Arc Games says more than 7.7 million people have played Star Trek Online since launch. That is a lifetime figure, not the number playing now. There is no official public current total across PC, PlayStation and Xbox; Steam does publish an official live count for Steam players only.
The live number below is Steam concurrency only. It is not an estimate of the whole Star Trek Online population.
Valve measures players currently active in Star Trek Online through Steam. Arc/Epic PC, PlayStation and Xbox players are outside this Steam-only count.
No exact current daily- or monthly-active-player figure is publicly available.
Steam is only one way to play STO on PC. Arc and Epic are separate PC launch routes, and the console populations are separate.
| Where people play | Public live STO count? | What is publicly available |
|---|---|---|
| Arc · PC | No | Current Arc-launcher population is not publicly published. |
| Steam · PC | Yes | Valve exposes current Steam concurrency for Star Trek Online. |
| Epic · PC | No | Current Epic STO population is not publicly published. |
| PlayStation | No | No public STO live or active-player total is exposed. |
| Xbox | No | No public STO live or active-player total is exposed. |
These figures use different metrics. Accounts, captains and lifetime players are not interchangeable with current concurrent players.
| Date | Published figure | What it meant |
|---|---|---|
| 2015 | 2.5m accounts / 3.8m captains | Accounts and player characters, not concurrent players. |
| 2018 | 5.2m players | Cumulative players over STO's lifespan at that point. |
| 2026 | 7.7m+ players | Players drawn to STO since launch; the newest strong first-party lifetime figure located. |
Some sites estimate an all-platform population from public signals. Those figures are models, not direct readings of STO's servers.
Metric rule: live concurrent players, active players, accounts, characters and lifetime players are kept separate throughout this page.
