OddsBoss arbitrage feed: pairs of bets at two sportsbooks, with the stake for each book and the profit if both bets fill
The arbitrage feed: both sides, both stakes and what comes back, for every pair.

How it works

Place two bets and collect. That's arbitrage.

Two books put different prices on the same bet, so you take one side at each. Stake it right and either result pays back more than you put in. You don't need to follow the team, or even the sport.

  • We find two books that disagree enough to cover both stakes.
  • We give you the exact bet size, then you place them at the two books.
  • One bet wins, one loses, and you keep the difference.
NBA · Total points 221.5 · Pre-match Example
  • Over 221.5Book A+140$214
  • Under 221.5Book B−125$286

You wager$500

You make$13–$15

+$13.60 to +$14.80 on $500, whichever side hits

$214 at +140 pays back $513.60. $286 at −125 pays back $514.80. You put in $500, so you keep $13.60 or $14.80, if both bets are placed at these prices.

We split it for you: 2.7% to 3.0% back whichever side hits.

Most arbs are small: usually 3% or less of what you stake.

71% SR on NFL in October

Not sure how other websites work but tbf it’s been pretty decent… you won’t earn millions but so far I had like 71% sr in October on NFL so it’s pretty decent considering the pricing.

Arb is pretty decent here. Would say that on average with good strategy you can get 7 to 12% daily but obviously sometimes it can be 6% too. So far I only made like $11k since 3 months but the more you can wage, the more you can make so maybe people with bigger budgets would be able to say something more.

Individual results. Results vary and no bet is guaranteed.

The catch

These plays disappear fast.

But OddsBoss is faster.

An arb only lasts while one book is slow to move its price. OddsBoss watches every line at your books, pre-match and live, and shows the pair as soon as it opens, with both stakes worked out.

Fair questions. Straight answers.

Some books will cut your max bet eventually. That's the honest answer. The fix is spreading your action: OddsBoss covers 17 books, and exchanges like Novig and ProphetX match you with other bettors, so winning isn't a reason to limit you. Promo conversion uses offers every new customer gets, so it's the least likely to get you limited.
