Roblox just set a new concurrent user record – 47.3 million players online at once during a weekend ‘war’ between two viral games, and that matters because it beat Steam’s peak and shows how huge traffic can cluster around a couple of hit experiences.
Roblox smashed the total concurrent-users mark, reaching 47.3 million at the same time and nudging past Steam, which peaked at 41.2 million in March 2025. Hundreds of small titles didn’t drive this – just two massive hits carried most of the load. The spike came after a weekend ‘war’ between two viral experiences, Grow a Garden and Steal a Brainrot, where both games staged highly publicized bouts of Admin Abuse to pull in players.
In the end, Grow a Garden recorded about 22 million concurrent players, while Steal a Brainrot hit more than 15 million. Together those two experiences pulled roughly 37 million people at once – about 77% of the platform peak. The timing makes the number even more striking. Steam’s high earlier in 2025 stood as a benchmark for platform-wide concurrent play, but Roblox cleared it by over six million users.
The milestone also arrives amid renewed conversations around Roblox’s safety standards and moderation. As the user base grows, the platform faces pressure to pair scale with stronger protections. Some recent coverage has been tracking Roblox’s massive reach and record-shattering sessions – here’s a recent report that looked at how single games can spike platform numbers. Got thoughts?
