Predictions for the Belmont Stakes rely on factors such as exposure of the participating horses, trainers and jockeys. The genetic background of specific horses, the year of the race and the horses' performance on other tracks also matter when predicting the outcome of the Belmont Stakes.
Analyzing previous data on Triple Crown races provides the basis for Belmont Stake predictions. Analysts use decision trees with input variables such as track lengths, finish time, horse trainers and jockeys to come up with performance estimations. Evaluating the history of jockeys and trainers is also a helpful predictive measure. Jockeys and trainers with a history of success at the Belmont Stakes have a higher likelihood of winning than those without exposure to the track. Jockeys have to judge the pace correctly, have patience and be able to master the track within a short period.
Horse breeding also contributes to the outcome of horse races. Some winning horses for the Belmont Stakes trace their roots back to horses that participated in the race 10 generations back. Apart from the genes, a horse's breeding helps to determine its performance on turf or dirt surfaces. The performance
of horses at the Belmont Stakes also depends on their performance during the preceding Kentucky Derby. Horse racing fans also rely on betting odds to predict the outcome of the Belmont Stakes.
