Putin’s primary objective is to cause enormous chaos in all aspects of American life, according to Foundations in Geopolitics, the Russian playbook:

Russia should use its special services within the borders of the United States and Canada to fuel instability and separatism against neoliberal globalist Western hegemony, such as, for instance, provoke “Afro-American racists” to create severe backlash against the rotten political state of affairs in the current present-day system of the United States and Canada. Russia should “introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social, and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics”.

Any “stuff” he gets - land, territory, money, etc.- is all gravy. All he really wants is for America to devolve into such disorder and chaos, that their influence in the world dissolves.
