# The Yahoo! Sports \$60.85 Perfect Bracket Challenge

By Ben Blatt and Bobby Samuels

Every year, when March Madness comes around, numerous sites offer huge jackpots to anyone who can perform the most hallowed feat in sports betting: filling out a perfect bracket. The prizes can be staggeringly large: ESPN is offering \$1 million this year, and a few years ago Papa John’s promised to give away one million pepperoni pizzas. Oftentimes with large promotions, companies will instead pay a fixed fee to an insurance company who will be responsible for the actual payoff.  Although most companies don’t disclose if they did insure their grand prize, the question arises: How much money would Yahoo!, for instance, have to pay to insure its \$1,000,000 prize?

First, we need to find the odds of filling out a perfect bracket. This has already been studied at some length, so we’ll be as brief as possible here. If completed randomly, the odds of picking a perfect bracket are (1/2)63, or a mere 0.00000000000000001% chance. However, even someone filling out their office pool bracket after not watching a single game all season isn’t doing so completely randomly.  In order to create a baseline of how probable a reasonably filled out bracket is of being perfect, we filled out a bracket utilizing Ken Pomeroy’s rankings and computed the odds of perfection using his Pythagorean win expectation. The result: 1.2 x 10-11, or a 0.0000000012% chance.

Using this number, we can simply find the probability that at least one person in a large pool would fill out the bracket perfectly and then estimate the insurance on the prize. Of course, we don’t know the markup that an insurance companies would use, so we’ll just assume that they’re breaking even: that is, the amount paid to the insurance companies is equal to the expected cost of assuming the risk of the payout. Assuming the companies choose to use insurance (we don’t know if they did or not), below is what some of the competitions would have looked like:

Whether or not there is a winner, the insurance company will receive \$60.85, payable in 40 equal annual installments of \$1.52 each, without interest.

Interesting stuff. Good idea using the kenpom win probabilities.

I bet none of these sites even insure it.

I’d bet that any insurance company will be hugely risk averse to something like this so they would charge a big surplus. Then think about the overhead to process the insurance and these sites would be better off taking the risk themselves.

How about a time-value study on your payoff for filling out a bracket? Assume 30 mins to pick the bracket, knock off half for taxes and you’re at about 1 cent per hour, not subtracting anything for risk premium.
