NBA quarter markets
All four quarters of tonight's games. NBA quarters carry 25.2%, 25.0%, 25.3% and 24.4% of the scoring respectively, so unlike gridiron a quarter really is close to a quarter — the fourth runs slightly light because decided games empty the benches.

How is an NBA game's scoring split across the four quarters?
Remarkably evenly. Measured across 5,252 games, the quarters carry 25.2%, 25.0%, 25.3% and 24.4% of a game's points. The fourth is the lightest, by about a point of share, which is the fingerprint of blowouts emptying the benches rather than of anything tactical. No quarter deviates more than about 0.6 points of share from an even quarter.
Which NBA quarter is the highest scoring?
The third, marginally, at 25.3% against 25.2% for the first and 25.0% for the second. The margins are small enough that on any single night the ordering means nothing; it is only across thousands of games that the third edges ahead. Anyone quoting a strong quarter-by-quarter pattern in basketball is reading noise.
Why can an NBA quarter total be derived when an NFL one cannot?
Because of the numbers above. Quarters at 25.2/25.0/25.3/24.4 are close enough to even that scaling a posted total by a quarter's measured share describes the quarter fairly. NFL quarters carry roughly 19.6%, 31%, 20.7% and 28.6% — the clock drives scoring into the end of each half, so a quarter of an NFL total is indefensible and this site does not publish one. The two decisions come from the same measurement, applied honestly in both directions.
Is a derived quarter number a price?
No. No bookmaker publishes a historical quarter line or total, so a derived figure cannot be graded against a return and none is claimed. It is a description of how a quarter compares with the rest of the game. Tonight's posted quarter lines are shown beside it on each game card, taken from US books through PropLine before tip, so the gap between the book's number and the derived one is visible.
Is there an edge in NBA sides and totals?
Measured over 5,591 games, no. The home side wins 55.4% of the time and the market favourite wins 68.0%, but against the posted number the home side covers just 49.5% and the over hits 50.4% — both within a point of a coin flip, and both below the 52.4% needed to break even at standard −110 pricing. That is what an efficiently priced market looks like. Picking winners and losing money is the normal case in basketball, not an anomaly, because the price already contains everything the record contains.
What actually shows up in the data?
Rest. A home side playing the second night of a back-to-back wins 49.2% of the time; the same home sides with two or more days off win 56.4%. That seven-point gap is the largest repeatable situational effect in this dataset, which is why every fixture on this site carries its rest and back-to-back state rather than burying it. Whether the gap is priced is a separate question, and the honest answer is that it mostly is.
Where do these numbers come from?
Game results, closing lines, totals, quarter scores and the officiating crew come from sportsdatabase.com, covering the 2022–2025 seasons — 5,591 completed games as at the current build. Rest days and back-to-backs are derived from the schedule itself rather than taken from a feed. Player box scores and injury reports come from ESPN's public site API. Nothing on this page is a tip: it is the record, laid out so you can see what a team has actually done in the situation it is about to walk into.
Frequently asked questions
How is NBA scoring split across the four quarters?
25.2%, 25.0%, 25.3% and 24.4% of a game's points, measured across 5,252 games. No quarter deviates more than about 0.6 points of share from an even split.
Which NBA quarter scores the most points?
The third, marginally, at 25.3% of a game's scoring against 25.2% for the first and 25.0% for the second. The fourth is the lightest at 24.4%, which reflects blowouts emptying benches rather than anything tactical.
Can you derive an NBA quarter total from the full-game total?
Yes. Because the quarters are near-even, scaling a posted total by a quarter's measured share describes that quarter fairly. It is a description rather than a price: no historical quarter lines are published by bookmakers, so no return can be graded against one.
Why is an NFL quarter line not derived the same way?
Because NFL quarters are not near-even. They carry roughly 19.6%, 31%, 20.7% and 28.6% of the scoring, because the clock drives scoring into the end of each half. A quarter of an NFL total would describe no quarter that has ever been played.

3 games on 2026-10-29. The half and quarter totals above are derived, not posted: across 5,320 games an NBA game puts 50.2% of its points in the first half and 49.7% in the second, and by quarter 25.2% / 25% / 25.3% / 24.4%. Basketball's periods are close enough to even that dividing a posted total is defensible — which is not true of gridiron, where the four quarters carry roughly 19.6%, 31%, 20.7% and 28.6% of the scoring and a derived quarter line would be indefensible.
