Musatov was born to a military family on 14 February 1976 in Rakvere, Estonia, then occupied by the Soviet Union. His father was Mikhail Ivanovich Musatov, a Russian politician who served continuously as a deputy of the State Duma from 1995 to 2011 and also belonged to the LDPR. Musatov grew up in Belarus, moving with his family to Moscow in 1985. He studied engineering as a cadet at the Moscow Higher Combined Arms Command School, graduating in 1997 with academic honors. He then received a master's of economics from the Finance Academy under the Government of the Russian Federation in 1999, and a law degree in 2003.
In 2003 he was elected as a deputy to the 4th convocation of the Russian State Duma. As a member, he served on the Security Committee.
