On Jan 31, 2010, the date of the cross-sell expansion, Mega Millions and MUSL each added lotteries; eight Powerball members added Mega Millions by May. The Montana Lottery joined Mega Millions on March 1. Nebraska added Mega Millions on March 20; Oregon followed on March 28; Arizona joined Mega Millions on April 18; Maine added Mega Millions on May 9; Colorado and South Dakota joined Mega Millions on May 16. The U.S. Virgin Islands joined Mega Millions in Oct 2010.
On October 13, 2009, the Mega Millions consortium and Multi-State Lottery Association (MUSL) reached an agreement in principle to cross-sell Mega Millions and Powerball in American lottery jurisdictions, with the two groups referred to as the "Mega Power Lottery" by many users. The expansion occurred on January 31, 2010, as 23 Powerball members began selling Mega Millions tickets for their first drawing on February 2, 2010; likewise, 10 Mega Millions members began selling Powerball tickets for their first drawing the next day. Montana (joining Mega Millions on March 1, 2010) was the first jurisdiction to add either game after the cross-sell expansion. Nebraska (March 20, 2010), Oregon (March 28, 2010), Arizona (April 18, 2010), Maine (May 9, 2010), Colorado and South Dakota (the latter two on May 16, 2010) also have joined Mega Millions since the expansion.
The conditions for Florida joining Powerball included a move of the live drawings from Iowa to Universal Studios in Orlando. The three hosts rotating announcing duties from Universal Studios were Tracy Wiu, Elizabeth Hart and Scott Adams (MUSL headquarters remained in Iowa, where its other draws are held). The wheel that was used to determine the Power Play multiplier was retired when the drawings moved to Florida; a random number generator (RNG) was used until the 2012 format change.
The largest Mega Millions jackpot, advertised as $640 million at the time of the drawing (annuitized) or $462 million (cash value), was drawn on March 30, 2012. The initial estimate for that drawing (following the March 27 drawing, which was $363 million annuity) was $476 million (later increased to $500 million and again to $540 million); brisk ticket sales pushed the jackpot values, both annuitized (to $656 million) and the cash option ($474 million) higher. The amount spent on Mega Millions for drawings following its previous jackpot win, on January 24, 2012, was at least $1.5 billion. three jackpot-winning tickets had been confirmed (Illinois, Kansas, and Maryland).
In March 2009, it was reported that New Jersey, already a Mega Millions member, sought permission to join Powerball. Shortly after, discussions were revealed about allowing each US lottery to offer both games. On Oct 13, the Mega Millions consortium and MUSL reached an agreement in principle to cross-sell Mega Millions and Powerball. In Nov, MUSL signed an agreement to start streaming Powerball drawings online.
The Mega Millions world record stood until January 2016, when Powerball took over the crown as the lottery champion of the world with a $1.568 billion jackpot. Changes to the Mega Millions game format have made it more difficult to win the Mega Millions jackpot and as a result, Mega Millions could soon award a record-breaking jackpot and regain its title as the biggest lottery in the world.
And of course, if non-US residents are eligible to buy the tickets, they are also eligible to claim the prize money should they win. However, be aware that the rules covering taxes and withholding vary depending on where you live. Countries outside of the United States might have different procedures. If you do win, be sure to consult with a tax professional for more information.
Wednesday’s jackpot might have been the second-biggest, but many expected it to actually surpass that $1.6 billion record if that lucky Massachusetts ticket-holder hadn’t hit on the right numbers. That’s because of what Kelly Tabor, a spokeswoman for the Colorado Lottery, calls “jackpot chasers,” casual players who rush out to buy a ticket when the jackpot gets big enough.
Under the current version's regulations (which began October 28, 2017 with the first drawing October 31) for Mega Millions, the minimum Mega Millions advertised jackpot is $40 million, paid in 30 graduated yearly installments, increasing 5 percent each year (unless the cash option is chosen; see below for differences by lotteries on cash/annuity choice regulations.) The jackpot increases when there is no top-prize winner (see below for information on how the Mega Millions jackpot is funded.) As of December 13, 2017, there has yet to be a jackpot winner under the current Mega Millions format, including wagers for the newly created Just the Jackpot option.
*a tip to know whether the website you are looking at actually buys lottery tickets online or follows the insurance model is to check the wording that they use. If you see the words “Play” then you can be confident it is a company that has agents and buys your tickets physically, if you see the words “Bet” you can be sure it is following the insurance model and you are placing a bet on the outcome of a lottery.
