Valve is officially heading to trial over a massive £656 million lawsuit, roughly $900 million, after a UK tribunal ruled the case can proceed. The legal action, filed by digital rights campaigner Vicki Shotbolt, claims Steam has been overcharging millions of British gamers for years through anti-competitive practices and excessive commissions.
The lawsuit represents up to 14 million UK consumers who purchased games or DLC through Steam since June 2018.
According to the complaint, Valve’s dominant position in the PC gaming market has allowed it to impose unfair pricing structures, with each affected user potentially overpaying between £22 and £44 during this period. If successful, those same users could see compensation checks heading their way.
The heart of the accusations
The case centers on two major complaints. First, Valve’s standard 30% commission on every sale, which critics argue is excessive and gets passed directly to consumers through inflated game prices.
Second, and perhaps more damaging, are the alleged “price parity” clauses that prevent publishers from selling their games cheaper or releasing them earlier on rival platforms like Epic Games Store or GOG.

Shotbolt’s legal team also points to Steam’s ecosystem lock-in, where players who buy a base game on Steam must purchase any additional content, DLC, expansions, season passes, exclusively through the platform. This practice, according to the lawsuit, eliminates consumer choice and keeps gamers trapped within Valve’s marketplace.
The Competition Appeal Tribunal in London rejected Valve’s attempts to dismiss the case, which argued the claims lacked proper methodology for calculating harm.
Valve also defended its commission rate as standard across the industry, noting that PlayStation, Xbox, and Nintendo all charge similar percentages. The tribunal wasn’t buying it.
What this means for PC gaming
Steam is the undeniable titan of PC gaming. Over 19,000 games launched on the platform in 2025 alone, generating billions in revenue. Valve has also expanded into hardware, most notably with the Steam Deck, strengthening its ecosystem beyond software sales. This lawsuit isn’t just about money, it’s about whether Steam’s market dominance has given Valve unchecked power over developers and gamers alike.
Valve insists the accusations don’t hold water, particularly regarding Steam Keys, which allow publishers to sell game codes through third-party retailers like Humble Bundle and Fanatical without Valve taking a cut. The company claims this reduces the real impact of its commission structure, but the tribunal dismissed this defense as insufficient.
Similar lawsuits are brewing in the United States, where class action status was granted in November 2024. If the UK case succeeds, it could force Valve to restructure how Steam handles pricing, commissions, and platform restrictions, changes that would ripple across the entire PC gaming industry.
For now, the case moves forward to trial, backed by over £18.6 million in funding. The timeline remains unclear, but legal battles of this scale typically take years to resolve. Even if Valve loses, immediate price drops are unlikely.
What’s certain is that Steam’s business model is under serious scrutiny, and the outcome could redefine the relationship between platforms, developers, and players for years to come.
