The 17-year-old forward arrived at the club last summer in a reported £3 million double deal with Jeff Reine-Adelaide, who has made the step up the the Gunners first team
Arsenal did not make any signings on transfer deadline day, but they have handed a professional contract to one of their most promising youngsters.
Yassin Fortune, who joined the club alongside Jeff Reine-Adelaide from Lens in the summer of 2015, signed his first senior contract on Tuesday.
The 17-year-old has featured once for the club's Under-21 side and has been a regular fixture in the Under-18 team this season, scoring seven goals in 15 games.
Fortune will now be hoping to follow in the footsteps of Reine-Adelaide, who made his Arsenal debut off the bench in an FA Cup victory over Sunderland on January 9.
