If you’re thinking about placing bets this year, it's time to get your strategy nailed. Do you go for big names, big action, or is betting every underdog actually a profitable strategy?
It sounds tempting with every tournament offering the potential for delivering shocking upsets and massive payouts. But turning that chaos into consistent profit is a different story.
Let’s break down what really happens when you bet every underdog and what smarter bettors are doing instead...
Like most sports, March Madness is built on unpredictability.
Every year, lower-seeded teams knock out heavy favorites. With these moments dominating headlines and highlight reels, it's easy to create the impression that underdogs win all the time.
From a betting perspective therefore, the appeal of picking an underdog is obvious:
Bigger odds = bigger payouts
One upset can cover multiple losses
Early rounds are full of potential surprises
Landing a +800 or +1200 winner feels like cracking the code but the key question is: how often does that actually happen?
There are two main ways to look at underdog betting:
Historically, underdogs have actually performed slightly better than favorites against the spread in the NCAA Tournament. But the margin is tiny.
The edge is often less than 1% so sportsbook margins (vig) erase any advantage and results vary significantly year to year anyway.
In other words, there’s no reliable long-term edge here.
This is where most bettors focus as underdog moneylines offer huge returns. However, they win far less frequently.
Here's the problem:
You need multiple big upsets to stay profitable.
Most tournaments don’t deliver enough of them.
Losses accumulate quickly when favorites dominate.
A single deep Cinderella run can make the strategy look genius but without it, the numbers don’t hold up.
Consider these legendary moments:
Incredible? Absolutely. But these Cinderella stories are the exception, not the rule. When you remove these rare, high-paying upsets, betting every underdog typically results in a slow (and painful) bankroll drain.
Recent tournaments reinforce the same pattern:
The Round of 64 consistently produces the most upsets.
Double-digit seeds win multiple games each year.
Underdog bettors often start strong.
Favorites begin to take control.
Talent gaps become more obvious.
Underdog win rates drop sharply.
This creates a familiar cycle where there are early profits from surprise wins but gradual losses as the tournament progresses. The final outcome depends on whether a major upset run occurs. Most years, it doesn’t, but you never know!
The biggest issue with betting every underdog is simple: you’re relying on rare events to stay profitable.
Cinderella stories feel common because they’re so memorable, but they don’t happen often enough to build a consistent edge. Deep tournament runs from low seeds are relatively rare, and when they do happen, they’re difficult to predict in advance. Big odds wins might deliver eye-catching payouts, but they occur sporadically rather than consistently. On top of that, sportsbooks are well aware of how bettors think. They price markets to reflect public bias toward both favorites and longshots, which means the odds you’re getting aren’t as generous as they appear on the surface.
The result is a strategy that works against you over time. You end up overpaying for long odds, taking on steady losses as favorites win the majority of games, and ultimately relying on unlikely outcomes to recover your bankroll. And that’s not a sustainable approach. In fact, it's variance rather than a real strategy.
But that doesn’t mean underdogs should be ignored completely. It just means they should be used selectively and strategically.
Here’s what sharper bettors tend to focus on:
Targeted Matchups: Some underdogs are mispriced due to stylistic advantages, pace, or defensive matchups.
Experience & Coaching: Teams with veteran players or strong coaching often outperform their seed.
Market Overreactions: Public money can inflate favorites, creating value on the other side.
Instead of betting every underdog, the real edge comes from identifying the right ones.
