How to bet on the NBA: moneyline, spread, totals and props
The NBA is the easiest league to start betting on and one of the hardest to beat. Every game has a full board of moneylines, spreads, totals, quarter lines and player props, and the lines are sharp because so much money moves on them. This guide explains how to bet on the NBA market by market, how overtime changes settlement, which rules to read first, how to compare prices between books, and where Canadians can bet legally.
Prices in the examples are illustrative. They show how each market works, not what a book is offering on a real game.
When is the 2026-27 NBA season?
According to the NBA's key dates, the 2026-27 regular season opened on 20 October 2026 and ends on 11 April 2027, with every team playing 82 games. Other dates that move betting markets:
| Event | Dates |
|---|---|
| NBA Cup group play | 30 October to 27 November 2026 |
| NBA Cup quarterfinals and semifinals | 4 and 5 December; 8 and/or 9 December |
| NBA Cup championship | 11 December 2026, Indianapolis |
| Trade deadline | 11 February 2027 |
| All-Star weekend | 19 to 21 February 2027, Phoenix |
| Play-In Tournament | 13 to 16 April 2027 |
| Playoffs begin | 17 April 2027 |
Only 80 of each team's 82 games were on the original schedule. The last two depend on NBA Cup results and are played between 4 and 10 December, so a few lines appear later than the rest.
Which NBA rules matter for betting?
The NBA rulebook sets each quarter at 12 minutes and each overtime period at five minutes. If the score is tied after the fourth quarter, play resumes after a short break and overtime periods continue until there is a winner. A regular-season NBA game cannot end in a tie.
For bettors, the key line in any book's basketball rules is whether a market includes overtime. BCLC's PlayNow game conditions are a useful published example: all game markets include overtime unless stated otherwise, second-half markets include overtime, and quarter markets count only points scored in that quarter, so overtime does not count toward the fourth quarter. PlayNow also requires at least 43 minutes of play for NBA bets to have action. Other books write their own rules, so check yours.
How does the NBA moneyline work?
The moneyline is a bet on who wins the game, overtime included. Say the home team is -250 and the away team is +205.
| Bet | Stake | Profit if it wins | Total return |
|---|---|---|---|
| Home -250 | $50 | $20.00 | $70.00 |
| Away +205 | $20 | $41.00 | $61.00 |
The implied probabilities are 250 / 350 = 71.4% and 100 / 305 = 32.8%, a total of 104.2%. Those 4.2 extra points are the book's margin. Heavy NBA favourites can be priced at -500 or more, where you risk a lot to win a little. Our odds explained guide covers the conversion in detail.
How does the NBA point spread work?
The spread is the most popular NBA bet. The favourite gives points and the underdog gets them. If the line is home -6.5 and away +6.5, both at -110:
| Final margin | Home -6.5 | Away +6.5 |
|---|---|---|
| Home wins by 7 or more | Wins | Loses |
| Home wins by 1 to 6 | Loses | Wins |
| Away wins | Loses | Wins |
At -110 you stake $22 to win $20, so a winning bet returns $42. With -110 on both sides, each side implies 52.4%, so you need to win more than 52.4% of these bets to break even. A whole-number spread such as -6 can land exactly, which is a push and returns your stake.
Are there key numbers in the NBA?
Not in the way football has them. NBA teams score more than 100 points a game in steps of one, two and three, so final margins spread out widely and no single margin carries the weight that 3 and 7 carry in the NFL. Late fouling does push some margins around, because a trailing team fouls to stop the clock and the leader adds free throws. Half a point still matters on any spread, so compare the line as well as the price.
How do NBA totals work?
A total is a bet on the combined points of both teams. Suppose over 228.5 is -110 and under 228.5 is -110. Overtime counts on full-game totals at most books, and it changes a lot:
- The game finishes 112-110 in regulation. That is 222 points, so the under wins.
- The game is tied 110-110 after four quarters and ends 121-118 in overtime. That is 239 points, so the over wins.
A five-minute overtime usually adds enough points to move a total several baskets, so unders are the bets most exposed to close games. Team totals (one team's points only) work the same way.
Can you bet on NBA quarters and halves?
Yes. Most books post lines for the first half, second half and each quarter:
- First half. A spread, total and moneyline covering the first two quarters only.
- Second half. Usually includes overtime, as in PlayNow's rules.
- Quarter lines. Usually exclude overtime, so a fourth-quarter over does not get help from extra time.
- Race to points. For example, first team to 20 points, often offered live.
Half and quarter moneylines can end tied. On a two-way market, a tie is normally a push, but some books offer three-way lines where the tie is a separate outcome.
What NBA player props can you bet?
Player props settle on one player's official stats, not the result.
| Prop | Example line | Notes |
|---|---|---|
| Points | Over 24.5 at -115 | Includes free throws and overtime at most books |
| Rebounds | Over 8.5 at -110 | Offensive plus defensive |
| Assists | Under 6.5 at -105 | Official scorer decides |
| Three-pointers made | Over 2.5 at +120 | Made threes only |
| Points, rebounds and assists | Over 38.5 at -110 | Combined total |
The common pitfall is minutes. NBA teams rest players and announce late scratches, and props are priced on expected minutes. Under PlayNow's conditions, a player must be dressed and see court time for a bet to have action, and if a player takes no part, all selections on that player are void. A player who plays three minutes and leaves injured still counts, and the bet settles on those three minutes. Other books may differ, so read the player prop rules.
Props are popular in same game parlays, where the legs are related and the pricing is not a simple product. See our guide to parlays and same game parlays before you build one.
Betting on the Raptors
Toronto is Canada's only NBA team, and the Raptors' schedule release lists the home opener on 21 October 2026 against Chicago and the road debut on 23 October in Washington. Their NBA Cup group games are at home to Orlando on 30 October, at Milwaukee on 6 November, at Detroit on 20 November and at Brooklyn on 27 November. The original schedule had 40 home and 40 away games, with two more set for 4 to 10 December, and the last regular-season home game is on 7 April against Brooklyn.
Betting on your own team is fine as long as you bet the price, not the jersey. If you only ever back the Raptors, you will take some prices you would skip on any other team. Comparing lines makes that visible.
How do you shop for the best NBA line?
NBA lines are close between books, but not identical, and small gaps add up over a season. Take one hypothetical game where Toronto is +6.5 at two books:
| Book | Raptors +6.5 | Opponent -6.5 | Overround | Fair Raptors price |
|---|---|---|---|---|
| Book A | -110 | -110 | 104.8% | +100 |
| Book B | -102 | -118 | 104.6% | +107 |
A $100 winning bet on the Raptors pays $90.91 profit at Book A and $98.04 at Book B, on the same line. Enter both prices from each book in our no-vig calculator to see the overround and the fair price. If the price you can get is above the fair price at most books, you have found the better number. Our parlay calculator does the same job for combined bets.
Line shopping only works if you have accounts at more than one book, and in most provinces the only provincially authorized option is the lottery corporation's site. That is where the legal options below matter.
Where can you bet on the NBA in Canada?
Every province offers NBA betting through its lottery corporation, and Ontario and Alberta also allow registered private books.
| Where you are | Provincial option | Private regulated books |
|---|---|---|
| Ontario | PROLINE+ from OLG | Yes, registered with the AGCO |
| British Columbia | PlayNow Sports from BCLC | No |
| Quebec | Mise-o-jeu+ from Loto-Québec | No |
| Alberta | PlayAlberta | Yes, since 13 July 2026 |
| Manitoba and Saskatchewan | PlayNow, plus Sport Select at retail | No |
| Atlantic provinces | ALC.ca | No |
OLG says PROLINE+ caps a single bet at $50,000 and does not accept bets that would pay more than $1,000,000. PlayNow requires you to be 19, a B.C. resident and physically in British Columbia, and its sports list includes NBA basketball. For Ontario's private market, our Ontario page explains how to check whether a book is registered. Our guide on whether sports betting is legal in Canada covers every province.
Offshore crypto books are the other route Canadians use. They sit outside every provincial market and are not connected to provincial self-exclusion. In our reviews, Duelbits and Grailbet have NBA links in their sports menus, TonyBet lists pre-match and live NBA markets, and Stake and Shuffle list the NBA in their sportsbooks.
