In an era dominated by headline-grabbing antitrust clashes against tech giants like Google and Apple, another courtroom drama has quietly gathered steam. This time, the spotlight swings to Valve, the company behind Steam — the digital marketplace that towers over PC gaming like a central railway station through which nearly every train must pass.
UK Tribunal Clears Path for High-Stakes Case
A UK competition tribunal has allowed a sweeping collective action to move forward against Valve, potentially exposing the company to damages of £656 million (about $900 million). The case was filed in 2024 by digital rights campaigner Vicki Shotbolt, representing an estimated 14 million UK Steam users who bought games or content on the platform from 2018 onward, according to reporting by the BBC.
If Valve fails to settle the dispute or convince the court of its innocence, the financial consequences could be enormous — rivaling some of the most expensive tech lawsuits in recent memory.
Allegations of Market Control and Unfair Pricing
Claims of Platform Parity Obligations
At the heart of the Valve $900 Million Lawsuit is the claim that Steam operates less like a marketplace and more like a toll road with no detours. The lawsuit alleges Valve enforces so-called Platform Parity Obligations, rules that allegedly prevent game publishers from offering their products on other platforms at better prices or terms than those available on Steam.
Critics argue these restrictions choke competition, discouraging alternative stores and locking publishers into Valve’s ecosystem.
