Coach John Calipari and the Wildcats had the No. 1 recruiting class entering the week, and Vanderbilt solidifies that spot.
"It was the best fit for me to develop on and off the court," Vanderbilt said. "Coach Cal has a proven system built for athletes like myself."
Vanderbilt announced his decision on ESPNU's social media platforms.
Vanderbilt (Victory Prep Academy, Houston) is the No. 4 power forward in the Class of 2017. He averaged 13.5 points, 10.9 rebounds and 3.7 assists on the Nike EYBL circuit with the Houston Hoops AAU program but was hampered by a foot injury in the fall.
He is the fourth five-star commitment in Kentucky's 2017 class, joining Nick Richards (No. 12), P.J. Washington (No. 16) and Quade Green (No. 21). Four-star guard Shai Gilgeous-Alexander (No. 43) rounds out the class.
