Can you show me a working example of a sports arbitrage opportunity and how the investment would be staked?


A real sports arbitrage opportunity from 14th August 2018 is shown below:

Real Life Example Arb:

WNBA Basketball Match

Under 79 Points » 1.82 (Unibet) » £58.35 returns £106.20
Over 79 Points » 2.55 (Sportingbet) » £41.65 returns £106.21

Notes: Second Half. Los Angeles Sparks W vs. New York Liberty W

Total arb / surebet profit : 6.201%

A correctly staked investment of £100 guarantees a return of £106.20 no matter the outcome. That's £6.20 profit due to discrepancies in the bookmakers' odds, guaranteeing a 6.201% profit on your investment in under 24 hours!

The above information tells us that a betting market exists on the WNBA Basketball Match between Los Angeles Sparks W and New York Liberty W. It also tells us that Unibet have odds of 1.82 for Under 79 Points, and that Sportingbet have odds of 2.55 for Over 79 Points.

By applying a simple mathematical formula to those odds, we are able to calculate that we can cover all possible outcomes of the match and make a guaranteed 6.201% return on our investment.

We would invest our money in proportion to the odds on each possibility. The amount to invest on each outcome is calculated using another simple formula. £58.35 invested on Under 79 Points returns £106.20, and £41.65 invested on Over 79 Points returns £106.21.

£58.35 x 1.82 = £106.20
£41.65 x 2.55 = £106.21

Risk free profit = £6.20

"I started with a bank of about £400, and after receiving your arbitrage alerts for 8 months later that's grown to £1,152 - much better than my high street bank could do!

I don't use all the arb alerts that I receive because I just don't have the time but if I could use them all, who knows how much profit I would have made!"
