Introduction. The article deals with the problems of ecosystems formation and development as new forms of organizational and economic relations in the Russian economy. Artificial intelligence and neural networks are studied as elements of the modern economic ecosystems construction. Theoretical analysis. The classification of ecosystem services and platforms is presented, the ways of their formation using artificial intelligence are investigated. Among the services provided by ecosystems, the following services grouped by fields of activity can be distinguished: in the field of information technology there are cloud technologies; in the field of life – social networks; in the field of finance – Internet banking. In the case of providing these services, artificial intelligence automatically saves almost all the information about the client using special filescookies. There are two ways of forming ecosystems with the participation of artificial intelligence: the creation of appropriate functionality based on a large financial institution and the formation of an intelligent platform based on a powerful Internet company or a mobile operator. From the point of view of the introduction of artificial intelligence elements and neural networks, the main ecosystems in the Russian economy are analyzed: Sber, VTB, Tinkoff, Yandex, Mail.ru Group and MTS. Results. Modern integration processes lead to the creation of metaverses based on ecosystems, in which neural networks and artificial intelligence play a crucial role. These trends require further study and scientific understanding, as well as the development of an appropriate state strategy for regulating ecosystems and programs for the introduction of artificial intelligence elements into economic development mechanisms.
