The US Open Women Singles quarterfinals feature a blockbuster clash today as No. 4 Coco Gauff takes on No. 5 Mirra Andreeva at 12:30 p.m. ET on Arthur Ashe Stadium court. I am circling this matchup because it pits a proven chalk favorite against an ascending underdog.
The single most important question for bettors is whether Andreeva can finally hold serve consistently enough to crack the American’s elite defense. Determining if Andreeva has closed that gap is the key to unlocking the betting value in this high-stakes showdown. Keep reading for the top predictions, picks and odds for Gauff vs Andreeva on Sep 9, below.
Odds for Gauff vs Andreeva Odds
Odds via Kalshi (moneyline, total) and Polymarket (spread) as of Sep 9.
Gauff will come into this match as a -186 moneyline favorite, while laying 2.5 games on the spread. Andreeva comes back as a +178 underdog, while the total varies depending on where you wager.
Predictions for Gauff vs Andreeva
Coco Gauff Moneyline (-186 at Kalshi)
I am laying the juice on the favorite here. Kalshi’s 65¢ Yes price converts to -186, a fair reflection of Gauff’s dominant 5-0 head-to-head record and matchup edge. Claim the Kalshi promo code today to tail this wager.
My confidence stems from Gauff’s relentless return pressure. During their May 2026 clash in Rome, Gauff generated a massive 17 break point opportunities, converting seven of them. Andreeva logged just three aces alongside six double faults in that match. Since Andreeva lacks the raw serving power to push her opponent back, Gauff should have ample chances to attack the second serve. At -186, I am confidently backing Gauff to advance.
Picks for Gauff vs Andreeva
Over 21.5 Games (-113 at Polymarket)
Over 22.5 games is priced at 46¢ Yes on Kalshi, which converts to +117 odds. However, you can play a full game lower at Polymarket for a reasonable -113 price. Get the Polymarket bonus code to lock in this line.
While Gauff holds the historical edge, Andreeva’s baseline game has proven capable of closing the gap. That makes the Over more appealing than laying Gauff -2.5 games at -133.
H2H History for Gauff vs Andreeva
Their last meeting was a grueling 4-6, 6-2, 6-4 battle where the margins were razor-thin. Gauff won 102 total points to Andreeva’s 95. More importantly, Andreeva proved she can consistently threaten Gauff’s serve, converting five of her 12 break point chances. With both women fighting for a Grand Slam semifinal berth, expect a volatile, drawn-out battle that eclipses this total.
Gauff’s 5-0 head-to-head record provides a massive psychological advantage, but bettors cannot blindly trust the sweep. Their recent matchups show a clear trend: Andreeva is figuring out the geometry of the court against the American.
During their latest clash, Andreeva pushed the match to a decisive third set. While Gauff’s break-point conversion ultimately sealed the deal, the tightening scorelines indicate this rivalry is becoming far more competitive. I weigh Gauff’s historical dominance heavily, but the recent data screams that an easy straight-sets blowout is highly unlikely.
