He was born in Fort Lauderdale, Florida but grew up in Elloree, South Carolina. He left school at sixteen to ride horses professionally at Pimlico Race Course in Baltimore, Maryland. His first win was on a horse named Vaya Con Dinero. Soon, he left Maryland to race in New York and New Jersey and at the age of 18 was the United States Champion Jockey by wins with 469.
In the late 1980s Antley spent time in a substance abuse clinic. In 1987 he became the first rider to win 9 races on 9 different horses in a single day and in 1989, he won at least one race a day for 64-days straight.
In 1990, Antley moved to California and in 1991 he rode Strike the Gold to victory in the Kentucky Derby. In 1997 he temporarily retired to deal with weight and drug problems. Then in 1999, Antley returned to ride the D. Wayne Lukas trained Charismatic, and they won that year's Kentucky Derby and Preakness Stakes.
In the 1999 Belmont Stakes, Charismatic finished third in the race, but he had injured his leg in the stretch run. Antley jumped off the horse after the finish line and attempted to hold the horse's leg in place while the horse limped. Due in part to Antley's efforts, the horse was able to recover following surgery.
A stock market player, Chris Antley wrote an investor newsletter he called "The Antman Report." During the week leading up to the 1999 Belmont Stakes, he was invited to ring the Opening Bell at the New York Stock Exchange.
In December 2000, Antley was found dead on the floor of his Pasadena, California home. The cause of death was severe blunt force trauma and was investigated by police as a homicide. Later, the coroner's report concluded that Antley had died of multiple drug overdose and the injuries were likely related to a fall caused by the drugs.
Chris Antley is interred in the Bookhart Cemetery in Elloree, South Carolina, the town he considered his home. Shortly after his death, his wife, Natalie Jowett, a former ABC Sports employee, gave birth to their daughter, Violet Grace Antley.
