Boston Celtics X Odds, Betting Lines and Futures Markets for 2026-27 Season
The Boston Celtics odds reflect a team that looks very different from the one that won 56 games last season. Jayson Tatum is back after returning from his Achilles injury in March, but Jaylen Brown is gone. Boston traded Brown to Philadelphia for Paul George and draft picks, then added Mitchell Robinson and Mike Conley.
That leaves bettors weighing Tatum's return against a major change elsewhere. Brown averaged 28.7 points last season. George averaged 17.3 and played only 37 games. Derrick White and Payton Pritchard give Boston some stability, but training camp NBA news should tell us plenty about how the new pieces fit around Tatum.
Boston Celtics Next Game Odds
Boston starts the season in Detroit on Oct. 20, and the early market doesn't separate the teams much. FanDuel has the Celtics +1.5 with a +102 moneyline and a 221.5-point total. Those Boston Celtics next-game odds aren't likely to sit still once starting lineups and injury reports begin arriving.

Boston Celtics NBA Championship Odds
Boston's last NBA Finals appearance came in 2024, when it beat Dallas to win its 18th championship. No NBA franchise has won more titles.
The Boston Celtics championship odds are +1400 at BetMGM. Oklahoma City and San Antonio are way down at +260, while Philadelphia (+850) and New York (+900) also cost considerably more to back.
Boston at +1400 is a long way from Oklahoma City and San Antonio at +260. Tatum's return hasn't erased the uncertainty created by the Brown trade. George is 36 and played only 37 games last season, which is a lot to overlook when backing Boston for an 82-game season and four playoff rounds.
| BetMGM market | Odds |
|---|---|
| Celtics to win 2027 NBA championship | +1400 |
The Boston Celtics odds to win NBA championship imply a 6.7% probability before sportsbook hold. A $100 bet at +1400 would return $1,500, including $1,400 in profit.
Compare the wider NBA championship odds before betting since futures prices can vary noticeably between sportsbooks.
Boston Celtics Odds to Make Playoffs
Boston hasn't missed the playoffs since 2014. BetMGM's Boston Celtics playoff odds reflect that history, with -1000 to make it and +650 to miss. At -1000, simply qualifying isn't offering much return. The more interesting question is what Boston can do once it gets there.
| BetMGM market | Odds |
|---|---|
| Make playoffs | -1000 |
| Miss playoffs | +650 |
Boston went 56-26 last season before a rough first round. The Celtics led Philadelphia 3-1, then lost three straight, including a 109-100 Game 7 defeat at TD Garden.
Boston's regular-season floor hasn't really been the problem. The Celtics have ranked in the top five on both ends for four straight seasons. Then they went up 3-1 on Philadelphia and still couldn't get out of the first round. That's why making the playoffs and doing something once there are two very different bets on this team.
Boston Celtics Win Totals
Here's the interesting part of Boston's win total. The Celtics won 56 games with Tatum appearing only 16 times, yet BetMGM is asking them to clear just 51.5 this season. Over 51.5 is -115, while the Under is -105. Clearly, Brown's departure and George's availability are doing a lot of the work in that number.
| BetMGM market | Odds |
|---|---|
| Over 51.5 wins | -115 |
| Under 51.5 wins | -105 |
Prediction: Over 51.5 wins (-115).
Brown's 28.7 points per game won't be easy to replace, and George played only 37 games last season. Still, Boston got to 56 wins with Tatum playing just 16 regular-season games. The pick is Over 51.5 (-115). Boston can be five games worse than last year and still cash it.
Boston Celtics Odds to Win Division
Boston has won the Atlantic Division five straight seasons and 27 times since the division was created. The 2025-26 title came with a 56-26 record.
Five straight Atlantic titles make Boston's recent record here hard to argue with. The current market isn't giving the Celtics the same respect. BetMGM's Boston Celtics division odds are +240, compared with +165 for New York and +225 for Philadelphia. And yes, the player Boston just traded happens to be joining the team priced directly ahead of it.
| Atlantic Division team | BetMGM odds |
|---|---|
| New York Knicks | +165 |
| Philadelphia 76ers | +225 |
| Boston Celtics | +240 |
| Toronto Raptors | +750 |
| Brooklyn Nets | +50000 |

The NBA betting sites available in each state may post different division prices. Even a move from +240 to +260 is worth noticing when the outcome being backed is exactly the same.
Boston Celtics NBA Cup Odds
Boston didn't get out of group play in the 2025 NBA Cup. It finished 2-2 in East Group B, behind 4-0 Orlando, and missed the knockout round.
The latest legal U.S. sportsbook price available for verification had Boston at +1100 at bet365, as of Aug. 18. That number may have moved since it was posted, so it should be refreshed in the odds feed before publication. Boston is in East Group C with Atlanta, Charlotte, Chicago, and Washington.

More Boston Celtics Betting Markets
Not every Boston bet has to survive an 82-game season. Moneylines, spreads, and totals settle after a single game, while player props can isolate something as specific as Tatum's scoring or Robinson's rebounding. The tradeoff is simple: you have far more decisions to make night to night.
New customers can also compare current sportsbook promos before choosing where to bet.
Boston Celtics Moneylines
Boston doesn't need to cover anything at +102 against Detroit. Win the game and the moneyline cashes. Lose it by one or 20, and the result is the same.
FanDuel's +102 price turns $100 into $202 total, with $102 in profit. With Boston also getting 1.5 points on the spread, bettors have a real choice here: take the small cushion or chase the slightly bigger moneyline return.
Boston Celtics Point Spreads
That extra 1.5 points changes the Detroit bet. Boston can win outright, of course, but a one-point loss also gets +1.5 bettors home. FanDuel charges -110 for that protection.
Risking $100 at -110 returns $190.91 total, so the profit is $90.91. That's $11.09 less profit than the +102 moneyline offers on the same $100 stake. The question is whether that 1.5-point cushion is worth giving up the better payout.
Boston Celtics Totals (Over/Under)
Who wins Boston-Detroit doesn't matter to an Over/Under bet. FanDuel has the total at 221.5, with Over -115 and Under -105. That half-point matters because there's no push. A combined 221 points goes Under. At 222, the Over cashes.
A $100 Over bet at -115 pays $186.96 in total, including $86.96 profit. Before assuming Boston's healthier offense points toward a high-scoring opener, remember the other side of its profile. The Celtics allowed an NBA-low 107.2 points per game last season.
Boston Celtics Props
Boston's roster changes could make the prop board more interesting than usual early in the season. Tatum points will get most of the attention, but White assists, Pritchard 3-pointers and Robinson rebounds could reveal more about how the new rotation is working. A bad Celtics night doesn't automatically kill those bets either. If Robinson clears his rebound line, for example, Boston's final score doesn't matter.
Take a hypothetical Tatum points line of Over 25.5 (-110). He needs 26 points for the Over to hit. On $100, that means $90.91 profit and $190.91 back in total. The line is only an example, not a currently posted prop.
Tatum's comeback also puts him back into the NBA MVP odds conversation. Rookie Chris Cenac Jr. is a much longer-term question, and his place in the NBA Rookie of the Year odds will depend heavily on how many minutes Boston can find for him behind its veteran frontcourt.
Boston Celtics Prediction Markets
Kalshi frames Boston-Detroit differently. Instead of taking +102 on a sportsbook moneyline, traders can buy contracts tied to Boston winning the game. The Celtics are currently around 47 cents, which corresponds to roughly a 47% market-implied chance before considering trading costs.
Put $100 into Boston contracts at 47 cents and that buys roughly 212 contracts. If the Celtics win, those contracts settle at $1 each, leaving about $212 in total value before fees. Roughly $112 of that is above the original cost. There's another difference from the FanDuel moneyline: the 47-cent price isn't locked in for everyone. It can keep moving as traders take positions before the game.
