The basketball world has long been captivated by the telepathic chemistry between Stephen Curry and Klay Thompson, the duo famously known as the Splash Brothers.
Their ability to mirror each other’s movements and synchronize high-volume three-point shooting led many casual observers to wonder if they shared a biological connection.
Over their 13-year tenure with the Golden State Warriors, they redefined the perimeter game and established a dynasty built on elite marksmanship.
While they share an undeniable bond on the hardwood, their “brotherhood” is defined by professional excellence rather than a shared family tree.
The Biological Reality: Are They Actually Related?
To address the primary search intent directly: Klay Thompson and Stephen Curry are not biologically related. They do not share a common ancestry, nor are they cousins or distant kin.
Their “Splash Brothers” moniker is a professional nickname that reflects their on-court synergy and their shared ability to “splash” the net from long range.
Despite the lack of a blood relation, the two grew as close as family during their time in San Francisco, often describing their relationship as a brotherhood forged through competition and shared championship DNA.
The confusion often stems from the fact that both players were raised in remarkably similar environments. Both are the sons of former NBA players, which gave them a shared understanding of the professional lifestyle from an early age.
This common background likely contributed to their immediate rapport when Thompson was drafted by the Warriors in 2011, two years after Curry joined the franchise.
A Parallel Pedigree: Comparing the Curry and Thompson Lineages
While they aren’t brothers by blood, their family histories are mirror images of one another, rooted in professional sports excellence. Both families have produced multiple high-level athletes, creating a “sports royalty” atmosphere around both Stephen and Klay.
The Curry Basketball Dynasty
The Curry family is arguably the most famous shooting family in the history of the sport. Dell Curry, the patriarch, was a legendary sharpshooter who enjoyed a productive 16-year career in the NBA.
Stephen’s mother, Sonya Curry, was a standout volleyball player in college, ensuring that athleticism came from both sides of the family.
| Family Member | Role/Achievement |
|---|---|
| Dell Curry | Father; NBA 6th Man of the Year (1994); All-time leading scorer for Hornets. |
| Sonya Curry | Mother; Division I college volleyball player at Virginia Tech. |
| Seth Curry | Younger Brother; NBA veteran and one of the league’s all-time leaders in 3P%. |
| Sydel Curry | Younger Sister; Former collegiate volleyball player. |
The Thompson Athletic Legacy
The Thompson family boasts an equally impressive resume, led by Mychal Thompson, who was the first overall pick in the 1978 NBA Draft. Like the Currys, the Thompson children were raised in a house where professional sports were the standard.
Klay’s mother, Julie Thompson, was also a collegiate volleyball player, paralleling Sonya Curry’s background.
- Mychal Thompson: Father; Two-time NBA champion with the Los Angeles Lakers.
- Mychel Thompson: Older Brother; Played in the NBA for the Cleveland Cavaliers.
- Trayce Thompson: Younger Brother; A professional Major League Baseball (MLB) player.
The Origin of the “Splash Brothers” Nickname
The term that sparked a decade of curiosity was not a family designation but a digital creation. In December 2012, Warriors.com writer Brian Witt coined the phrase in a tweet after Curry and Thompson combined for seven three-pointers in a single half against the Charlotte Bobcats.
The nickname is a clever regional tribute to the “Bash Brothers,” the famous home-run-hitting duo of Mark McGwire and Jose Canseco who played for the Oakland Athletics in the 1980s.
The Warriors organization quickly embraced the hashtag, realizing it perfectly captured the aesthetic beauty of the duo’s jump shots.
From that point forward, “Splash Brothers” became a global brand, synonymous with the three-point revolution that would soon take over the entire league.
Statistical Dominance: How the “Brothers” Changed the Game
The impact of Stephen Curry and Klay Thompson on the NBA cannot be overstated. Before their arrival, the league was dominated by interior play and mid-range specialists. Together, they proved that a team could win at the highest level by prioritizing the three-point shot.
Breaking the Record Books
Throughout their partnership, they set nearly every meaningful record for a pair of teammates. They are the only duo in NBA history to record multiple seasons where both players made at least 250 three-pointers.
In the 2015-16 season, they combined for a staggering 678 three-pointers, shattering the previous league record for a duo by 153 makes.
Some of their most notable shared records include:
- Most career three-pointers made by a duo in NBA history (6,228).
- Most career playoff three-pointers by a pair of teammates (1,119).
- Only teammates to both score 50 points in a single game within the same season on multiple occasions.
Championship Synergy
The biological “non-relation” was irrelevant on the court, where they functioned as a single unit. They appeared in six NBA Finals together, winning four championships in 2015, 2017, 2018, and 2022.
Their success was predicated on their unselfishness; while Curry often drew the double-teams, Thompson was always ready to provide the secondary “splash” that demoralized opponents.
The “Third” Splash Brother: Myths and Realities
As the Warriors’ dynasty grew, the media and fans frequently looked for a “third brother” to join the elite shooting circle. Several players were unofficially given the title based on their shooting performances during specific seasons.
- DeMarcus Cousins: During his brief stint with the team, he jokingly referred to himself as the third brother, despite his career three-point average being significantly lower than the guards’.
- Jordan Poole: During the 2022 championship run, Poole’s explosive shooting led many to label him the “Third Splash Brother” or “Baby Steph”.
- Kevin Durant: While he was arguably the most talented player on the team during his tenure, he was rarely called a “Splash Brother,” as his game was seen as distinct from the backcourt’s specific shooting archetype.
The 2024 Departure and a Literal New Beginning
The historic 13-year partnership officially concluded on July 6, 2024, when Klay Thompson departed the Golden State Warriors for the Dallas Mavericks in a complex sign-and-trade deal. This marked the end of the most successful backcourt era in modern basketball history.
However, in a fascinating development for the 2025–26 season, the “Splash Brothers” nickname took on a literal meaning. The Warriors signed Stephen’s actual biological brother, Seth Curry.
While Seth does not have the same championship pedigree as Klay, he is one of the most accurate three-point shooters in league history, ensuring the tradition of elite perimeter play continues in San Francisco under a more technically accurate version of the name.
