Jockeys who win the Kentucky Derby typically earn about 10% of the first-place prize money. For the 2025 Kentucky Derby, the total purse for the winner is $3.1 million, so the winning jockey stands to make approximately $310,000 from the prize money

. In addition to this prize money share, jockeys also receive a guaranteed riding fee for participating, which is at least $500 for the Derby

. The 10% jockey share is a common arrangement, with the horse owner receiving about 80% and the trainer about 10% of the winner's prize

. For example, in 2024, winning jockey Brian Hernandez Jr. earned $310,000 for his victory on Mystic Dan, which was 10% of the $3.1 million first-place prize

. This pattern is expected to continue for the 2025 Derby as well. In summary:

• 2025 Kentucky Derby winner's purse: $3.1 million
• Typical jockey share: 10% (~$310,000)
• Guaranteed riding fee: at least $500
