Both Chess.com and Lichess will qualify two players into the championship stage. From the Chess.com page:-
Championship [25-31 October 2022]:-
- Four qualified players join the four invited players.
- The players compete in a group stage, followed by the semifinals and finals
- Group Stage [...] The top-two players from each group advance to the semifinals
- Semifinals and finals [...] Players compete in four-game matches
Location: Qualifiers are played online on Chess.com [and Lichess], while the final is an over-the-board event in Reykjavik, Iceland.
The two Chess.com qualifiers have already finished. I'll save the details for another post.
