5 Jaw-Dropping Facts About Matthew McConaughey's Brother, Rooster: The Texas Oil Tycoon Who Made His Own Millions

The McConaughey family name is synonymous with Hollywood stardom, but the most intriguing and financially successful member of the clan might not be the one you think.

His story is one of raw Texas grit, entrepreneurial savvy, and a colorful personality that rivals his Oscar-winning sibling. The deep-rooted Texas swagger and financial independence of the McConaughey brothers—Rooster, Matthew, and their adopted brother Pat—is a testament to their unconventional upbringing. While Matthew built his fortune on the big screen, Rooster established his empire in the oil fields, creating a multi-million-dollar legacy that has earned him fame in his own right, particularly through his role as a no-nonsense investor on reality television.

The Texas Oil Tycoon: Building a Multi-Million Dollar Empire

Rooster McConaughey’s path to wealth is a classic American success story rooted in the unpredictable world of the Texas oil and gas industry. Unlike his brother Matthew, who pursued the arts, Rooster followed in the footsteps of their father, James Donald McConaughey, learning the oil business from a young age.

The foundation of his multi-million-dollar fortune is his company, DGM Supply. Rooster is the sole owner of this highly specialized oil pipe machine shop, which focuses on the buying and selling of used oil pipes. His deep knowledge of the industry, combined with a shrewd business sense, allowed him to capitalize on the cyclical nature of the oil market, securing massive profits over decades. He famously made—and subsequently lost—his first million dollars by the age of 30, a testament to the high-stakes risk inherent in his chosen field.

The "West Texas Investors Club" and Reality TV Fame

Rooster's distinctive personality and self-made success eventually led him into the spotlight, separate from his movie star brother. From 2015 to 2016, he starred in the A&E reality television series, West Texas Investors Club, alongside his long-time business partner, Wayne "Butch" Gilliam.

The show, which ran for two seasons, was often compared to Shark Tank, but with a distinctly rugged, Texas-style twist. Rooster and Butch would meet with aspiring entrepreneurs, often in unconventional settings, and evaluate their business proposals based on street smarts, common sense, and the potential for a solid return, rather than polished presentations. The show highlighted Rooster's authentic, no-nonsense approach to investing and his belief in doing business "the old-fashioned way." His continued public appearances, such as a special guest spot at the Odessa Rotary Club in January 2024, confirm his ongoing presence in the Texas business and social scene.

The Unconventional McConaughey Family Dynamics

The McConaughey brothers share a famously close, albeit unconventional, family bond, often speaking openly about their colorful, rough-and-tumble upbringing under their parents, Jim and Kay McConaughey. The family narrative is a core component of the McConaughey brand.

The Unique Names of Rooster's Children

Perhaps the most famous detail about Rooster, which perfectly encapsulates his Texas swagger and sense of humor, is the names he chose for his children. Rooster and his wife, Suzanne McConaughey, named their son Miller Lyte McConaughey and their daughter Margarita McConaughey. The name Miller Lyte was an homage to the popular beer brand, which even resulted in Rooster being awarded a year's supply of free beer. This level of playful, unapologetic Texan identity is a trait shared across the entire McConaughey family.

The Relationship with Matthew and Pat

Despite their vastly different careers—one a Hollywood A-lister and the other a Texas oil mogul—Matthew and Rooster maintain a strong, supportive relationship. Matthew has often spoken about the profound influence his older brother has had on him. They have collaborated in the past, including appearing together on a podcast in 2020, where they discussed family life and their shared history.

The third brother, Pat McConaughey, is the adopted sibling and is notably the most private member of the family. Unlike Matthew and Rooster, Pat has intentionally remained out of the public limelight, choosing a quieter life away from the entertainment and business media.
