Records continued to tumble as Book 2 of the Keeneland September Yearling Sale concluded Thursday, with the auction powering past $300 million faster than ever and the million-dollar market showing no signs of slowing down. But beneath the extraordinary strength at the top, there were also signs of increasing selectivity. From soaring averages and a growing seven-figure club to milestone moments for Norevale and Mt. Brilliant, here are eight things we learned from Book 2.1). Keeneland Hits $300 Million in Record TimeLast year, Keeneland September reached $300 million after four sessions faster than at any time in its history. This year, it did it even faster. The cumulative gross through Book 2 stands at $318,115,000, compared to $307,639,000 at the same stage last year.Another record didn't last long.2). What Three Years of Numbers Tell UsThe average has climbed from approximately $305,000 in 2024 to $360,031 in 2025 and $392,271 this year–a gain of almost 29% in two years.The median tells a slightly different story. It jumped from approximately $260,000 in 2024 to $300,000 in 2025, before holding steady at $300,000 this year.So while prices continue to rise overall, the latest gains are being driven more heavily by strength at the upper end of the market.3). It's Not All RosesBut that strength doesn't extend everywhere. The four-day buy-back rate has risen from 27.07% in 2025 to 30.06% this year, another indication that buyers are becoming more selective away from the top of the market.Cormac Breathnach summed it up: “There is a little selectivity in the market.”4). 19 of the Top 20: Colts Dominate at the TopThe numbers point to a clear preference for colts through Books 1 and 2. A total of 345 colts have sold for $194.6 million, averaging $564,072, compared to 288 fillies grossing $123.5 million at an average of $428,854.The median is $400,000 for colts versus $350,000 for fillies.But the difference is even more pronounced at the very top: 19 of the 20 highest-priced yearlings so far are colts. Of the sale's 65 seven-figure yearlings through Thursday, 49 are colts, and just 16 are fillies.At the top end of this year's September market, the boys are firmly in front.5). The Million-Dollar Club Keeps Growing Another 10 yearlings made $1 million or more Thursday, taking the Book 2 total to 24, up from 18 last year. Through four sessions, 65 yearlings have now made seven figures, already well ahead of last year's record-setting figure of 56.And 230 yearlings have made $500,000 or more, bought by 109 different entities.6). Taylor Made Tops the Tables Taylor Made Sales Agency led the Book 2 consignors, selling 58 yearlings for $21,110,028. The partnership of St. Elias, West Point Thoroughbreds, Lane's End Racing and Belladonna Racing led the buyers, taking home 10 yearlings for $8,650,000.7). Life Is Good for the Dooleys Six years after Leo and Sarah Dooley launched Norevale Farm, and only two years after they began consigning under their own banner, they have their first million-dollar yearling.CHC, Maverick Racing and Light Post Ventures paid $1 million for their Life Is Good colt, Hip 941.Another big step for one of the industry's emerging operations.8). An Emotional Day for Mt. Brilliant Mt. Brilliant had never sold three seven-figure yearlings in a single session. On Thursday, it did.But the milestone was an emotional one for brothers Bo and Hutton Goodman, whose father, Greg, is in ICU battling serious health issues and was absent from Keeneland.“We've never done that before,” Hutton said. “And it's kind of emotional because it's the first time in our lifetimes that our dad hadn't been here with us.”A remarkable day for the farm, with the man who would have enjoyed it most very much in their thoughts.The post Eight Things We Learned From Book 2 at Keeneland September appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
