International Basketball Events 2026: The Complete Calendar for the Rest of the Year

If you follow the game beyond the NBA, the back half of 2026 is loaded. National teams are deep into the Road to Qatar 2027, the women’s world championship lands in Berlin, and 3×3 basketball keeps expanding its global footprint with stops on five continents. Whether you are a fan plotting which weekends to keep free or a bettor tracking form through resources such as Top20 UK betting sites, this is your one-stop guide to the international basketball events that matter between now and December 31, 2026.

The headline act: FIBA Women’s Basketball World Cup 2026

The single biggest event on the calendar is the FIBA Women’s Basketball World Cup 2026, staged in Berlin, Germany, from September 4 to 13. It is the 20th edition of the quadrennial world championship and the second time Germany has hosted, after 1998. Sixteen teams from four confederations will compete across two venues in the German capital.

Germany qualifies automatically as host and is joined by the four 2025 Continental Cup winners — Australia, Belgium, Nigeria and the United States — with the remaining places decided through a series of qualifying tournaments. The United States arrives, as ever, as the team to beat, but the women’s game has tightened at the top in recent cycles, and a Berlin crowd will give the host nation a genuine lift. Ten days, two arenas, one champion: if you watch only one international tournament this year, make it this one.

The Road to Qatar 2027: World Cup qualifiers

Running underneath everything else is the FIBA Basketball World Cup 2027 Qualifiers, a 15-month marathon that decides 31 of the 32 places at the 2027 World Cup in Doha (host Qatar is already in). Eighty national teams from Africa, the Americas, Asia and Oceania, and Europe are battling through six windows. Three of those windows fall in the second half of 2026.

Window 3 — June 29 to July 7

The third window closes out the First Round in most regions. Crucially, this is a window in which NBA players are eligible to suit up for their national teams, so expect bigger names and bigger crowds than the earlier windows produced. Every result carries over into the next phase, so nothing here is a dead rubber.

Window 4 — August 24 to September 1

This window opens the Second Round in Europe and Asia. Teams keep the points they earned in the First Round and then play home-and-away against three fresh opponents drawn from another group. Protecting home court becomes enormous: a European side that holds serve at home in late August can build a decisive cushion before the final windows.

Window 5 — November 23 to December 1

The penultimate window of the entire cycle and arguably the most dramatic of 2026. Some teams will be in a position to mathematically clinch a Second Round spot, while others will be staring down genuine do-or-die fixtures. With only the final February 2027 window left after this, the standings start to crystallise here.

Youth on the rise: U17 World Cups

Summer is youth-tournament season, and 2026 delivers two showcases for the sport’s next generation.

The FIBA U17 Men’s Basketball World Cup tips off in Istanbul, Türkiye, from June 27 to July 5. Istanbul is one of the great basketball cities, and the event doubles as a scouting goldmine — many of these teenagers will be draft conversations within a few years. The United States heads in chasing what would be an eighth title in as many tournaments, an extraordinary streak of dominance at this level.

A fortnight later, the FIBA U17 Women’s Basketball World Cup runs in Brno, Czechia, from July 11 to 19. Both events are part of FIBA’s multi-year hosting model for youth competitions, developed with the Turkish and Czech federations.

The 3×3 explosion

Three-on-three basketball has gone from playground variant to Olympic medal sport, and its 2026 calendar is the busiest of any discipline. While the flagship FIBA 3×3 World Cup (Warsaw, June 1–7) wraps just before this window opens, several major 3×3 events remain.

3×3 at the Commonwealth Games

3×3 returns to the Commonwealth Games in Glasgow, Scotland, with tournaments running July 24 to 29 and finals on August 2 at the SEC Centre. The able-bodied competitions expand to twelve teams per gender, alongside wheelchair tournaments — a sign of how quickly the format is being absorbed into multi-sport events.

FIBA 3×3 Europe Cup

The continental crown is decided in Antwerp, Belgium, from September 11 to 13, bringing Europe’s best half-court squads together in a fast, high-scoring format that suits a festival atmosphere.

FIBA 3×3 U23 World Cup

The age-group world title heads to Wuhan, China, from September 15 to 19, with twenty men’s and twenty women’s teams. China hosting always guarantees a vibrant, packed event.

FIBA 3×3 AmeriCup and Africa Cup

The Americas crown their champions in San Salvador, El Salvador, from October 28 to November 1, and the year’s 3×3 program closes in Antananarivo, Madagascar, where the FIBA 3×3 Africa Cup runs December 3 to 6.

What about the club game?

Two of the world’s strongest club competitions also reignite in the autumn. The new EuroLeague season and the NBA2026–27 campaign both tip off in October, and while they are club rather than national-team events, they sit squarely on the international fan’s radar. EuroLeague in particular pulls in many of the same stars you will have just watched in the World Cup qualifiers, making the autumn a seamless handoff from country to club.

How to follow the action

FIBA’s official platforms remain the most reliable home for live scores, standings and detailed box scores across all the national-team and 3×3 events listed above. Many windows and tournaments are also distributed through regional broadcasters and FIBA’s own streaming service, so checking your local listings ahead of each window is worth the few minutes it takes.
