Riftbound Regional Championships 2026 Guide

Riftbound's first competitive year ends with its biggest events yet: two Regional Championships, each worth a reported US$50,000, each sending its Top 8 to the first Riftbound World Championship in 2027. This guide covers both: dates, who can play, prize money, what format to expect, and which decks are likely to be at the top tables now that Radiance is legal.

The two Regional Championships at a glance

Some coverage mentions a separate Chinese Championship. China runs its own circuit through publisher Shining Soul, with its own National Opens, so check the Chinese schedule separately if you play there.

Who can play

The Regional Championships are invitation only. You earned an invitation by finishing in the Top 64 of a 2026 Regional Qualifier. The last RQ of the year was Los Angeles on 25–27 September, a 2,165-player event, so the list is now closed. Invited players pick which Championship to attend, which is why some North American players are expected in Stuttgart and some Europeans in Las Vegas.

If you missed the RQ circuit, the route back in is 2027: Riot has said more on the 2027 organized play structure will follow its State of the Game updates. In the meantime, Showdown Series events (Sacramento on 23–24 October, Orlando on 30 October–1 November) and your store's Nexus Nights and Summoner Skirmish windows are where the competitive scene plays week to week. Radiance's first Skirmish window opens on 9 November.

Prize money and the road to Worlds

Stuttgart's reported structure pays US$10,000 to the winner and US$250 to each of 33rd–64th place. Riot had not published every payout in between when we wrote this; one outlet reports US$5,000 for second place, but we have not seen that confirmed. Assume Las Vegas pays on a similar scale until Riot says otherwise.

The bigger prize is the World Championship invitation for the Top 8. Riot has confirmed the first Riftbound Worlds for 2027 but not its date, venue or prize pool. Given League of Legends' Worlds is the most-watched esports event in the world, expect Riot to stage it as a showpiece rather than a convention side hall.

The format: Standard, with Radiance two weeks old

Radiance launches on 23 October, so it is legal in Standard for both events. That gives players about two weeks of Radiance before Stuttgart, and seven before Las Vegas. Expect Stuttgart to reward whoever reads the new set fastest, and Las Vegas to look more settled.

Three rules changes matter:

• Radiance's Core Rules patch notes and errata take effect on 16 October. Our errata summary lists every changed card.
• The September 18 ban list removed Ekko, RecurrentUS$0.40 and Stacked DeckUS$0.20 from Standard and 2v2. The full ban list is kept current.
• The new keywords: Deploy, Show Off and Disarm. If you haven't played with them, start with the Deploy guide, then Show Off and Disarm.

The decks to beat coming in

The last major events before Radiance give us a starting picture:

• Los Angeles Regional Qualifier (25–27 September, 2,165 players): won by DSG Prismaticism on Rengar, PridestalkerUS$0.20, 14-0-2 and the only undefeated record in the Top 32, beating Irelia, Blade DancerUS$0.24 2-1 in the final. The Top 8 had two Azirs, two Irelias, and one each of Master Yi, Akali and Ornn.
• Chengdu National Open (October, 1,835 players): won by Azir, Emperor of the SandsUS$0.25, with Vex and Nasus behind it.
• Riftbound Challenge Gdańsk (10 October, 489 players): won by Rengar again, 11-1-1.

That makes Rengar, Azir and Irelia the three Legends to plan around. All three are older-set Legends (Rengar from Unleashed, Azir and Irelia from Spiritforged), so the question for Stuttgart is which of them gains most from Radiance's cards, and whether a Radiance Legend can break into the top tier straight away. Our view, from the one-year hot takes: Azir wins Stuttgart.

You can see every printing of each contender on their champion pages: Rengar, Azir and Irelia.

How a Championship weekend works

If you've only played Nexus Nights, the scale of a Regional Championship is the main adjustment. The structure is the same as the Regional Qualifiers:

• Swiss rounds first. Every player plays every round, paired against opponents with the same record. Matches are best-of-three, and a draw is possible when time runs out, which is why records like Prismaticism's 14-0-2 in Los Angeles include draws.
• A cut to the Top 8. After the Swiss rounds, the Top 8 by record play single-elimination quarterfinals, semifinals and a final on Sunday. Those eight players are the ones who earn Worlds invitations, so a Top 8 finish matters more than the trophy itself.
• Decklist registration. You submit your 40-card main deck, rune deck, Legend and battlefields before the event and play exactly that all weekend. Check the registration deadline in your invitation email; with Radiance two weeks old, many players will be finalising lists the night before.
• Tiebreakers. Players on the same record are separated by their opponents' win percentages, so a loss in round one can still make the cut and a strong schedule helps.

Riot's tournament rules changelog for October 2026 sets the current penalties and procedures. Read it before you travel, especially the sections on deck checks and slow play, which are where most game losses at large events come from.

Radiance cards to test first

We don't know the Radiance meta yet and won't pretend to. But three groups of Radiance cards are the obvious first tests for Championship lists:

1. Deploy cards in Azir and Irelia shells. Deploy is Radiance's most common keyword (27 printings in our database), and both Legends reward having extra bodies on the board.
2. Disarm as an answer to Rengar. Rengar's lists lean on buffed and equipped units, which is exactly what Disarm punishes. If Rengar is the deck to beat, Disarm cards will be in sideboards.
3. The new Legends. Eight Radiance Legends are confirmed. History says one or two are tournament-viable straight away and the rest take a few weeks of testing. The Radiance card list has all eight with live prices.

Building a Championship deck without overpaying

A competitive Riftbound deck is not cheap, and the two weeks after a set launch are the most expensive time to buy one. Our price records show Vendetta's median single fell 56% between its first week and mid-October. That is no help if your event is in two weeks, but it changes how you should buy:

1. Buy the older-set core now. If you're on Rengar, Azir or Irelia, most of your deck is Unleashed or Spiritforged cards whose prices have settled. Compare them across stores in the market view and order early: international shipping takes longer than two weeks.
2. Buy only the Radiance cards you've tested. Launch-week Radiance prices will be the highest they get for most cards. Proxy them in testing where your store allows, then buy the few that make the list.
3. Use Best Basket. Best Basket splits a list across stores to find the cheapest total including shipping, which matters more for a 40-card deck than any single card.
4. Check your market. Prices differ a lot by country. Our country comparison shows where each card is cheapest.

Travel and timing notes

• Stuttgart: Messe Stuttgart is next to Stuttgart Airport, and the Friday start means most players arrive Thursday. The event runs six Swiss rounds on Friday, six more on Saturday, then a Top 8 cut, with quarterfinals through the final on Sunday.
• Las Vegas: Convergence Fest runs Riftbound alongside Teamfight Tactics, so expect a crowded hall and a strong side-event programme.
• Coverage: Riot streams its major events on the official Riftbound YouTube and Twitch channels and posts results, standings and decklists on @RiftboundOP on X. We will cover both Top 8s and what they mean for prices.

What happens after

The Regional Championships end Riftbound's first competitive season. Legacy previews follow (the set launches on 29 January 2027) and, after it, Riot's first State of the Game of 2027 in February, which is where we expect the 2027 RQ calendar and Worlds details. The 2027 set roadmap has every dated release, and the Radiance card list has every card that will be legal in Stuttgart.

One thing we're confident about: a strong result at a Regional Championship moves prices. When a Legend wins a big event, its key cards tend to rise in the following days. Set a price alert on any card you're planning to buy before the weekend of 6 November.
