Pakistan currently has 140 to 150 nuclear warheads and the stockpile is expected to increase to 220 to 250 by 2025 if the current trend continues, according to a latest report by authors keeping a track of the country's nukes.

The current estimate of 140 to 150 nuclear weapons exceeds the projection made by the US Defence Intelligence Agency in 1999 that Pakistan would have 60 to 80 warheads by 2020.
