After 14 seasons in the NBA, Cleveland Cavaliers legend Tristan Thompson has officially confirmed his retirement from professional basketball. The 35-year-old center made the announcement on the May 28 episode of Khloe Kardashian's Khloe in Wonder Land podcast, bringing an end to a career that saw him win an NBA championship and establish himself as one of the most tenacious rebounders of his era.
The Announcement: How Thompson Confirmed His Retirement
Thompson revealed on the podcast, hosted by his former partner and mother of two of his children, that his playing days are officially behind him. "Honestly, it's been great," Thompson said. "I always tell people it feels like I'm a rookie again." The Brampton, Ontario native went unsigned during the 2025-26 NBA season, making his last stint with the Cavaliers during the 2024-25 campaign. He appeared in 819 regular-season games, averaging 8.3 points, 7.8 rebounds and 1.0 assists per contest.
Timeline: From No. 4 Overall Pick to NBA Champion
Thompson's NBA journey began when the Cleveland Cavaliers selected him with the fourth overall pick in the 2011 NBA Draft out of the University of Texas. He quickly made an impact, earning NBA All-Rookie Second Team honors in 2012. The defining moment of his career came in 2016 when he was a key starter on the Cavaliers team that made history by rallying from a 3-1 deficit to defeat the Golden State Warriors in the NBA Finals. Thompson started all 21 playoff games during that championship run, averaging 6.7 points and 8.6 rebounds. Over the years he also played for the Boston Celtics (2020-21), Sacramento Kings (2021-22), Indiana Pacers (2022-23), Chicago Bulls (2023-24) and Los Angeles Lakers (2024), before returning to Cleveland for one final season in 2024-25.
Why Thompson's Retirement Matters: A Legacy of Toughness
Thompson carved out a reputation as one of the league's premier offensive rebounders and an energy big man who impacted winning without needing the ball in his hands. He recorded 56 career double-doubles and ranked among the league leaders in offensive rebounding for several seasons. His willingness to do the dirty work — setting screens, crashing the glass and defending bigger opponents — made him invaluable during Cleveland's championship runs. For his career, Thompson averaged 8.3 points and 7.8 rebounds while shooting 52.6% from the field. He notably averaged a career-best 12.0 points and 9.0 rebounds per game during the 2015-16 season, cementing his role as a core piece alongside LeBron James, Kyrie Irving and Kevin Love.
Where Things Stand Now: Life After Basketball
Thompson isn't taking a traditional path into retirement. Rather than moving into sports broadcasting — the typical route for many former players — he's setting his sights on artificial intelligence and technology. "What could I do that can be impactful and be outside the box?" Thompson asked. "I've always been a sponge. Now, for me, it's about pivoting into AI and tech. How can I be part of where the world is going and not where the world is currently at?" He also emphasized that he's not waiting around. "I'm not gonna wait five, four years to get back into doing something. I'm gonna go right now." Thompson also reflected on the challenges athletes face in retirement, noting, "A lot of guys waste time on sitting in their own s--t and trying to figure out, 'Why is it over? Can I still come back from this and play?' For me, it's like, no. The iron's hot, on to the next."
What Happens Next: Family and Future Ventures
Fatherhood remains a top priority for Thompson, who is father to Prince Thompson (9) with ex Jordan Craig, True Thompson (8) and Tatum Thompson (2) with Khloe Kardashian, and Theo (4) with Maralee Nichols. He has been clear that he's not adding more children to the mix, revealing on the podcast that he underwent a vasectomy after an ultimatum from Kardashian, saying, "I already have enough baby mommas, I don't want no more." As for his professional future, Thompson appears ready to embrace the same relentless approach he brought to the basketball court. Whether it's tech investments, AI ventures or other business opportunities, the former Cavaliers star is treating his post-NBA life with the same intensity he once reserved for chasing championships.
