Keeneland opens one of the most important events on the Thoroughbred sales calendar on Monday, September 14, when the 2026 September Yearling Sale begins in Lexington, Kentucky.
Keeneland says 4,642 racing prospects are cataloged for the 83rd edition of the auction. The sale runs for 12 sessions through Saturday, September 26 and begins Monday at 1:00 p.m. Eastern.
A major marketplace for future racehorses
The September sale is closely watched because many of the horses offered are still at the beginning of their racing careers. Buyers are evaluating pedigree, physical development and long term racing potential before those yearlings ever reach the starting gate.
The auction also arrives during an important stretch for Keeneland. The track will host its fall race meet in October and then the Breeders’ Cup World Championships on October 30 and 31. OTB Bet readers can follow that championship path through the Breeders’ Cup guide.
Following a record 2025 sale
Keeneland enters the 2026 auction after a record setting 2025 September sale. The track reported more than $531.7 million in sales for 3,078 horses last year. The auction also produced 56 horses that sold for at least $1 million, while the average price reached $172,755 and the median reached $80,000.
Those figures do not guarantee the same outcome this year, but they provide useful context for the scale of the marketplace. Keeneland attracts buyers and sellers from across North America and abroad, so the sale often offers an early look at bloodstock trends that can influence future racing seasons.
New surroundings at Keeneland
The 2026 auction is also the first September sale with Keeneland’s new Paddock Building in use. The facility is part of a larger period of development at the track ahead of the fall meet and the Breeders’ Cup.
For racing fans, the sale is less about immediate race results and more about the next generation. Some of the horses going through the ring this month will eventually appear in maiden races, major juvenile stakes and the classic season.
Book 1 closes with record strength
Keeneland completed Book 1 on September 15 with another major jump at the top of the market. The second session produced $79.63 million in through the ring sales from 111 yearlings. A colt by Into Mischief sold for $3.7 million to M.V. Magnier and Peter Brant’s White Birch Farm, making him the most expensive horse of the sale through two sessions.
Twenty three yearlings sold for at least $1 million during the second session, a single session September Sale record. Across the first two days, 41 yearlings reached seven figures, the highest total for the opening two days in sale history. Book 2 concluded September 17 with another powerful session. Across the first four sessions, 633 yearlings sold through the ring for $318,115,000, up 3.41 percent from the corresponding period in 2025. The average reached $502,551 and the median was $360,000. Ten yearlings sold for at least $1 million on Thursday, lifting the sale total to a record 65 seven figure yearlings, already above the previous full sale record of 56 established in 2025. Three colts shared the Thursday session lead at $2 million, two by Not This Time and one by Nyquist. Book 2 itself produced $166,715,000 from 425 yearlings, with an average of $392,271 and a median of $300,000. The sale pauses September 18 and resumes with Book 3 on September 19.
OTB Bet will continue to focus follow up coverage on meaningful market records, major session toppers and racing connections rather than routine daily sale summaries.

Opening session results
The opening session produced $71,770,000 in gross sales. A Gun Runner colt led the session at $2.8 million, and 18 yearlings sold for at least $1 million, the largest opening day total of million dollar yearlings since 2005.
The result gives the sale an immediate market benchmark as Book 1 continues on September 15. OTB Bet will continue to track verified session results when they materially change the picture of the sale.
