The origin of the phrase is uncertain, but it is believed to have originated in American English in the early 19th century. One theory suggests that it may have been a reference to horse racing, where participants would bring their own ponies (horses) and contribute money towards the prize pool. "Ponying up" would then mean contributing one's fair share of money.
Another theory suggests that the phrase may have its roots in poker or gambling, as "pony" or "pony up" was often used to refer to a small amount of money.
