The next March Madness is the first with 76 teams: the 2027 men’s tournament starts on Tuesday, March 16, 2027, and ends with the Final Four at Ford Field in Detroit on April 3 and 5. Michigan won the 2026 title, beating UConn 69-63 in the national championship game in Indianapolis on April 6, 2026.
This guide covers how the bigger bracket works, the bets the tournament offers, and the numbers worth reading before you bet a game.

How the 76-team bracket works
The field grows from 68 teams to 76 in 2027. Every conference still gets one automatic bid, and the committee picks the best at-large teams to fill the rest, which adds eight at-large places.
The old First Four becomes the March Madness Opening Round: 12 games instead of four, on the Tuesday and Wednesday after Selection Sunday, at UD Arena in Dayton and InTrust Bank Arena in Wichita. The 12 lowest-seeded automatic qualifiers play six of those games, and the 12 lowest-seeded at-large teams play the other six. The 12 winners join the round of 64.
From there the calendar is the one bettors know: the round of 64 on Thursday and Friday, the round of 32 on Saturday and Sunday, then the regionals, the Final Four and the final.
2027 dates and sites
| Round | Dates (2027) | Sites |
|---|---|---|
| Opening Round | March 16-17 | Dayton, OH; Wichita, KS |
| First and second rounds | March 18-21 | Pittsburgh, Omaha, Fort Worth, Spokane, Charlotte, Minneapolis, Louisville, Sacramento |
| Final Four | April 3 and 5 | Ford Field, Detroit |
The Final Four moves to Allegiant Stadium in Las Vegas in 2028 and back to Lucas Oil Stadium in Indianapolis in 2029.
The bets March Madness offers
Point spreads are the main market. If Duke is -7.5 against a 12 seed, Duke has to win by 8 or more; the underdog side wins if it loses by 7 or fewer or wins outright. Both sides usually cost -110, which needs a 52.4% win rate to break even.
Moneylines are bets on who wins. Tournament underdogs pay well: a 12 seed at +250 needs to win only 28.6% of the time for the price to be fair. Our guide to moneyline betting has the arithmetic.
Totals, player props and live bets work as they do in the regular season. Futures cover the champion, each region, and the Final Four.
Bracket contests are a different game from betting: you pick every round in advance, and one early upset can end a bracket. Our March Madness bracket betting guide covers them.
The 2027 title market
DraftKings, through ESPN, already prices the 2027 national title:
| Team | Price | Implied chance |
|---|---|---|
| Florida | +600 | 14.3% |
| Duke | +600 | 14.3% |
| UConn | +1100 | 8.3% |
| Illinois | +1400 | 6.7% |
| Texas | +1800 | 5.3% |
| Michigan State | +1900 | 5.0% |
Michigan, the defending champion, is +2700. The 100 prices add up to 145.6%, so the book’s margin on this market is more than 45 points. A futures bet is worth making only when you rate the chance higher than the price does, and at that margin most prices on the board are not.
Numbers worth reading before you bet a game
KenPom’s adjusted efficiency ratings rate every team by points scored and allowed per 100 possessions, adjusted for opponents. The gap between two teams’ ratings is a quick check on whether a spread is roughly right.
The four factors explain where a team’s efficiency comes from: effective field goal percentage, turnover rate, offensive rebounding rate and free throw rate. A team that wins on offensive rebounds plays differently from one that wins on shooting, and that matters against a specific opponent.
Tempo sets the total. Two teams that play slowly produce fewer possessions and fewer points, so a total that looks low may be the right number.
Strength of schedule separates a 28-4 record against weak teams from a 22-10 record in a strong conference. Seeding tries to account for it, and the gap between the seed and the efficiency rating is often where a tournament price is off.
Tips for tournament betting
Shop between books: in a 12-game Opening Round and a 32-game first round, lines differ, and half a point on a spread is worth more over a tournament than most tips.
Travel and venue matter. First- and second-round sites are spread across the country, and a team playing near home can have a crowd edge.
Watch the lines move. A spread that moves a point or more without injury news means money has come in on one side, and the number you wanted may be gone by tip-off.
