DES MOINES, Iowa (AP) — The largest lottery jackpot in the world is up for grabs in the latest Powerball drawing.

The prize has climbed to an estimated $1.5 billion, easily surpassing all other lotteries. The jackpot estimate is reviewed daily, so it could increase before Wednesday night’s drawing if ticket sales continue to exceed expectations.

The jackpot for the twice-weekly game started at $40 million on Nov. 4. No one has matched all six Powerball numbers since then, so the prize kept growing.

Lottery officials expect at least 80 percent of the 292.2 million number combinations will be purchased before the drawing.
