Greg Skidmore, Brandon Lacoff and Tim Davidson came forward as trustees for The Putnam Avenue Family Trust, which they formed after Davidson bought the winning ticket at a Stamford gas station.
At least two of them live in Greenwich, one of America's wealthiest towns.
They will take the after-tax lump sum of nearly $104 million in cash. They say a significant portion will go to charity.
Davidson bought the $1 quick pick ticket for the Nov. 2 drawing at the Shippan Point BP gas station in Stamford. It was the only ticket he bought. The winning numbers were 12-14-34-39-46, Powerball 36.
The jackpot was the largest ever won in Connecticut and the 12th biggest in Powerball history.
The three men work at a small, startup asset management firm called Belpointe LLC in Greenwich. They appeared with their lawyer at a news conference and didn't say much.
"It feels good," Skidmore said.
Lottery officials had used billboards across the state to urge the ticket holder to come forward as the weeks went by without a winner.
Ranjit Singh, the gas station manager, said lottery officials called the station at about 10:30 a.m. Monday to announce that the winning ticket had been sold there. The station receives $100,000 for selling the winning ticket.
Singh said he didn't know the winners and doesn't remember selling the winning ticket.
"We're really happy," Singh said. "Christmas is a little early."
