The Mega Millions and Powerball jackpots are over $300 million each.
Business Insider previously asked billionaire Mark Cuban for his advice for lottery winners who get rich overnight.
He said before anything else, hire a tax attorney. Then, choose the annuity payout over the lump sum.
As of Thursday afternoon, the Mega Millions jackpot was at $306 million. The Powerball jackpot reached $384 million.
This weekend, someone could win that money and become rich in a matter of moments.
