Aryna Sabalenka faces Marta Kostyuk in the Brisbane WTA final on hard courts on 11 Jan 2026, a best-of-three showdown with the trophy and early-season momentum on the line. We'll break down the match-up and explain how to watch or follow it live.
It is only the second week of the 2026 season, so the numbers come with a health warning. Even so, the market and the head-to-head point firmly one way, while Kostyuk's run to the final has been one of the surprises of the tournament.FINISHED
Sabalenka A.

6-4
, 6-3
Sabalenka leads this match-up 4-0, with three tie-breaks all going her way. Their most recent meeting came at the French Open on 28 May 2023, when Sabalenka won in straight sets, and the broader pattern has been similar: she has held serve more securely and turned more break chances into games, which has kept Kostyuk chasing at key moments.

Both players are 4-0 on hard courts this season, but it is still very early in the calendar and the sample is thin. Sabalenka's hard-court figures stand out for their sharpness, winning 100% of service games and 83% of return games, while Kostyuk's clearest early marker is a 59% break-point conversion and slightly longer matches on average at 16.4 games to Sabalenka's 13.6.

Over their last 10 matches overall, both come in at 8-2, so the form line is tight. Sabalenka has generated more free points with 6.1 aces per match and kept her error rate down at 1.8 double faults, and she has won the opening set 90% of the time; Kostyuk's 57% break-point conversion hints at her ability to apply pressure, but her deciding-set win rate sits at 33% compared to Sabalenka's 67%.

Bookmakers price Sabalenka at 1.33 against Kostyuk at 3.4; the first-set prices are 1.44 versus 2.75. That gap reflects the wider profile, even with the reminder that Kostyuk has already outperformed expectations by reaching this final.
Sabalenka arrives as the top-ranked player and with a clean head-to-head, and that tends to simplify the picture when the pressure rises. Still, this is the season's second week and both have played back-to-back matches, with Kostyuk logging 8 hours 37 minutes across her last five compared to Sabalenka's 6 hours 57, which may matter if the final turns into longer exchanges. If Kostyuk can keep taking her chances on return, she can make it uncomfortable, but Sabalenka's recent first-set rate suggests she often grabs control early.
Prediction
Aryna Sabalenka
Marta Kostyuk
Overall indicators tilt towards Aryna Sabalenka: the 1.33 price and a 4-0 head-to-head both point to her handling the match-up well under pressure. Marta Kostyuk's run to the final has been a genuine surprise and the season is still in its second week, but Sabalenka's stronger recent first-set record and the cleaner track record in tie-break moments make her the likelier winner.
