Steam breaks its own record with 43.5 million users online at once
Steam counted 43,505,724 people logged in at once on Sunday, a new all-time high for the PC games platform. The figure is the highest simultaneous user count in Steam's 23-year history, Eurogamer reported. That is a very big crowd.
The October peak broke Steam's own record for the second time in 2026. Steam had previously passed 42 million concurrent users, meaning people online at the same time, in January. More than 14 million users were actually in a game when the new record landed, which is itself a record.
Two games helped fill the servers. Aion 2 peaked at 397,905 concurrent players at launch. Deadlock reached 262,145 peak concurrent players after a major update. Big numbers. Small share of the total.
The traffic is worth a lot of money. Valve had made an estimated US$15 billion, about £11.10 billion, from Steam by September. Forza Horizon 6, the driving game, was Steam's biggest new release of the year so far by revenue.
Steam is run by Valve as a store and a launcher, the programme players open to buy, download and start games. A concurrent user is anyone logged in, while an in-game user is actively playing. The gap between the two is normal, with millions chatting, shopping or leaving the app open.
What makes this stand out is the scale of both counts moving together. Records used to come from one or the other. This time the shop window and the play sessions peaked at once.
