Scott took up the New Jersey-based role in December 2019, having previously served as the chief executive of Ladbrokes Australia.
Prior to this, he was trading director at Ladbrokes.com.au for five years and had a spell as racing bookmaker at Tatts Group, while he was also a racing analyst for Humbleton.
Scott confirmed his departure in a LinkedIn post published on 31 March.
“It is with a mix of sadness and happiness that after 11 years in the Entain/BetMGM family today is my last day and I’m heading back to Australia,” Scott said. “It’s been a fun ride, playing my small part in the growth of two business evolving into a couple of fairly substantial entities.
“There are far too many people to name, however I must single out Adam Greenblatt (BetMGM chief executive), who I first met in 2013 when on behalf of Ladbrokes UK he acquired a small Australian business called boookmaker.com.au, which evolved into the Ladbrokes and Neds juggernaut.
“I have spent the last three-and-a-half years working for Adam at BetMGM and there is no better leader in any category anywhere on the globe. Under Adam, with the guidance of the executive team, I’m excited to watch from afar the inevitable progress of BetMGM over the next 24 months.”
