Las Vegas is the 74c favorite on both Kalshi and Polymarket, an identical quote on each book, after trading at 23c as a road underdog at New York on August 9 in a game the Aces lost 111-71. That 51c repricing in 48 hours is the venue and very little else: Las Vegas (22-11) plays at home for the first time since July 31, while Washington (19-12) arrives with a six-game winning streak that was built entirely in Washington. The live board above carries the full spread and total ladders.
The Washington Mystics vs Las Vegas Aces market is pricing a building, not a form curve. Las Vegas sits at 74c on both Kalshi and Polymarket after being quoted 23c as a road underdog at New York on August 9, a game the Aces lost 111-71. Washington is 26c despite carrying a six-game winning streak into the trip. That 51c repricing inside 48 hours is the largest venue-driven swing on the WNBA board for August 11, 2026, and the moneyline has held flat at 74c and 26c on both books since the market opened.
Las Vegas is 22-11 and Washington is 19-12. A three-game gap in the standings does not on its own justify a 48c spread on the moneyline, so the venue is doing the work. The Aces play at Michelob ULTRA Arena for the first time since July 31, when they beat New York 104-99, and they arrive off a five-game road stretch that produced a 2-3 record and closed with back-to-back losses at Minnesota (98-87) and at New York (111-71).
The counterweight to the home-court read is the Aces' own splits. Las Vegas is 13-6 on the road and 9-5 at home this season, one of the few teams whose away record is the better of the two. The market is paying up for a home edge that Las Vegas has converted at a lower rate than its road results all year.
Washington's streak is the mirror image. All six wins came at home: 100-99 over Las Vegas on July 22, 92-84 over Connecticut, 81-75 over Dallas, 96-92 over Dallas, 79-74 over Atlanta, and 95-75 over Phoenix on August 9. The Mystics are 11-6 at home and 8-6 away, so the streak and the road record point in opposite directions. The July 22 head-to-head is the single most relevant data point on this board, and Washington took it by one point.
The personnel matchup runs through A'ja Wilson, who averages 26.3 points, 9.7 rebounds, 3.1 assists and 2.0 blocks per game and sets the Aces' team total. Chelsea Gray runs the offense at 7.1 assists per game. Washington answers with Sonia Citron at 17.1 points and 3.8 assists and Shakira Austin at 16.2 points and 9.6 rebounds, the rebounding number that matters most against Wilson.
Cross-platform, there is nothing separating the two books. Kalshi and Polymarket both quote Las Vegas at 74c and Washington at 26c, a 0c gap on each side of the moneyline, so the pricing differences on this game live in the spread and total ladders rather than the headline number. Board volume is roughly $44.8K, and the flow is lopsided by contract: the Washington moneyline contract carries about $28.3K in lifetime volume against about $8.7K on the Las Vegas side.
The Kalshi spread ladder prices Las Vegas -1.5 at 73c, -3.5 at 66c, -6.5 at 57c, -9.5 at 45c, -12.5 at 36c, -15.5 at 29c and -18.5 at 22c. The 50% crossover falls between -6.5 and -9.5, implying a fair line near Las Vegas -7.5. Polymarket lists Las Vegas -7.5 directly at 53c, which agrees with the Kalshi ladder and with the sportsbook consensus number of -7.5. Flipping sides, Washington -1.5 is 25c, -3.5 is 20c, -6.5 is 13c and -9.5 is 10c.
The total is equally coherent across books. Kalshi runs Over 154.5 at 82c down to Over 178.5 at 27c, with the crossover between Over 166.5 (54c) and Over 169.5 (46c). Polymarket quotes the 167.5 total at 51c and the 168.5 total at 47c. Both books land on roughly 167 to 168 combined points, matching the consensus total of 167.5. For scale, Washington's last game finished at 170 combined points and the Aces' last game finished at 182.
The derivative markets are thinner. The first-half spread prices Las Vegas by more than 7.5 at the half at 45c and Washington by more than 1.5 at the half at 44c. On player props, the only line carrying a live quote is Shakira Austin assists at the 2.5 number, 48c on Polymarket. The A'ja Wilson points ladder at 24.5 and rebounds at 9.5, plus the Jackie Young, Kiki Iriafen and Chelsea Gray props, are listed without prices, so they carry no market read yet.

The Aces board from August 9 at New York is the direct comparison for how far this line has traveled, and the Mystics board from the same night against Phoenix shows the market that Washington's 95-75 win came out of. Season-long context lives on the Las Vegas Aces hub and the Washington Mystics hub, and the full slate plus championship pricing sits on the WNBA prediction markets hub.
This market resolves to the team that wins the game between the Washington Mystics and the Las Vegas Aces at Michelob ULTRA Arena in Las Vegas on the night of August 11, 2026. The winning team's moneyline contract settles at $1 per share and the losing team's settles at $0. There is no draw outcome in the WNBA, so any tie at the end of regulation is decided in overtime and the overtime result is the settled result. Spread contracts settle on the final margin including overtime, total and team-total contracts settle on final combined or team points including overtime, and first-half contracts settle on the halftime score alone. If the game is postponed and replayed, both platforms settle on the rescheduled result under their published rules; if it is canceled outright and not replayed inside each platform's stated window, the contracts void and refund per that platform's cancellation policy.
As of August 11, 2026, Las Vegas is 74c on both Kalshi and Polymarket and Washington is 26c on both books. That is an implied 74% to 26% split with a 0c cross-platform gap on the moneyline.
Las Vegas is favored at 74c, an implied 74% win probability, despite losing 111-71 at New York two nights earlier. The spread ladder crosses 50% near Las Vegas -7.5.
Kalshi and Polymarket both list the game. Kalshi carries the deeper ladder with moneyline, spread, total, team-total and first-half contracts; Polymarket lists the moneyline, a Las Vegas -7.5 spread at 53c and the 167.5 and 168.5 totals.
The consensus line is Las Vegas -7.5 with a 167.5 total. Kalshi prices Las Vegas -6.5 at 57c and -9.5 at 45c, and Over 166.5 at 54c against Over 169.5 at 46c, so both ladders cross 50% at those numbers.
It resolves on the final score of the game at Michelob ULTRA Arena on the night of August 11, 2026. Both Kalshi and Polymarket settle once the result is official, typically within hours of the final buzzer.
Watch whether the 74c line holds into tipoff after the Aces' 111-71 loss on August 9, and watch the player props, where only Shakira Austin assists at 2.5 (48c on Polymarket) carries a live quote as of August 11, 2026.
