A pony does not "become a horse." Contrary to popular belief, a pony is NOT a baby horse, but rather an entirely different species.
A baby pony grows up to be an adult pony, and a baby horse (a 'filly' if female, a 'foal' if male) grows up to be an adult horse ('stallion' if male and not gelded, a 'gelding' if male and gelded, and a 'mare' if female.) The non-gender specific term for a baby horse is a 'colt'.
I assume that your question was meant to be, "when does a baby horse become an adult?" and the answer to that is indefinite. Generally, horses begin 'breaking in' (being trained to wear tack and carry riders) at sometime over 2 years. The general point at which horses reach sexual maturity is around 2 and a half years, though this varies between different genders.

A pony is not just a horse that is small because it is young - a pony is a breed of horse that is small even when full grown.
