Setting Expectations for March Madness Bracket Pools

If you want to get the most out of March Madness brackets, you need to understand what you are up against, and the chances of winning bracket pools.

by Jason Lisk - Feb 17, 2026

We always hope our March Madness Bracket Pool picks will succeed due to hard work, sound analysis, and luck.

Just remember — it certainly doesn’t happen every year. This is a long-term game. The great thing about bracket pools is that you can give yourself a considerable edge to win. The bad thing about bracket pools is that you must beat many opponents, so the odds are still pretty long, and you only get one shot each year.

When competing against tens, hundreds, or thousands of people in a bracket pool, even with the smartest picks going in, you’re never expected to win. We don’t sugarcoat reality here; that’s just probability. If you have one entry in a 100-entry pool and you’re four times as good as everyone else, you’re still only expected to win first place in that pool about once every 25 years.

Should you still play? If you like making money and are willing to think long-term, yes. Over time, the expected profits on your pool entry fees with an edge like that should be fantastic. But it’s certainly not a get-rich-quick scheme unless you get lucky, score your first win early, and stop playing.

The Average Success Rate of March Madness Brackets

March Madness Bracket Contests come in all shapes and sizes. Still, the general reality is that the number of payout spots will be less than half the number of entries.

Based on data reported by our subscribers since 2015, the average chance a random single entry would win a prize in a given pool was 7%.

Let’s dive a little deeper into some specific examples:

• The most frequent pool size is between 11 and 30 entries; an average of 14% of entries received a prize (one winner, top 3-4 places paid).
• If you were to play one entry in a 30-entry pool with that payout structure for 30 years (with no edge over your opponents), you should expect to win first place once and qualify for any prize in four of the 30 years.
• If you play in the largest pools, the odds of winning a prize drop even more sharply. Since 2015, in pools of 10,000+ entries or more, only about 3% of entries qualified for a prize on average.

So, the base expectation should be that winning money is a pleasant surprise and not guaranteed. Our goal is to increase our subscribers’ chances so that they win more than expected over time. But we also know and respect that taking down a prize in any pool requires both skill and luck.

How PoolGenius Helps: Our Track Record

Our recent performances show both the value our advice can provide and the volatility of playing in bracket contests, where predicting winners through six rounds of action involves lots of risks.

Over the last seven tournaments, our results had ranged from 19% of subscribers winning a prize (when Baylor defeated our most common recommendation, Gonzaga, in 2021) to 90% of subscribers winning (in 2017, when our most frequent recommendation was North Carolina over Gonzaga).

Here’s the yearly percentage of our subscribers who reported winning a prize in their pool:

• 2025: 51%
• 2024: 58%
• 2023: 48%
• 2022: 19%
• 2021: 19%
• 2019: 71%
• 2018: 63%
• 2017: 90%

Over the last seven tournaments, the average has been 52% of our subscribers winning a prize in at least one pool.

You can see full recaps of our picks, what went right and what did not, and how they did in 2017, 2018, 2019, 2021, 2022, 2023, 2024, and 2025.

We hope to maintain that overall performance, but our performance is bound to fluctuate year to year.

Our most frequent NCAA champion recommendation won the title three times in the last eight years. Seven of the previous 15 teams that were our most frequent recommendations for the title game made it that far. Even according to our projections, none of those teams were 42% likely to win the title. So we know getting that kind of result, even if we have excellent analysis and predictive numbers for tournament teams, is not guaranteed.

Different Rules & Scoring Leads to Competing Picks

In addition, the algorithms we’ve developed now customize bracket picks for many different scoring systems, several of which have radically different scoring structures (e.g, huge upset bonuses vs. no upset bonuses).

So, our brackets for the two types of pools can look very different. That usually means that when a portion of our customers’ picks are doing great (say, if lots of favorites are winning), some other portion of our customers’ picks probably aren’t doing so great (say, if they’re in upset bonus pools with really aggressive picks).

We can also have different risk/value picks for different pool sizes. For example, in 2023, Houston was our most common champ pick in small pools, so when they were upset in the Sweet 16, that sunk many smaller pools. But Connecticut was a champ pick in some brackets as the pool sizes got larger, so we saw higher win rates in larger pools in 2023.

Then, last year, it was the reverse, with our most common pick, Connecticut, being more heavily used in smaller pools, while larger ones took on more risk with picks that flamed out, like Auburn.

Because of this, it’s almost guaranteed we’ll never have a March Madness where all our paying customers walk away thrilled. That’s a bummer because we want all our customers to be thrilled with PG. Unfortunately, it’s just the nature of this business. The value in the analysis should help you win more often than expected in the long run. It’s always great to be hopeful, but being realistic is just as important.

The Key to Long-Term Success in Winning Bracket Pools

We discussed how you can treat bracket contests like the stock market and turn excellent profits over time. If you’d like to profit from bracket pools, and you’re a rational human being, you’ve got two options:

1. Trust the Process and Keep Playing

Bracket pools are a beatable game, but the odds of winning in any given year are low. Stick with our picks for the long term, and hopefully, you will win your 30-entry pool once every 10 years instead of once every 30 years, which is the baseline expectation.

Since 2015, when we started our customized picks product, subscribers in 11-30 person pools have won a prize 3x as often as expected, directly on that pace.

2. Play More Brackets Each Year

You must play more brackets if you’re hell-bent on increasing your chances of tasting victory more often.

You’ll technically sacrifice a bit of your edge. After all, as Highlander says, THERE CAN BE ONLY ONE Best Bracket for a given pool. The next-best bracket you play in that pool is, by definition, at least a little bit worse.

However, the expected returns of playing 2+ brackets in a pool can still be quite good, and our alternative brackets diversify your risk by making different key “bets” in each one. It’s much more fun when you have many other dogs in the fight.

David, our resident bracket maniac, plays about 30 brackets each year in various pools with different scoring systems. You don’t necessarily need to be as crazy as him, but many of our customers play two to five brackets annually.

Playing multiple types of brackets can also diversify and let you catch the best-performing type of pool over the years.

From Amateur to Winner: PoolGenius + Multiple Brackets

Suppose you’re a new subscriber or remain unconvinced about PoolGenius after using our picks and not winning anything. In that case, it’s probably best to listen to one of our long-term customers, who also touches on the dynamic of playing multiple brackets.

He sent us this email after the 2016 tournament:

I’ve been using [PoolGenius] for a few years now. Don’t remember how many. However, each and every year since the late eighties I’ve participated in an NCAA March Madness Pool that’s grown to about 100 entries per year. It includes astute players from many states.

Me I’m a rank amateur. I hardly ever watch any of the NCAA Men’s basketball games leading up to the tournament. The only reason I even watch the games beginning with the Sweet Sixteen is — after using [PoolGenius] I might add — I’m always in the running to at least place or show. So, as it goes, it’s more enticing to watch a game if one has skin in the game.

Let me qualify. I don’t do just one pick. Generally, I’ll throw five to seven entries in the 100-entry pool. It pays five places win, place and show. That said, the results over the past four years defy the odds. I won this March Madness Pool in 2016 picking UNC over Villanova. (Only one picked Villanova to win; he placed fifth.) And I won it all with Louisville in 2013.

So, participating in this 100-entry Madness Pool for over 30 years, and placing multiple entries each year, one of those WON it outright two out of the past four years. To put this into perspective, before [PoolGenius], I may have placed or showed up in the top 5, but split sharing a win only once in over 30-years, I think 1987 or 1988. Wow. What a difference [PoolGenius] has made.

He sent another update after the 2018 tournament, telling us that one of our brackets finished 5th and cashed. In 2017, one came in 3rd place and cashed. That made it three straight years that he had won a prize in his 100-entry pool using our brackets, plus two first-place wins in the last seven years.

Playing multiple brackets is a numbers game. The years you don’t win, you take a much bigger hit, and some years, a 3rd or 5th-place finish may or may not win back your investment. But if you think you have a significant edge, especially in larger pools, you may not want to wait for 10, 20, or 30 years for that edge to manifest itself in the form of a pool win.

Exploring Our Track Record & Beyond

We’re confident we’re delivering value with this bracket picks service, and we’re happy to say that we’ve also compiled and published the data substantiating that claim on our “Past Performance” page.

If you want to see some of what we deliver, you can look through our reviews of 2017, 2018, 2019, 2021, 2022, 2023, 2024, and 2025 picks, and can also see examples of some of the past write-ups that we provide to our subscribers in the days leading up to the tournament each year.

When those overall stats about winning bracket pools apply to you, it will depend on how lucky you get during your first few years as a customer. It may take more patience to reap the rewards than many people are willing to commit.

We understand that, but there’s nothing we can do to change that. We keep on doing the best analysis we can and working to improve our methods year after year.
