Sky Bet make Bradford 8/1 to secure back-to-back promotions after winning the League Two play-off final 3-0 against Northampton.
The Capital One Cup finalists are considered outsiders for the League One title at 28/1 with the likes of Wolves (9/2), Bristol City (7/1) and Peterborough (8/1) expected to be vying for returns to the Championship.
Saturday's triumph will increase the stock of Bantams boss Phil Parkinson even further, with the 45-year-old currently considered in the betting for the vacancies at Doncaster and Sheffield United.
Sky Bet Football Trader Chris Spicer said: "We expect Bradford to be one of the weaker sides in League One next season but, with momentum from the way they finished this campaign and some shrewd summer signings, they may just have a chance of mounting another promotion push.
"The big question now is whether they can keep hold of their highly-rated manager, with Parkinson likely to be a wanted man after an incredible campaign and already backed for various jobs after their impressive cup run.
"While becoming the next Sheffield United manager, which is a 40/1 chance, is not really considered much of a step up now Bradford have joined them in League One, the vacant position at Doncaster could offer more appeal, although he is 33/1 with Paul Dickov the odds-on favourite."
