In a major blow to the world’s leading PC gaming platform, the Competition Appeal Tribunal (CAT) has ruled that a massive £656 million collective lawsuit against Valve Corporation can proceed to trial. The decision, handed down on January 26, 2026, officially certifies the case as an “opt-out” collective action, potentially involving up to 14 million UK-based consumers.
The Allegations: A “Tax” on Gaming?
The lawsuit, led by Vicki Shotbolt, alleges that Valve has exploited its dominant market position through the Steam platform. The legal team argues that Valve’s 30% commission on sales—combined with “anti-steering” rules that force in-game purchases through Valve’s own payment systems—amounts to an unfair price passed directly to consumers.
Furthermore, the claim targets Valve’s “Price Parity” obligations, which allegedly prevent developers from offering their games cheaper on rival platforms, effectively “locking in” high prices across the entire PC gaming market.
Valve’s Failed Defense
Valve attempted to block the certification, arguing that the claim was too complex to calculate accurately. They specifically pointed to “Steam Keys”—free codes that allow developers to sell games on other sites while still using Steam’s features—as a factor that makes determining a “fair price” nearly impossible.
The Tribunal, however, disagreed. In his judgment, the Chair noted that while the math may be complex, the PCR (Proposed Class Representative) has a “workable methodology.” The court ruled that Valve would simply have the benefit of any “reasonable doubt” during the final damages assessment at trial.
What’s Next for UK Gamers?
Because this is an opt-out case, any UK resident who purchased games or add-on content on Steam (or other PC platforms affected by Steam’s pricing) since June 2018 is automatically included in the claimant class.
The next step will be a Case Management Conference to set the timeline for disclosure and the eventual trial. If Valve loses, the company could be forced to pay out hundreds of millions of pounds, with individual gamers potentially receiving between £22 and £44 in compensation.
