Abstract: A variation in the performance value of a polymer being manufactured can be reduced. A prediction device (10A) that, in manufacturing of a polymer, predicts a performance value indicating performance of the polymer in a polymerization tank after a raw material is fed, and may include: an acquisition unit (111) that acquires, as a prediction observation value, an observation value observed, in current manufacturing of the polymer, as a value related to the manufacturing of the polymer; and a prediction unit (112) that predicts the performance value of the polymer being currently manufactured at a predetermined timing, from the prediction observation value acquired by the acquisition unit, by using a relation between an observation value acquired in past manufacturing of the same type of polymer as the polymer, and a performance value of the polymer at the predetermined timing in the past manufacturing.
