Kentucky Stallion Books and Fees, 2026

Preliminary The Jockey Club Report of Mares Bred · reports received through October 1, 2026 · released October 13

Covers, advertised fees and list-price value for 171 stallions at seventeen Kentucky farms, with 2025 comparisons. The analysis is in Inside Kentucky’s Stallion Portfolios.

List-price value is reported covers multiplied by each stallion’s advertised breeding-season fee. It measures published pricing against reported breeding activity. Discounts, late-season premiums, conditional-fee programs and seasons that pay the farm nothing sit outside it, and what each farm collects is private. Covers are The Jockey Club’s preliminary counts, which it revises in later reports.

Method and Sources

How the figures are built

The panel covers 171 stallions at seventeen Kentucky farms, 16,592 of the state’s 16,677 reported covers. Covers come from The Jockey Club’s preliminary reports through September 30, 2025, preserved in an archived BloodHorse table, and October 1, 2026, with stallions matched by name. List-price value is covers multiplied by advertised fee, with private fees excluded; it does not capture discounts, premiums, conditional-fee programs or seasons that pay the farm nothing. Using Practical Joke’s revised $100,000 fee for 2025, Ashford’s returning-roster decline is 24.2% to 24.7% across Golden Pal’s two documented fees (20.1% at Practical Joke’s initial $75,000). Farm means 2026 standing location; ownership may be shared.

Figure 10 is restricted to stallions standing in Kentucky in both 2025 and 2026, 155 matched, and excludes new entrants, departures and horses that changed states. Figure 9 uses BloodHorse’s 2025 Quality of Mares Bred, covering-season data through October 2, 2025. Every figure’s data table sits under it; the analysis and its full set of tables are in Inside Kentucky’s Stallion Portfolios.
