Arbitrage betting: how to find arbs with SureBet
An arbitrage bet (arb, or surebet) is a set of bets on every outcome of a game, placed at different sportsbooks, where the combined prices leave a positive margin whatever the result. NinjaBet's SureBet scanner compares live prices across licensed US sportsbooks and lists the arbs with a 1–3% margin, stakes already calculated.


How it works in 3 steps
- 1
Open the scanner and set your filters
Choose the sportsbooks where you hold an account, the sport and the minimum margin. The scanner refreshes constantly and sorts SureBets by margin.
- 2
Check prices and rules
Confirm the prices are still available and that the market rules match (tennis retirements, for example). The calculator splits the stakes automatically.
- 3
Place the bets and log the result
Bet on every outcome at the same time and save the operation in the Bet Tracker. The margin adds up bet after bet.

Frequently asked questions
What is a SureBet?
A situation where two or more sportsbooks price the same game so differently that covering every outcome leaves a positive margin regardless of the result.
How much can you make with SureBets?
Each SureBet leaves on average 1–3% of the stake. The monthly result depends on your capital and the number of operations: many users start at $300–$1,000 a month.
Are there risks?
The main risks are a price moving before all bets are placed, a stake mistake, and the limits sportsbooks apply to arbitrage bettors. The guides explain how to reduce them.
Do I need a lot of capital?
The more capital, the more operations. People start with a few hundred dollars spread across accounts; margins grow with volume.
Can I combine SureBets and Matched Betting?
Yes: many users start with Matched Betting bonuses and move to SureBets to grow their capital. The two tools are separate subscriptions or one complete plan.
