Las Vegas is the 65c home favorite over New York on July 30, 2026, and both books print the identical number: Kalshi and Polymarket each have the Aces at 65c and the Liberty at 36c. The 101c sum leaves 1c of overround, so the vig-free read on Las Vegas is roughly 64%. The Aces are 19-8 and second in the West; the Liberty are 16-12, third in the East, and have won three straight, all by 4 points or fewer.
Las Vegas is the 65c home favorite for Thursday's meeting with New York, and the two books agree exactly: Kalshi and Polymarket each price the Aces at 65c and the Liberty at 36c. That 101c sum leaves 1c of overround, putting the vig-free implied win probability for Las Vegas at roughly 64%. The board carries about $29K in total volume across the moneyline, a spread ladder, a total ladder, and a Polymarket-only player prop stack, with the moneyline the deepest leg at roughly $5.7K on the Kalshi Aces contract and $4.9K on the Polymarket pair.
Las Vegas enters at 19-8 (.704), second in the Western Conference and 3 games behind Minnesota (23-6). The Aces are 8-5 at home and 11-3 on the road, have gone 7-3 across their last 10, and beat Portland 98-83 at home on July 29. They average 91.3 points on 49% shooting from the field and 36% from three, allow 86.2, and distribute 22.4 assists per game.
New York is 16-12 (.571), third in the Eastern Conference and 2 games behind Indiana (18-10). The Liberty have won three straight and every one was a one-possession finish or close to it: 99-98 in overtime at Dallas, 95-94 over Chicago, and 113-109 at Los Angeles on July 29. The longer sample is softer at 4-6 over the last 10. New York averages 89.4 points, allows 87.0, and shoots 46% from the field and 35% from three.
Both teams played on July 29, so this is the second night of a back-to-back for each. New York has the harder version of it, a road back-to-back that follows a 113-point game in Los Angeles, and that scheduling asymmetry is the cleanest justification for a 65c home price on a team the Liberty already beat in this building.
The spread ladder centers on Las Vegas -4.5 at 53c, matched on Kalshi and Polymarket, which is about as close to a coin flip as the board gets. Kalshi carries the full ladder around it: the Aces at -1.5 trade 59c, -7.5 trade 40c, -10.5 trade 28c, and -13.5 trade 21c. Polymarket adds an Aces -3.5 at 56c. Read together the ladder puts the median expected margin at 4 to 5 points for Las Vegas, which is internally consistent with the 65c moneyline rather than in tension with it.
The total sits at 181.5, priced 51c on Kalshi and 50c on Polymarket, a 1c gap. That number is almost exactly the sum of the two scoring averages (91.3 plus 89.4 equals 180.7). Kalshi runs an over ladder from 163.5 at 90c up to 187.5 at 37c, and Polymarket posts a 182.5 line at 47c. Nothing on either side of the total is off by enough to be a trade.
A'ja Wilson is the price. She is averaging 26.2 points, 9.7 rebounds, 3.0 assists, and 2.0 blocks on 53.7% shooting and 44.1% from three across 25 games, which is why she anchors the WNBA MVP market. Jackie Young (17.0 points, 6.6 assists) and Chelsea Gray (12.7 points, 7.3 assists, 40.3% from three) run the supporting offense.
New York counters with Breanna Stewart (21.4 points, 8.4 rebounds) and Jonquel Jones (14.6 points, 9.1 rebounds, 40.7% from three). Sabrina Ionescu has appeared in only 16 of 28 games and produces 15.6 points and 4.2 assists when available. Her Polymarket points line for this game is 18.5, nearly 3 points above her season average, and it is the most aggressive number in the prop stack. The rest of that Polymarket-only ladder sits tight to the season baselines: Wilson at 25.5 points and 9.5 rebounds, Stewart at 20.5 points, Jones at 8.5 rebounds, Young at 17.5 points, and Gray at 6.5 assists.
Availability cuts against New York. The Liberty are without Satou Sabally (concussion), Marine Johannes (ankle), and Leonie Fiebich (foot). Las Vegas is missing Kierstan Bell (leg), Cheyenne Parker-Tyus (concussion), and Janiah Barker (leg), with NaLyssa Smith listed day-to-day.
The case for the Liberty at 36c is the June result. New York won 87-76 at Michelob ULTRA Arena on June 23, 2026, holding Las Vegas 15 points under its season scoring average, and leads the season series 1-0 with the third meeting scheduled in New York on August 9, 2026.
On movement, the line has held with a small drift toward Las Vegas. The Aces have traded from 64c to 65c on Kalshi across the snapshot window, and the Liberty side on Polymarket has eased from a 39c high back to 36c. The sportsbook move was larger: DraftKings opened Las Vegas at -149 and now prices the Aces at -190, or 65.5% implied, which is precisely where both prediction markets already sit. ESPN's matchup predictor is the outlier at 59.3% for Las Vegas, roughly 5 points softer than the traded price.
The moneyline resolves to the team that wins the game at Michelob ULTRA Arena in Las Vegas on July 30, 2026, overtime included. Spread contracts settle on the final margin and total contracts on the combined final score, also including overtime. Both Kalshi and Polymarket settle once the game is official, normally within hours of the final buzzer.
The outcome here moves the seeding picture in both conferences, which trades on the WNBA No. 1 Seed market and further out on the WNBA Finals market. Wilson's individual case runs through the MVP board and the WNBA Defensive Player of the Year market, where her 2.0 blocks per game are the headline number. Every other WNBA game board and season future is indexed on the WNBA hub.
The moneyline resolves to the team that wins the New York Liberty at Las Vegas Aces game played at Michelob ULTRA Arena in Las Vegas on July 30, 2026, with overtime included in the final result. Each winning team contract pays $1 per share and the losing side resolves to $0. Spread contracts settle on the final margin of victory and total contracts settle on the combined final score, both including overtime. Kalshi and Polymarket settle from the official league box score once the game is final, normally within hours of the last buzzer. If the game is postponed, settlement moves to the rescheduled date; a game that is never completed voids under each platform's own rules.
As of July 30, 2026, Las Vegas is the 65c favorite and New York is 36c, with Kalshi and Polymarket printing identical prices on both sides. The spread is Las Vegas -4.5 at 53c and the total is 181.5 at about 50c.
Las Vegas is favored. At 65c against 36c the two-sided market carries 1c of overround, which puts the vig-free implied win probability for the Aces at roughly 64% and New York at roughly 36%.
Both Kalshi and Polymarket carry the game. Kalshi runs the deeper spread ladder from Las Vegas -1.5 through -13.5 and an over ladder from 163.5 to 187.5, while Polymarket carries the entire player prop stack including A'ja Wilson at 25.5 points.
It resolves after the game at Michelob ULTRA Arena in Las Vegas on July 30, 2026. Both platforms settle from the official final score, overtime included, normally within hours of the final buzzer.
The line has held with a small drift toward Las Vegas. The Aces traded from 64c to 65c on Kalshi and the Liberty eased from a 39c high to 36c on Polymarket, while DraftKings moved from an opening -149 on Las Vegas to -190.
NaLyssa Smith's day-to-day status for Las Vegas and any late New York availability news, since the Liberty are already down Sabally, Johannes, and Fiebich. A confirmed absence on either side would move the 65c number before July 30, 2026.
