According to an embodiment of the present invention, there is provided a method of preparing a rubber composition, which includes (a) synthesizing a living polymer by solution polymerization of a monomer mixture including a conjugated diene-based monomer in the presence of a first catalyst; (b) reacting some ends of the living polymer with a coupling agent; (c) reacting the remaining ends of the living polymer with an organotin halide compound to prepare an end-modified conjugated diene-based polymer solution; and (d) adding a second catalyst and a conjugated diene-based monomer to the end-modified conjugated diene-based polymer solution to induce solution polymerization.
