Of the other wrestlers involved in the match Kevin Owens has the next best chances at +575, only a 15% probability. AJ Styles and Sami Zayn are not too far away from KO in their chances for winning at -600. Shinsuke Nakamura has odds of +700 and the dark horse, Dolph Ziggler has very slim chances at +2500. Putting Dolph's odds in perspective, a successful $100 bet would yield a massive $2500.
There are several other announced matches at Money in the Bank, however the men's MitB is the only one that has odds posted as of press time. They will most likely be posted the week of the event. It is rare for matches to have betting odds available this early in the game, but Baron Corbin was rumored to be winning it months ago, before any participants had even been announced, so there is precedent for setting these lines. The informed prediction would suggest that the odds will move even further in the direction of Corbin and right now could be the best possible bet anyone will be able to make on him before his odds get longer.
