Medaglia d'Oro Dies at 27: The Sire of Rachel Alexandra, Songbird and Golden Sixty

Medaglia d'Oro, one of the most important American stallions of the last 20 years, died on Friday, Oct. 16, 2026, at Darley's Jonabell Farm in Lexington, Kentucky. He was 27, had been pensioned at the end of the 2025 breeding season, and will be buried at the farm.

Darley called him a perennial leading sire. His name sits in the pedigrees of champions on three continents, and his daughters are still racing at the top level this fall.

Medaglia d'Oro dies at 27: what was announced

Medaglia d'Oro, the Thoroughbred stallion who won the Travers, Whitney and Donn and then sired 31 Grade 1 winners, died on Oct. 16, 2026, at age 27. Darley America announced his death that day, and BloodHorse reported the same details.

Here is what has been officially stated:

• Where: Jonabell Farm, Darley's Kentucky base in Lexington
• Age: 27
• Status: Pensioned (fully retired from breeding) after the 2025 season
• Resting place: He will be buried at Jonabell

No cause of death was given, and we won't guess at one. Twenty-seven is a good long life for a horse; if you own an older horse, our care guide covers the basics.

Dan Pride, chief operating officer of Godolphin America, said his legacy will not be forgotten.

His racing career: Travers, Whitney and Donn

Medaglia d'Oro was bred in Kentucky by Albert and Joyce Bell. He raced for owner Edmund Gann and was trained by Hall of Fame trainer Bobby Frankel.

He was tough and consistent rather than flashy. He won 8 of 17 starts, earned more than $5.7 million, and posted 14 triple-digit Beyer Speed Figures, a rating of how fast a horse ran.

He also won four Grade 2 races: the 2002 San Felipe and Jim Dandy, and the 2003 Strub and Oaklawn Handicap.

Just as telling were his near-misses. He was second in the 2002 Belmont Stakes, the 2003 Pacific Classic, the 2004 Dubai World Cup and two straight Breeders' Cup Classics. Few horses keep showing up in races that big for three seasons.

What a sire, leading sire and graded stakes winner mean

If you're new to racing, the breeding talk can sound like code. Here's the plain-English version.

Sire and dam

• Sire: the father of a horse. Dam: the mother.
• Damsire (broodmare sire): the mother's father. A stallion's daughters keep spreading his influence long after he stops breeding.
• Foal crop: all the foals a stallion sires in one year. His first crop is the first test of whether he passes on his talent.

Leading sire

A leading sire is a stallion whose offspring earn the most money or win the most important races in a given year or region. Sire lists rank stallions by their runners' total earnings, so one stallion can top the list nationally, or for a single category such as 2-year-olds or turf.

Calling Medaglia d'Oro a perennial leading sire means he ranked near the top year after year, not just once.

Graded stakes winner

Stakes races are the top tier of racing. In North America the best ones are graded: Grade 1 is the highest level, then Grade 2 and Grade 3. Europe, Australia and Asia use the word Group instead.

A graded stakes winner has won at least one of those races. Siring more than 100 of them, and 31 Grade 1 winners, puts a stallion in rare company. Our explainer on what a Grade 1 race is goes deeper.

Shuttle stallion

A shuttle stallion breeds mares in the Northern Hemisphere spring, then flies south to breed again during the Southern Hemisphere season. That can nearly double the number of mares he covers in a year.

Medaglia d'Oro began shuttling to Darley's Kelvinside farm in Aberdeen, New South Wales, in 2010, according to Australian outlet The Straight, and covered eight Southern Hemisphere books there.

Medaglia d'Oro offspring: the stars he sired

His first crop alone delivered Rachel Alexandra, who won the 2009 Kentucky Oaks and was 2009 Horse of the Year. That made him the obvious answer to anyone searching "Rachel Alexandra sire."

His best-known runners include:

• Rachel Alexandra: Kentucky Oaks winner and 2009 Horse of the Year
• Songbird: Eclipse Award champion filly
• Nitrogen: Eclipse champion still racing in 2026
• Golden Sixty: Australian-bred, three-time Hong Kong Horse of the Year
• Plum Pretty and Good Cheer: Kentucky Oaks winners, giving him a record three Oaks winners
• Tam Tam: 2026 winner of the Del Mar Oaks and Queen Elizabeth II Challenge Cup

In 2017 he had seven individual Grade 1 winners. Darley says only Mr. Prospector, Danzig and Storm Cat have matched that among American stallions in a single year. His stud fee peaked at $250,000 a mating; see how stud fees work for what that buys.

In Australia he sired Vancouver, winner of the 2015 Golden Slipper, and Astern, winner of the 2016 Golden Rose. Both went on to sire Group 1 winners themselves.

Why one stallion can shape a breed

A good mare can have roughly one foal a year. A popular stallion can sire well over a hundred foals a year, and a shuttle stallion even more. That math is why one horse's traits can spread through a whole breed in a decade.

His influence keeps moving in three ways:

1. Through his sons at stud: Vancouver and Astern carried his line forward in Australia.
2. Through his daughters as broodmares: The Straight reports his daughters have produced 161 individual stakes winners, including 13 Group or Grade 1 winners.
3. Through the racing record: breeders keep booking mares to stallions whose runners win the biggest races, so success compounds.

The flip side is a smaller gene pool if everyone breeds to the same few horses. Breed registries and breeders track that closely. Medaglia d'Oro's case shows the upside: soundness, consistency and stamina passed on across generations.

What to watch next: his daughters at Keeneland

His story isn't over yet. Darley says he had five graded stakes winners in 2026 alone.

• Nitrogen: The champion mare, trained by Mark Casse, won the Ogden Phipps and the Beldame this year. Her team has pointed her to the Breeders' Cup Distaff on Saturday, Oct. 31, at Keeneland.
• Tam Tam: She led all the way to win the Queen Elizabeth II Challenge Cup at Keeneland on Oct. 10. Her Breeders' Cup plans had not been confirmed in the reports we checked.
• Future crops: He bred through 2025, so his last foals will reach the races in the coming years.
