parlay

If you parlay a bet, then you take the winnings from one bet and bet it again on something else. You might have seen a gambler on TV parlay her winnings into a huge fortune.

The verb parlay is often used to talk about gambling, but it can be used more broadly to describe any initial stake that you turn into something much larger.
