The New York Liberty visit the Chicago Sky on Tuesday night at Wintrust Arena looking to continue a strong August run after beating Connecticut 82-75 on Saturday. That victory gave New York eight wins in its last 10 games. The Liberty have already beaten Chicago twice this season, but neither matchup was comfortable, with New York escaping 96-95 on June 17 and 95-94 on July 22. Chicago enters off a 97-88 loss to Seattle and will again try to lean on Kamilla Cardoso and its interior size against Jonquel Jones and Breanna Stewart.
New York’s biggest question is its health, with Satou Sabally sidelined and Sabrina Ionescu dealing with a foot injury that kept her out of Saturday’s win over Connecticut. Given how closely the Sky have played the Liberty in both previous meetings, Tuesday’s third matchup could be considerably tighter than the teams’ records suggest.
The narrow margins in the first two meetings suggest Tuesday’s matchup could be tighter than the standings imply. Polymarket’s prices offer another look at how traders are assessing the Liberty’s edge, the point spread, the total and several key player props before tipoff.
Polymarket WNBA: Liberty vs. Sky
Polymarket prices for Tuesday night’s New York Liberty vs. Chicago Sky matchup show New York as the clear favorite, while the spread and total markets point to a somewhat more competitive game than the moneyline alone might suggest.

The strongest signal comes from the moneyline, where New York is priced at 63¢. That gives the Liberty a clear edge in the market, although the difference is less pronounced against the spread. New York -4.5 is trading at 54¢, suggesting traders see a reasonable chance that the Sky can stay within the number even if the Liberty win outright. The total is essentially a coin flip. That lack of separation indicates little market conviction on the expected scoring environment entering the matchup. Player scoring markets are also fairly balanced around several posted totals.

Dimers’ simulation model leans toward New York, projecting the Liberty to beat the Sky 92-88 after running the matchup through 10,000 simulations. The model gives New York a 62% chance to win compared with 38% for Chicago, but the projected four-point margin is especially important with the Liberty laying 4.5 points. A competitive game would also fit what these teams have produced so far this season. New York is 2-0 against Chicago, but both wins came by a single point, 96-95 on June 17 and 95-94 on July 22. With Dimers projecting another close finish, the Liberty look more likely to escape with the outright win than to pull away comfortably.
Best Bet: Sky +4.5
Our best bet for this ballgame is Chicago Sky +4.5. New York has controlled this matchup in the standings, but Chicago has been the better side against the number. The Sky are 19-15 ATS overall this season, while the Liberty are just 12-24 ATS. New York has been particularly costly on the road, going only 3-15 ATS away from home and 1-11 ATS as a road favorite. Chicago is also 12-10 ATS as an underdog. The head-to-head results reinforce the play. Although the Liberty are 2-0 straight up against Chicago in 2026, the Sky covered comfortably in both meetings, getting +10.5 in a 96-95 loss in June and +7.5 in a 95-94 loss in July. With Dimers projecting only a four-point New York win, taking Sky +4.5 provides a small cushion in a matchup that has already produced two one-possession finishes.

New York deserves favorite status after winning both previous meetings, and Dimers’ simulations project the Liberty to make it three straight with a 92-88 victory. Still, Chicago’s season-long ATS advantage, New York’s poor road-covering record and two one-point head-to-head results make Sky +4.5 the more appealing spread play. Polymarket traders can also follow the matchup through moneyline, spread, total and player-prop markets as prices continue to adjust before tipoff.
