Curlin surges to No. 5 in sire rankings after Derby weekend boost

One graded-stakes weekend at Churchill Downs was enough to shake the sire market, and Curlin made the sharpest move of all. Powered by Golden Tempo’s Kentucky Derby breakthrough and Corporate Power’s Alysheba Stakes win, Curlin jumped from No. 14 to No. 5 in BloodHorse’s updated sire rankings, a rise that carries real commercial weight because those tables are built on progeny earnings.

The signal is bigger than one hot stretch. Curlin is 22 and will not be active for the rest of the 2026 breeding season because of a recently discovered low fertility issue, which makes every major runner he gets on the track even more valuable. Golden Tempo, a 3-year-old Curlin colt, delivered the kind of result that can reset a stallion’s narrative in one race, while Corporate Power added a graded-stakes older-horse win in the Alysheba, worth $750,000 added, to keep the momentum rolling.

Golden Tempo’s Derby score on May 2 was the headline act. He won the 152nd Kentucky Derby by a neck over Renegade, and Cherie DeVaux became the first woman to train a Kentucky Derby winner. The race drew 150,415 fans to Churchill Downs, and the financial impact for Curlin’s resume was immediate: Equibase said Golden Tempo earned $3.1 million for the victory and pushed his career bankroll to $3,433,000 after just five starts. He was also undefeated in two starts in 2026 after his Lecomte Stakes win earlier in the year.

Corporate Power gave Curlin a second major boost on May 1 by surviving an inquiry to take the Alysheba over Skippylongstocking. That kind of graded-stakes win from an established runner matters in sire rankings because it adds breadth, not just flash. Together, Golden Tempo and Corporate Power showed why Derby weekend can rapidly reorder the commercial conversation around a stallion.

The broader leaderboard still belongs to the usual heavyweights. Not This Time held firm at No. 1 by getting three stakes winners across the weekend in Rhetorical in the Turf Classic, On Time Girl in the Eight Belles, and Imaginationthelady in the Edgewood. Gun Runner moved up as well after his daughter Always a Runner won the Kentucky Oaks, while Nyquist slipped the other way in the shuffle.

The deeper context says Curlin’s surge is not a fluke. BloodHorse’s sire-list archive shows he has finished outside the top seven only four times in 14 crops of runners, with those exceptions coming in 2012 through 2014 and again in 2024. Even so, the latest Equineline top-sires table still had Curlin at No. 10 on $7,246,266 in progeny earnings, behind Not This Time at No. 3 on $14,576,191 and Gun Runner at No. 7 on $8,300,329. That is the market in miniature: one Derby weekend can lift a stallion fast, but only the proven names keep finding their way back to the top.
