Few stallions in Quarter Horse racing are having a year like Lainie Whitmire’s Flying Cowboy 123, and the two-time AQHA Racing Champion has added another defining achievement to a rapidly growing sire résumé.
Standing at Lazy E Ranch near Guthrie, Oklahoma, Flying Cowboy 123 currently sits atop both the AQHA Leading Sires by Money Earned and AQHA Leading Two-Year-Old Sires by Money Earned lists. His remarkable season was punctuated Monday when undefeated Cowboys Flying captured the $3 million All American Futurity (G1), giving Flying Cowboy 123 his second winner of Quarter Horse racing's most prestigious futurity from only four crops to reach the races.
As of September 9, Flying Cowboy 123 leads all sires with $9,564,588 in 2026 progeny earnings from 392 starters and 157 winners, including 22 stakes winners.
His dominance among juvenile sires has been equally impressive. Flying Cowboy 123's 206 two-year-old starters have produced 82 winners and seven stakes winners while earning $6,212,698, placing him No. 1 among the nation's leading sires of two-year-old money earners.
Leading that powerful juvenile crop is Cowboys Flying, whose perfect six-for-six season has produced earnings of $1,822,793.
The 2024 gelding from the Carters Cartel mare Cartels Lady has emerged as the nation's premier juvenile with victories in the All American Futurity (G1), TQHA Sale Futurity (RG1), and Texas Breeders Futurity.
His All American victory gave Flying Cowboy 123 an extraordinary second winner of the race in just four crops to race.
Flying Cowboy 123's first All American Futurity winner, Cowboys Gun Z, captured the 2024 edition before being named AQHA Racing Champion Two-Year-Old and Champion Two-Year-Old Gelding. The son of the Tres Seis mare CF Smokin Gun has earned $1,678,945 and later added the Refrigerator Championship Stakes (G1) to his résumé.
The depth of Flying Cowboy 123's sire record extends well beyond his two All American winners.
His lifetime performers are headed by Cowboys Flying, Cowboys Gun Z and Lethal Cowboy 123, giving the stallion three individual runners with earnings exceeding $1.5 million.
Lethal Cowboy 123, out of Pretty Lethal by First Down Dash, earned $1,547,872 while becoming an AQHA Racing Champion Two-Year-Old, Champion Two-Year-Old Gelding and AQHA Supreme Race Horse. His major victories include the Los Alamitos Two Million Futurity (G1), Golden State Million Futurity (G1) and Vessels Maturity (G1).
Other leading runners by Flying Cowboy 123 include Ask Her To Fly SI 102, runner-up in the All American Futurity (G1) with earnings of $700,175; Flying Joy 1 SI 102, the $525,212 AQHA Racing Champion Two-Year-Old Filly and 2026 All American Oaks (G1) winner; Cardiac Cowboy SI 102, a 14-time winner of $491,689; and Electrifying Cowboy SI 104, a multiple graded stakes winner of $419,203.
Overall, Flying Cowboy 123 has sired 59 stakes winners and 63 stakes-placed runners, with his progeny earning more than $26.6 million. His 570 lifetime starters have produced 336 winners.
Those numbers have already propelled the relatively young stallion to 22nd on the all-time leading Quarter Horse sires list by money earned, an impressive position for a stallion whose oldest runners are still early in their racing careers.
His success on the racetrack is also being reflected in the sale ring.
Through September 8, 68 Flying Cowboy 123 yearlings sold in 2026 for $7,402,500, an average of $108,860, and a median of $72,500.
Flying Cowboy 123's rapid rise as a sire follows an exceptional racing career of his own.
A son of all-time leading living sire Apollitical Jess, Flying Cowboy 123 was named AQHA Racing Champion Two-Year-Old Colt in 2018 and AQHA Racing Champion Three-Year-Old Colt in 2019. He won eight of 13 career starts and earned $965,811.
At 2, he won the Texas Classic Futurity (G1) and finished third in the Rainbow Futurity (G1). The following season, he captured the Texas Classic Derby (G1), finished third in the All American Derby (G1), and was a finalist in the Ruidoso Derby (G1).
His pedigree provided an equally strong foundation for success at stud.
Flying Cowboy 123 is out of Hot Cash 123, by Takin On the Cash, a Dam of Distinction whose produce also includes Cold Cash 123, the $1,409,781 World Champion, AQHA Racing Champion Three-Year-Old and Champion Three-Year-Old Gelding.
Cold Cash 123 won eight stakes during his championship career, including the Rainbow Derby (G1), Texas Classic Derby (G1), Championship at Sunland Park (G1), Remington Park Invitational Championship (G1) and Southwest Juvenile Championship (G1).
Flying Cowboy 123's sire, Apollitical Jess, is one of the most influential stallions in modern Quarter Horse racing. The World Champion has sired the earners of more than $87.6 million, including champions KJ Desparado, Empressum, Apocalyptical Jess and Apollitical Blood.
But Flying Cowboy 123 is quickly establishing a sire legacy distinctly his own.
With more than $9.5 million in progeny earnings this season, the nation's leading juvenile sire title, 22 stakes winners in 2026, and now a second All American Futurity winner from only four crops to race, Flying Cowboy 123's 2026 season has further established the Lazy E Ranch stallion among the industry's elite sires.
And with Cowboys Flying still undefeated after six starts, his biggest year yet may not be finished.
