Microsoft and Valve Face Steam Price-Fixing Lawsuit

Two big companies, Microsoft and Valve, are being sued. The case is called a class action. A class action is one big court case where many people sue together as a group.

The lawsuit says the two companies made a secret deal. The deal kept the price of PC games high. People who bought games say they paid too much because the companies agreed not to compete on price.

Steam is Valve’s huge online store for PC games. The lawsuit says Microsoft joined Valve’s pricing plan instead of fighting it. Here is what the case says, in plain words.

What the lawsuit claims

The case was filed in a US court. The court is the US District Court for the Western District of Washington. It was filed on May 31, 2026.

The lawsuit says the two companies made a “horizontal price-fixing agreement”. Price-fixing is when rivals secretly agree on a price. They do this instead of competing. “Horizontal” just means the deal is between two rivals at the same level of the market.

The lawsuit says Microsoft “chose to join Valve’s cartel”. A cartel is a group of companies that team up to control prices. The people suing say this led to higher prices. They also say it gave buyers less choice and lower quality.

The MFN clause explained

The main part of the case is a rule called “price parity”. It is also called an MFN clause. MFN stands for Most Favored Nation. It is a promise in a contract that one side always gets the best deal.

In simple words, the rule means a game maker cannot sell the same game cheaper somewhere else than on Steam. So even if another store took a smaller fee, the game maker could not pass that saving to buyers. The lawsuit says this goes back to a contract from 2011.

This is why the case talks about Steam’s 30% cut. The 30% cut is the part of each sale that Steam keeps for itself. The MFN rule is what turns this into an antitrust case, not just a fight about fees. Antitrust laws are rules that stop companies from unfairly killing off competition.

How big is the market

The people suing say Valve and Microsoft together control “at least 80%” of PC game sales in the United States. Here, that means how games get sold and sent to players.

They are asking the court for money. This includes treble damages. Treble damages means the court can give them up to three times the money they actually lost. They also want an injunction. An injunction is a court order. Here, it would order Microsoft to stop any such price-fixing deal.

Why it matters (especially for India and founders)

This case could change how online stores set their fees. If the MFN argument wins, stores may lose the power to force price parity. That could mean cheaper games and more choice for players. This includes players in India.

For founders, the lesson is clear. This is true for anyone building an app store, a marketplace, or a game platform. MFN and price-parity rules are now getting a lot of legal heat around the world. Courts and government watchdogs are watching how platforms use their power over prices.
