It was found that Family and state blockholder have positive and significant effect on firm value at all cut off (10%-50%), political connections in the family, state, and public blockholder have significant positive effect on firm value. The result of this paper indicates that the structure of companies' ownership has contribution to determine the political connections in the conglomerates. The concentration of ownership in the company and family as controlling highest conglomerate in Indonesia as well as their involvement in politics implies that Indonesia has fallen into oligarchy state, in which the rules are held by a group of wealthy political elites.
