Jessica Pegula vs. Marta Kostyuk Prediction, Odds, Best Bets & How to Watch
Fourth seed Jessica Pegula meets 16th seed Marta Kostyuk in a semifinal that looks far tighter than a typical No. 6 vs. No. 26 matchup. Both players navigated different paths to this stage at the Brisbane International, with Pegula stabilizing after early pressure and Kostyuk knocking out two higher seeds in straight sets.
From a market perspective, this is a classic form-versus-floor question. Pegula’s 2025 numbers point to structural reliability with strong first-serve efficiency, elite return metrics, and consistent breakpoint conversion. While Kostyuk’s upside has been more volatile, especially following a wrist issue that forced late-season retirements last year. On hard courts, Pegula’s ability to absorb pace and reset rallies tends to translate into fewer service dips over extended matches.
The betting tension is whether Kostyuk’s aggressive ball-striking and recent Brisbane run justify her price compression. FanDuel keeps Pegula as a modest favorite, while BetMGM shades her slightly shorter. That gap signals respect for Kostyuk’s ceiling, but the market still prices Pegula as the more probable stabilizer over two or three sets.

Our Pick: Jessica Pegula moneyline (-154, BetMGM)
The market has this priced closer to a toss-up than the rankings suggest, largely due to Kostyuk’s Brisbane wins over Anisimova and Andreeva. However, Pegula’s underlying efficiency remains the differentiator. In 2025 she won nearly two-thirds of first-serve points while pairing that with top-tier return numbers.
From a risk perspective, the moneyline offers the cleanest exposure. Pegula has won four of the five head-to-head meetings and has repeatedly shown the ability to recalibrate mid-match against Kostyuk’s pace. The BetMGM price at -154 slightly overstates Kostyuk’s recent spike relative to her season-long inconsistency, making Pegula’s probability closer to the true median outcome than the spread or totals markets.
Pegula leads the series 4-1, with wins on both outdoor and indoor hard courts. While Kostyuk’s 2024 San Diego victory shows she can disrupt Pegula when dictating early. On a neutral hard court, that history remains relevant.
| Year | Winner | Event | Round | Score |
|---|---|---|---|---|
| 2025 | Jessica Pegula | Beijing | Round of 16 | 6-3, 4-7, 6-1 |
| 2025 | Jessica Pegula | Miami | Round of 16 | 6-2, 6-3 |
| 2024 | Marta Kostyuk | San Diego | Semifinals | 7-6, 6-1 |
| 2023 | Jessica Pegula | Australian Open | Round of 32 | 6-0, 6-2 |
| 2022 | Jessica Pegula | Cincinnati | Round of 32 | 6-7, 6-1, 6-2 |
Projection: Pegula wins in three sets
Higher-variance prop: Over 2.5 sets (+130, BetMGM). This carries added volatility but aligns with Kostyuk’s recent ability to steal a set before Pegula’s depth and return game take control late.
