Overwatch has around 52,000 concurrent players on Steam right now, with a 24-hour peak of 78,402 and a 30-day average of 58,481. Third-party trackers put the all-platform figure somewhere between 370,000 and 540,000 concurrent and roughly 11-17 million monthly, but Blizzard doesn’t publish a live player counter, so every total-population number is an estimate. Steam data is measured directly and is the only figure we have that can be checked.
