What is a moneyline bet?
A moneyline bet is the simplest wager: pick which team wins. The price reflects how likely each outcome is. Favorites carry negative odds (you risk more to win less); underdogs carry positive odds (you risk less to win more).
Moneylines are most common in baseball, hockey, and soccer, where margins are small and spread betting is rare. The key trap is overvaluing large favorites — a -300 team must win 75% of the time just to break even, and most bettors dramatically underestimate how often favorites lose.
How does a point spread work?
A point spread handicaps the game by adding or subtracting points from the final score. The favorite gives points (−3.5 means they need to win by 4 or more); the underdog gets points (+3.5 means they win outright or lose by 3 or fewer).
Spreads are priced at or near -110 on both sides, so both sides carry roughly equal juice. The spread moves as money comes in — a line that opens at −3 and climbs to −5 has attracted heavy public action (or sharp money) on the favorite. That movement itself is information.
Spreads are dominant in football and basketball where scoring margins vary widely. Half-point hooks (−3.5 vs −3) are significant because many games end on key numbers like 3, 7, and 10.
Totals (over/under): bet the combined score
A total is a bet on whether the combined score of both teams will be over or under a number set by the book. Like spreads, totals are usually priced near -110 on both sides.
Totals are driven by pace, weather, injuries (especially quarterbacks and starting pitchers), and venue. A rainy night game with two ground-ball pitchers is a natural under; a dome game between high-scoring offenses leans over. The total opens based on projected game conditions and moves as sharp money and public action arrive.
Which market offers the most value?
Sharp bettors tend to focus on spreads and totals in football and basketball because the large number of games per season creates a statistical foundation. Moneylines in baseball and hockey are popular for underdogs — a +160 team only needs to win 38.5% of the time to be profitable, and live underdogs tend to be more exploitable than their price implies.
The best market is the one where your information edge is largest relative to the current line. Game totals in particular receive less sharp attention than spread markets, making them one of the more overlooked soft spots on most boards.
How much does a $100 bet win at -150 or +130?
A $100 bet at -150 wins $66.67, and a $100 bet at +130 wins $130. For a minus price, divide 100 by the odds and multiply by your stake: 100 / 150 × $100 = $66.67. For a plus price, divide the odds by 100 and multiply by your stake: 130 / 100 × $100 = $130. In both cases a winning bet also returns the original $100.
Each price also sets a break-even win rate. At -150 you must win 150 / (150 + 100) = 60% of the time. At +130 you need 100 / (130 + 100) = 43.5%. Believing a favorite will win is not enough; you need to believe it wins more often than the price implies.
Expected value puts the two together. Suppose a +130 underdog truly wins 47% of the time. Over 100 bets of $100 you win 47 times for $6,110 and lose 53 times for $5,300. That is +$810, or about $8 per bet. The 3.5-point gap between your estimate and the break-even rate produced that profit.
Why does -110 mean you have to win 52.38% of your bets?
At -110 you risk $110 to win $100, so you need 110 wins in every 210 bets, which is 52.38%. Most spreads and totals carry that price on both sides. If the book takes $110 on each side of a game, it holds $220 and pays the winner $210. The $10 left over is its margin, 4.55% of the money wagered.
This is why picking half your games correctly loses money. Fifty wins at +$100 and fifty losses at -$110 net -$500 over 100 bets. The bettor split the picks evenly and still paid the margin on every loss.
Reduced juice lowers the bar. At -105 on both sides the break-even rate drops to 51.22%. That 1.16-point difference sounds small, but most real edges are only a few points wide. Shopping between books for -105 instead of -110 is the simplest way to get there.
What happens if the final score lands exactly on the line?
The bet is a push, and the book refunds your stake. A favorite at -3 that wins by exactly 3 pushes. So does an over/under of 44 when the teams combine for 44 points. Lines ending in .5, such as -3.5 or 44.5, cannot push. That is why half-point lines are so common.
A push in a parlay usually drops that leg, and the parlay pays at the shorter number of legs. Some products, such as certain teasers, grade a tie as a loss instead. House rules decide this, so read them before you bet.
Moneylines can tie too. An NFL regular-season game can end level after overtime, and most books refund two-way moneylines when it does. Soccer moneylines are usually three-way, with the draw as a separate outcome, and settle after 90 minutes plus stoppage time.
