How Much Should You Risk Per Operation?
Learn how to size your arbitrage positions, manage capital exposure, and establish practical limits that help protect your bankroll.
Understanding Exposure
Per Operation
In sports arbitrage, your total stake is the combined amount placed across all outcomes of an event. Although a correctly executed arbitrage may produce a positive theoretical return, the capital involved remains exposed to operational and settlement risks.
Your exposure per operation is therefore different from the profit you expect to earn.
Practical Example
A $250 arbitrage operation represents 5% of a $5,000 bankroll, even when its expected profit is much smaller.
Setting a Maximum
Exposure Limit
An exposure limit establishes the maximum portion of your bankroll that you are willing to commit to a single operation.
A smaller limit may reduce the impact of a failed operation, while a larger limit concentrates more capital in one event. There is no universally safe percentage.

Calculate Your Stakes
Before Betting
Both stakes must be calculated together. Consider a two-outcome market with decimal odds of 2.10 and 2.05.
If the outcomes cover every relevant result and settlement rules are compatible, the stakes can be distributed to target approximately equal payouts.
Example — $200 Total Stake
| Outcome A — odds 2.10 | $98.80 |
| Outcome B — odds 2.05 | $101.20 |
| Approximate Payout | $207.48 |
| Approximate Theoretical Profit | $7.48 |
Before fees, rounding, taxes, execution differences, and settlement risks.

Managing Multiple
Open Operations
Several small operations can collectively commit a substantial portion of your bankroll. Track the combined value of unsettled bets, funds needed to complete pending operations, and capital still available.
Establish a separate limit for total simultaneous exposure, not just individual operations.
Example: Three Simultaneous Operations
| Operation 1 | $200 |
| Operation 2 | $150 |
| Operation 3 | $250 |
| Total Committed | $600 (12%) |
Based on a $5,000 bankroll. Committed capital is not necessarily the amount that would be lost if an issue occurs.
