Do Jehovah’s Witnesses believe that God equips humans today with the gift of prophecy? On a number of occasions, God revealed information about future events that were to take place by giving humans the gift of prophecy. Do Jehovah’s Witnesses believe God still does this today, or has that means of communication ceased to be used?
No Jehovah’s Witnesses do not believe that the gift of prophecy is given in our day.

We believe that the gifts given to early Christians served a special purpose in establishing that Gods favor had shifted away from the nation of Israel and was upon the followers of Jesus Christ the Messiah. 

However those gifts like healing ,speaking in tongues, prophesying etc came to an end not long after the death of the apostles.  Insight on the Scriptures says


  Gifts of the Spirit. In the first century C.E. miraculous gifts attended the baptism with holy spirit. These served as signs that God was no longer using the Jewish congregation in his service but that his approval rested on the Christian congregation established by his Son. (Heb 2:2-4) On the day of Pentecost, miraculous gifts accompanied the outpouring of the holy spirit, and in each case mentioned thereafter in the Scriptures where the miraculous gifts of the spirit were transmitted, at least one of the 12 apostles or Paul, who was directly chosen by Jesus, was present. (Ac 2:1, 4, 14; 8:9-20; 10:44-46; 19:6) Evidently, with the death of the apostles, the transmittal of the gifts of the spirit ended, and the miraculous gifts of the spirit ceased altogether as those who had received these gifts passed off the earthly scene.
