Thompson chose to leave the University of Texas at the end of his freshman year in favor of entering the NBA draft. In June 2011, the Cleveland Cavaliers selected Thompson in the fourth round, and he made his NBA debut in December of that year. At the end of his first season on the team, he was named to the 2012 NBA All-Rookie Second Team.
In 2015, Thompson was a starter on the team, helping the Cavaliers reach the 2015 NBA Finals, though they lost to the Golden State Warriors.
At the end of the 2014-2015 season, he became a restricted free agent but ultimately re-signed with the Cavaliers with a five-year, $82 million contract, after four months of negotiations. At the end of the 2015-2016 season Thompson and the Cavaliers won an NBA championship, the team's first championship win in 52 years.
Thompson became the first player in Cavaliers history to play in 400 consecutive regular-season games in December 2016. That season and the following one both ended with losses to the Warriors in the Finals.
