No prediction, no directional risk — the promo is the only variable left. Priced like a hedge, because it is one.
Back leg at the bookmaker, lay leg on the exchange, sized to net the same either way. The only unhedged variable is the promo itself. Repeatable across 219 licensed SA bookmakers.
Enter the bookie odds and your lay odds. We compute the exact lay stake so both outcomes give the same payout.
Position: back R 1 000 @ 2.5, lay R 657,89 @ 2.3 → net R 644,74, either outcome.
