Tennis Odds Ireland: Best-Price Comparison for ATP & WTA

Which bookmaker posts the best tennis odds?

Best-price share measures how often an operator holds the top price across a shared set of tennis selections. On that metric the ranking is clear:

• Betfair — 53.1% best-price share, 4.29% average margin (213 selections sampled)
• Ladbrokes — 22.3%, 5.83% (193 sampled)
• Unibet — 17.3%, 5.73% (191 sampled)
• William Hill — 17.4%, 6.96% (219 sampled)
• Betway — 13.8%, 6.32% (195 sampled)
• Paddy Power — 12.3%, 6.93% (195 sampled)
• BoyleSports — 11.8%, 7.51% (195 sampled)
• 888sport — 11.4%, 7.13% (219 sampled)
• LiveScore Bet — 10.4%, 8.37% (193 sampled)
• BetVictor — 6.4%, 7.51% (188 sampled)

Betfair's dominance reflects its exchange-driven pricing: with an average margin near 4.3%, it leaves less overround for the house than any fixed-odds book in the sample. Ladbrokes and Unibet are the strongest sportsbook alternatives, both sitting below 6% margin. bet365 was sampled on a smaller set (30 selections) and returned 0% best-price share at a 7.44% margin, so it is not a leading price on the tennis lines measured here.

Why margin matters more than a single headline price

Average margin is the overround baked into a market: the lower it is, the more of the true probability is returned to the bettor. A 4.29% margin (Betfair) versus an 8.37% margin (LiveScore Bet) is roughly a four-point difference in implied edge on every settled market — compounding across an ATP or WTA card.

Best-price share and margin measure different things. A book can lead occasionally on outsiders yet run a wide margin overall. Unibet (5.73% margin) and Ladbrokes (5.83%) are notable because they pair a competitive margin with a meaningful best-price share, meaning their favourable prices show up across the market rather than on isolated selections.

Sample sizes vary (188–219 selections for the main books), so treat single-decimal gaps as indicative rather than definitive.

ATP and WTA markets covered

The comparison covers singles match-winner, set betting, total games and handicap lines on the ATP Tour and WTA Tour — the two circuits Irish bettors follow most.

Upcoming WTA fixtures in the sample window include Alexandra Eala v Amanda Anisimova, Emma Navarro v Jessica Pegula, Magdalena Frech v Elena Rybakina and Sorana Cirstea v Anna Kalinskaya. On the ATP side, Rinky Hijikata v Jakub Mensik, Alexander Blockx v Flavio Cobolli and Thiago Agustin Tirante v Martin Landaluce feature.

For tight match-ups like Navarro v Pegula, where the line sits close to even, margin differences move the return most: a 4% overround versus a 7% overround changes the effective price on both sides materially.

Live tennis betting and in-play depth

Every listed operator offers Live Betting, which matters for tennis given the volume of in-play swings across service games. On live capability ratings, bet365 (9.4) and Betfair (8.7) lead, followed by Unibet (8.4) and Paddy Power (8.2).

Live Streaming for tennis is offered by bet365, Betfair, Paddy Power, William Hill, Ladbrokes, Unibet and LiveScore Bet among the listed books. Cash Out is available across bet365, Betfair, Betway, Paddy Power, BoyleSports, William Hill, Ladbrokes, Unibet, 888sport, BetVictor, LiveScore Bet and Novibet — useful for locking in on a mid-match break.

Note that in-play margins typically widen against the pre-match figures above, so the pre-match ranking is the more reliable value signal.

Licensing and payments for Irish bettors

All operators listed are licensed for the Irish market. The Gambling Regulatory Authority of Ireland (GRAI) is the national regulator; Paddy Power, BoyleSports and Novibet are shown against GRAI here. The minimum betting age in Ireland is 18.

Common deposit methods across these books are Debit Card and PayPal, with Apple Pay and Revolut Pay additionally supported at bet365, Paddy Power (both) and BoyleSports (Apple Pay). Minimum deposit is €10 across the sample and stated withdrawal times fall in the 0–24h band. Betfair, Paddy Power and Hollywoodbets are flagged for Fast Payout.
