Kyrgios has long been a polarising figure in the sport, given his chequered history on and off the court.
The Australian has received multiple sanctions over the course of his career for inappropriate behaviour and fiery outbursts.
There have also been allegations of domestic violence and accusations of sexist comments.
Kyrgios pleaded guilty to assaulting an ex-girlfriend in 2023, then had to distance himself from controversial influencer Andrew Tate in 2024.
His recent comments about playing Sabalenka – witheringly questioning on one podcast if he would even have to “try 100%” to win – has led to concerns the event will fuel misogyny.
In a press release announcing the event, Kyrgios’ tone was markedly differently.
“When the world number one challenges you, you answer the call. I’ve got massive respect for Aryna; she’s a powerhouse and a true champion,” he said.
Sabalenka does not seem to think the match will have any negative impact on the perception of women’s sports, simply saying at the US Open she thinks it is a “cool idea”.
Catherine Whitaker, co-host of the Tennis Podcast, believes the opposite.
“I see absolutely nothing to be gained for women’s tennis – I see only bleakness,” she told BBC Sport.
“It’s a crass commercial venture and a vehicle for one of the most outspoken misogynists in tennis who just wants attention.
“If Sabalenka wins, she beats a man who is unfit and has been a total irrelevance for a number of years. What does she win? Nothing. Unless she wins 6-0 6-0, people will only find ammunition to fire at women’s tennis.
“If Kyrgios wins, he and others of the same mind will claim it legitimises everything he’s already spewing out. It’s disgusting to be giving him a platform.
“I find it utterly ludicrous this is going to be happening in 2025.”
