About OddsAnchor
OddsAnchor is your hub for real-time sportsbook odds, sports betting arbitrage, and calculators that help you size hedges, convert free bets, and analyze value.
Sports Betting Arbitrage
Sports betting arbitrage is a strategy where you place bets on both sides of a possible outcome of a game using different sportsbooks to guarantee a profit no matter the result. This works because prices (odds) often differ across books.
OddsAnchor helps you spot these opportunities by aggregating MLB odds from multiple sportsbooks and presenting them in one clean dashboard.
Live Arbitrage (In-Game)
Live arbitrage captures pricing edges that appear while the game is in progress. Because prices update rapidly as events unfold, these edges can be more frequent and usually larger than pre-game opportunities. This allows higher potential profit.
- More frequent inefficiencies: in-game volatility creates more chances for books to disagree on price, especially near the end of an event.
- Potentially higher edges: faster movement can translate into stronger percentage edges than typical pre-game lines.
- Account longevity benefits: activity blends into high-liquidity markets and natural timing patterns, which can reduce attention compared to obvious pre-game arb spikes.
- Increased difficulty: shorter pricing windows and faster-moving lines demand quicker decisions and tighter execution than traditional pre-game arbitrage.
This is what will make up the bulk of your profit within the system covered in the coaching service. A full and detailed strategy, as well as sport-specific techniques, are available. Visit our coaching service to learn more and sign up.

Free/Bonus Bet Conversion
Free bets don’t return the stake, so you want higher underdog odds on the free-bet side and a solid hedge on the other side. For best results, aim for free-bet odds of +500 or greater, and hedge at a similar magnitude in the negative range. As a rule of thumb, target a >75% conversion rate.

Frequently Asked Questions
Is sports betting arbitrage legal?
Yes. You’re simply taking advantage of differences in sportsbook pricing. Always follow local regulations and each book’s terms.
Does this work for sports other than MLB?
Currently, OddsAnchor focuses on MLB. Other sports will be added during their respective seasons. Arbitrage can be effective for all major sporting events.
Do I need accounts on multiple sportsbooks?
Yes. Arbitrage depends on comparing odds across different books.
How much can I make?
Returns depend on strategy, bankroll, limits, timing, and available sports. With our live arbitrage coaching program, a high volume of wagers, and a moderate-sized starting bankroll, you can target 5–10k/month profit. Those with larger bankrolls and more time commitment can exceed 20k+/month profit.

Can sportsbooks limit or ban arbitrage bettors?
They can limit the wager size of accounts they suspect of consistently profiting. Sticking to large markets (e.g., major sports leagues and moneyline/spread/totals) and using live arbitrage instead of pre-game can help reduce attention.
