The NMRHA Stallion Service Auction & Reining Derby

Our NMRHA Reining Derby for 3-6 Year Old Morgans is held each year at the Morgan Grand National & World Championship Show in Oklahoma City in October, and the prize money for this popular event is funded by our Stallion Service Auction.

These services are graciously donated by the stallion owners, and offer breeders a great opportunity to secure a formidable sire for their future Derby entry.

The World Champion Snaffle Bit/Hackamore class placings are used to determine placings in the Derby. We also award a sire jackpot to the highest placing sire that donated a service to our program.

DEADLINE FOR DERBY ENTRIES: SEPTEMBER 1st, 2026
