WNBA Championship Analysis

It will be a battle of competing styles in the 2025 WNBA Finals this year. The Phoenix Mercury played well enough on the offensive end of the court, but thrived by playing lockdown defense and keeping scores low. They had the fifth-best defense during the regular season, allowing 80.1 points per game.

But in the playoffs, they have had the No. 1 defense in the league, holding teams to 75.5 points per game.

As for the Aces, Las Vegas has had a tumultuous journey this season. They struggled to find an identity early in the season, but once things started to click, their offense took over, and they couldn’t lose. At the end of the regular season, they ranked No. 6 in scoring (83.6 points per game).

In the playoffs, however, they put up 87 points a night (No. 1).

So, will the WNBA Finals be a case of defense winning a championship, or will offense win games (and, essentially, the championship)?

WNBA Championship - My Pick

I can understand why the Aces are favored and why they are a popular bet. They’ve played decent enough defense while outscoring everyone. However, they failed to close out Game Two vs. Seattle in the First Round. They needed overtime to win Game 5 vs. the Fever with Indiana down its two best players.

Phoenix is healthy and playing the best defense of the season. However, we should also factor in the regular season series, which Vegas won 3-1, with two games decided by three goals and a blowout victory in the final game (Aug. 21). A’ja Wilson averaged 25 points, 12 rebounds, and three assists.

The key for Phoenix is containing Wilson, and with how well they’ve played defense in the postseason, I believe they can. I’m taking the Mercury to pull off the upset and win the 2025 WNBA Championship (+105).

How to Bet on WNBA Championship Odds

There are essentially two ways to bet on the WNBA Championship: (1) futures odds that are available practically year-round and subject to change at any moment, and (2) the traditional betting line that will become available once the final two teams have been decided.

The act of placing a bet is pretty simple. All you’ll need to do is follow these steps: (1) register for an account with the sportsbook you want to place your bet, (2) deposit sufficient funds into your account, (3) locate the WNBA Championship odds at your sportsbook of choice, and (4) place your bet.

How to Read WNBA Championship Odds

Reading WNBA Championship odds is easier than Caitlin Clark hitting a three-pointer. Odds will consist of a three-digit number that will either be – or +. If a number has a – in front of it, then it will have a greater than 50% chance of winning. Consequently, if it has a +, then it has less than a 50% chance of winning.

If the odds have a – sign (i.e., -110, -250, -500, etc.), then the number will be how much you have to bet to win $100. For example, for a market with -500 odds, you’ll need to bet $500 to win $100. For those with + signs, the number is how much you’ll win if you bet $100.

So, let’s say you bet on a team to win the WNBA Championship, and that team has +1200 odds. A $100 bet will result in a $1300 payday, your stake ($100) plus $1200 in winnings.

Where to Bet on WNBA Championship Odds

The following are my preferred online sportsbooks for betting on the WNBA:

• BetMGM: BetMGM typically has game odds posted in a pretty timely fashion (which is not the case for every sportsbook). I’m a big fan of their same game parlay builder, too. You will not have the OVER/UNDER as an option, but there will be more players and markets to choose from than at several sportsbooks. New users of BetMGM are eligible to claim the welcome offer by using our promo code WSNSPORTS when creating a profile: Bet $10, Get $150 if You Win*.
  
  *Bonus Bets Expire in 7 Days. One New Customer Offer Only. Add’l terms.

• bet365: I’m a fan of any sportsbook that offers bonus bets for a welcome offer, but that’s not the only reason why I like bet365 sportsbook for WNBA betting. Like BetMGM, they often tend to have odds posted sooner than other books, which gives me more time to research and decide on what markets I want to bet on. Use our promo code WSN365 to join bet365, and claim the following bonus: Bet $5, Get $200 in Bonus Bets Win or Lose.

• FanDuel: Like bet365, I like that FanDuel Sportsbook offers bonus bets to new users when they sign up: Bet $5, Get $300 in Bonus Bets if Your Bet Wins. Their odds, like the other two, are competitive, and they tend to post at least the traditional betting line in a pretty timely manner (and not just the morning of or late the night before).
