The Mega Millions jackpot reached $1 billion on Friday, marking the second-largest prize in U.S. lottery history.
The $1 billion prize refers to the annuity option. Most winners opt for cash, which for Friday night's drawing would be $565 million. A Mega Millions prize of any amount can be claimed up to one year from the date of the drawing.
Although the jackpot keeps increasing, the odds of winning remain at one in 302.5 million. Tickets for Friday's drawing can be purchased until 10:45 p.m. ET, 15 minutes before the live televised drawing. Tickets cost $2 each.
