BetMGM, the US-facing joint-venture between MGM Resorts International and GVC Holdings, and Betgenius of Genius Sports, have extended their partnership to launch a same-game-parlay product for US sports called Parlay Builder.

Powered by Betgenius’ BetBuilder service, Parlay Builder claims to be the most sophisticated, wide-ranging same game-parlay product in the US market, offering players unmatched bet selections across NFL, NBA and all major soccer leagues, with MLB and NHL to be added soon.

BetMGM players can now instantly build, customize and bet selections within the same game from a choice of over 400 bet-types, including team and player props.

BetBuilder is a service developed by Betgenius and sportsbook software provider Sportcast which automates the entire back-end process while allowing sportsbooks to configure each bet type and to fully customize the UX.

Matt Prevost, CMO at BetMGM, said: “Parlay Builder gives our pre-game betting offering another dimension; it’s engaging, easy-to-use and extensive, therefore appealing to serious and recreational bettors alike. We’ve witnessed the success of BetBuilder in Europe and anticipate a similar trajectory in the US.”

Matt Stephenson, Global Partnerships Director at Betgenius, added: “BetBuilder has been a runaway success for many of our partners in Europe and the product keeps getting better and better. With a focus on US sports and the deepest range of bet options, Parlay Builder gives BetMGM a real differentiator – both from a product and marketing perspective.”
