2026 Blue Book release sets global stakes race standards for sales catalogs
The 2026 Blue Book decided how stakes races were labeled in sales catalogs, shaping black type, comparability and what buyers were willing to pay.
The Blue Book rarely gets the spotlight, but it sets the terms for how a stakes race is valued once a horse leaves the track and enters the sales ring. The 2026 International Cataloguing Standards Book, released on April 20, listed the stakes races from each country that will carry Group, Graded or Listed status in sales catalogs, giving breeders, buyers, consignors and auction houses one common language for quality.
That matters because black type is not just decoration on a page. In a catalog, the difference between Group, Graded and Listed status can change how a pedigree reads, how a mare is marketed and how a yearling is priced. The book is published by The Jockey Club Information Systems in association with the International Federation of Horseracing Authorities, and its standards are approved by the Society of International Thoroughbred Auctioneers. For the people setting reserves, writing catalog pages and making bids, it is one of the sport’s quietest but most powerful reference points.
The structure behind it is global. The International Grading and Race Planning Committee coordinates the book, drawing input from racing authorities around the world. That coordination is the whole point. Grading standards can differ by jurisdiction, even when the racing sits inside the same Thoroughbred market, so the Blue Book helps keep a horse’s record legible from one sales company to the next and from one country to another.
The first edition was published in 1983, and that history explains why the book still carries weight four decades later. It is part of racing’s long effort to standardize information that would otherwise be fractured by borders, regulators and catalog formats. The result is practical, not ceremonial: a race’s label in the Blue Book can shape how it is represented in pedigrees, how it appears in sale materials and how confidently a buyer can compare one horse against another.
In that sense, the 2026 edition is more than a directory of stakes status. It is part of the price discovery machinery of the bloodstock market, the hidden infrastructure that helps the international Thoroughbred business speak the same language when a horse is ready to sell.
