Powerball’s massive jackpot will rollover and increase after Saturday’s drawing produced no winning tickets, according to the game’s website.
The $1.4-billion jackpot now grows to $1.55 billion but remains the third-largest in Powerball’s history (the second largest was $1.586 billion in 2016).
The last time someone won the Powerball jackpot after the July 19 drawing for the $1.08 billion pot. The winning ticket then was sold in California.

On top of that, even if the expected return is good, you have to take into account the Kelly Criterion https://en.wikipedia.org/wiki/Kelly_criterion which limits how much of your bankroll you want to spend on a longshot, and if that’s less than the cost of a single ticket, buying tickets is more likely to bankrupt you than for you to win.
