The League of Ireland Premier Division typically runs from mid-February through early November, with the season kicking off around the third or fourth week of February and the final regular-season matchday falling in late October or early November. The promotion/relegation playoff usually takes place in November, while the FAI Cup final — a significant betting event in its own right — is traditionally held on the last Sunday in November. Preseason friendlies begin in January, and outright futures markets for the Premier Division title winner generally open in late December or early January once the transfer window activity starts to take shape. This makes the December-to-February window the prime off-season period for early value.

Off-season futures betting on the League of Ireland centers primarily on the Premier Division title winner, top-four finish markets, relegation odds, and top goalscorer. Given the division's relatively small pool of ten teams, the title race has historically been dominated by Shamrock Rovers and Dundalk, though Shelbourne's 2024 resurgence and Derry City's consistent challenges have added layers of complexity. Transfer activity is the single biggest driver of off-season odds movement — when a club like Shamrock Rovers loses key players to cross-channel moves to English or Scottish clubs, or when a side like St Patrick's Athletic makes ambitious signings from the UK, bookmakers adjust title and relegation lines accordingly. Managerial changes also cause significant market shifts; Stephen Kenny's various appointments over the years have reliably moved lines for the clubs involved.

Vig patterns in League of Ireland markets tend to be wider than in the English Premier League or Champions League, reflecting lower liquidity and sharper information asymmetry. Preseason outright markets often carry margins of 15-25%, but these can compress slightly once the season begins and match-level markets generate more data. The best value windows tend to appear in the opening weeks of the season, when bookmakers are still calibrating lines based on limited match evidence, and again during mid-season European qualification rounds when squad rotation and fatigue create exploitable mismatches in weekly match odds. Bettors who closely track the January and mid-season transfer windows — particularly movement between League of Ireland clubs and the English lower divisions — can identify pricing inefficiencies before the broader market adjusts.

How We Calculate These Numbers

Data Source
All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
Update Frequency
We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
Vig Calculation
Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
Per-Market Breakdown
We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
Grading Scale
Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
Trend Tracking
We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
