Microsoft and Valve Face Steam Price-Fixing Lawsuit
A new class action has put Microsoft and Valve in the spotlight. The Microsoft Valve Steam price-fixing lawsuit claims the two companies made a secret deal that kept PC game prices high. A class action is a legal case where many people sue together as one group. The complaint says shoppers paid more because the companies agreed not to compete on price.
Steam is Valve’s giant online store for PC games. The case argues that Microsoft chose to join Valve’s pricing system instead of fighting it. Here is what the lawsuit says, in simple terms.
What the lawsuit claims
The case was filed in the US District Court for the Western District of Washington. The complaint was filed on May 31, 2026.
It alleges that Microsoft and Valve entered a “horizontal price-fixing agreement”. Price-fixing is when rivals secretly agree on prices instead of competing. “Horizontal” means the deal is between two competitors at the same level of the market.
The complaint claims Microsoft “chose to join Valve’s cartel” rather than compete with Steam. A cartel is a group of companies that team up to control prices. The plaintiffs say this led to higher prices, less choice and lower quality for buyers.
The MFN clause explained
At the centre of the case is a “price parity” rule, also called an MFN clause. MFN stands for Most Favored Nation. It is a contract promise that one side will always get the best available deal.
In plain words, an MFN here would mean a game maker cannot sell the same game cheaper somewhere else than on Steam. So even if another store charged a smaller fee, the developer could not pass the savings to shoppers. The lawsuit traces this back to a 2011 distribution contract.
This is why the case focuses on Steam’s well-known 30% cut. The 30% cut is the share Steam keeps from each sale. The MFN argument is what makes the case an antitrust claim, not just a fee complaint. Antitrust laws are rules that stop companies from unfairly killing competition.

How big is the market
The plaintiffs say Valve and Microsoft together control “at least 80%” of PC game distribution in the United States. Distribution here means how games get sold and delivered to players.
They are seeking damages, including treble damages. Treble damages means the court can award up to three times the actual loss. They also want an injunction, which is a court order, to stop Microsoft from keeping any such price-fixing deal.
Why it matters (especially for India and founders)
This case could reshape how digital stores set their fees. If the MFN argument wins, platforms may lose the power to force price parity. That could mean cheaper games and more choice for players, including in India.
For founders, especially those building app stores, marketplaces or game platforms, the warning is clear. MFN and price-parity clauses are drawing legal heat worldwide. Regulators and courts are watching how platforms use their power over pricing.
