To be more precise, it was a coversation between two business men representing each separate company and is meant "I will carry your share of money." (in which "your share" means "your portion" but not a sock share).
In this case, is it clear that he who is carried has to pay back the money or it depends ?
Actually, it sounds to me like the other man doesn't have enough money (to invest or whatever) right now, so the speaker is saying that he will lend him the portion he needs, and it can be paid back later.
But that is still not necessarily the meaning from the context you have supplied.
