March Madness is coming. That means Fantasy League Commissioners, Lottery Bonus Ball organisers and other office pools aficionados across the country are starting to print off brackets for friends and colleagues to enter.

Those entering vary. From those with zero basketball knowledge who simply select their favorite school (based on who they knew that went there) in every match-up, to those who have been researching March Madness picks and predictions and subscribing to NCAA Tournament newsletters since January.

Both types of people will be dreaming of a perfect March Madness bracket. However, it may be better to lower expectations after statisticians have revealed that the odds of predicting a perfect bracket are a massive 9,223,372,036,854,775,808 to 1.

March Madness Perfect Bracket Odds

That number, which is larger than any that the average non-mathematician has seen written down before, is 9.2 QUINTILLION.

So, here’s the breakdown for all you maths heads out there.

Raise the number of outcomes for a game (2) to the power of the number of games in the tournament (63). There are 64 teams, which means 63 games to find a winner (disregarding the First Four teams in action before Round One):

2^63 = 9,223,372,036,854,775,808

That’s madness…right?

What is a Quintillion?

A Quintillion is a number with 18 zeros. It’s one billion times one billion.

To put the size of that number into context, there are 8 billion people in the world. Imagine if we rounded up slightly and said that there are ALMOST 9.2 billion people in the world. This would mean that everyone on the planet would have to submit one billion March Madness bracket entries in order to cover all eventual outcomes. Yes, it’s that crazy.

It is for this reason that legendary financier Warren Buffett was quite happy to offer $1 billion to anyone who completed a perfect March Madness bracket. He knew the odds were still hugely in his favor.

9.2 Quintillion Compared to Other Measurements

To put that 9.2 quintillion number into some context, here are some comparisons:

  • The smallest standard unit of time is one second. So, 9.2 quintillion seconds is 21 times the age of our universe.
  • The smallest standard unit of money is one penny. Therefore, 9.2 quintillion pennies is 858 times the total world economy.
  • The smallest standard unit of distance is an inch. So, 9.2 quintillion inches is 5.8 billion times the circumference of earth.

What Is More Likely Than A Perfect March Madness Bracket?

Here is a list of things that are statistically achievable and billions of times more likely than a perfect March Madness bracket:

  • Bowling a perfect game (odds of 1 in 11,500)
  • Dating a supermodel (odds of 1 in 880,000)
  • Making an albatross at golf (odds of 1 in 1 million)
  • Dying from tap water (odds of 1 in 5 million)
  • Dying from being left handed and using a right handed product incorrectly (odds of 1 in 7 million)
  • Having identical quadruplets (odds of 1 in 15 million)

Yes, giving birth to these four is incredibly more likely than achieving the perfect March Madness bracket.

Perfect March Madness Bracket Odds

But, this shouldn’t discourage you from entering March Madness brackets as there has never reportedly been a perfect bracket achieved.

$1 billion may not necessarily be attainable during March Madness, but the average person apparently hits about a 72-75% perfect March Madness bracket. There are just too many random upsets to call. So, if you can go above that then you will probably come close to winning your office pool.
