This market will resolve to the over ("O") outcome if the Boston Celtics record more than 50.5 wins during the 2026-27 NBA regular season. Otherwise, this market will resolve to the under ("U") outcome. Only wins in 2026-27 NBA regular-season games count. NBA Cup group-play and knockout games other than the NBA Cup Championship game are regular-season games and count. Preseason, NBA Cup Championship game, Play-In Tournament and playoff games do not count. If at any point it becomes impossible for the Boston Celtics to finish the 2026-27 NBA regular season above the listed line, this market will resolve to the under ("U") outcome. If the 2026-27 NBA regular season is cancelled, shortened, or postponed after April 25, 2027, 11:59 PM ET, this market will resolve to the over ("O") outcome if the Boston Celtics recorded more wins than the listed line in games played by that time, or to the under ("U") outcome if the Boston Celtics could not have finished above the listed line even if their full original 82-game schedule had been played. Otherwise, this market will resolve to "50-50". The primary resolution source will be official information from the NBA; however, a consensus of credible reporting may also be used.
