The Steam 30% cut lawsuit is actually two separate antitrust cases against Valve Corporation: a certified class action by roughly 30,000 game publishers in a Seattle federal court, and a certified consumer collective action on behalf of up to 14 million UK gamers in London’s Competition Appeal Tribunal. Both challenge the same core practice — Valve’s 30% commission on Steam sales, combined with rules that allegedly stop developers from offering their games more cheaply on rival stores. Neither has reached trial as of mid-2026.
What the Lawsuits Actually Allege
The complaints are not simply that 30% is too high. They are that Valve uses its dominance over PC game distribution to keep the rate from being competed down. The mechanism, as plaintiffs describe it, is a set of price-parity rules they call Platform Most-Favored-Nation (PMFN) clauses: developers who sell on Steam cannot offer the same game at a lower price, or with better content, on a competing storefront.1A&O Shearman.

According to court filings, developers who break parity risk reduced promotional visibility on Steam or delisting, with Valve employees warning publishers that cheaper prices elsewhere could cost them placement.2CREATE.ac.uk. Parity and Power: Steam’s Antitrust Reckoning in Wolfire v. Valve The result, plaintiffs argue, is that rivals charging less — the Epic Games Store at 12%, Microsoft’s store at 15% — cannot translate their lower commissions into lower consumer prices, because developers are contractually barred from passing the savings through.3Hagens Berman. In re Valve Antitrust Litigation The complaint cites Discord’s 2018 game store, which launched with a 10% commission and shut down a year later, as an example of a would-be competitor that could not break through the parity regime.4ClassAction.org.

Steam Keys sit at the center of the dispute. Valve gives developers a default allocation of 5,000 free keys at launch that can be sold on other storefronts without Valve collecting any commission, but its guidelines state that developers should not “give Steam customers a worse deal than Steam Key purchasers.” Developers whose “sole business is selling Steam Keys and not offering value to Steam customers” can lose key access entirely.5Valve. Steam Keys Documentation Plaintiffs characterize these conditions as a de facto price-parity enforcement mechanism; Valve says it has no legal duty to let developers use free keys to undercut Steam.6NME.

The U.S. complaint also alleges Valve ties its Steam gaming platform to its store, forcing publishers who want to reach Steam users to sell through the Steam Store, and bars consumers from using alternative payment processors for in-game purchases.3Hagens Berman. In re Valve Antitrust Litigation The UK claim adds that Steam “locks in” consumers by requiring any add-on content for a Steam-purchased game to be bought through Steam as well.7BBC.

The US Developer Class Action
The U.S. case, In re Valve Antitrust Litigation, Case No. 2:21-cv-00563, is in the U.S. District Court for the Western District of Washington. It began on April 27, 2021, when indie studio Wolfire Games filed suit alongside individual consumer plaintiffs; a separate consumer complaint, Colvin v. Valve, was filed shortly afterward and the two were consolidated in May 2021.8Game Developer. Overgrowth Dev Wolfire Games Files Antitrust Lawsuit Against Valve Over Steam Fees The claims are brought under Sections 1 and 2 of the Sherman Act and Washington’s Consumer Protection Act.
On November 25, 2024, Judge Jamal N. Whitehead certified a class of approximately 30,000 to 32,000 game publishers, rejecting Valve’s argument that differences among developers — including over Steam Keys — made the class unmanageable.1A&O Shearman. Game Developers Win Class Certification in Valve Antitrust Case Plaintiffs’ economist Dr. Steven Schwartz concluded that in a competitive market Valve’s commission would be around 17–18% rather than 30%, with retroactive overcharges to developers exceeding $3.1 billion.2CREATE.ac.uk. Parity and Power: Steam’s Antitrust Reckoning in Wolfire v. Valve Judge Whitehead denied Valve’s motion to exclude that testimony, ruling the methods “reliable and within the norms for admission.”9Secretariat.

The consumer side of the U.S. case followed a separate track because of a mandatory arbitration clause in Valve’s Steam Subscriber Agreement, which was later amended. Cohen Milstein was appointed sole Interim Lead Class Counsel for the consumer class on May 2, 2025, and an amended consumer complaint was filed on June 27, 2025. The consumer class has not yet been certified.11Cohen Milstein. In re Valve Antitrust Litigation
As of late June 2026, no trial has taken place. Valve filed a sealed summary judgment motion on the developer claims, both sides have moved to exclude each other’s experts, and Valve filed an offer of judgment on June 17, 2026 — a procedural step that can shift litigation-cost liability if the verdict does not exceed the offer.12CourtListener.

The UK Consumer Collective Action
The UK case was filed on June 5, 2024, in the Competition Appeal Tribunal by Vicki Shotbolt Class Representative Limited, an entity created to bring the claim. Shotbolt, who founded the children’s digital rights organization Parent Zone, serves as class representative.13Milberg London. PC Gamers Win the First Battle Against Valve Corporation The claim is brought under Section 18 of the Competition Act 1998 and alleges abuse of a dominant market position.
The proposed class covers 9.3 to 14.2 million consumers who purchased PC games or add-on content through Steam or other platforms since June 2018 — or since January 2010 for consumers domiciled in Scotland. Total damages sought are £656 million, with average individual losses estimated between £22 and £44 per class member.14ICLG. Steam Owner Valve Forced to Face GBP 656M Collective Action
On January 26, 2026, the tribunal certified the case on an opt-out basis, meaning UK consumers who meet the class definition are automatically included unless they choose to opt out.7BBC. Steam Owner Valve Faces £656m Lawsuit Over Game Prices A formal Collective Proceedings Order followed on March 11, 2026.15Steam You Owe Us. FAQs Valve had opposed certification by arguing that Steam Keys made its actual commission income “unknown and unknowable” and that the damages methodology was unreliable; the tribunal held that those were disputes for later and not reasons to deny certification.14ICLG.

A case management conference was scheduled for June 22, 2026. No trial date has been set, and the tribunal described the damages methodology as “necessarily provisional” pending disclosure of Valve’s internal data.17Competition Appeal Tribunal.

How Valve Is Defending the Cases
Valve’s position is that the 30% commission is not a product of market power. The company has argued that the rate predates any alleged dominance, having been set when competition was “vibrant” and Valve had “zero market share,” making it “implausible that 30% is supracompetitive.” It notes that the 30% figure is an industry standard and that rivals like Epic actively compete at lower rates, which Valve says shows the market is functioning. On Steam Keys, Valve maintains there is “no duty under antitrust law to allow developers to use free Steam Keys to undersell prices for the games they sell on Steam — or to provide Steam Keys at all.”6NME. Valve Defends Taking 30 Per Cent Cut of Steam Sales Valve has also disputed plaintiffs’ estimate that it holds 75% of PC game distribution, calling the figure “devoid of any factual support.”
Valve does already discount its commission for the largest titles: the rate drops to 25% after a game generates $10 million in revenue and to 20% after $50 million.8Game Developer. Overgrowth Dev Wolfire Games Files Antitrust Lawsuit Against Valve Over Steam Fees Plaintiffs say the tiered structure only confirms the problem, because the 30% standard rate still applies to the vast majority of developers who never hit those thresholds.
Wider Context
The Steam cases are part of a broader challenge to the 30% platform fee that originated with Apple’s App Store and spread across digital distribution. Epic Games sued Apple and Google over the same rate beginning in 2020,18The New York Times. Apple, Google and a 30% Tax and Epic CEO Tim Sweeney has publicly backed the UK claim against Valve, calling the Steam commission a “junk fee” and noting that iOS and Android developers can now steer users to competing payment methods after U.S. court rulings, while Steam still prohibits this.19PC Gamer. Epic Games Boss Tim Sweeney Voices Support for $900 Million Steam Lawsuit Epic is not a party to either Valve case.
Whether the courts ultimately agree that Valve’s 30% commission and parity rules cross from aggressive business strategy into antitrust violation will turn on how the relevant market is defined, whether the PMFN clauses actually block competition, and how damages are measured. Those questions remain open on both sides of the Atlantic.
