The Keeneland November Breeding Stock Sale entered its Book 4 section with the auction's sixth session Sunday. For the session, 264 horses grossed $9,962,200 for an average of $37,736 and a median of $29,000. With 65 horses reported not sold, the buy-back rate for the session was 19.76%.“The market was good,” said Walker Hancock of Claiborne Farm, which sold all 14 horses it sent through the ring Sunday and also purchased the session topper. “It's the same song and dance, if you had a young mare that wasn't exposed, with an early cover, you were going to do very well. We know how the market perceives these older mares that have had a few foals and maybe haven't hit the mark. Late covers are tough, as well. But the young mares with attractive covering sires sold very well.”The average (-7.88%) and median (-3.33) for Sunday's sixth session were down from the corresponding session at the record-setting 2025 auction and the buy-back rate was up. A year ago, 267 horses sold for $10,937,500. The average was $40,964 and the median was $30,000. The session's buy-back rate was 17.85%.The sixth session in 2025 produced double-digit gains from the corresponding 2024 session, with the average up 14.7% and the median up 20.00%. The 2026 session average and median were both slightly ahead of the 2024 figures, when the session average was $35,713 and the median was $25,000.“It's hard to have a record sale on top of a record sale,” Hancock said. “To me, this is more in line with where the market should be. I think it's a very fair market. I think horses are bringing what they should, whereas last year, you could probably say horses were at a premium for whatever reason. Maybe it was the market dynamics at the time, but I think this is more of a fair market that we are working with this year.”Claiborne Farm made the highest purchase of Sunday's session, going to $240,000 to acquire the 7-year-old mare Hypersport (hip 2150), a daughter of the historic nursery's leading broodmare sire Blame. A two-time stakes winner, Hypersport sold in foal to Fierceness and was consigned by Taylor Made Sales Agency.“Obviously, we are very partial to Blame,” Hancock said. “I don't think you can have too many of them and we will continue to collect them when we see an opportunity. She's a Blame mare with some speed and black-type. That's what drew us to her.”Of the mare's price tag, Hancock said, “If she was in a different book, I don't know that she'd bring that much. But she was well spotted and, to me, she stood out today as a mare that had quality in this book. When you are spotted well, you usually get paid. It was probably a very fair price for her.”A colt by Yaupon was the highest-priced weanling at Sunday's session when selling for $180,000 to Clover Creek Racing.Bred by Deann and Greg Baer and consigned by Scott Mallory, the weanling is out of War Tap (Tapit), a full-sister to stakes winner Siem Riep and a half to stakes winner Please Advise (Palace Malice).Eighteen horses sold for six figures during Sunday's session. There were 20 who hit that mark a year ago.Cumulatively, Keeneland has sold 1,302 horses through the ring at the November sale for a gross of $227,705,900, for an average of $174,889 and a median of $90,000.
