Mystics vs Fever combo

Over 177.5

Mystics +7.5

Georgia Amoore 2+ threes

Kelsey Mitchell 4+ threes

Washington leads the W with a 26-15 ATS record, ranking second at 13-8 on the road. Both matchups this season were decided by two points, and the Mystics can keep things close with their multi-layered scoring attack and strong defense.

Over the last seven games, Kelsey Mitchell leads the W in 3-point makes per game at 4.3, and Georgia Amoore ranks fourth at 3.3. Amoore shot 48.9% and cleared her triples line six times, while Mitchell shot 57.7% and cleared her line five times.

Fire vs Sparks combo

Sparks moneyline

Over 175.5

Rae Burrell 15+ points

The Sparks won't mind tonight's battle turning into a shootout — like their 106-101 victory in Portland last month. With no playoff implications on the line, expect both offenses to take off here, and the Over is 11-9 this year when the Fire are road underdogs.

Plus, L.A.'s frontcourt injuries should mean easier looks for the Portland guards when they drive into the paint.

I'm also banking on Rae Burrell to deliver an efficient scoring night. The Sparks' injury list will likely create more shots for Burrell and Ariel Atkins, and Ogwumike can't do all the scoring alone. Burrell has gone past this points O/U number in six of her last nine games.

Storm vs Aces combo

Jackie Young 20+ points

Aces -15.5

Under 175.5

The Aces are still jockeying for playoff position, so they won’t take their foot off the pedal. The Storm have scored 80 points or fewer in five of their last six games, covering the spread only twice in that span. Seattle ranks 14th in road scoring at just 79.5 ppg, while LV has averaged 89.7 at home.

The Storm have multiple key injuries and sport the worst record in the W. They’re surely focused on the future with no motivation to play competitively. I’ll play the Aces to 16.5 and bet the Under down to 170.5.

How to trade WNBA combos today

Kalshi users can combine predictions for various markets for every WNBA game! Moneylines, spreads, and totals are fair game, as well as props for a player’s total points, assists, rebounds, 3-pointers made, and combo markets.

Prediction markets like Kalshi will set a projected total number for all the traditional markets and player stats, and users can predict whether the team will win/cover, if the total will go Over/Under, or whether players will reach certain statistical thresholds or not.

Combining predictions can increase a potential payday, but it also increases the risk level. If even one prediction in a three-leg combo is wrong, the whole thing is graded as a loss.

What is Kalshi?

Kalshi is a federally regulated platform for trading event outcomes on prediction markets. Traders can buy and sell simple, transparent contracts that settle based on the outcome of real-world events. Markets revolve around a yes/no proposition, with prices adjusting dynamically based on traders’ perceived probability that the event will occur. When the event concludes, if you are correct, the contract “honors” at a predetermined price; if you are incorrect, it expires at $0.

Kyle’s biggest tip for any bettor is simple: gamble responsibly. Only bet what you’re willing to lose and make sure to install a proper bankroll method to keep track of your ROI. If you’re still dwelling on the amount you lost the next day, it’s time to decrease your spending.
