Lottery jackpots in the United States have seen a remarkable surge in size over the past decade.
When Powerball was introduced in 1992, its inaugural jackpot stood at $5.9 million, as reported by the Multi-State Lottery Association. Fast forward to November 7, 2022, when the record-breaking Powerball jackpot reached an astonishing $2.04 billion.
Mega Millions has also experienced a similar trajectory. The game’s first jackpot winner in 2002 walked away with $28 million, while its highest jackpot, a staggering $1.602 billion, was won on August 8, 2023, marking it as the sixth-largest jackpot in U.S. lottery history.
Notably, thirteen of the twenty largest jackpots in history have occurred since the beginning of 2023. The second-largest jackpot ever, an impressive $1.817 billion, was won in Arkansas on Christmas Eve in 2025.
Currently, five states remain without lottery ticket sales: Alabama, Alaska, Hawaii, Nevada, and Utah.
Despite the enormous prizes on offer, the odds of winning remain incredibly slim. Over the last thirty years, both Powerball and Mega Millions have undergone multiple redesigns aimed at increasing jackpot sizes while providing more opportunities for players to win smaller prizes.
In Powerball, players select five numbers from 1 to 69 and one Powerball number from 1 to 26. In 2015, the game expanded its pool of white balls from 59 to 69, while the red balls were reduced from 35 to 26.
Before this change, the odds of winning the jackpot stood at 1 in 175.2 million, with the overall odds of winning any prize at 1 in 31.85. Post-redesign, the odds of winning the jackpot became even more challenging at 1 in 292.2 million, although the overall odds of winning any prize improved to 1 in 24.9, according to the Multi-State Lottery Association.
Mega Millions requires players to choose five distinct numbers from 1 to 70 and one Mega Ball number from 1 to 24. To win the jackpot, players must match all six numbers drawn.
In 2025, Mega Millions revamped its game, introducing a larger starting jackpot of $50 million compared to the previous $20 million, which “enhanced the odds of winning the jackpot as well as the overall winning odds,” noted Dan Miller, a spokesperson for Mega Millions.
Miller explained that every winner now receives more due to a built-in multiplier for non-jackpot prizes, which can range from 2X to 10X. As of December 5, 2025, players had won $531 million in non-jackpot prizes under the new game format, a significant increase from the $119.8 million that would have been awarded under the old rules—a remarkable 343% rise in player winnings.
For instance, under the previous system, matching just the Mega Ball resulted in a break-even scenario where a $2 ticket yielded a $2 prize. Under the new structure, that same match now guarantees a minimum prize of $5, which can be multiplied, allowing players to win amounts of $10, $15, $20, $25, or even $50 instead of just $2.
The odds of winning the Mega Millions jackpot improved from 1 in 302.6 million to 1 in 290.5 million due to the removal of one gold Mega Ball from the game. This adjustment has made it easier to select the correct combination of numbers for the jackpot. Additionally, the overall odds of winning any prize shifted from 1 in 24 to 1 in 23.
Furthermore, the financial stakes have increased as well: Powerball raised its ticket price from $1 to $2 in 2012, while Mega Millions elevated its ticket prices from $1 to $2 in 2017 and from $2 to $5 in April of this year.
