Sima You became the heir to his uncle, Sima Shi, who eventually died without any sons. It is known that Sima You was a person of mild-mannered character, who was expected to become King of Jin, but ended up being passed over due to his young age. The heir that was eventually chosen was Sima Zhao's first son, Sima Yan (Emperor Wu), who usurped the Cao Wei throne and established the Jin dynasty with himself as the new emperor in February 266.

Despite this, Emperor Wu continued to bestow titles upon Sima You, including the post of ''sikong'' on 16 September 276, replacing Jia Chong (who was made Grand Commandant). In order to strengthen his son's position, he ordered Sima You away from
