Valve revealed that Steam has been steadily growing for the past five years, with growth being estimated at around 3.4 million additional users per year. Five years ago, Steam crossed the 25 million concurrent user mark, and in 2025, it reached 42 million peak concurrent users. With so many PC gamers now adopting the platform, Valve is required to provide those games with a steady stream of new titles they can download at maximum speed. Valve is and has been doing that, and the stats on those downloads are quite eye-watering.

According to Valve, in 2024, Steam users downloaded 80 exabytes of data, which quickly rose to 100 exabytes in 2025. To put that number into perspective, Steam users are averaging 274 petabytes of installs and updates per day, which equates to 11.42 petabytes per hour of downloads, or approximately 190,000 gigabytes of data per minute. Additionally, if you were wondering how many 1TB SSDs in gaming PCs 100 exabytes would fill up, it's approximately 100 million 1TB SSDs.

"Five years ago, Steam was growing steadily and crossed the 25 million concurrent user mark for the first time. In the years since, we've grown at a pace of around 3.4 million additional concurrent users per year, reaching 42 million peak concurrent users.

All those users are downloading a lot of content. In 2024 we delivered about 80 exabytes to customers, and in 2025 that grew to 100 exabytes. It's hard to make sense of such a huge number, but just for fun: Steam users are averaging 274 petabytes of installs and updates per day- that's 11.42 petabytes per hour, which is about 190,000 GB of data per minute," writes the Steam Team
