Arbitrage Made Simple: Profit When the Books Disagree
Sports betting arbitrage guarantees profits by betting on all possible outcomes of an event using odds discrepancies between sportsbooks. For example, if one sportsbook offers +110 on Team A and another offers +110 on Team B, betting $100 on each ensures a $10 profit, no matter who wins.

Arbitrage betting requires speed, preparation, and discipline, but with the right tools and strategies, it can deliver consistent returns.

The Math Behind Arbitrage Betting
To successfully spot arbitrage opportunities, you’ll need to calculate implied probabilities and compare sportsbook odds. Let’s break this down step-by-step.
Converting American to Decimal Odds
First, you’ll need to convert American odds into decimal format. Here’s how:
-
For negative American odds:
Use the formula: (100 ÷ |odds|) + 1
Example: For -150, the calculation is (100 ÷ 150) + 1 = 1.67 -
For positive American odds:
Use the formula: (odds ÷ 100) + 1
Example: For +200, the calculation is (200 ÷ 100) + 1 = 3.00
Identifying Arbitrage Opportunities
Arbitrage opportunities arise when the combined implied probabilities from different sportsbooks add up to less than 100%.
To calculate implied probability:
- For decimal odds: (1 ÷ odds) × 100
- For negative American odds: (|odds| ÷ (|odds| + 100)) × 100
- For positive American odds: (100 ÷ (odds + 100)) × 100
Here’s a real example from March 2023:
- Sportsbook A: Over 4.5 goals at +250 (3.5 decimal)
- Sportsbook B: Under 4.5 goals at -120 (1.8 decimal)
Implied probabilities:
- Over 4.5: (1 ÷ 3.5) × 100 ≈ 28.57%
- Under 4.5: (1 ÷ 1.8) × 100 ≈ 55.56%
- Combined total: 28.57% + 55.56% = 84.13%
Since the total is less than 100%, this is an arbitrage opportunity.
Calculating Optimal Stakes and Profits
Once you’ve identified an arbitrage opportunity, the next step is to calculate how much to stake on each outcome. Use this formula:
Stake = (Total Investment × Implied Probability) ÷ Total Implied Probability
Let’s say you’re investing $1,000 in the example above:
- Over 4.5 stake: ($1,000 × 28.57%) ÷ 84.13% ≈ $339.54
- Under 4.5 stake: ($1,000 × 55.56%) ÷ 84.13% ≈ $660.46
Guaranteed profit:
- If the Over 4.5 bet wins: $339.54 × 3.5 = $1,188.39 (profit ≈ $188.39)
- If the Under 4.5 bet wins: $660.46 × 1.8 = $1,188.83 (profit ≈ $188.83)
This ensures a profit regardless of the outcome.
To make these calculations easier, tools like BetterSlip's Profit Lab can automate the process. With these steps, you’re ready to dive into arbitrage betting and place your bets with confidence.
Software and Tools for Arbitrage
Live Odds Monitoring
BetterSlip's Profit Lab takes arbitrage detection to the next level with its fast and efficient odds scanning system. By keeping tabs on odds from over 75 sportsbooks and refreshing them frequently, the platform ensures users can spot fleeting opportunities in volatile markets.
The interface uses a color-coded system to make potential arbitrage situations easy to identify at a glance. For pre-game markets, the tool automatically calculates key metrics like implied probabilities, total arbitrage percentage, recommended stake distribution, and expected profit margins. In live betting markets, where timing is critical, the platform accounts for the typical 5–10 second delay in bet acceptance. This timing mechanism helps users secure bets before odds shift. Additionally, users can configure custom alerts for real-time updates tailored to their preferences.
Setting Up Alert Systems
Customizing your arbitrage alerts is essential for staying ahead without being overwhelmed. BetterSlip's alert system allows users to set preferences based on profit thresholds, specific sports, and leagues. This flexibility ensures faster reactions during live betting and effective planning for pre-game markets.
For pre-game opportunities, lower profit thresholds and longer response times may work well. On the other hand, live betting often requires higher thresholds and quicker execution. Tailoring these settings can make a significant difference in capturing profitable opportunities.
NBA Arbitrage Example
Here’s how it works in practice: during an NBA game on May 14, 2025, between the Lakers and the Celtics, BetterSlip's Profit Lab flagged a 3.8% arbitrage opportunity across several major sportsbooks. By investing $1,000, users could secure a guaranteed profit of about $38, no matter the game's outcome. Using the platform's Quick Bet feature, bets were placed in just 7 seconds through direct deep-linking, ensuring the opportunity was captured before any odds adjustments occurred.

This tool instantly determines the optimal stake amounts across multiple sportsbooks, cutting out the need for manual math and reducing the chance of errors.

Handling Common Challenges
Arbitrage betting isn’t without its hurdles, but BetterSlip has built-in features to tackle them:
- Real-time odds verification ensures you’re working with the latest data, even as odds shift during placement.
- Instant stake recalculations help you adjust if a bet is only partially accepted.
- A safety buffer for live betting accounts for timing delays.
- API notifications alert you immediately if a bet is rejected or partially accepted.
To avoid delays, it’s crucial to maintain pre-funded accounts across multiple sportsbooks. BetterSlip’s bankroll tracking keeps tabs on your available funds across all connected accounts, ensuring you’re always ready to jump on profitable opportunities.
Risk Management in Arbitrage
Bankroll Distribution
Managing your bankroll wisely is the cornerstone of successful arbitrage betting. A solid approach involves using a reliable stake calculator and sticking to a consistent staking plan. Here’s how you can do it:
- Stick to a flat stake of 5–6% of your total bankroll for each arbitrage opportunity.
- Always keep a portion of your bankroll as a reserve for unexpected situations.
- Spread your funds across multiple sportsbooks to ensure quick access when opportunities arise.
For example, if your bankroll is $10,000, placing flat bets of $500–$600 per opportunity is a practical strategy. Tools like the Bankroll Tracker can help you monitor your funds automatically, reducing the risk of overexposure to any single sportsbook.
A well-balanced bankroll is the foundation for minimizing risks and maximizing long-term gains.
Risk Prevention Steps
To avoid common pitfalls in arbitrage betting, take advantage of built-in safety tools and follow these guidelines:
-
Odds Verification System
Double-check the current odds and flag any unusual changes. This helps ensure compliance with game rules, including overtime policies. -
Account Protection Protocol
- Keep your arbitrage stakes below 70% of the sportsbook’s maximum allowed limits.
- Avoid arbitrage opportunities with returns higher than 3% in pre-match markets, as they may attract unwanted attention.
- Space out your withdrawals to reduce the chances of triggering account reviews.
By following these steps, you can safeguard your accounts and maintain a low-risk profile.
Performance Analysis
Consistently reviewing your performance is crucial for refining your strategy. Analytics tools can provide detailed insights into your arbitrage activities. For instance, the ROI Tracker calculates key metrics and highlights areas for improvement. If you notice slower execution speeds, consider these adjustments:
- Pre-fund accounts that frequently present opportunities to reduce delays.
- Simplify verification processes to save time during transactions.
- Set up custom alerts for specific odds ranges to act quickly on favorable opportunities.
Regular performance analysis ensures you stay efficient and adaptable in the ever-changing arbitrage landscape.
