After several weeks of no winners, the Mega Millions jackpot has increased to an estimated $1.35 billion — the second-largest jackpot in the game's history, according to Mega Millions officials.

But it's not just you who could benefit from buying a ticket. Lotteries also benefit some states.

Though specific systems differ between each state, each of the 45 states (along with the District of Columbia, Puerto Rico and the U.S. Virgin Islands) that offer lotteries donates a certain percentage of the revenue generated from ticket sales to specific state causes.

(Five states — Alabama, Utah, Alaska, Hawaii and Nevada — don't sell lottery tickets.)

Research shows that approximately 60% of the revenue from state lotteries goes directly to winners, as the states keep the remaining cash after paying out the prize money and paying certain costs such as advertisements.

For larger lotteries, like Mega Millions or Powerball, half of the ticket revenue goes toward the lottery's prize pool. The remaining half goes toward costs including lottery administration and retailer commissions, in addition to other beneficiaries, a Mega Millions spokesperson told ABC News.
