Illustrative maths, not a recommendation
Back illustration
At decimal odds of 2.50, a ₹100 matched stake has a gross potential return of ₹250, including the ₹100 stake. The loss if unsuccessful is ₹100.
Lay illustration
Laying ₹100 at decimal odds of 2.50 creates ₹150 liability: (2.50 − 1) × ₹100. The displayed “stake” is not the full amount at risk.
Actual rules, rounding, commission, voids and settlement vary. Illustrations do not imply that any platform or transaction is available or lawful.
Operational risks
- Partial matching can leave a smaller or differently priced position than expected.
- Live-market delays can change what is accepted.
- Rules may treat ties, abandoned events and corrections differently.
- Agent-created accounts can obscure who is responsible for balances.
- A familiar exchange interface does not verify the underlying operator.
Questions readers ask
Are exchange odds guaranteed?
No. Available prices and liquidity can change, and an order may be unmatched or partially matched.
Can a lay loss exceed the stake shown?
Yes. Liability depends on the odds and lay stake, so it can be larger than the nominal stake.
Is an exchange the same as investing?
No. Similar interface language does not change the underlying activity from wagering on uncertain outcomes.
