So Happy (foaled April 26, 2023) is a Grade I winning American Thoroughbred racehorse who won the 2026 Santa Anita Derby.

Background

So Happy is a bay colt who was bred in Kentucky by Leverett S. Miller and is out his of a lightly raced mare, So Cunning.[3] So Cunning's sire is Blame, the 2010 American Champion Older Male Horse.

So Cunning descends from the winning Staff Writer mare So Divine. So Divine was the first filly that Miller bought his wife, Linda after they married and many of the offspring the couple owned in partnership, or she owned herself, have carried the word "So" in their names. An average racehorse, So Divine went on to be a solid producer. Included in her progeny was 1996 Grade III Virginia Handicap at Calder Race Course winner Race Artist, multiple stakes winner So Dashing, stakes winner So Charming, and So Frank, who set track records at Bluegrass Downs in Paducah, Kentucky for both one and two miles.[4]

So Happy's sire is Runhappy, the 2015 US Sprint Champion who won the Grade I Breeders' Cup Sprint that year. Runhappy was sold in 2025 for stud duties in South Korea.[3]

So Happy had initially been sold for $12,000 as a weanling at the 2023 Keeneland November Breeding Stock Sale and $20,000 as a yearling at the 2024 Fasig-Tipton Kentucky Fall Yearling Sale. Trainer Michael Glatt bought the colt as an agent for $150,000 at the 2025 Ocala Breeders' Sales March Sale of 2-Year-Olds in Training for Hans and Ana Maron's Saints or Sinners and Robert Norman's Norman Stables.[3]
