Steam Users Demolished 100 Exabytes of Data in 2025

The numbers Valve just dropped are enough to make your broadband router burst into tears. If you have ever wondered why your home internet slows to a crawl on a Tuesday evening, we might finally have the culprit. PC gamers have been extraordinarily busy over the last twelve months, chewing through an absolutely monumental amount of bandwidth. It is a staggering milestone that proves just how massive the digital distribution giant has become.

The True Scale of 100 Exabytes

Following details shared by Valve in their official Steam Year in Review 2025, we now know that players downloaded a collective 100 exabytes of games and updates last year. For those of us who do not work in massive data centres, an exabyte is equal to one billion gigabytes. Storing a single exabyte would require roughly 250,000 high-end home PCs.

Let us put that into some proactive industry perspective. Current industry estimates put global internet traffic at roughly 400 to 500 exabytes per month. When you run the maths, this means Steam alone is churning through around 2% of the entire planet's annual internet bandwidth. All of that just so we can keep our massive backlogs updated and ready to play.

A Daily Deluge of Data

Breaking this massive number down makes it slightly easier to process. Reports from various tech outlets highlight that Steam users are averaging 274 petabytes of downloads per day. If we drill down even further, that translates to about 11.42 petabytes every hour, or an eye-watering 190,000 GB of data every single minute.

A huge portion of this volume does not just come from fresh game installations. Every single background update, hotfix, and massive day-one patch contributes heavily to this running total. With modern AAA titles routinely crossing the 100 GB threshold, it is no wonder our data usage is skyrocketing.

Hardware Expansion and User Growth

More gamers means more bandwidth. Valve confirmed the platform is seeing "consistent long term growth". Five years ago, Steam crossed the 25 million concurrent user mark, and they have been adding roughly 3.4 million extra concurrent users per year since. This steady climb has brought them to a new peak of 42 million concurrent users.

Of course, Valve's hardware ambitions are playing a role in keeping players tethered to the ecosystem. We have seen the company push hard into the hardware space, though it has not been without its hiccups. With ongoing Steam Deck OLED shortages causing supply chain headaches, and mixed messaging leaving fans wondering if the Steam Machine is facing a delay, Valve's hardware future is looking a bit murky. Despite these stumbles, the core software platform is absolutely thriving.

⚡ NerdZap's Take

As a family man my gaming time is usually limited to whatever odd hour I can scrape together in the evening. There is nothing quite as soul-crushing as booting up your PC only to be greeted by a 60 GB update for a game you just wanted to play for twenty minutes.

That being said, seeing these 100 exabyte figures makes me realise just how robust Valve's infrastructure actually is. To serve 190,000 GB of data a minute without the entire network catching fire is a monumental feat of engineering. Valve has effectively built the backbone of modern PC gaming, and they are moving data on a scale that rivals entire nations. Now, if you will excuse me, I need to go delete some old games to free up space on my SSD.
