Keeneland has cataloged 4,635 horses for the 83rd edition of its September Yearling Sale, which will cover 12 sessions from Monday, Sept. 14 through Saturday, Sept. 26, the auction company said via a Tuesday press release. The 2026 catalogue features horses by 189 sires, including 24 first-crop sires represented by 1,072 yearlings. Last year's September Sale was the world's highest-grossing Thoroughbred auction in history with more than $531.7 million in sales for 3,078 horses. The number of million-dollar horses (56) along with the average price ($172,755) and the median price ($80,000) all set records for the sale. We are grateful to the breeders and consignors who continue to entrust Keeneland with their best horses.
