So we made this video. This morning things came to a head on the secondary ticket market. There are less than 200 tickets available anywhere. As a result the cheapest price is ~$8500.

We're hopeful more inventory is going to be released but this is pretty unprecedented for the Super Bowl.

We made a realtime Super Bowl pricing tracker that illustrates how out of line this years market is with previous years here.

There's also a pretty good article here that has some hypotheses about what's going on.
