(CNN) - One horse has earned the backing of Amazon in Saturday’s Kentucky Derby.
"Audible" the horse shares his name with "Audible" the audio-books application, which Amazon bought in 2008.
The horse is not named after "Audible" the company.
Still, Amazon is promoting the coincidence ahead of the race.
Audible the company announced on Twitter that if audible the horse wins, they will give away free "American Pharaoh" audiobooks to everyone in the U.S.

In 2015, "American Pharoah" became the first horse since 1978 to take the coveted triple crown by winning, the Preakness and Belmont Stakes and the Kentucky Derby.
Amazon's Audible is also donating to the "Thoroughbred Aftercare Alliance," a nonprofit that works with groups that help care for retired racehorses.
