These days it is not so uncommon to meet people who say they predicted Donald Trump was going to win well before the shock election.

One of the few people who can prove it though is the billionaire Australian businessman Anthony Pratt.

Mr Pratt, executive chairman of the paper and packaging giant Visy, had been spending a good bit of time travelling through his company's mills and plants in the US midwest - the very states that eventually turned the election for Trump. Everywhere he went his staff told him they were going to vote for the reality TV star.

Mr Pratt began predicting Trump was going to win, but he was worried that after the fact nobody would believe he had called it, so he did the obvious thing and dropped $100,000 on a Trump victory with the TAB, netting himself a cool $450,000 payout after the election.
