Lottery officials in the eastern US state of Maryland said Monday that a winner had come forward to claim his or her share of the record US$656 million (NZ$799.5 million) Mega Millions jackpot.
Maryland lottery director Stephen Martino was to hold a press conference in Baltimore on Tuesday "to provide details about the winning ticket," officials said.
A lottery spokeswoman told The Baltimore Sun that the winner - who purchased the ticket at a 7-Eleven convenience store in Baltimore County - wished to remain anonymous, but a "storyline" would be shared with the public.
A 37-year-old Haitian-born mother of seven who claimed last week that she held Maryland's winning Mega Millions ticket later told a Washington television station that she had "misplaced" it.
Two of the three winning tickets in the March 30 drawing have now been confirmed.
