Sports betting is gaining popularity as it becomes legalized in more states, and last year, the amount of women participating grew at a much faster rate than that of men.

More than 4.6 million women joined sports betting apps in 2021, according to Global Wireless Solutions, and female user rates grew 115% compared to 2020.

FanDuel added around 1.7 million female users last year. DraftKings brought in an estimated 900,000 women.

While the number of men on sports betting apps was 250% more than women in 2021, men’s growth rate was only 63%.

Some of the biggest sportsbook apps in the U.S. reportedly now have more female users than male, including BetRivers and its associated New Jersey outlet SugarHouse (54% to 46%).
