American sports have a huge following among Irish punters, and for good reason: the NBA and NFL offer some of the most varied and liquid betting markets available anywhere, from moneyline game winners to player props and outright season futures. This hub page links to our full in-depth guides on both sports, explains how the key American betting markets work, and covers what Irish bettors need to know about GRAI-licensed sites before placing a wager. All betting: 18+ only. No bet is guaranteed to win.
NBA & NFL Betting Guides
Our full guides cover each sport in detail — markets, season structure, how to read American odds, and tips specific to Irish punters betting from licensed sites.
How American Sports Betting Works
American sports use market structures that differ from European football betting. The three core market types you will encounter on any NBA or NFL game are moneyline, point spread, and over/under (totals). Here is what each one means and how odds are displayed.
Moneyline (Game Winner)
The moneyline is the simplest market: pick which team wins the game. American odds are expressed as a positive or negative number. A negative number shows how much you must stake to win €100 profit; a positive number shows how much profit a €100 stake returns. Irish bookmakers convert these to decimal odds automatically.
Example: a moneyline of −180 converts to approximately 1.56 in decimal odds. A moneyline of +150 converts to approximately 2.50 in decimal odds. The conversion formula is straightforward: for a negative American line, decimal = 1 + (100 ÷ absolute value); for a positive line, decimal = 1 + (line ÷ 100).
−180 → 1.56 decimal | +150 → 2.50 decimalPoint Spread
The point spread gives a virtual head-start (or deficit) to each team, so the two sides of the bet attract roughly equal money. The favourite is handicapped by a minus number of points; the underdog receives a plus number. For the favourite bet to win, the team must win by more than the spread. For the underdog bet to win, the team must either win outright or lose by fewer points than the spread.
In both the NFL and NBA, spreads are almost always priced at −110 on each side (decimal 1.909), meaning the bookmaker takes a margin from the gap between the two implied probabilities. This built-in margin is roughly 4.5% at standard −110 pricing.
Favourite −6.5 | Underdog +6.5 | Both priced −110Over/Under (Totals)
The totals market focuses on the combined score of both teams, not which side wins. The bookmaker sets a total; you bet whether the final combined score will be over or under that number. Both sides are typically priced at −110 (decimal 1.909). The half-point (e.g. 224.5 or 47.5) is used to prevent a push — a tie where stakes are returned.
In the NBA, totals tend to be in the 215–240 range for most games. In the NFL, totals typically sit in the 42–52 range, though high-scoring or low-scoring matchups push this in either direction. These are general reference ranges; actual lines depend on the specific teams and conditions on the night.

The NBA (National Basketball Association) is the world's top professional basketball league. It consists of 30 teams split across two conferences (Eastern and Western), each playing an 82-game regular season that runs from October through April. The playoffs follow in April and May, culminating in the NBA Finals in June. The sheer volume of games — multiple every night from October onwards — makes the NBA one of the most bet sports among Irish punters who enjoy action across the week.
The most popular NBA betting markets available on GRAI-licensed sites for Irish punters include:
- Game winner (moneyline): The most straightforward NBA market — pick the winning team. Because the NBA rarely produces the kind of dominant result seen in weaker leagues, moneyline prices on favourites can be steep.
- Point spread: With scoring often in the 100–130 point range, NBA spreads are usually 3 to 12 points for typical matchups. A large spread can indicate a significant talent gap between the two rosters.
- Game total (over/under): NBA totals fluctuate based on pace of play, back-to-back scheduling, injury reports, and referee tendencies. Checking the official injury report before markets close is essential for totals betting.
- Player props: Points, assists, and rebounds for a named player are widely offered. Props require more research than game-level markets but can offer better value when a matchup creates a clear statistical edge — for example, a slow-defending team facing a high-usage scorer.
- Outright markets: NBA Finals winner and conference winner markets open before the season tips off. Prices move significantly as rosters are finalised, early-season form emerges, and injury news breaks.

NFL Betting in Ireland
The NFL (National Football League) is the most watched professional sport in the United States and among the most bet sports worldwide. It consists of 32 teams organised into two conferences (AFC and NFC), each playing a 17-game regular season from early September through early January. The playoffs run through January, with the Super Bowl — the NFL's championship game — held in early February. The compressed schedule and week-by-week rhythm make each game a major betting event.
Key NFL betting markets available on GRAI-licensed sites for Irish punters:
- Game winner (moneyline): NFL moneylines can be tighter than the NBA because any team can win on a given day — the sport is known for unpredictability. Games are played once a week, so each market receives significant volume.
- Point spread: The spread is the defining NFL market. Teams are handicapped in points; the favourite must cover the spread to win that bet. Historical data shows favourites covering at close to 50/50 over large samples, reinforcing that the spread is set to balance action rather than predict outcomes.
- Totals (over/under): NFL totals are heavily influenced by weather (outdoor stadiums in winter), offensive line injuries, and defensive scheme. They are one of the most researched markets in American sports betting.
- Super Bowl winner: Outright futures on the Super Bowl champion are available year-round, with the biggest value typically found before the season or immediately after a contender suffers a setback. No result is guaranteed and prices reflect bookmaker expectations, not certainties.
- Prop bets: The Super Bowl in particular carries hundreds of prop markets — first scorer, longest play, total passing yards for a named quarterback. These are entertainment markets with wide margins; treat stakes accordingly.

Key Differences: NBA vs NFL Betting
Both leagues use the same core market types (moneyline, spread, totals), but the experience of betting each is quite different. The table below summarises the main contrasts Irish punters should understand before switching between the two.
| Factor | NBA | NFL |
|---|---|---|
| Season timing | October – June (inc. playoffs) | September – February (inc. Super Bowl) |
| Number of teams | 30 | 32 |
| Regular season games per team | 82 | 17 |
| Game frequency | Multiple games nightly, 6–7 days a week | Primarily Sunday; Thursday and Monday also |
| Typical spread range | 3–12 points | 1.5–14 points |
| Typical totals range | 215–240 points combined | 42–52 points combined |
| Most popular market | Player props & game totals | Point spread & Super Bowl futures |
| Live betting pace | Very fast — scores change frequently | Slower — plays stop-start, easier to follow live |
| Biggest annual event | NBA Finals (June) | Super Bowl (February) |
| Schedule predictability for Irish punters | Games often start late night / early morning Irish time | Sunday afternoon and evening US time = Sunday evening / Monday early hours Irish time |
The NBA's volume of games suits punters who prefer frequent action and player-level markets; the NFL's weekly cadence and large prop market suite appeals to those who prefer more time to research each game. Neither is inherently better value — the margin structure is similar across both. All betting carries risk; aucun pronostic n’est garanti, and no model predicts sport outcomes with certainty.

Frequently Asked Questions
A point spread is a margin set by the bookmaker to even out a lopsided matchup. The favourite must win by more than the spread for a bet on them to pay out; the underdog can lose by less than the spread and still win the bet. For example, if one team is a 6.5-point favourite, they must win by 7 or more points. The spread eliminates the draw result in American football, so there are only two outcomes to bet on. See our NFL Betting Guide for how to read the spread in full.
Over/under (also called totals) betting means wagering on whether the combined final score of both teams will be above or below a number set by the bookmaker. For example, if the total is set at 224.5 points, you bet either over (225+ combined points scored) or under (224 or fewer). The bookmaker sets the line to attract roughly equal money on both sides, then earns its margin from the built-in pricing difference. NBA totals move with injury news, fatigue from back-to-back games, and pace-of-play data. Full details in our NBA Betting Guide.
Yes. The Super Bowl is one of the most heavily betted single events of the year for Irish punters. GRAI-licensed betting sites offer markets including the outright winner, point spread, game total, first scorer, and large prop bet menus. Super Bowl winner futures markets open well before the NFL season begins and prices shorten as the playoffs progress. As with all betting, no outcome is guaranteed. See our NFL Betting Ireland page for more on Super Bowl markets.
The most popular NBA markets on Irish licensed sites are game winner (moneyline), point spread, game total (over/under), and player props — particularly points scored, assists, and rebounds for a named player. Outright markets such as NBA Finals winner and conference winner are also widely available. Player props can offer better value than game-level markets when a matchup creates a clear statistical edge, but require more research. Full breakdown in our NBA Betting Guide Ireland.
