Powerball jackpot leaps to estimated $800 million for Saturday night drawing

The already massive Powerball jackpot keeps on growing.

No winning tickets were sold for the estimated $700 million pot of gold up for grabs in Wednesday night's drawing, which was already the game's biggest this year. So Saturday night, the grand prize will be at least approximately $800 million, Powerball officials say. The number could grow as more and more tickets are gobbled up.

Powerball jackpot winners have the option to get their prize in an immediate lump sum, which would amount to an estimated $383.7 million in cash value if someone wins Saturday, or as an annuity. That option pays out the full jackpot amount over roughly 30 years. All of that would be before taxes.
