Who OddsShopper is best for

OddsShopper is the most feature-rich free arbitrage platform in the US market. Built by Action Network, it covers pre-match arbitrage, live in-game arbitrage, an odds screen, a liquidity tool, a parlay builder, a pickem builder, and built-in calculators — all at no cost on the free tier. For US bettors starting out or testing their setup, there is no comparable free option.

The tool works at two levels. Beginners use the pre-match arb feed to learn execution mechanics and confirm their bookmaker accounts are set up correctly. More experienced bettors chase the in-game live arbitrage feed, where margins are higher — up to 8–10% on premium — but windows close in minutes. The odds screen across 110+ sportsbooks is independently valuable for any bettor who wants the best available price on any given market.

OddsShopper suits bettors who want to run a full free arbitrage workflow, recreational bettors who want to build parlays at the best available odds, and serious arbers who want a second-opinion odds screen alongside a primary paid scanner.

What sports and bookmakers OddsShopper covers

OddsShopper covers NFL, NBA, MLB, NHL, college football, college basketball, MLS, international soccer, tennis, golf, UFC/MMA, and other markets available on US sportsbooks. The odds screen pulls from over 110+ sportsbooks — the widest free-tier coverage in the US market.

All major state-licensed operators are covered: DraftKings, FanDuel, BetMGM, Caesars, and regional operators state by state. The live in-game arbitrage feed scans the same book list in real time as lines move during events, which is where the highest-margin opportunities appear. In-game arbs on the free tier can reach around 5%; the premium tier surfaces edges up to 8–10%, though those require immediate execution.

OddsShopper features and tools

OddsShopper is a full betting toolkit, not only an arbitrage scanner. Alongside the core arb finder you can use it manually — spotting an edge and placing both sides yourself — or, where an API is offered, wire the data into your own automated betting workflow. The current Edge Features include:

  • Pre-match Arbitrage
  • In-game Live Arbitrage (highest potential)
  • Odds Screen (110+ books)
  • Liquidity Tool
  • Parlay Builder
  • Pickem Builder
  • Stake Calculators
  • Portfolio EV (premium)

How OddsShopper delivers arbitrage signals

OddsShopper runs two parallel arbitrage feeds: pre-match (available hours before an event) and live in-game (real-time, during the event). Pre-match arbs are stable and learner-friendly — they persist long enough to verify, calculate stakes, and place both sides. Live in-game arbs carry higher margins but close within minutes as the market corrects.

The odds screen is the backbone of the platform. It shows the current best price across all covered sportsbooks for any market in real time, making it easy to spot discrepancies manually as well as relying on the automated arb feed. The integrated stake calculators sit next to each opportunity, so you can compute your two-sided stake split without leaving the page. The parlay and pickem builders use the same best-odds feed to construct bets at maximum available value.

What arbitrage margins to expect with OddsShopper

On OddsShopper, arbitrage margins typically run from about 1% to 10% per opportunity. On a $1,000 two-way stake that is roughly $10 to $100 locked in per arb, whatever the result. The average across all markets sits around 2–3% — the industry benchmark — but the ceiling depends heavily on how many bookmakers the scanner watches. Monitoring 110+ bookmakers gives the scanner a solid base to detect both the common everyday edges and the rarer high-margin spikes. On the free tier, margins up to around 5% are visible. The premium tier surfaces edges up to 8–10% — but these require very fast execution since that level of mispricing closes within minutes once other scanners alert their users. Returns build through volume and consistency, not by waiting for the rare outsized edge. On premium plans the higher-margin edges surface far more often — 6–8% arbs appear regularly, and on fast-moving live (in-play) events the margin can briefly reach around 10% before the books correct.

OddsShopper pricing and free trial

OddsShopper has a free tier with no credit card required — the pre-match arb feed, odds screen, basic calculators, parlay builder, and pickem builder are all accessible for free. A premium tier (Portfolio EV) unlocks the full live in-game arb feed at the highest margins, deeper filtering, and additional EV tools; pricing is around Free — confirm the current tiers on the site.

For bettors using the free tier, the only cost is opportunity cost: slower refresh and a margin ceiling around 5% on in-game arbs. Once you are executing consistently and in-game arbs are the constraint on your volume, the upgrade to the premium tier becomes straightforward to justify on bankroll maths.

Does OddsShopper include a promo converter or API?

OddsShopper does not include a promo converter or developer API access. The platform is built for individual manual execution — you see the opportunity, use the built-in calculator, and place both sides yourself.

If you want automated programmatic access to odds data, OddsJam is the US-market option with a full REST API. If you want promo conversion, ProfitDuel covers US markets with a dedicated free-bet converter.

How to sign up, set up and profit with OddsShopper

  1. Open the tool -- no sign-up needed for free features

    Use the link on this page. The Arbitrage Finder, Odds Screen, and Calculators are free immediately.

    • The Arbitrage tab shows pre-match and live in-game arbs. Free tier surfaces margins up to ~5% on in-game.
    • Sort the arb feed by profit % and set a minimum -- chase only the higher-margin arbs (say 3% and up) instead of scrolling past low-value ones.
    • The Odds Screen shows real-time odds across 110+ books for any market.
    • No bookmaker filter setup needed for the free tier -- all US books are shown by default.
    • For the premium Portfolio EV tool, sign up with an email -- no credit card required.
  2. Pre-match arbs -- start here to learn execution

    Pre-match arbs appear hours before events and stay open long enough to verify and act.

    • Each row shows: two sportsbooks, odds on each side, margin %, and a stake calculator.
    • Enter your total stake in the Calculators tab to get the exact split for each side.
    • Open both sportsbooks in separate browser tabs. Confirm odds are still live before placing.
    • Start with round stakes ($50-$100) while building execution speed.
  3. Live in-game arbs -- the highest margins, but fast

    The live tab surfaces arbs up to ~5% free, 8-10% on premium. Windows close within minutes.

    • Free tier: in-game arbs up to ~5%. Act within 2-3 minutes of the alert.
    • Premium (Portfolio EV): unlocks 8-10% in-game arbs. These require immediate action -- under 60 seconds.
    • Have both sportsbook accounts open before switching to the live feed. Speed is the constraint.
    • The Liquidity Tool shows how much can be staked before the price moves -- check it before sizing large.
  4. Parlay Builder and Pickem Builder

    Two free tools that use the OddsShopper odds screen to build bets at the best available price.

    • Parlay Builder: enter your selections and it shows the best combined odds across 110+ books.
    • Pickem Builder: builds best-odds pick-em entries using the same odds feed.
    • Both tools are free and require no sign-up.
    • Use them alongside the arb feed to maximise value on every bet, not just arbs.
