This only resolves YES if the player was banned because they participated in the freestyle chess event. (I didn't have enough space for a full title)

Background FIDE has issued a statement regarding participation in Freestyle Chess events and their relationship to official FIDE tournaments, which contains the following language:

attempts by FCPC to present their project as a World Championship are in contradiction with the well-established status of FIDE and its authority over world championship titles in all relevant variations of chess

...

As the 2025-2026 World Championship cycle is underway, all qualified players are expected to sign an additional contract, which will include a clause indicating that participation in any alternative world chess championships in any variation of chess not approved by FIDE (except for the Freestyle tour in 2025) would lead to their withdrawal from the two consecutive FIDE World Championship cycles.

Resolution Criteria This market will resolve YES if FIDE officially prohibits any player from participating in the 2025-2026 World Championship cycle specifically due to their participation in Freestyle Chess events. Otherwise, this resolves NO when the 2026 FIDE classical world championship ends. Determination of the reason for a ban/suspension will be based on official statements by FIDE. If no official reason is given, I will try to judge whether or not the player was banned due to participation in a freestyle chess event based on other reporting, and resolve accordingly.

I will not bet on this market.
