The interim UKIP leader told ITV News that he "wasn't particularly surprised" at the likely result because "the political class is reviled across much of the west, the polling industry is bankrupt, and the press just hasn't woken up to what's going on in the world."
He added: "I thought Brexit was big, but boy, this looks like it's going to be even bigger."
Farage, who played a major role in the successful campaign for the UK to leave the European Union, travelled to America in August to speak at a Trump rally. Although he stopped short of endorsing the Republican candidate at the time, he has since been more open about his support, and spent a substantial amount of time in the US prior to the election.
Trump's likely success has also raised questions about the UK government's lack of a formal relationship with the likely new administration. The Spectator's political editor James Forsyth tweeted:
How does Theresa May's government deal with a Trump administration? Number 10, privately, admit they don't know him or his people

It raises the interesting prospect that Farage knows Trump far more intimately than Prime Minister Theresa May and her cabinet.
Farage, who is currently a UK member of the European Parliament, is reportedly eyeing a position in the Trump administration should his election to the presidency be confirmed.
