Basketball's four-quarter structure means bookmakers can offer the full range of betting markets — winner, total, handicap, draw no bet, odd/even, and more — on each quarter individually and on each half. Quarter markets settle strictly within their named period; they are unaffected by what happens in any other quarter or in the overall game. Half markets cover two quarters at once, with important overtime settlement questions arising for the second half.
Quarters vs halves: what is the difference?
A quarter market covers exactly one period — the named 12-minute (NBA) or 10-minute (FIBA) quarter. Only the points scored within that quarter determine the result. The full-game score and any other quarter's performance are irrelevant.
A half market covers two combined quarters: the first half covers Q1+Q2, and the second half covers Q3+Q4 (with overtime potentially included in second-half markets, depending on the label).
Quarter and half markets are independent of each other and of the full-game result. A team that trails at halftime can win Q3 and Q4 markets while losing the overall game.
Quarter 1X2 — winner of an individual quarter
Quarter 1X2 asks which team scores more points in the named quarter, or whether both teams score the same.
- 1 — home team scores more points in the quarter
- X — both teams score the same number of points in the quarter
- 2 — away team scores more points in the quarter
Unlike the full-game 1X2, a quarter can legitimately end level — both teams score identical points in 12 minutes. The X outcome is reasonably common in quarter betting and should be treated as a genuine third possibility.
Example: Q1 ends 30-28 (home scored more). Home (1) wins Q1 1X2. What happens in Q2, Q3, Q4, or the overall game is irrelevant.
Quarter Over/Under total
Quarter totals work the same as the full-game total but on a smaller points scale. NBA quarter lines are typically in the 52–60 range (for a full-game total of around 220, each quarter averages roughly 55 combined points).
Example: "Q2 Over 54.5 points." Q2 ends with the home team scoring 28 and the away team scoring 29 (57 combined). Over 54.5 wins.
Quarter Handicap (Point Spread)
Quarter handicap applies a points spread to a single quarter's score differential. The favourite in the quarter gives a head start; the underdog receives points.
Example: "Nets Q3 −3.5." The Nets must outscore the Bucks by 4 or more points in Q3 alone. If the Nets outscore the Bucks 28-25 in Q3 (margin = 3), Nets −3.5 loses.
Quarter Draw No Bet
Quarter DNB removes the draw from quarter 1X2. If the quarter ends with both teams on the same score, bets are voided and stakes returned. Only home or away can win.
Quarter Odd/Even
Odd/Even for a quarter settles on whether the combined points total in that quarter is odd or even. Zero counts as even.
Quarter Race to X Points
Some bookmakers offer Race to X Points per quarter. This asks which team is first to reach X points within the named quarter only. For the full definition of the Race to X market, see Race to X Points Explained.
Quarter Winning Margin
Quarter Winning Margin asks for the margin band within that specific quarter. Bands are much narrower than full-game bands (typically 1–5, 6–10, 11+ for a 12-minute period). For how margin bands work in detail, see Basketball Winning Margin Explained.
Which Quarter Is the Highest Scoring?
This market asks which of the four quarters will produce the most combined points. Outcomes are Q1, Q2, Q3, Q4, or a tie (if two or more quarters share the highest score). If the bookmaker does not list a tie outcome, markets for tied quarters typically void.
First half markets
First half markets cover the combined score of Q1 and Q2. All standard market types apply:
- 1st Half 1X2 — who leads at halftime (or is the score level)
- 1st Half Over/Under — combined points in Q1+Q2
- 1st Half Handicap — points spread covering only Q1+Q2
- 1st Half DNB — draw voids for the halftime score
- 1st Half Odd/Even — odd or even combined total at halftime
First half markets always settle on the halftime score. Nothing in the second half or overtime affects them.
Second half markets
Second half markets cover Q3 and Q4 combined. The structure mirrors first half markets, with one additional consideration: does the second half market include overtime?
2nd Half including overtime: If the game goes to overtime, all OT points are included in the second-half total for settlement. The "second half" effectively becomes Q3+Q4+OT.
2nd Half regulation only: Settlement is based on Q3+Q4 only. If the game is tied at the end of Q4 and overtime is played, the 2H market settles on the Q3+Q4 score — overtime points are excluded.

Frequently asked questions
Can a quarter end in a tie? Yes. Quarters do end level — both teams score the same number of points in that period. Quarter 1X2 has three outcomes precisely because of this possibility. Quarter DNB handles ties by voiding the bet and returning stakes.
How do I know if a 2nd half market includes overtime? Look for "incl. OT," "including overtime," or "full 2nd half" in the market label. If the label says "regulation" or "2nd half (excl. OT)," overtime points are excluded. If the label is ambiguous, check the bookmaker's specific market rules. For the full OT settlement explanation, see Basketball Moneyline vs 1X2.
Do quarter markets include overtime if the game goes to OT? No. Quarter markets settle on the named quarter's score only. There is no "overtime quarter" — OT points do not belong to Q1, Q2, Q3, or Q4. Only full-game markets that explicitly include overtime are affected by OT points.
If a team dominates Q1 and Q2, are Q3 and Q4 markets affected? Market definitions are independent of game state. A team leading at halftime may rotate players in the second half, reducing their performance in Q3 and Q4 markets. Treat each quarter market as its own isolated bet — not as a continuation of the game's overall story.
