Format for the 2025-26 Turkish Airlines EuroLeague Regular Season, Play-In Showdown, Playoffs and Final Four.
Round-robin format, for a total of 38 games played by each of the 20 teams between Tuesday, September 30, 2025, and Friday, April 17, 2026. The best six teams in the standings advance directly to the playoffs. Teams ranked seventh through 10th advance to the Play-In Showdown.
The third year of the Play-In Showdown will take place on Tuesday, April 21, and Friday, April 24. The seventh- and eighth-place teams from the regular season will face off in a single game to clinch a spot in the best-of-five quarterfinals vs. the regular season's second-ranked team. The ninth- and 10th-place teams will play a single game whose loser will be eliminated. The winner of that game will challenge the other Play-In Showdown game loser – either the seventh- or eighth-place team – to decide the final playoff spot for a best-of-five series vs. the top-ranked regular-season team. Each Play-In Showdown game will be hosted by the team with the better regular-season finish.
Eight teams – the top six from the regular season and the two survivors of the Play-In Showdown – will be split into four best-of-five playoff series matchups, based on which seed they have entering the playoffs. These games get underway on Tuesday, April 28, and will end no later than Wednesday, May 13. The first two games and a potential fifth game in each series will be hosted by the higher-placed team from the regular season. Series winners advance to the Final Four.
The 2026 Turkish Airlines EuroLeague Final Four will take place on the fourth weekend in May. The semifinals will be on Friday, May 22. Friday's semifinal losers will meet on Sunday, May 24, in the Third-Place Game, which will be followed by the semifinal winners going head to head in the Championship Game for the right to raise the 2025-26 season trophy.
