Sure Betting: Simplified by Oddsbandit

Turning price gaps into hedged returns

📚 8 min read•Last updated: January 2025

Sure betting is the sports-betting practice of backing all outcomes of the same market at different bookmakers when their prices diverge enough to create a built-in edge. You're not predicting a winner—you're exploiting a price gap and balancing stakes so the payout is effectively the same whoever wins, provided both legs are placed and the markets match.

In reality, results hinge on clean execution: match identical market rules (e.g., whether overtime counts), move fast before prices update, respect stake limits and rounding, and keep an eye on any fees. Done right, sure betting delivers hedged, low-variance returns where turnover and precision matter more than hot streaks or hunches.

Quick takeaway: Sure betting means the sum of implied probabilities across all outcomes (at different bookmakers) is below 100%—so by balancing stakes you lock in a hedged profit regardless of the result (assuming matching market rules and both legs placed).

Sure Betting vs. Arbitrage — What's the Difference?

Short answer: there isn't one in sports betting. "Sure betting," "arbitrage betting," and "arbs" all mean the same thing: backing all outcomes of the same market at different bookmakers when prices diverge enough that the combined implied probability is under 100%. You then balance stakes so the payout is effectively the same whichever outcome lands—assuming identical market rules and both legs are placed.

The Math Behind It

When the sum of inverse odds is less than 1.00, you have an arbitrage opportunity:

1/Odds₁ + 1/Odds₂ < 1.00 = Surebet ✓

Sure Betting Example: Step-by-Step

1

Identify the Price Gap

We found a soccer match between Team A and Team B with a clear price gap across bookmakers. On Bookmaker 1, Team A is 2.50; on Bookmaker 2, Team B is 1.81. The combined implied probability is under 100%, yielding an arbitrage margin of roughly 4.8–5.0%.

Bookmaker 1
Team A @ 2.50
Implied probability: 40%
Bookmaker 2
Team B @ 1.81
Implied probability: 55.25%
1/2.50 + 1/1.81 = 0.40 + 0.5525 = 0.9525 < 1.00 ✓
2

Balance the Position

To balance the position, stake $100 on Team A at 2.50 and $138 on Team B at 1.81 (total $238 invested).

Stake on Team ABookmaker 1
$100 @ 2.50
Potential payout: $250
Stake on Team BBookmaker 2
$138 @ 1.81
Potential payout: $249.78
3

Lock in Guaranteed Profit

Either way, you lock in about $12 profit (≈ 5% ROI), assuming identical market rules and both legs are placed.

If Team A wins
+$12 profit
$250 payout - $238 total stake
If Team B wins
+$11.78 profit
$249.78 payout - $238 total stake
ROI: ~5% guaranteed regardless of outcome

How to Stay Under the Radar with Sure Betting

While sure betting is mathematically guaranteed to profit, bookmakers aren't fond of arbitrage bettors. Here's how to maximize longevity and minimize account restrictions:

Skip the Fattest Arbs

The highest-percentage surebets are more likely to be voided or flagged. Prioritize modest, realistic edges to reduce scrutiny and keep your accounts healthy. A 2-3% return is safer than chasing 10%+ opportunities.

Round Your Stakes

Calculators spit out decimals (e.g., "Stake: 176.74"). Round to natural numbers (e.g., 180) that match typical user behavior and bookmaker increments—then recheck profit after rounding.

❌ Suspicious: $176.74✅ Natural: $180.00

Target Top-Tier Leagues

Stick to major, liquid competitions (e.g., Premier League, NBA, Champions League over Sweden's third tier). Prices move cleaner, limits are higher, and your action blends into a bigger crowd.

Pro tip: Mix in some regular bets alongside your arbs. Place occasional losing bets on popular markets to appear like a recreational bettor. This helps maintain account health and reduces the chance of limitations.
