US jurisdictions with Powerball (red), Mega Millions (blue), or both (pink) as of November 2011. Note: the District of Columbia and the US Virgin Islands offer both games.

The 2010 expansion of Mega Millions and Powerball

On October 13, 2009, MUSL and the Mega Millions consortium signed an agreement to allow US lotteries to sell both games, no longer requiring exclusivity. The expansion occurred on January 31, 2010, as 10 Mega Millions members began selling Powerball tickets for their first drawing on February 3; simultaneously, 23 Powerball members began offering Mega Millions tickets for their first drawing on February 2. On March 1, Montana (by joining Mega Millions) was the first jurisdiction to join the "other" game after the cross-selling expansion. Later in March, Nebraska, then Oregon, also joined Mega Millions; Arizona followed on April 18, with Maine joining Mega Millions on May 9. Colorado and South Dakota joined Mega Millions on May 16. The most recent MUSL member joining Mega Millions is Louisiana, in November 2011. Mega Millions and Powerball each are played in 44 jurisdictions; 43 offer both games. (California offers only Mega Millions, while Florida has Powerball.)
