Qualification
On July 25, FIDE announced a preliminary list of 100 confirmed participants. FIDE also stated that the finalized lineup was expected to be available in September and was expected to have 114 players.

Under FIDE regulations, the initial 114 invites were distributed as follows:


 * 100 qualifiers by rating - the top 100 players in the FIDE rating list of 1 June 2023
 * The Women's World Champion as of 31 December 2022 (Ju Wenjun)
 * 4 continental spots, each nominated by one of the four FIDE continental presidents
 * 4 players nominated by the FIDE president (including a player who reached the final 16 of the World Cup, and the highest rated player who is not yet qualified)
 * Up to 5 players nominated by the organizer (Isle of Man International Chess Limited)

Various methods were also specified to replace a player who declined an invitation.

Results
Notation: "0 (B 70)" indicates a loss (0 points) with black pieces (B) against the player who finished 70th (Erwin l'Ami). The first tiebreak (labeled AROC-1) is the average rating of opponents "cut 1" (viz. excluding the lowest-rated opponent), which was sufficient to determine the qualifiers.
