There’s no official rule that says what you can call a class—so a show manager can call any class a grand prix if they want to. However, there are some regulations for certain types of grands prix. From the USEF rule book:
Standards: Any class offering $25,000 or more in prize money must be offered at one of the following standards delineated below: Regional, American, National, or High Performance. Heights alone do not apply to these classes and the standard must be clearly stated in the prize list. Competitions must apply to the Jumper Committee for permission to offer $25,000 or more in prize money in any class if it does not meet one of the following:
