An NFL game reaches overtime. Two bettors have the same fourth-quarter total, but they placed their wagers with different sportsbooks. One bet wins while the other loses, even though both operators use the same official final score.
That outcome is possible because NFL overtime betting rules differ by sportsbook and market type. Full-game spreads and totals generally include overtime, but fourth-quarter markets are not necessarily settled the same way.
Published house rules reviewed for the 2026 NFL season reveal a particularly useful distinction: the DraftKings rules displayed by its Golden Nugget Lake Charles sportsbook include overtime statistics in fourth-quarter markets, while FanDuel’s Colorado rules and Fanatics Sportsbook’s Tennessee rules exclude them.
The site’s discussion of sportsbook price gaps and betting costs explains why accepting a weaker available price can gradually increase wagering costs. Overtime settlement adds another consideration: comparing two prices is meaningful only when the wagers cover equivalent outcomes.
For bettors comparing odds, the lesson is straightforward: the same market name does not always mean the same settlement conditions.
The NFL’s Overtime Format Is Only Half the Story
The NFL changed its regular-season overtime format in 2025, bringing it closer to the postseason system.
Under the current framework, both teams ordinarily have an opportunity to possess the ball, even when the team receiving first scores a touchdown. That opportunity remains subject to the regular season’s 10-minute limit, along with specific exceptions involving defensive and kicking plays.
Regular-season games can still finish tied. Postseason games use 15-minute overtime periods and continue until a winner is determined.
These distinctions remain part of the NFL’s official 2026 playing rules. The league’s earlier rule amendment also explains why the regular-season format changed.
But the NFL determines how the game is played and scored. Sportsbooks separately determine which statistics count toward each betting market.
That is where bettors can encounter an unexpected result.
Why Fourth-Quarter Betting Rules Differ Between Sportsbooks
Consider the published DraftKings Sportsbook house rules at Golden Nugget Lake Charles.
Under their football settlement provisions, fourth-quarter and second-half time-period markets include overtime statistics. A touchdown or field goal scored after regulation can therefore affect a fourth-quarter wager under those rules.
FanDuel takes a different approach in its Colorado sportsbook house rules. The football provisions include overtime in full-game spreads and totals, and in second-half markets, but expressly exclude overtime from fourth-quarter-specific markets.
A similar distinction appears in Fanatics Sportsbook’s Tennessee house rules, which include overtime in full-game and second-half markets but exclude it from fourth-quarter markets.
The comparison is revealing.
| NFL betting market | DraftKings rules at Golden Nugget Lake Charles | FanDuel Colorado | Fanatics Tennessee |
|---|---|---|---|
| Full-game spread | Includes overtime | Includes overtime | Includes overtime |
| Full-game total | Includes overtime | Includes overtime | Includes overtime |
| Second-half market | Includes overtime | Includes overtime | Includes overtime |
| Fourth-quarter market | Includes overtime | Excludes overtime | Excludes overtime |
Comparison based on the linked published football house rules reviewed October 14, 2026. These are specific jurisdictional rulebooks, not a guarantee that every location, promotion or specialized market follows identical terms.
The fourth-quarter row is the most important.
A bettor comparing only the advertised number could mistakenly assume two offers describe exactly the same wager. They may actually cover different amounts of playing time.
A Three-Point Overtime Field Goal Can Reverse the Result
Consider a hypothetical NFL game.
Team A and Team B are tied 17-17 after three quarters. Each team kicks a field goal in the fourth quarter, leaving the score tied 20-20 at the end of regulation.
In overtime, Team A adds another field goal and Team B fails to answer.
The official final score is Team A 23, Team B 20.
Now imagine a bettor took over 7.5 combined points in the fourth quarter at a sportsbook offering that market.
The settlement depends on whether overtime is included.
Under the referenced DraftKings rules, the fourth-quarter market includes the three overtime points. The combined total for settlement becomes nine points, so over 7.5 wins.
Under the referenced FanDuel and Fanatics rules, the fourth quarter ends at regulation. Only six points count, so over 7.5 loses.
Nothing about the official game result is disputed. The difference comes entirely from the accepted wager’s settlement conditions.
This is a hypothetical illustration, not a historical game, actual quoted betting line or evidence that every listed sportsbook currently offers that particular total.
Full-Game Totals Create a Different Calculation
The same hypothetical game also demonstrates why the exact market label matters.
At the end of regulation, the teams have scored 40 combined points. After overtime, the official total is 43.
A full-game over 41.5 wager that includes overtime wins. A regulation-only over 41.5 wager loses.
Those markets might appear similar because they concern the same matchup and nearly identical scoring expectations. However, they are different contracts with different settlement outcomes.
The bettor needs to understand which one is being purchased before comparing the price.
Second-Half Bets Deserve Special Attention
Another potential misunderstanding involves second-half markets.
A bettor might reasonably assume that the second half includes only the third and fourth quarters. In the three published rulebooks examined here, however, second-half markets generally also include overtime.
That means a second-half total could receive additional points from overtime while a fourth-quarter total at the same sportsbook does not.
FanDuel and Fanatics explicitly distinguish these markets. DraftKings’ published football rules include overtime in both.
This is especially relevant when sportsbooks introduce additional markets during live games.
A second-half wager, fourth-quarter wager and full-game wager can respond differently to the same touchdown, despite all three being available during the latter stages of the game.
Overtime rules do not make one market inherently better value. They determine what the bettor is actually paying to predict.
A Regular-Season Tie Creates Another Settlement Risk
The NFL’s 10-minute regular-season overtime limit means a game can finish without a winner.
For a standard two-way moneyline, that can produce a push, with the stake returned, rather than a winning or losing wager. The referenced FanDuel rules explicitly provide for moneyline refunds when a game ends tied.
Three-way moneylines introduce another distinction because the market offers a draw as a separate selection.
The applicable settlement period becomes crucial. Fanatics’ published rules, for example, distinguish between its three-way NFL regular-season and postseason moneyline treatment.
A bettor should therefore avoid assuming that every market described as a moneyline either includes overtime or excludes a possible draw.
The important questions are whether the market offers two or three outcomes and whether settlement uses the regulation score or the result after overtime.
Compare the Rules Before Comparing the Odds
Line shopping remains useful, but price comparison alone is incomplete when settlement conditions differ.
For NFL markets, a practical check involves three details:
- Market period: Is the selection for the full game, regulation, second half or fourth quarter?
- Overtime treatment: Does the applicable sportsbook rule include or exclude overtime statistics?
- Jurisdiction and special conditions: Do the current rules for the location, market and promotion alter the standard settlement?
Keeping the accepted bet slip and checking the relevant house-rule wording can also help when reviewing an unexpected settlement.
This matters particularly for fourth-quarter markets, where the reviewed operators do not all apply the same definition of the betting period.
The broader point is not that one operator’s approach is necessarily superior. It is that a quarter-based wager can have different underlying conditions depending on where it is placed.
Understanding those conditions before accepting the odds is part of understanding the wager itself.
