(NEXSTAR) – Someone could start their Thanksgiving evening a few million dollars richer thanks to a huge Mega Millions jackpot up for grabs.

Without a winner on Friday, the Mega Millions jackpot has grown to an estimated $489 million, with a cash option of $229.3 million before the next drawing. If you want to try your luck, you may only have a few hours to buy a ticket before Tuesday’s drawing at 10:00 p.m. CT.

The Mega Millions’ current top prize has increased since September, when a ticket sold in Texas netted an $800 million jackpot, the seventh-largest payout in the game’s history.

At $489 million, Tuesday’s potential prize is about $63 million outside the top 10 largest Mega Millions jackpots. To be among the largest in the game’s history, Tuesday night’s jackpot needs to go unclaimed and is estimated to reach $553 million. Then it would surpass a $552 million jackpot won in Illinois in June.

1. $1.602 billion: August 8, 2023; Florida
2. $1.537 billion: October 23, 2018; South Carolina
3. $1.348 billion: January 13, 2023; Maine
4. $1.337 billion: July 29, 2022; Illinois
5. $1.128 billion: March 26, 2024; New Jersey
6. $1.050 billion: January 22, 2021; Michigan
7. $800 million: September 10, 2024; Texas
8. $656 million: March 30, 2012; Illinois, Kansas and Maryland
9. $648 million: December 17, 2013; California and Georgia
10. $552 million: June 4, 2024; Illinois

However, the jackpot payout will be less than the announced $489 million. Due to federal, state and local taxes, the total annuity price would be $256 million to $309 million, according to USA Mega. The cash prize would be between $134.2 and $144.5 million.

If you’re lucky enough to win the jackpot, even if you’re not the only winner, experts recommend quickly putting together a team that includes a lawyer, an accountant and a financial advisor. They also recommend protecting your ticket and keeping your win a secret for as long as possible.

This may be easier in some states than others – only a select few allow winners of such a large jackpot to remain anonymous.

Mega Millions tickets cost $2 each and are sold in 45 states, the District of Columbia and the U.S. Virgin Islands. In addition to Tuesdays, drawings also take place on Fridays at 10:00 p.m. CT. Players have a 1 in 24 chance of winning a Mega Millions prize.

The national lottery game is set to undergo profound changes in spring 2025.
