North American Challengers League Summer 2026
Overview
The North American Challengers League (NACL) Summer 2026 is the second split of the 2026 season and the fourth year of Riot Games' official Tier 2 League of Legends circuit in North America. It serves as the primary developmental and "path-to-pro" league for the LCS (League Championship Series), the region's top professional league, providing a competitive pathway for independent and collegiate teams toward Tier 1 promotion opportunities. Organized by Riot Games and operated by Liga ACE Esports, the tournament is classified as an A-Tier event on Liquipedia. It features a $40,000 USD prize pool and is contested entirely online across North America (primarily the United States). The league succeeded earlier systems such as the LCS Academy and LCS Proving Grounds, emphasizing open competition for non-franchised and academy-affiliated organizations.
Liga ACE, a leading esports event operator in the Americas with experience in LATAM and North American circuits, handles production and operations. Official streams are available on Twitch (twitch.tv/NACL) and YouTube (@NACL). The series holds significant prestige within the North American LoL ecosystem as the main feeder system, with top performers qualifying for LCS promotion tournaments.
History
The North American Challengers League was introduced by Riot Games in late 2022 and launched in early 2023 as a restructuring of the region's Tier 2 ecosystem. It replaced the LCS Academy League (which required LCS organizations to field academy teams) and the LCS Proving Grounds (an open circuit for amateur and independent teams). The initial 2023 format featured 16 teams: 10 fixed academy teams tied to LCS organizations and 6 provisional independent/amateur teams.
Over subsequent years, the structure evolved. By 2024–2025, the league transitioned toward a more open model with 10 teams per split, reduced prize pools from earlier $100,000 USD highs to $40,000 USD per split, and a stronger emphasis on promotion/relegation and independent organizations, including strong collegiate programs such as Maryville University, Winthrop University, and University of Mississippi (Ole Miss). Partnerships for operations shifted; early seasons involved Rally Cry, while Liga ACE became a key operator by 2025–2026.
The 2026 season maintained a two-split format (Spring and Summer) aligned more closely with Tier 1 LCS scheduling. Key changes for 2026 included a revised group stage with cross-group matchups and continued integration of promotion tournaments. Cumulative prize money across NACL events has exceeded $660,000 USD. The league remains central to North American talent development amid broader Americas regional realignments.
Format
NACL 2026 Summer features 10 teams competing online. Teams are drafted into two groups of five, with the Spring 2026 grand finalists (Conviction and CCG Esports) serving as draft captains.
Regular Season (Group Stage): Single round-robin cross-group format. Each team plays every team from the opposite group once in best-of-three (Bo3) series. Matches run from July 16, 2026, onward.
- Top 3 teams from each group advance directly to Playoffs.
- Bottom 2 teams from each group enter a Last Chance Qualifier (LCQ).
Last Chance Qualifier: The 4th- and 5th-placed teams from each group compete. Matches are best-of-five (Bo5). Winners advance to Playoffs (bringing the total to 8 teams); losers face relegation risks via future promotion tournaments.
Playoffs: Double-elimination bracket with 8 teams. Exact seeding and series lengths (typically Bo3/Bo5 culminating in a Bo5 Grand Final) follow standard NACL conventions. Top finishers qualify for the LCS 2027 Promotion Tournament; lower placements secure spots in NACL 2027 or face promotion/relegation.
The full tournament runs from 2026-07-16 to 2026-09-17. Prize distribution (USD): 1st $12,000 (LCS 2027 Promotion), 2nd $8,000 (LCS 2027 Promotion), 3rd $6,400, 4th $4,000, 5–6th $3,200 each, 7–8th $1,600 each; 9–10th no prize money and relegation pathway.
Participating teams (as of mid-regular season) include NRG, University of Mississippi (Ole Miss, acquired Citadel Gaming slot), Maryville University, Conviction, Blue Otter, Cupid eSports (replaced Supernova), Dorado Gaming, Winthrop University, Contingent Esports (promoted), and CCG Esports. Roster changes and mid-season adjustments have occurred, such as player movements involving Dardoch and others.
Notable Editions
The 2023 inaugural season established the league with larger fields and higher prize pools ($100,000 per split), crowning Cloud9 Challengers (Spring) and Disguised (Summer) as early champions and validating the open model.
2024 editions featured strong academy and independent performances, with FlyQuest Challengers winning Spring and Dragonsteel taking Summer amid the shift away from mandatory academies. Luminosity Gaming dominated both 2025 splits, highlighting organizational stability before their later exit.
The 2026 Spring edition saw Conviction defeat CCG Esports 3–0 in the Grand Final to claim the title and $16,000, with Winthrop University finishing third. It set the stage for Summer with promotion/relegation drama, including Contingent Esports' promotion and Blue Otter's successful defense, plus slot acquisitions by collegiate programs. The ongoing 2026 Summer has featured competitive group play, with NRG undefeated early in Group A and Cupid eSports strong in Group B.
