The Brexit champion claimed he will be fighting to form a Government by the end of the decade after enjoying a surge in support from young people.
Mr Farage said his party is doing "very well" among teenagers, warning that young men feel "emasculated" and are now rallying behind people they believe in.
And he declared: "British politics will break up in the next five years."
Warnings
Reform UK has been polling consistently alongside the Tories for several weeks, prompting warnings from Conservative strategists that Mr Farage will open the door to a Labour super majority.
The Tories have argued only one of two men can be PM tomorrow Rishi Sunak or Sir Keir Starmer.
But on his last day campaigning in Clacton, Essex, where he hopes to finally get elected as an MP, Mr Farage declared: "I believe in five years we will be serious challengers for government.
"Success is many millions of bridgehead votes and a in Parliament. How big or small that is, I don't know.
"But the important point for me is not just providing opposition to in Parliament. It's Starmerism for doing it in the country.
"Tomorrow is the first big step Reform. We've got to professionalise it. We've got to democratise it. But that is what I intend to do."
Asked what success will be tomorrow, Mr Farage would not confirm to the Daily Express how many seats he is targeting.
He added: "We know Labour are going to have a stonking majority.
"Parliament is where arguments are made, but it's in the country that you change things.
"My track record has been to build up grassroot movements.
"Twenty-five years ago I became an MEP, and I used that to build Ukip into quite a significant force. We'll do that again."
