Many publications focus on the deficit nature of the Olympic Games organisation, when considered from the point of view of host cities – organisers of such events. However, does such an event actually affect the region and the host country in a positive way? The presented article aims at the assessment of the organisation of mass sports events, such as the Olympic Games, taking into consideration entrepreneurial activities which can be defined in terms of a productive, destructive or socially destructive category. In order to determine the relevant types of entrepreneurship, the authors refer to well-established definitions (in the case of productive and socially destructive types) and to their own, original definition of destructive entrepreneurship.
