Valve is facing a legal battle over allegations of imposing excessive commissions on publishers using its Steam platform, with potential damages reaching £656 million. The lawsuit, initiated in June 2024, represents the interests of up to 14 million UK consumers who purchased games via Steam since 2018. Vicki Shotbolt leads the case, claiming Valve restricts publishers from offering lower prices on competing platforms and locks customers into its ecosystem. Valve's commission is reportedly as high as 30 percent. The London Competition Appeal Tribunal has allowed the case to proceed, despite Valve's objections. This is not the first scrutiny Valve has faced; a previous antitrust lawsuit from Wolfire Games was dismissed in late 2021 but was refiled and merged with another claim in 2022, gaining class action status by November 2024.
