G1 status at the time
Flat racing only. Group 1 and Grade 1 are treated together. Historic equivalents and domestic-only classifications are kept separate where identified. A modern G1 label does not automatically apply to earlier editions.
Prize money, with context
Career earnings include all race classes. They are not G1-only earnings or a trainer’s personal income. The worldwide horse list converts source totals at a common exchange-rate date. Original amounts and the calculation remain available in record details. Values are not inflation-adjusted.
Evidence before completeness
This research edition contains sourced historical records. It is not yet a complete global Top 50 for every category. Regional coverage is stated in the ranking choices; each entry opens its record details.
