Following the early success of digital wagering in New Jersey, more states are pushing for the availability of online and mobile betting.
Bichsel, however, believes land-based casinos in the US are "not going anywhere."
Asked if the emergence of online sports wagering will lead to any cannibalisation, Bichsel told Gambling Insider: "There may be some cannibalisation but, ultimately, retail drives revenue and has a significant impact on the bottom line, as well as other parts of the business.
"These land-based casinos are not going anywhere. All over the world, there are mobile solutions existing alongside retail.
"So, until that revenue goes to zero, I don’t expect retail sports betting to go anywhere in the US; I think it will continue to be a pillar as states get comfortable with sports betting in general."
