Sparks vs Wings prop: Jessica Shepard 15+ points
Jessica Shepard has an even bigger runway to take off in the Wings' final regular-season matchups with Fudd sidelined and Smith's return unclear.
With Paige Bueckers pulling the strings, there should be some easy looks for the Dallas Wings veteran.

Mercury vs Fire prop: Alyssa Thomas 9+ assists
Alyssa Thomas has been one of the best playmakers in the WNBA this season, averaging 8.4 assists per game to go along with 14.2 points and 7.7 rebounds. When the Phoenix Mercury offense is working, it goes through Thomas, who has picked up at least nine assists in five of her last six games.
The last time Thomas faces off against Portland she nearly compiled a triple-double, an effort that included dishing out nine assists. The Portland Fire allow opponents to tally more assists per game (23.0) than any team in the WNBA, and Thomas will take full advantage of that tonight.

Aces vs Storm prop: A'ja Wilson Over 9.5 rebounds
The Seattle Storm have surrendered the second-most rebounds to opponents (36.4), and they sport the third-worst defensive rebound percentage (66.3).
A'ja Wilson has corralled 10+ rebounds in nearly half of her 37 games (18 times), and she reached that mark in her lone matchup with the Storm.
Ezi Magbegor’s season-ending ACL injury cuts Seattle’s frontcourt depth. Seattle leads the W in pace and FGA across its last 10 games, offering increased rebounding chances for Wilson.
I’ll trade this one to 50%.

How to trade WNBA player props today
Player props allow WNBA fans to trade on a player’s total points, assists, rebounds, 3-pointers made, and a number of individual statistics like combo markets.
Just like standard Over/Under odds, prediction markets like Kalshi will set a projected total number for those stats, and traders can predict whether the player or team will have Over or Under that total.
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.
