Many draft outlooks ranked Carter-Williams as a top point guard prospect and a top ten prospect overall. Carter-Williams was selected 11th overall in the 2013 NBA draft by the Philadelphia 76ers. Carter-Williams, along with Nerlens Noel, were both officially signed by the 76ers on September 24, 2013. On October 30, 2013, in his NBA debut, he recorded 22 points, 12 assists, 7 rebounds, and 9 steals (the most steals ever made by a rookie on debut) in a 114-110 win over the defending champion Miami Heat. Less than a week later, he had a 26-point, 10 assist performance in a 107-104 win over the Chicago Bulls. He was subsequently named the Player of the Week in only his first week in the NBA, a feat last achieved by Shaquille O'Neal in 1992. On November 9, 2013, Carter-Williams recorded a career-high 13 assists to go with 21 points in a 127–125 double overtime loss to Cleveland.
