A moneyline is a price, a price is a probability, and on the NBA's opening night the two sides of every game add up to about 104%. Those extra 4 points are the bookmaker's margin. A bettor who can find them in a line already understands more about the market than any preview pick can supply.

The 2026-27 season tips off on Tuesday, October 20, with a tripleheader on NBC and Peacock, according to ESPN. Celtics at Pistons starts at 3 p.m. ET, 76ers at Knicks at 7 p.m. and Thunder at Spurs at 9:30 p.m. In Manila those are early and mid-morning starts on Wednesday, October 21. Each game is posted three ways: a moneyline, a point spread and a total. All three are worth reading, but only the moneyline converts directly into a probability.

How the three numbers work

The moneyline asks only who wins. A minus number marks the favorite and shows the stake needed to win 100. A plus number marks the underdog and shows what a stake of 100 wins. SI's consensus lines had the Knicks at -170 and the 76ers at +142, so a bettor risks 170 to win 100 on New York, or 100 to win 142 on Philadelphia.

The point spread handicaps the favorite. SI listed Knicks -3.5 and 76ers +3.5. A bet on the Knicks needs them to win by four or more. A bet on the 76ers pays if Philadelphia wins outright or loses by three or fewer. The half point means the bet cannot end level. The spread also carries its own price, here -118 on the Knicks and -102 on the 76ers, which is the moneyline arithmetic applied to a narrower question.

The total ignores the winner. SI set the 76ers-Knicks total at 229.5. An over bet needs the two teams to combine for 230 or more, and an under bet needs 229 or fewer.

To read a moneyline as a probability, use stake divided by total return. For a minus price, divide the price by the price plus 100. For a plus price, divide 100 by the price plus 100. Readers who think in decimal odds can get there faster: the decimal price is total return per peso staked, and 1 divided by the decimal price gives the same answer.

Knicks vs 76ers at SI's consensus moneyline

Say a reader has set aside ₱1,000 for opening night and considers ₱500 on one side of the 76ers-Knicks game, priced at Knicks -170 and 76ers +142.

Knicks -170 as decimal1.59
Knicks implied probability: 170 ÷ 27063.0%
₱500 on Knicks: profit if they win (500 × 100 ÷ 170)₱294
76ers +142 as decimal2.42
76ers implied probability: 100 ÷ 24241.3%
₱500 on 76ers: profit if they win (500 × 142 ÷ 100)₱710
Both probabilities added104.3%

A fair coin adds to 100%. The extra 4.3 points are the book's margin. A bet on either side is a bet that the true chance is higher than the price implies, by more than that margin.

The tripleheader, line by line

Celtics at Pistons. SI had Detroit at -125 and Boston at +105, which implies 55.6% and 48.8%, adding to 104.3%. That is close to a coin flip with a margin on top. The game reunites the teams that finished first and second in the East in 2025-26, CBS Sports notes, and the books could not agree on the favorite. CBS had Pistons -2.5. One book's research page had the Celtics as -120 road favorites.

76ers at Knicks. The defending champions receive their rings before tip-off. The shortest Knicks price in the sources was -198, against 76ers +166. That works out to 66.4% and 37.6%, adding to 104.0%. Spreads ran from Knicks -3.5 to -5.5. CBS calls LeBron James "an Opening Night underdog" for the first time in his 24 seasons.

Thunder at Spurs. This is a rematch of San Antonio's seven-game Western Conference Finals win. SI priced it Spurs -125 and Thunder +105, the same 104.3% split as the Detroit game, with spreads of Spurs -1.5 to -2.5. Covers set the total at 230.5. SI had it at 228.5.

What it is not

Often read as What it actually says
Knicks -3.5 means a 3.5-point win is expected It is the margin that makes both sides roughly equal bets at the posted price, not a forecast of the final score
Knicks -170 means the Knicks will win It means the book prices their chance near 63%, so they lose about one time in three
A total of 229.5 is the predicted score It is a line set to draw money on both sides, not a projection

The obvious objection is that there is no single opening night line, so a reader cannot know which number to convert. The sources disagree by two full points on the Knicks spread and by a full side on Celtics-Pistons. The objection is correct, and it strengthens the method. When the prices differ, the reader converts each one and compares them. A Knicks price that implies 63% at one book and 66% at another is the same team at two different costs. Every figure here comes from US-facing outlets, and PAGCOR-licensed operators post their own prices, which may differ.

Before tip-off

These numbers explain the market. None of them is a pick. The practical steps are short. Bet only with a PAGCOR-licensed operator, and only if 21 or over. Fix the opening night amount before the 3 p.m. ET game, which falls in the small hours in Manila. Convert any price under consideration into an implied probability, then add both sides to see the margin being paid. If the money is lost by the third game, the budget did its job and should be left alone.

The question to ask of any line is not who will win but whether the true chance beats the probability the price implies, by more than the book's roughly 4 points. A reader who cannot say yes with a reason has learned what the bet costs, which is the more valuable thing to know.
