The 2026 World Star Challengers Invitational is bringing Tier 2 League of Legends teams from China, Korea, APAC, the Americas and EMEA together for the first time on a global stage. Announced by Riot Games on September 3, WSCI will run from September 20 through October 2, giving developing teams an international competition built around player development and cross-regional play.
The first World Star Challengers Invitational will bring together 16 Tier 2 teams from across China, Korea, APAC, the Americas and EMEA. Riot Games and TJ Sports are behind the event, with three teams coming from each region and the Asia Masters champion taking the final place.
What is the 2026 World Star Challengers Invitational?
The 2026 World Star Challengers Invitational, or WSCI, is a new international tournament for Tier 2 League of Legends teams. It will give developing rosters their first chance to compete against teams from other regions, rather than staying within their usual domestic competition.
Riot describes WSCI as a pilot for international Tier 2 competition. The event is intended to strengthen the competitive pathway below the top professional level while exposing players to different strategies, playstyles and competitive environments.
The tournament also builds on the existing Asia Masters structure rather than creating an entirely separate competition from scratch. The resulting field combines teams from five LoL Esports regions with the Asia Masters champion.

2026 World Star Challengers Invitational dates and tournament schedule
The first WSCI will be held from September 20 through October 2. The group stage will feature the entire 16-team field, while only eight teams will advance to the knockout stage.
| Stage | Dates | Format | Teams |
|---|---|---|---|
| Group stage | September 20-25 | Double round robin, best-of-one | 16 |
| Knockout stage | September 27-October 2 | Single elimination, best-of-five | 8 |
| Final | October 2 | Best-of-five | 2 |
How the WSCI 2026 format works
Four groups of four will make up the opening stage. Every team will play each of the other three teams twice, with six group-stage matches for each side. All of those matches will be best-of-one.
The group stage runs from September 20 to 25 and will feature 48 matches across six days, with eight games played each day. The top two teams in each group will move on to the playoffs.
Eight teams shall progress to the knock-out phase starting on September 27. The quarterfinals, semifinals, and the final all shall adopt the best-of-five system and the competition shall be completed by October 2.
What happens in the group draw?
The 16 teams will be split between three seeding pools. Each group will then draw one team from Pool 1, one from Pool 2 and two from Pool 3.
The draw also includes regional restrictions. Teams from the same region that are represented in Pools 1 and 2 cannot be placed in the same group, while no group can contain more than two teams from a single region. The rules are designed to create a more varied international group stage.
Which regions and teams are playing at WSCI?
WSCI will feature representatives from five LoL Esports regions: China, Korea, APAC, the Americas and EMEA. Each region will use its own qualification pathway to select three participating Tier 2 teams.
| Region | Teams | Qualification |
|---|---|---|
| China | 3 | Regional qualification |
| Korea | 3 | Regional qualification |
| APAC | 3 | Regional qualification |
| Americas | 3 | Regional qualification |
| EMEA | 3 | Regional qualification |
| Asia Masters | 1 | Asia Masters champion |
| Total | 16 |
Those 15 regional qualifiers will be joined by the Asia Masters champion, completing the 16-team field.
The tournament therefore offers a rare opportunity to compare developing teams from different competitive ecosystems. Instead of remaining within regional competition, players will have to adapt to opponents and approaches they may not regularly encounter at home.
How to watch the 2026 World Star Challengers Invitational
WSCI matches will be available through regional Tier 2 social channels, with regional co-streamers also expected to bring the tournament to audiences around the world.
Riot has not positioned WSCI around one single global broadcast channel in its announcement. Viewers should therefore keep an eye on the relevant regional Tier 2 channels and official LoL Esports accounts as the September 20 start approaches.
The official LoL Esports announcement contains Riot's full explanation of the tournament format and its goals for Tier 2 competition.
Why WSCI matters for Tier 2 League of Legends
Tier 2 is an important part of the League of Legends competitive pipeline. It provides a development environment for emerging players, gives organizations a place to invest in future talent and helps connect the amateur level with professional competition.
For many of these teams, WSCI will be their first chance to play against opponents from outside their region. That means preparing for teams they have never faced before, with different ideas about how the game should be played. For the players, it is a chance to see how they stack up internationally and get used to playing in a bigger tournament.
That is particularly significant for players attempting to establish themselves as future professional stars. International exposure cannot guarantee promotion to a top-level roster, but it can give developing players and teams a more demanding environment in which to demonstrate their ability.
What WSCI could mean for the future of LoL Esports
Riot is treating the 2026 tournament as a pilot rather than presenting it as a finished model for international Tier 2 competition. The results and experience from WSCI are expected to help inform how cross-regional competition could support player development in the future.
The experiment also gives regional ecosystems a chance to build stronger connections. For organizations, the event can provide a benchmark for how their developing rosters compare internationally. For players, it offers an opportunity to compete outside the familiar regional environment.
How well WSCI works could determine whether international Tier 2 events become a regular fixture.
