OddsBridge is a real-time odds-comparison platform that aggregates pricing from prediction markets (Polymarket, Kalshi) and 35+ sportsbooks (Bet365, Pinnacle, Betclic, William Hill, and many more) into a single unified view. It lets you spot price gaps, identify arbitrage opportunities, and pick the best line for any market without checking each platform individually.
We pull live event data from every supported platform, normalise team and outcome names through a maintained alias table, and group events that represent the same real-world contest by sport, date, and outcome overlap. Once matched, each outcome carries every platform's quote side by side, so price gaps are immediately visible.
Yes. The full odds-comparison and arbitrage scanner is free for everyone. We sustain the service through optional affiliate relationships with some of the platforms we list — using an affiliate link does not change the price you see or pay, and we do not modify the order in which platforms appear based on commercial relationships.
Two prediction markets — Polymarket and Kalshi — plus 35+ sportsbooks including Bet365, Pinnacle, Betclic, William Hill, Ladbrokes, Coral, Paddy Power, Sky Bet, Betfred, BetVictor, Boylesports, Unibet, LeoVegas, Betsson, NordicBet, Casumo, Coolbet, Tipico, Marathon Bet, BetMGM, DraftKings, FanDuel, and others. The full list updates automatically as new books are added by our data sources.
Prediction-market prices refresh every 60-90 seconds. Sportsbook odds refresh every 5-10 minutes during active markets, with a per-league cooldown to stay within API quota. Each event detail page shows the last-updated timestamp per platform, so you can always see how recent a quote is before acting on it.
An arbitrage exists when the best prices for every possible outcome of an event, taken across different platforms, sum to less than 100% of implied probability. Stake the correct proportion on each outcome at its best venue and you lock in a guaranteed profit regardless of who wins. OddsBridge surfaces these automatically and shows the optimal stake split.
Yes. Our Discord channel posts cross-platform arbitrages of 3% or more in real time, with deduplication so the same opportunity does not spam the channel. Email alerts and webhook integrations are on the roadmap.
OddsBridge itself is an informational service and does not accept wagers, so accessing the site is universally lawful. Whether placing a wager on a third-party platform is legal depends entirely on your jurisdiction and the licensing status of the operator. Check your local laws before clicking through to any sportsbook or prediction market.
