Bagman loves gambling, which got him in financial trouble so severe that he pays some of his creditors (including Fred and George Weasley) with disappearing Leprechaun Gold, after they have gambled on the Quidditch World Cup. After the World Cup final, some goblins corner him in the woods outside the stadium and take all the gold he had on him, which is not enough to cover his debts. To clear his debts with the goblins, Bagman makes a bet on the Triwizard Tournament, of which he is one of the judges. He bets the goblins that Harry would win. He tries to help Harry over the course of the Tournament, giving him a perfect score in the First Task even though he is injured, and offering him advice. Harry and Cedric Diggory end up tying for first place in the tournament, and Bagman does not win the bet as the goblins argue that Bagman was betting Harry would win outright. Bagman runs away after the Third Task of the Tournament.
