World No. 1 tennis player Aryna Sabalenka said top players may boycott Grand Slam tournaments if their demands for increased revenue sharing are not addressed, marking an escalation in an ongoing dispute between players and tournament organizers.

Speaking at a press conference during the Italian Open, Sabalenka stated that a boycott may be "the only way to fight for our rights," suggesting tensions have reached a critical point in negotiations that have been ongoing for more than a year.

The dispute began in March 2023 when players sent their first formal letter to the four Grand Slam tournaments requesting a greater percentage of tournament revenues, contributions to player welfare initiatives including pension funds, and the establishment of a Grand Slam player council for closer consultation on tournament matters.

According to the player group, the Grand Slam organizers have not provided substantial responses to the first two requests regarding revenue sharing and welfare initiatives, leading to growing frustration among top players.

The four Grand Slam tournaments - Wimbledon, the US Open, French Open, and Australian Open - generate significant revenue through television rights, sponsorship deals, and ticket sales, though the specific financial details and current revenue-sharing arrangements were not disclosed in the players' public statements.
