Aces vs. Valkyries Prediction: Game 1 Pick for WNBA Semifinals Showdown

The Las Vegas Aces and Golden State Valkyries open their WNBA Semifinals series on Sunday at Chase Center, and this one carries real stakes beyond just Game 1. Golden State finished the regular season at 32-12, good for the No. 2 seed in the West and the best home record in the league at 17-5 inside Ballhalla. Las Vegas, the three-time champion in the last four years, comes in as the No. 3 seed at 31-13 after grinding past the Indiana Fever in a three-game first-round series. Tip-off is set for 4 p.m. ET on NBC and Peacock, and both teams arrive with something to prove — the Valkyries are fresh off the first playoff series win in franchise history, while the Aces are trying to prove last year’s sweep of Phoenix for the title wasn’t a last gasp.

What the Betting Market Is Saying

Las Vegas opened as a slight favorite in most books, with the line hovering around Aces -1.5 and the total sitting at 161.5. That’s a notably tight number for a series opener between a three-seed and a two-seed, and it reflects how differently the regular season and the betting market are viewing this matchup. The Aces went a perfect 3-0 against Golden State in the regular season, winning by scores of 91-81, 84-79 and 92-73, which is clearly still weighing on oddsmakers despite the Valkyries holding the better overall record and home-court advantage.

Worth noting: Las Vegas also has the rest advantage here, having closed out its first-round series a day before Golden State finished off Dallas, and teams with that edge have covered at a strong clip in recent postseasons. Bettors looking at sportsbook promo codes ahead of tip-off will find plenty of options to get a position on either side of a spread that could easily tighten before the opening tip.

A Season Series Sweep Meets a New Playoff Reality

A’ja Wilson is the headline act for Las Vegas, and she has been nothing short of dominant this postseason. She led the WNBA in scoring during the regular season at 26.2 points per game and has somehow been even better in the playoffs, averaging 32.0 points per contest through the first round against Indiana. Wilson has already won three championships in the last four years, including a sweep of the Phoenix Mercury in the 2025 Finals, and she enters this series as the single biggest variable on the floor. Alongside her, Jackie Young has quietly been one of the most efficient guards in the league, averaging 18.9 points, 4.4 rebounds and 6.8 assists in the regular season before elevating to 23.3 points, 4.7 rebounds and 7.3 assists per game against the Fever, shooting better than 42 percent from three in the process.

Golden State counters with a deeper, more balanced attack built around veteran guard Tiffany Hayes, who is averaging 15.0 points, 2.7 rebounds and 2.7 assists this postseason while shooting an efficient 46.7 percent from the field and 50 percent from three. Forward Kayla Thornton, back from the knee injury that ended her 2025 season early, has settled into a starting role and produced 7.7 points and 3.7 rebounds per game in the playoffs, including a strong two-game stretch against Dallas where she combined for 23 points and 11 rebounds on the strength of five made threes. The Valkyries needed every bit of that contribution in the first round, erasing a 16-point deficit to beat the Wings in three games and claim the first postseason series win in franchise history.

The season series clearly favors Las Vegas, but close examination of those three meetings shows Golden State competing hard in two of them — the 84-79 and 92-73 results were played without the benefit of a true playoff atmosphere at Chase Center, where the Valkyries were the best home team in the WNBA this year. ESPN’s analytics model actually favors Golden State to win this specific game, projecting the Valkyries at better than 64 percent, and gives them a 64.9 percent chance of advancing to the Finals compared to 35.1 percent for Las Vegas. That’s a notable disconnect from the moneyline, where the two teams are priced almost dead even. This is a best-of-five series, so Game 1 matters, but it isn’t the whole story — Las Vegas has won Game 1 in nine of its last eleven postseason series dating back to 2022, a trend that still favors the champs even against a team that finished a game ahead of them in the standings.

Prediction and Best Bet

Expect a tight, low-margin game that comes down to whether Golden State’s defense can slow down Wilson enough in the paint to make Las Vegas one-dimensional. The Valkyries have the depth and the home crowd, but Wilson’s playoff scoring surge and the Aces’ perfect season-series record are hard to bet against in a one-game sample.

• Prediction: Las Vegas Aces 84, Golden State Valkyries 80
• Best Bet: Aces -1.5

This is the best bet because Las Vegas has already shown it can win in Chase Center this season, has the rest advantage, and brings a superstar in Wilson who is playing the best playoff basketball of her career — all factors that tip a near pick’em number in the Aces’ favor for Game 1.
