The 2021 Breeders' Cup World Championships is the 38th edition of the premier event of the North American thoroughbred horse racing year.

The Breeders' Cup is generally regarded as the end of the North America racing season, although a few Grade I events take place in later November and December.

A record 56 horses were based outside the United States — 26 from Great Britain, 17 from Ireland, 8 from Japan, 2 from France and 1 from each of Argentina, Peru and South Africa.

Spectators were allowed with appropriate health measures, unlike the 2020 event that was held with only essential personnel in attendance, due to the COVID-19 pandemic in the United States.

[10] Corniche was also an easy winner in the Juvenile and will contend with Jack Christopher, who was scratched from the race due to a minor injury, for the title of champion two-year-old colt.

Meanwhile, Modern Games, his stablemate in stall 1, was released from the front of the gate to avoid possible injury and was quickly pulled up.

Single race bets (win, place, show and exotics involving either Albahr (#2) or Modern Games (#1)) were refunded.

[12] In the Juvenile Fillies Turf, Pizza Bianca won after a last-to-first stretch run that was captured on an on-board camera mounted on the helmet of her jockey, José Ortiz.
