Basketball Champions League 2026-27: Complete Season Preview
As the 2026-27 campaign gets under way, attention is turning to one of Europe’s most competitive club competitions. Rytas Vilnius enter the new season as reigning champions after their dramatic 2026 triumph, while established contenders and ambitious newcomers prepare to challenge for the trophy.
The new season brings a mixture of returning powerhouses, national champions and clubs looking to make their mark on the continental stage. With 54 teams involved across the qualification rounds and Regular Season, there is plenty of opportunity for unexpected results before the competition reaches its decisive stages.
Across arenas throughout Europe, supporters will be watching closely as teams face different playing styles, demanding travel schedules and increasingly important fixtures. Here is how the competition works, when the key stages take place and which teams could challenge for the title.
What Is The Basketball Champions League?
The Basketball Champions League is a European club basketball competition that began in 2016-17 and is built around sporting qualification through domestic leagues. It brings together leading clubs from across Europe, including national champions and teams that have earned their place through their domestic performances.
The competition has developed into an important part of the European basketball calendar, with clubs from established basketball nations competing alongside teams from countries with smaller domestic leagues. The 2026-27 edition features teams from 29 European countries, including many national champions.
The tournament has also developed a diverse list of champions. Spain remains the most successful nation in BCL history with six titles, but the 2026 Final Four added Lithuania to the list of countries with a winner when Rytas Vilnius defeated AEK BC 92-86 after overtime in Badalona. Rytas became the seventh different club to win the competition.
How Does The Basketball Champions League Work?
The 2026-27 Basketball Champions League features 54 teams in total. The campaign begins with two Qualification Round Tournaments involving 24 clubs, with two teams ultimately earning places in the 32-team Regular Season. The other 30 Regular Season places are awarded directly on sporting criteria.
The Regular Season consists of eight groups of four teams. Each club plays its three group opponents home and away, meaning six games in total. The group winners progress directly to the Round of 16, while the teams finishing second and third enter the Play-Ins. Fourth-placed teams are eliminated.
The Play-Ins are best-of-three series, with the second-placed teams receiving home advantage. The eight winners join the eight group winners in the Round of 16.
The Round of 16 then consists of four groups of four, again using a home-and-away round-robin format. The top two teams from each group progress to the Quarter-Finals, which are played as best-of-three series. The four Quarter-Final winners advance to the Final Four, where the semi-finals and final are played over one weekend.
When Does The Basketball Champions League Start?
The 2026-27 Basketball Champions League campaign officially began with the Qualification Round Tournaments on 14 September 2026. Those tournaments ran through 20 September and determined the final two teams to join the Regular Season.
The 32-team Regular Season begins on Tuesday 6 October 2026 and runs until 23 December 2026. Fixtures are generally scheduled for Tuesdays and Wednesdays to reduce clashes with domestic league programmes.
The Play-Ins take place in January, followed by the Round of 16 from late January into March. The Quarter-Finals are scheduled for April, before the Final Four brings the competition to a conclusion in May 2027. The official BCL calendar lists 16 May 2027 as the end date for the season.
How Many Teams Are In The Basketball Champions League?
The 2026-27 competition involves 54 teams in total, representing 29 European countries. Of those 54 clubs, 32 compete in the Regular Season, with 30 receiving direct qualification and two entering through the Qualification Rounds.
The Regular Season is therefore made up of eight groups containing four teams each. The 32 clubs include the defending champions Rytas Vilnius, along with established BCL names such as Unicaja, Galatasaray MCT Technic, SIG Strasbourg, AEK BC and Telekom Baskets Bonn.
The qualification system also creates opportunities for less familiar clubs. RASTA Vechta, for example, won the second Qualification Round Tournament and returned to the Regular Season, while Salon Vilpas won the first tournament to secure its place in the main competition.
This combination of established contenders and ambitious newcomers is one of the defining features of the BCL. A strong domestic season can open the door to European competition, while a successful qualifying campaign can transform a club’s season.
How Many Games Are In a Basketball Champions League Season?
The 2026-27 Basketball Champions League is scheduled to feature a minimum of 194 games across eight months of competition. That figure includes the Qualification Rounds, Regular Season, Play-Ins, Round of 16, Quarter-Finals and Final Four.
Each Regular Season team plays six games in its group. The eight group winners then advance directly to the Round of 16, while 16 second- and third-placed teams compete in the Play-Ins for the remaining eight places. The Round of 16 adds another six games for each participating club because it is played in four groups of four on a home-and-away basis.
The Quarter-Finals are best-of-three series, meaning teams can play two or three games depending on the result. The Final Four then consists of two semi-finals and a final across a single weekend.
For clubs that go all the way, the workload therefore extends well beyond the six-game Regular Season. Squad depth, player management and the ability to maintain form over several months can become just as important as individual talent.
Who Won The Basketball Champions League 2026?
Rytas Vilnius won the 2026 Basketball Champions League, claiming the first BCL title in the club’s history. They defeated AEK BC 92-86 after overtime in the Final Four final at the Palau Municipal d’Esports in Badalona, Spain.
The final produced one of the most dramatic comebacks in BCL history. Rytas trailed by 20 points during the third quarter before producing a huge fourth-quarter turnaround to force overtime. They then outscored AEK 12-6 in the extra period to secure the trophy.
Rytas’ victory also made Lithuania the fifth country to produce a BCL champion, following Spain, Greece, Italy and Germany. It was the seventh different club to win the competition since its launch.
The defending champions now begin the 2026-27 campaign with the challenge of becoming the first team to successfully defend the BCL title since the competition’s back-to-back championship runs earlier in its history.
Who Are Favourites To Win The Basketball Champions League 2026-27?
Rytas Vilnius naturally enter the season among the teams attracting the most attention. The Lithuanian champions have already demonstrated that they can navigate the BCL’s later stages, although they will have to deal with changes to their coaching staff and roster after their historic title run. The official BCL preview nevertheless identifies them as favourites in Group A.
Galatasaray MCT Technic are another leading contender. The Turkish club reached the Quarter-Finals last season and has undergone a significant roster rebuild under head coach Gianmarco Pozzecco. The BCL’s own Season 11 preview describes them as early favourites to top Group B.
Unicaja remain an important name to watch after winning consecutive BCL titles before their 2025-26 campaign ended in the Quarter-Finals. ALBA Berlin, Asisa Joventut, SIG Strasbourg, AEK BC and other experienced clubs will also have ambitions of reaching the latter stages.
The competition is difficult to predict because the format provides several opportunities for teams to recover from setbacks. A club that misses out on first place in its Regular Season group can still reach the Round of 16 through the Play-Ins, while the best-of-three Quarter-Finals can produce further twists.
