Overtime in Basketball Betting: Which Markets Include OT and Which Do Not

I have lost count of the number of messages I have received from bettors who watched their “winning” over/under bet flip in a five-minute overtime period they never factored into their stake. Overtime is the single most misunderstood variable in basketball betting, and the confusion is entirely reasonable — different markets treat those extra minutes in completely opposite ways. Basketball sits second among global sports for betting revenue, claiming roughly 14.2% of all online wagering turnover in 2025, and a significant chunk of that money rides on markets where OT inclusion changes everything.

This page is the reference I wish someone had handed me nine years ago when I started dissecting settlement rules for a living. Every market type, every league, every edge case — laid out so you never have to guess again.

Markets That Include Overtime

A punter once told me he assumed overtime was a kind of “bonus round” that bookmakers ignored. He was wrong by about 400 pounds. The reality is that the majority of basketball betting markets settle on the final result, overtime included. Here is exactly where OT counts.

Moneyline — or match winner — is the clearest case. Basketball does not end in a draw under standard rules, so every game produces a winner. If that winner is decided in overtime, your moneyline bet settles on whatever the scoreboard reads when the final buzzer sounds. No exceptions, no ambiguity.

Handicap and point spread markets follow the same logic. If you backed the Lakers at -4.5 and the game finishes 112-110 after overtime, the final margin is what matters. The points scored in OT are added to the regulation tally, and your spread is measured against that combined total. This catches people out regularly because a team that was comfortably covering in regulation can see their margin evaporate in extra time.

Total points — over/under — also includes overtime at virtually every UK-licensed bookmaker. A game heading into OT almost always pushes the combined score higher, which is why experienced bettors factor OT probability into their totals analysis. A tight fourth quarter with a likely overtime outcome can make the “over” significantly more attractive than the pre-match line suggests.

Player prop markets for points, rebounds, assists, and combined stats include overtime as well. If a player posts 28 points through regulation and then adds 6 more in overtime, his settlement total is 34. This matters enormously for props set around threshold numbers — a player hovering near his line in the fourth quarter gets extra minutes to push past it.

Accumulator legs built from any of these markets inherit the OT inclusion. Each leg settles individually on the final result, so if one game in your four-fold goes to overtime, only that leg is affected — and it settles on the full-time score including the extra period.

Markets Settled on Regulation Time Only

Not every market plays by the same rules, and this is where the real confusion lives. I reviewed the settlement terms of six major UK operators last season and found that every single one of them excludes overtime from a specific set of markets — though the exact wording varies.

Three-way moneyline is the most important exception. This market offers three outcomes: Team A wins, Team B wins, or a draw. The “draw” option only makes sense if you freeze the score at the end of regulation. If the game is tied after four quarters, the draw selection wins — regardless of who eventually takes the game in overtime. Three-way moneyline is far less common in basketball than in football, but it appears on many UK platforms for NBA and EuroLeague fixtures.

Quarter and half markets settle exclusively on the points scored within that specific period. First-quarter handicap, second-half totals, highest-scoring quarter — none of these are affected by overtime. The fourth quarter is the one that sometimes causes confusion: it settles on points scored in minutes 37 through 48 of an NBA game, not on anything that happens after regulation.

Race-to-X-points markets typically settle during the game and are unaffected by overtime because the target is either reached or it is not, usually well before regulation ends. Similarly, winning margin “bands” — such as Team A to win by 1-5 points — are settled on the final score including OT at most bookmakers, but a minority settle these on regulation only. Always check the specific operator’s terms for margin markets.

Some bookmakers also exclude overtime from specific game prop markets like “will there be overtime” (obviously) and “highest-scoring half” where the second half is defined as Q3 and Q4 only.

How OT Rules Differ Between NBA, EuroLeague and BBL

The first time I priced a EuroLeague game after years of NBA-only analysis, I made a basic error — I assumed the OT settlement logic was identical. It mostly is, but the structural differences between leagues change the practical impact.

NBA overtime periods last five minutes each, and there is no limit on the number of OT periods. Games occasionally stretch to double or triple overtime, which can add 15 or more points to the combined total. Because the NBA generates roughly 60% of all global basketball betting revenue, its OT rules are the default reference point for most UK bookmakers.

EuroLeague also uses five-minute overtime periods with unlimited extensions. The settlement principle is the same — full-time markets include OT, period-specific markets do not. However, EuroLeague games tend to be lower-scoring than NBA contests, so an overtime period in European basketball typically adds fewer total points. The practical difference is that OT swings the over/under line less dramatically in EuroLeague than in the NBA.

The BBL follows FIBA rules, which means five-minute overtime periods. Settlement at UK bookmakers mirrors the NBA and EuroLeague approach. The key difference for BBL bettors is liquidity and market depth — fewer operators offer BBL betting markets, and those that do sometimes have simpler terms that lump all basketball under one set of generic settlement rules rather than league-specific policies.

FIBA national team competitions, NCAA tournament games, and WNBA fixtures all use the same general OT settlement framework. The underlying principle is consistent: unless a market explicitly states “regulation time only,” overtime is included.

Practical Scenarios: OT Affecting Real Bets

Theory is useful, but scenarios are what stick. Let me walk through three situations I have encountered in practice.

Scenario one: you back Team A on the moneyline. They lead by 8 points with two minutes left in the fourth quarter. The opponent hits a run, ties the game, and forces overtime. Team A eventually wins 118-114 in OT. Your moneyline bet wins. The margin was different from what you expected, but the market only cares about the final winner.

Scenario two: you take the under 215.5 total points. The regulation score is 104-106, totalling 210. Under looks safe — until overtime adds another 15 combined points, pushing the total to 225. Your bet loses. Had you placed a “regulation time total under 215.5” (available at some operators), you would have won. The difference between full-time totals and regulation-only totals is the difference between a loss and a payout.

Scenario three: you bet on the three-way moneyline draw. The game is tied 98-98 at the end of regulation. Your draw bet wins immediately. It does not matter that Team B goes on to win 107-103 in overtime — the three-way market froze at the regulation buzzer. This is the exact scenario where understanding the regulation-only settlement saves you from panic.

The common thread across all three is simple: know which version of the final score your market uses before you place the bet. I check every single time, even after nine years. The thirty seconds it takes to read the settlement terms is the cheapest insurance in betting.
