Bracket strategy, first-round upsets and the best tournament promos.

Next edition · Updated

March Madness is a three-week, single-elimination sprint of 67 games that produces more betting volume than any event outside the Super Bowl. The neutral-site format and the talent gap between conferences make it the richest upset market of the year, which is exactly why books run aggressive tournament promos to capture the surge in sign-ups.

Two things separate March Madness from regular-season college hoops: brackets and pace. Filling out a bracket is a bet of its own, and the compressed schedule means totals and live betting move fast as tired teams play on short rest. Shopping lines across books matters more here than almost anywhere, because no book can sharpen 67 games at once.

March Madness bet types explained

The markets you will see for the March Madness, and what each one asks you to predict.

Point spread
The handicap on the favorite in a single game. Neutral courts remove home advantage, so tournament spreads behave differently than the regular season.
Moneyline
A straight pick of the winner — the home of the upset bet, where a 12-seed over a 5-seed can pay a long price.
Total (over/under)
Combined points over or under the number. Tempo and nerves swing tournament totals more than people expect, especially in the first round.
Bracket / advancement futures
Bet a team to reach the Sweet 16, Final Four, or win the title outright. A way to back a longshot before the field thins.
Round / region props
Markets like the number of double-digit-seed upsets in the first round, or which region produces the champion. Tournament-only fun bets.

How to bet the March Madness: beginner tips

  • Claim a tournament welcome offer before the first round — the largest promos of the college season land in mid-March.
  • Do not blindly back favorites. Double-digit seeds win first-round games every year; the upset moneyline is where the value hides.
  • Watch for tired teams. A squad that survived an overtime thriller is a fade candidate two days later on a short turnaround.
  • Treat your bracket and your bets separately — a chalk bracket and a few well-priced upset moneylines can both be smart.
  • Line-shop hard. With dozens of games on a single day, soft numbers are everywhere; compare two or three books before betting.

March Madness seeding trends

Decades of tournament results make seed performance one of the most studied datasets in betting. A handful of trends repeat almost every year.

  • A 16-seed has beaten a 1-seed only twice in tournament history — the top line is the safest in the bracket, but not invincible.
  • The 12-vs-5 matchup is the signature upset: a 12-seed wins roughly one in three of those games, making it the most reliable upset angle.
  • A 1-seed has won the national title far more often than any other line, and at least one 1-seed reaches the Final Four in most years.
  • Double-digit seeds reach the Sweet 16 nearly every tournament, rewarding bettors who price in first-weekend chaos.

March Madness betting FAQ

What is the best sportsbook for March Madness betting?
DraftKings and BetMGM offer the deepest tournament coverage, including bracket futures and round props, with FanDuel and Caesars strong on pricing and boosts. Most books run their biggest college-basketball promos in March, so compare current offers before signing up.
How do I bet on first-round upsets?
The simplest way is the underdog moneyline — a straight bet on the lower seed to win the game. The 12-vs-5 matchup is the classic upset spot, but any double-digit seed catching a tired or overrated favorite can offer value.
Can I bet on my entire bracket at a sportsbook?
A traditional bracket pool is a separate contest, but sportsbooks offer advancement futures that let you bet individual teams to reach the Sweet 16, Final Four, or win the title — effectively betting your bracket one team at a time.
Why are March Madness totals so hard to predict?
Neutral courts, tournament nerves, and short rest between games push tempo and shooting in unpredictable directions. Books cannot sharpen all 67 games equally, which is why line shopping on totals pays off in March.
