The longest an NCAA bracket has ever stayed perfect

The longest (verifiable) streak of correct picks in an NCAA tournament bracket to start the beloved March Madness tournament is 49, a mark that was established in 2019.

An Ohio man correctly predicted the entire 2019 NCAA tournament into the Sweet 16, something we've not seen in years of tracking publicly verifiable online March Madness brackets at all major games.

The absurd odds of a perfect NCAA bracket

As such, the number of possible outcomes for a bracket is 2^63, or 9,223,372,036,854,775,808. That’s 9.2 quintillion. In case you were wondering, one quintillion is one billion billions.

If we treated the odds for each game as a coin flip, that makes the odds of picking all 63 games correctly 1 in 9.2 quintillion. Again, this is not a completely accurate representation of the odds, as any knowledge of the sport or tournament’s history improves your chances of picking games. But it is one of the easiest to quantify, so let’s have some fun with it.
