New data estimates from Alinea Analytics put a number on Valve's successful PC games storefront. According to the firm's latest estimates, Steam could have made up to $11.1 billion in gross sales revenue throughout the first half of the year. This milestone could make 2026 a record-breaking year for PC gaming. One important thing to remember is that this is the total sum of all the earnings and sales from games and content on Steam--it doesn't just represent Valve's cut, but the whole pie.

"Steam's full-year revenue has climbed from around $5.5B in 2017 to roughly $20B in 2025," Alinea's Rhys Elliott said in the coverage. The FTC v Microsoft trial from 2023 also revealed that Valve's Steam storefront was estimated to have made $7 billion in 2021, illustrating a major boost to sales over nearly 10 years.

Another interesting tidbit: Most of Steam's earnings come from back catalog games. This makes sense, as Steam is known for its steep discounts and sales on older titles. This mechanism has proven to be very successful for everyone involved, with publishers like Capcom routinely generating significant multi-million sales on the strength of Steam's versatile storefront.

The sheer volume of games is another reason for the accelerated sales. There are more titles on Steam now than ever before, and that number continues to grow with every passing quarter. Heavy-hitters and breakout successes are also major contributors, with major titles like Slay the Spire 2, Subnautica 2, and Meccha Chameleon all making multi-million sales on PC.
