Atomic Blonde bloodline gains value after Napoleon Solo's Preakness win

Napoleon Solo’s 1 1/4-length Preakness victory over Iron Honor did more than give Chad Summers another major trophy. It pushed Atomic Blonde into the center of a bloodline story that now carries real breeding-market weight, with Glennwood Farm producing a second Preakness winner in less than a decade and another headline name for a family that has already shown it can turn depth into value.

Atomic Blonde matters because she is not just the dam of a classic winner. She is by Scat Daddy, the same sire as 2018 Triple Crown winner Justify, and both mares were bred by the Gunther family and raised at Glennwood Farm near Versailles, Kentucky. That shared backdrop matters in commercial terms because it points to repeatable class, not a lucky break. Glennwood’s recent graduates also include Grade I winners Leslie’s Rose and Grand Mo The First, along with past standouts Vino Rosso, Tamarkuz, First Samurai, Stevie Wonderboy, Stay Thirsty and Mo Town.

The mare’s own race record helps explain why the family has staying power. Atomic Blonde won the $150,000 South Beach Stakes at Gulfstream Park on Jan. 25, 2020, after finishing third in the 2019 Winter Memories Stakes at Aqueduct in her stakes debut. Bloodstock buyers and breeders can see the difference between a mare who produced one good horse and a mare whose own résumé says she had usable speed, class and durability. TDN noted that Atomic Blonde is the sole stakes winner out of Volver to date, but that is exactly the kind of female line that can gain value quickly once a better horse appears beneath it.

Napoleon Solo’s rise only sharpens that case. Summers bought the colt for $40,000 at the 2024 Keeneland September sale after Glennwood consigned him, a modest price for a horse that has now won the Preakness at Laurel Park, the first Preakness ever staged there while Pimlico Race Course is rebuilt. Summers said the colt came out of the race in fantastic shape, and the result gives fresh context to the family’s sales profile. What once looked like a sensible yearling purchase now reads like a market inefficiency.

Atomic Blonde’s breeding plan adds to the appeal. She was covered by Stage Raider for 2026, but the pregnancy slipped, and she is now in foal to Flightline on a March cover for 2027. With Stage Raider, a half-brother to Justify, beginning stud duty in 2025 at Crestwood Farm and Flightline already established at Lane’s End, the mating choices show Glennwood is building for the next cycle, not just cashing in on the last one.
