The book provides a complete analysis of European bloodstock sales in 2025 for all foals, yearlings and older horses in Britain, Ireland, France, Germany and Italy. It also includes foals and yearlings either foaled in Europe or by European-based sires at the major auctions in North America and Japan.

Furthermore, the Bloodstock Sales Review features comprehensive overviews of the trading year for Tattersalls, Goffs, Tattersalls Ireland and Arqana, as well as tables of the leading sires of 2025 by yearling average, lists of the year’s most expensive yearlings and foals, and a roll of top historical auction prices.

To mark the publication of the book, we compiled a top ten of the most profitable British and Irish-based yearling sires last year.

We have worked out each sires’ profitability index by dividing their 2025 yearling average by their covering fee of 2023, when the offspring in question were conceived.

In sixth place...

Nathaniel

2025 yearling ave: 78,202gns/€99,356

2023 covering fee: £15,000

Profitability index: 5.47

Few middle-market sires can boast the sort of roll of honour that Newsells Park Stud stalwart Nathaniel does: the great Enable, further Classic winners Channel, Desert Crown and You Got To Me, other Group/Grade 1 scorers God Given, Lady Bowthorpe, Mutamakina, Poptronic and Quickthorn, and numerous other stars besides.

The son of Galileo still has market respect too, as illustrated by the fact that 34 of his 2025 yearlings conceived at a fee of £15,000 sold for an average of 78,202gns (€99,356), for a very healthy profitability index of 5.47.
