Washington (23-15) is the 66.5c road favorite over the Los Angeles Sparks (13-25) at crypto.com Arena, 67c on Kalshi and 66c on Polymarket, with the Sparks at 34c on both books. The two exchanges opened this board 15c apart and have converged to within 1c over the last 24 hours of snapshots. The live board above carries the current moneyline, the full spread ladder around Washington -5.5, and the total near 167.5. Tip is 10:00 PM ET on Friday, August 28, 2026, and the market settles on the final score.
Washington is the second night of a back-to-back and the fourth and final game of a western road trip, and the market has been repricing that all day. The Mystics play at Phoenix on Thursday, August 27 at 10:00 PM ET, then land in Los Angeles for a 10:00 PM ET tip on Friday. The Sparks have not played since Monday, August 24, a 78-71 home loss to Atlanta, so this is rest against travel with a 10-game gap in the standings running the other way.
Washington sits 23-15 and fourth in the Eastern Conference, two games back of Atlanta (25-13) and level in the loss column with New York (23-15). The Mystics are 4-1 in their last five, including a 105-100 win at Portland on August 23 and a 94-84 win at Phoenix on August 25. Shakira Austin is carrying the interior at 16.9 points, 9.5 rebounds and 1.4 blocks per game, with Sonia Citron leading the team at 4.3 assists per game. Washington is 10-8 on the road, which is the number that matters on a trip like this one.
Los Angeles is 13-25 and sixth in the West, 17.5 games behind Minnesota, and the Sparks have lost seven of their last eight. The one win in that stretch was 77-68 over Connecticut on August 23. Nneka Ogwumike remains the offense at 16.8 points and 8.9 rebounds per game, with Erica Wheeler at 5.1 assists. The Sparks are 6-13 at home, a worse home record than Washington's road record, and that alone explains most of the two-thirds price on the visitor.
The season series is split. Los Angeles won 92-87 in Washington on May 29, and the Mystics answered 80-70 in the rematch on August 15. This is the third and final meeting and the first in Los Angeles, so the head-to-head data cuts against the idea that Washington should be a comfortable favorite here.
The spread ladder is where the disagreement lives. Kalshi prices Washington -6.5 at 48c, Washington -3.5 at 58c and Washington -1.5 at 62c, while Polymarket has Washington -5.5 at 51c and Washington -6.5 at 47c. Interpolating the Kalshi rungs puts a fair Washington -5.5 near 51c, so the two books are inside a cent of each other on the number the sportsbook consensus also settled on (Washington -5.5, moved from an opening -4.5). On the total, Polymarket shows 167.5 at 49c while Kalshi's Over 166.5 sits at 56c and Over 169.5 at 48c, which brackets 167.5 in the low 50s. Every part of this board agrees on the shape of the game.
The snapshot series on this board reaches back about 24 hours, so scope the read to that window. Kalshi opened Washington at 76c in the early hours of August 26 and has walked it down to 67c, a 9c move toward Los Angeles. Polymarket went the other way over the same window, from 61c up to 66c. The books started 15c apart and finished 1c apart at 67c and 66c, which is convergence on a thin board rather than one side taking a position. Lifetime volume across the whole game is roughly $1.3K, with $897 of it on the Mystics moneyline leg, so single tickets move these prices and the early Kalshi 76c should be read as a thin quote correcting rather than as real information leaving the market.
The moneyline resolves to the team that wins the game outright at crypto.com Arena on Friday, August 28, 2026, tip scheduled for 10:00 PM ET. Spread contracts settle against the final margin and total contracts against the combined final score, overtime included. Both Kalshi and Polymarket settle from the official WNBA final, typically within hours of the buzzer.
Washington's other leg of this trip trades on the Mystics vs Mercury board for August 27, and the outcome there sets the rest question for this one. For the season-long picture, the Sparks win total market prices a Los Angeles team that has one win in its last eight games, while the 2026 WNBA championship board and the Mystics win total track where a 23-15 Washington team lands in the East. Team pages for the Washington Mystics and the Los Angeles Sparks carry every open market on each club, and the WNBA hub lists the full slate.
The moneyline resolves to the team that wins the Washington Mystics at Los Angeles Sparks game at crypto.com Arena on Friday, August 28, 2026, scheduled for 10:00 PM ET. Each winning contract pays $1 per share and the losing side settles at $0. Spread contracts settle against the final margin of victory and total contracts against the combined final score, with overtime counted in both. Kalshi and Polymarket both settle from the official WNBA box score, normally within a few hours of the final buzzer. If the game is postponed and replayed on a later date, both platforms settle on the rescheduled result under their published game rules; if it is canceled outright and not made up, contracts void and refund.
As of August 27, 2026, the Washington Mystics are 66.5c on the moneyline for the August 28 game, 67c on Kalshi and 66c on Polymarket, with the Los Angeles Sparks at 34c on both platforms. That is an implied win probability of roughly 66% for Washington.
Washington is favored on the road. The Mystics are 23-15 and fourth in the Eastern Conference, the Sparks are 13-25 and sixth in the West, and the spread ladder centers on Washington -5.5 at about 51c on Polymarket.
