What It Is

A jackpot is a big winning -- often the largest a competition or event has to offer.

How It Works

Let's say John Doe goes to Las Vegas to get away from his wife for a few days. He puts a few dollars in a slot machine and pulls the handle. Three red cherries pop up, lights start flashing, and music starts playing. John has won a $250,000 jackpot -- the largest payout the slot machines offer. He collects his winnings and leaves his wife, who later sues him for half.

Why It Matters

In the finance world, a jackpot is similar to a windfall -- it is an amount of money that is usually unexpected and usually very large. Jackpots can be the result of investing in IPOs that do well, holding onto a stock that everybody else left for dead, or investing in assets that were undervalued.

Note, however, that when you win a jackpot, the IRS does too -- income is taxable, regardless of whether it was expected.
