stake.
What the Supreme Court Will Actually Decide
If the Supreme Court grants certiorari — and that’s a genuine if — the justices won’t be ruling on whether Apple’s 30% commission is fair or whether the App Store should be opened to competitors. The question will be narrower and more technical: whether the Ninth Circuit correctly applied California’s UCL to Apple’s anti-steering provisions, and whether the injunction requiring Apple to allow external payment links is an appropriate remedy.
Apple will argue that the UCL was never intended to serve as a backdoor antitrust statute, and that using it to impose structural changes on a company that was found not to be a monopolist under federal law creates a dangerous precedent. The company will also likely raise First Amendment concerns, arguing that being forced to facilitate third-party commercial speech within its own platform implicates its rights as a platform operator.
Epic will counter that the UCL is a broad consumer protection statute that California courts have long applied independently of federal antitrust law, and that the injunction merely requires Apple to stop suppressing truthful commercial information. The company will also argue that the Supreme Court has no reason to intervene in what is essentially a fact-bound application of state law.
Legal scholars are divided. Some, like Herbert Hovenkamp of the University of Pennsylvania, have argued that state UCL claims shouldn’t be used to circumvent federal antitrust standards. Others, like Tim Wu of Columbia, have suggested that federal antitrust law has become so permissive that state consumer protection statutes serve as a necessary check on corporate power.
The cert petition will likely be filed before the end of June 2026. If the Court takes the case, oral arguments would probably occur in the October 2026 term, with a decision by June 2027. That timeline matters because it would overlap with the DOJ’s antitrust case against Apple, potentially creating either helpful precedent or awkward contradictions.
For developers, the practical implications are already being felt. Since the Ninth Circuit’s ruling, Apple has implemented a version of the anti-steering injunction in the U.S., allowing developers to include a single link directing users to an external website for purchases. But the implementation has been criticized as minimal. Developers must use a specific Apple-approved link format, and Apple still collects a reduced commission — 27% for most developers, 12% for those in the Small Business Program — on purchases made through external links within seven days of the link being clicked.
Sweeney has called this “malicious compliance.” Apple calls it a reasonable implementation of the court’s order. Judge Gonzalez Rogers has held several hearings on compliance, and the issue remains contentious.
Meanwhile, the broader app economy watches and waits. Spotify, Match Group, and other large developers have filed amicus briefs or made public statements supporting Epic’s position. The Coalition for App Fairness, an industry group that includes Epic, Spotify, and others, has lobbied Congress for legislation that would codify many of the same principles at stake in the litigation.
Congressional action has stalled, however. The Open App Markets Act, introduced with bipartisan support in 2022, never received a floor vote. Similar bills have been reintroduced but face an uncertain path in a Congress focused on AI regulation and other technology issues.
So the courts remain the primary venue. And the Supreme Court may soon have the final word — at least on this particular chapter.
For Apple, the best outcome is a ruling that narrows the applicability of state UCL claims to platform business practices, effectively insulating the App Store model from state-level challenges while the company negotiates with regulators abroad. For Epic, the best outcome is a denial of cert, which would leave the Ninth Circuit’s ruling intact and strengthen the hand of regulators and legislators pushing for broader reforms.
Either way, the case has already reshaped how the technology industry thinks about platform power. The days when a company could build a closed platform, set its own terms, and face no meaningful legal challenge are over. Whether that’s good or bad depends on where you sit. If you’re a developer paying 30% on every transaction, the legal pressure on Apple looks like long-overdue accountability. If you’re an Apple shareholder watching the services margin, it looks like a threat to one of the most profitable business models in corporate history.
Both things can be true at the same time.
The Supreme Court won’t resolve that tension. But it will determine how much room American law gives to companies that control the digital storefronts where billions of dollars change hands every year. That’s a question worth answering.
