Provided are a polymer composite capable of imparting good processability to a rubber composition and, further, achieving balanced improvements in initial grip performance, grip performance stability, and abrasion resistance; and a method for producing the polymer composite. Also provided are a rubber composition and a pneumatic tire that are formed from the polymer composite. The present invention relates to a polymer composite obtained by mixing a resinous organic compound having a weight average molecular weight of 250 or more and a polymer having a weight average molecular weight of 3, 000 or more, the polymer being synthesized by polymerizing a conjugated diene monomer that is a conjugated diene-containing monomer.
