This is a completely irrelevant achievement. Nobody can reasonably expect this to be repeatable, and if enough people make predictions somebody will get it right. It's so blatantly irrelevant, I assume this company only cares about selling and not at all about their technology being able to do anything better than chance.
Not strictly repeatable, but easily testable if they got lucky or not. There are thousands of horse races a year. Heck there are 2 more races left in the triple crown this year. It would be interesting to see if they could do the same for Preakness and Belmont. At some point they will either revert to the mean or show they have some serious predictive power in their methods.
