Record Keeneland September Yearling Sale Reflects Global Confidence in U.S. Thoroughbred Industry. LEXINGTON, KY (Sept. 21, 2024) – Keeneland’s September Yearling Sale concluded its record-breaking run on Saturday with total sales through the ring of $411,749,500 to be the highest-grossing Thoroughbred auction in the world. The average of $150,548 is a September Sale record, while the median of $70,000 equals the record for a September Sale. Fueling the dynamic results was competitive trade among the world’s most prominent buyers, driving the sale of 36 seven-figure horses (including one sold privately) for the most since 2005 and the purchase of a son of Curlin for $5 million – the highest price for a colt at the auction since 2006 and the most expensive horse sold at public auction this year in North America.
