Rainbow Six Siege added to Esports Nations Cup

The Esports World Cup Foundation (EWCF) has revealed that Rainbow Six Siege will join the inaugural Esports Nations Cup (ENC) 2026 line-up of competitive titles.

The tournament will debut in Riyadh, Saudi Arabia, from November 18th to 22nd, 2026, where 24 national teams will compete to be crowned the event’s first champion.

Out of the 24 teams competing in the Rainbow Six Siege esports tournament, 12 will be directly invited based on the Siege National Team Ranking, 10 will have earned a spot through the regional online qualifiers, and the last two will come from Wildcard slots.

The Siege National Team Rankings are shaped by the official Six Invitational point standings in addition to the results of the Rainbow Six Siege tournament at the Esports World Cup. National rankings will then invite the top five players to form a national roster, with the cut-off point set for May 17th.

The qualifiers will take place from May 29th to 31st, 2026. They will include a double-elimination bracket, and will be held in North America, South America, Europe, MENA (Middle East and North Africa), and Asia, offering two slots each.

The national teams will compete across two stages. The Group Stage will divide teams into four groups of six, competing in a round-robin format. The Playoffs will see the top 16 teams play in a single-elimination bracket.

All Group Stage matches will be best-of-one, with Playoff matches featuring best-of-three, and the Grand Finals will end the tournament with a best-of-five showdown.

Rainbow Six Siege is the latest title to join the ENC, a global esports competition that gathers the best players across multiple games to represent their nation.

Since the EWCF first unveiled the event last year, various esports and gaming brands have partnered with the event to bring the inaugural esports competition to life, welcoming brands such as EA, MOONTON, Krafton, Ubisoft and more.

In addition to Rainbow Six Siege X, other titles revealed recently include Chess, Trackmania, Mobile Legends: Bang Bang, and more. In total, 16 titles are expected to feature at the ENC, which runs from November 2nd to 29th, 2026.
