Resolution criteria

The peak concurrent player count will be determined by SteamDB's official records. Resolution will be based on the highest concurrent player count recorded on SteamDB's Marathon Server Slam charts at any point during or after the event window (February 26 – March 2). The market resolves to the actual peak count achieved.

Background

Marathon is an upcoming extraction shooter from Destiny and Halo developer Bungie, with a full release scheduled for March 5, 2026. The Server Slam has already surpassed 143,000 concurrent players on Steam in its first few hours. For context, ARC Raiders' final playtest before launch peaked at 189,000 concurrent players on Steam, providing a benchmark for comparison.
