About 15 Crystal Roses

The operator has no international locations. Well, it’s a state monopoly, after all. Holland Casino was also one of the first operators to launch online when the market legalised in 2021, with Petra de Ruiter joining the company as CEO the following year.

Petra’s journey to the role started in a hotel management school where she learned the ropes of hospitality, followed by a job at Transavia Airlines, a subsidiary of renowned Dutch operator KLM. This led to 24 years in the aviation industry, in a host of different roles: sales, marketing, operations – all aspects of the business that would later become useful in the casino industry.

Kalshi has imposed strict protocols for customer sign-up, which includes proof of US residency, along with a US tax identification number. The operator also requires traders to complete a robust know-your-customer check before trading on its site.

Land-based gambling can attract international investment. Cirsa expanded its Marrakech presence last November. Private online betting has no equivalent licensing route.

Cirsa’s own IPO prospectus is blunt about it: “Online gaming only exists for betting, which is operated by a state agency,” it says of Morocco, adding that online casino games “are not allowed”.
