Cloud Computing (foaled April 29, 2014) is an American Thoroughbred racehorse who won the 2017 Preakness Stakes in only his fourth start.

Cloud Computing was bred in Kentucky by Hill 'n' Dale Equine Holdings and Stretch Run Ventures.

[6] Cloud Computing was purchased as a yearling at the 2015 Keeneland Sales for $200,000[2] by Seth Klarman, the owner of Klaravich Stables, and William Lawrence.

[7] Both hedge fund managers, they chose his name based upon their pattern of using terms from the finance industry to name their horses,[8] other examples being graded stakes winners Takeover Target and Currency Swap.

[2] Cloud Computing did not make his racing debut until February 11, 2017, when, as a three-year-old, he won a maiden special weight at Aqueduct Racetrack.

In mid-stretch, Classic Empire had a three-length lead and looked the likely winner before Cloud Computing angled out from traffic and started closing ground rapidly.

[13] It was the first win of a Triple Crown race for his trainer Chad Brown and the second for jockey Javier Castellano, who was riding the colt for the first time.
