E-business sector in Poland is dynamically growing since its inception in the mid-90s of the 20th century. The number of new e-shops, portals or online applications, as well as turnovers is increasing every year. As a consequence, in 2013, e-commerce sector generated over 5% of Polish GDP. However, since such growth will not last endlessly, a research problem aroused . The purpose of this paper is to estimate a the number of companies enough to saturate this sector, as well as to forecast the maximum time needed to gain this status. A logistic regression model was used to measure the amount of enterprises within a moment of e-business market saturation, and duration needed to reach its peak. Conducted research are indicating that potential entrepreneurs should not delay the launch of their e-business. For existing businesses the consequences of the sector saturation should lead to an increase in professional management of e-business and/or an increase in the scale of such activity.
