Colorado’s sports betting industry saw marked growth in June, despite the lack of most major league sports.

Fans in the Centennial State wagered more than $38.1 million between digital and retail sportsbooks, an increase of 49% over May, the first month betting became legal, according to the Division of Gaming. The state collected about $217,023 in sports betting taxes in June.

Ping pong was the top grossing sports for the second month in a row, raking in more than $9.1 million in wagers, followed by soccer ($4.1 million), golf ($3.4 million), MMA fighting ($2.2 million) and tennis ($1.3 million).

Analysts like Max Bichsel, vice president of U.S. business for Gambling.com Group, say fan enthusiasm is promising given the lack of mainstream sports.

“While table tennis was the most bet on sport for the second consecutive month in Colorado, expect baseball and basketball to begin to surge with the return of MLB and NBA, assuming games can continue into the summer,” Bichel said.

In-person sports betting may also gain momentum as casinos and their respective sportsbooks join the scene. In mid-June, casinos were permitted to reopen following an extended closure induced by the coronavirus pandemic.
