I think Bookmakers typically get licensed to operate by applying to a reputable regulatory authority or gambling commission, which is responsible for issuing licenses to gambling operators in their jurisdiction. To obtain a license, bookmakers must go through a rigorous process where they are required to provide detailed information about their business model, financial stability, ownership structure, and management team. They must also demonstrate that they have the necessary systems and procedures in place to provide a safe and fair gambling environment for their customers.
