The game show - which sees contestants answering questions to climb a cash ladder and has an unlimited jackpot - has been a hit since launching this year.
Announcing that it had been recommissioned, ITV said the show drew in 6.1 million viewers for its launch episode.
Ant said: “We are thrilled that Limitless Win has been a hit with the viewers and is coming back for more.
"We’re beyond excited to be able do it all over again and we can’t wait to find new contestants to play the first TV show with a limitless jackpot!”
Dec added: “We’re already preparing ourselves for another series of nail-biting drama, jeopardy and tension as we present more questions you can’t help but Google!
"We’re expecting more, and higher, dizzying climbs up the limitless money ladder."
"We can’t wait," he added.
Writing on Instagram, the presenters said: “Thank you so much for watching…
“We’ll see you for the last show of THIS series on Saturday.”
ITV teased that the last instalment of the current series will see one pair of contestants “climbing farther up the limitless money ladder than anyone has ever been before”.
Katie Rawcliffe, ITV Head of Entertainment Commissioning, said bringing the show back for a second run was “a no- brainer”.
“Ant & Dec’s Limitless Win has quickly become an audience favourite, with families up and down the country playing along from home - from searching their kitchen cupboards to identify the length of a Pringles tube to Googling the width of Michael Jordan’s handspan,” she said.
Ant & Dec’s Limitless Win concludes this Saturday at 8:30pm on ITV and ITV Hub.
