WNBA Championship Trends: Why a Strong May Matters in 2026

WNBA opening night is Friday, with 15 teams seeking good starts. But how important is a strong May performance? Each of the past four eventual WNBA champions finished the opening month with winning records.

To get a sense of where each of the previous 29 champions stood after May, and as part of our WNBA season preview 2026 insight, RotoWire.com broke down the numbers. The season is 44 games, but a good first month can boost WNBA championship odds.

How Strong May Records Predict WNBA Champions

This century, the WNBA's regular season has expanded from 32 games (from 2000 to 2002) to 34 (from 2003-22), then 40 (from 2023-24) and now a 44-game docket over the past two seasons.

Though the league year has expanded (along with the number of teams to the current 15), it's important for would-be WNBA championship contenders to start on the right foot. Each of the past four title winners have posted a combined record of 22-5 (.815) in May, making this a WNBA betting trend worth watching.

This topic affects WNBA playoff odds and has become more relevant in recent seasons, which have been starting earlier. Eight times in league history, the season didn't even start until after May, and in several other years there were three or fewer games in the calendar's fifth month.

Las Vegas Aces May Success and Championship Blueprint

Over that span, each of the three Las Vegas Aces' championship teams have hit the ground running on The Strip. The 2022 squad posted the best May record (9-1) in WNBA history.

A'ja Wilson and company also started 4-0 in 2023 and 3-2 last season to get their championship campaigns underway with a solid WNBA win-loss record early.

Given the presence of Wilson and her four WNBA MVPs, along with veterans such as Chelsea Gray and Jackie Young, roster construction has played a key role in Vegas' steady ascent of late, making the Aces a consistent favorite at legal sports betting apps.

There's proof in the pudding about whatever head coach Becky Hammon has been doing in Sin City. That .815 winning percentage in May over the three championship seasons since 2022 in Las Vegas speaks for itself.

One Team That Bucked the Hot Start Trend

Only one eventual WNBA champion posted a sub-.500 record in May after playing more than one game that month. That was the Chicago Sky in 2021.

That year, coach James Wade's team marched through the playoffs despite a 16-16 regular-season record. The Sky rebounded from a 2-4 start in May to reach the playoffs, where they knocked off the Dallas Wings, Minnesota Lynx, Connecticut Sun and Phoenix Mercury in succession to win the league title.

Chicago got hot at the right time, but it's also easy to look back and see how they succeeded and paid out nicely at the time for backers at sports betting sites. Two-time MVP Candace Parker and four-time All-Star Kahleah Copper called the shots offensively and five-time All-Star Courtney Vandersloot, who led the league in assists, manned the point for the Sky that season.

All told, Chicago's five starters all averaged double-digit scoring during the team's surprise title run, Vandersloot dished out 8.6 assists per game and Parker pulled down 8.4 rebounds on average to pace the Sky's attack.

New York Liberty 2026 WNBA Championship Odds and May Schedule

This season, 2026 WNBA championship futures odds can give us a clue to which clubs could fit the pattern of May success stories.

The New York Liberty have the top title odds across five major U.S. online sportsbooks, with futures ranging from +220 (on bet365, Caesars, DraftKings and Fanatics) to +350 at BetMGM Sportsbook. New York leads the 15-team league on each odds board.

All told, New York's average betting odds are +246 (or 28.9%) when you divide the team's futures across those five operators. The next closest club is the Aces at +413, demonstrating oddsmakers' collective belief that Sabrina Ionescu (above) and company will hit the ground running this WNBA season.

This year, New York has nine games in May, starting with Friday's opener at home against the Connecticut Sun. FanDuel Sportsbook installed the Liberty as a 11.5-point favorite in the Tri-State showdown as of May 7.

After that, New York has three straight road games. Sunday, the Liberty travel to Washington to face the Mystics, then has two in a row in Oregon against the expansion Portland Fire (on May 12 and 14). A five-game homestand against the Golden State Valkyries (May 21), Dallas Wings (May 24), Fire (May 25) and Phoenix Mercury (May 27 and 29) closes the month. That gives New York sports betting customers plenty of chances to dive into the new season.

The Liberty avoids the other top four preseason WNBA odds title contenders (the Aces, Atlanta Dream, Indiana Fever and Minnesota Lynx) in May. So there's a non-zero chance that New York starts the year 9-0, potentially paving the way for Chris DeMarco's club to knock off the Aces as the top performer in May and likely one of the WNBA best bets.

One thing to remember: The 29 eventual WNBA champions won 80.2% (73-18) of their games during May in those seasons. The importance of starting fast, beginning with Friday's opening night of games, is evident.
