The 15-year-old midfielder is regarded as one of the top prospects in the country, and a number of clubs have been tracking him.
But now he is set to join the Toffees in a deal which could eventually be worth £2million to the Bantams.
Bradford City's head of football development Archie Christie confirmed to the Telegraph & Argus that the deal had been agreed.
"This is one of the highest deals ever for a 15-year-old from a League Two club," he said.
"But George is the best I've seen in his position at his age. He could become another Wayne Rooney or Paul Gascoigne."
Tottenham were particularly keen after the teenager scored a first-half hat-trick for them in a trial game against Aston Villa 10 days ago.
