When Shai Gilgeous-Alexander earned his MVP title in late May 2025, fans couldn’t seem to stop lauding the Thunder star. But a question still lingers. Is it one, two, or perhaps more hidden figures fueling his drive?
Today, Gilgeous-Alexander stands as the embodiment of both individual brilliance and communal support. He has one biological brother, Thomasi, who remains his closest confidante off the court, and a cousin, Nickeil, whose relationship transcends mere family ties to become that of a brother-in-arms.
In the unforgiving arena of the NBA, Gilgeous-Alexander’s story is a testament to the power of sibling bonds, regardless of whether they share a last name or a stat sheet.
Beneath the bright lights of Paycom Center, whispers swirl about a secret sibling network shaping every crossover and clutch jumper. As Gilgeous-Alexander emerges as one of the NBA’s premier talents, the answer is both simple and surprising—a tale of blood, bond, and basketball destiny that stretches from Ontario to the American heartland.
The Brothers Carving Their NBA Future Just Like Shai Gilgeous-Alexander
At face value, Gilgeous-Alexander has one biological brother: Thomasi Gilgeous-Alexander. Born two years apart, Shai (July 12, 1998) and Thomasi (November 10, 2000) grew up in Toronto under the guidance of parents Vaughn Alexander and Charmaine Gilgeous—both former athletes.
Charmaine, an Olympian sprinter for Antigua and Barbuda (1992), and Vaughn, a high school basketball standout in Toronto, instilled athleticism and discipline from the start.
Thomasi followed his older brother into basketball, playing collegiately for Northeastern Oklahoma A&M before transferring to the University of Evansville Purple Aces. While Gilgeous-Alexander’s path led to the NBA, Thomasi carved a niche in college hoops as a sharpshooting guard at Evansville. Before Evansville, he spent his 2018-19 season under The Potter’s House in Jacksonville.
Yet another name often surfaces in discussions of “Shai’s brothers”: cousin Nickeil Alexander-Walker. Though not a blood brother, Nickeil, born the same year as Gilgeous-Alexander, played alongside the Thunder star at Hamilton Heights Christian Academy, where they shared a dormitory at coach Zach Ferrell’s home.
This shared past followed them to the 2025 NBA playoffs when Gilgeous-Alexander and Alexander-Walker locked horns in Game 4 on May 26. Although Gilgeous-Alexander claimed the win for his OKC brothers and added 40 points, Nickeli left his mark on the court in equal measures by guarding his cousin and bringing the heat to him.
However, the bond was still tight beyond the hardwood as Gilgeous-Alexander’s words about Nickeil, “He’s literally like my second brother,” echoed the postgame media session room and across social media.
“He’s literally like my second brother. He’s been through every stage of life with me… But I am trying to take his head off for sure.”

Not to digress, Nickeil’s NBA journey—drafted 17th overall in 2019 by the Brooklyn Nets, and was immediately shipped off to the New Orleans Pelicans. Now, he is a key rotation piece for the Minnesota Timberwolves, making them inseparable on and off the hardwood.
Through childhood tournaments and summer leagues in Hamilton, Ontario, the duo tightened a bond more akin to twins than cousins.
Behind every jump shot, Gilgeous-Alexander’s family narrative threads through each chapter of his life. Parents Charmaine and Vaughn divorced when the Thunder star was a toddler, yet both remained avid supporters. Vaughn’s coaching in local Toronto gyms paired Shai with Nickeil, who arrived at their home when his mother juggled two jobs.
This childhood morphed into a story for the NBA history books. In the words of Gilgeous-Alexander himself, the NBA MVP said that their dreams as brothers came into fruition at last. “He got the better of me sometimes, I got the better of him. Stuff we’ve dreamt about for our whole lives, and it’s crazy that it’s come to fruition.”
All’s fair in family and basketball 😂

What unites Shai, Thomasi, and Nickeil is more than genetics. It’s a shared quest for excellence. When Shai clinched the 2025 Western Conference MVP, his father and aunt Nicole (Nickeil’s mother) were courtside, cheering every step of the way. Now, the Thunder is headed for the NBA Finals against the Pacers.
Meanwhile, by the 2024–25 season, Gilgeous-Alexander had firmly established himself as one of the league’s premier talents. He led the NBA in scoring with 32.7 points per game, guiding the Thunder to 68 wins (a franchise record) and earning both the Western Conference Finals MVP.
Over his six-year career through 2024–25, Gilgeous-Alexander has averaged 24.1 points, 4.8 rebounds, and 5.1 assists per game, shooting 50.1% from the field, 35.5% from three, and 86.2% from the free-throw line.
For Thomasi, living in his brother’s shadow was both a challenge and an inspiration. Their father’s relentless training sessions and brotherly one-on-one matchups honed Thomasi’s craft. Soon, Gilgeous-Alexander’s own brother would get his chance and the right to create his NBA legacy as he is still developing his skills.
In every thunderous dunk and decisive pull-up, the echoes of the brothers’ shared past resonate—proof that brotherhood in the Gilgeous-Alexander clan transcends DNA. As the three brothers continue their NBA journeys, the basketball world watches a family legacy unfolding—one where two names appear on NBA rosters, but three hearts beat as one.
