This competition (and the followup) is official for important conferences in the field, so I expect many teams to publish their results. In general there is lots of discussion, tips & tricks posted online during such competitons, both in Kaggle forums and in blogs. So the value is certainly more than that off the winner, and most of it is available to everyone, not just the sponsors.
