This market will resolve to "Yes" if any player joins or leaves MOUZ's main CS2 roster (defined as players listed with status = "Starter" in the "Players of MOUZ" table on HLTV: https://www.hltv.org/team/4494/mouz#tab-rosterBox) before the 2026 IEM Cologne Major begins. Otherwise, this market will resolve to "No". As of market creation the active starter roster consists of the following five players: Brollan, Spinx, torzsi, Jimpphat, and xertioN. Name changes or aliases referring to the same player do not qualify as roster changes. For the purpose of this market, "roster change" refers to any official signing, transfer, benching to inactive/reserve, release, retirement, or departure of a player from the active starter lineup. This includes adding new players (transfers, free agent signings, or loans), removing players (to bench/inactive, free agency, or other teams), or any change resulting in a different 5-player active roster on HLTV. Coach changes and temporary stand-ins for a single event will not count. For matches and events, the stand-in appears in the active 5-player lineup but with a clear marker (e.g., [SI]) to distinguish them from the core roster. The primary resolution source for this market will be HLTV; however a consensus of credible reporting may also be used.
