OddsPortal vs ArbVantage: research tool or sure-bet scanner?
OddsPortal is one of the best-known odds-comparison sites, with years of archived odds, dropping-odds lists and a short free list of sure bets. ArbVantage is a dedicated sure-bet scanner. The two overlap less than the names suggest: one is excellent for research and history, the other for acting on opportunities today.

Where OddsPortal is strong: research and history
OddsPortal's archive is its biggest strength. You can see how odds for a match moved and what the closing prices were, across many leagues and seasons. That is valuable for:
- Checking your own bets against the closing price, the idea behind closing line value.
- Spotting market moves with its dropping-odds lists; see dropping odds explained.
- Finding the best price before an ordinary bet, also called line shopping.
A team opens at 2.20 and closes at 1.95. The implied probability rose from 1 ÷ 2.20 = 45.5% to 1 ÷ 1.95 = 51.3%. If you had bet at 2.20, your price was 2.20 ÷ 1.95 − 1 = 12.8% better than the close. That says something about the quality of your price, not about whether the bet won.
ArbVantage has no public odds archive. If research and history are what you need, OddsPortal is the better tool, and it is free.
What its sure-bets list does and doesn't do
OddsPortal shows the top 10 sure bets for today and the coming days for free. The page itself warns that sure bets might not last long and that odds can change rapidly. For more than ten, its "Get more" link leads to a professional sure-bets page that points to a partner, RebelBetting; OddsPortal states that it does not operate that software. We compare RebelBetting separately in ArbVantage vs RebelBetting.
Ten opportunities across all bookmakers is a good way to see what sure bets look like. For a beginner in Austria or Slovakia, the catch is that many of them will be at bookmakers you don't hold or that don't serve your country, so the usable number is often much lower.
Say a list shows a sure bet with 2.30 at bookmaker A and 1.85 at bookmaker B: 43.48% + 54.05% = 97.53%, about 2.5% left over. With €250 in total you would stake €111.45 at A and €138.55 at B for about €256.33 either way, roughly €6.33.
If you have no account at B, or B doesn't accept customers from your country, the opportunity is worth €0 to you. That is why ArbVantage starts from the bookmakers you actually hold.
Acting on opportunities today
ArbVantage is built for the moment between "there is a price difference" and "both bets are placed". It shows only bookmakers you have accounts with, works out and rounds the stakes, shows the age of every price and hides stale ones, and can send a push alert to your phone when a saved filter matches. Your bets and balances per bookmaker stay in the same app. Native iOS and Android apps are in development.
We are open about coverage. From Austria, the bookmakers in our feed that matter most today are Tipico and William Hill; Admiral, bwin, Interwetten, tipp3 and bet-at-home follow with a second odds source, and Slovak licensees such as Tipsport, Fortuna and Niké are not in our feed yet either. On the Austrian 5% Wettgebühr: we price the fee in for bookmakers known to pass it on; none of the bookmakers in today's feed does. Check each bookmaker yourself.
A fee only makes sense if you use it. At a 1% average net margin (our model's assumption), €97 a month needs about €9,700 in total stakes to be covered. That is an illustration, not a forecast; real results vary and can be negative, because odds move, bets get voided and accounts get limited.
Which suits whom
- OddsPortal suits you if you want free odds comparison, historical odds and closing prices, dropping-odds lists and a quick look at a few sure bets.
- ArbVantage suits you if you want to act on sure bets and middles at your own bookmakers, with stakes worked out, push alerts and an interface in German or Slovak, focused on Austria and Slovakia.
Many people use both: OddsPortal for research, a scanner for opportunities. More in odds comparison vs arbitrage scanner.
Frequently asked questions
Are OddsPortal surebets free?
Yes. OddsPortal shows the top 10 sure bets for today and the coming days for free. For more, it points to a partner's paid service, which it states it does not operate.
Does OddsPortal have its own paid surebet scanner?
When we checked in October 2026, its professional sure-bets page pointed to a partner service rather than an OddsPortal product. Check the provider's page for the current situation.
What is OddsPortal best used for?
Research: historical odds, closing prices, dropping odds and comparing prices before a bet. ArbVantage has no public odds archive; it is built to find current sure bets at your bookmakers and work out the stakes.
Can I use OddsPortal and ArbVantage together?
Yes. Many bettors use an odds archive to check prices and closing lines, and a scanner to find and place sure bets. The tools answer different questions.
