Methodology

The math, in plain English.

Bookmakers price events to make money on the average bettor. Our models price the underlying probabilities. When the gap is big enough, that bet is +EV. Stake all sides across multiple books and you have arbitrage. Both compound over volume.

Positive EV

What is +EV?

FAIR2.00+0.10 edgeBOOK2.10

Imagine a coin flip. Fair odds for heads should be 2.00 — you bet $1, win $1.

Now imagine a bookmaker offers 2.10 odds on heads. Over many flips, you'd still win 50% of the time, but you'd be paid at 2.10. That extra 0.10 — the difference between fair and offered — is your edge.

We don't bet coin flips. We scan thousands of sports markets where bookmakers misprice odds, and surface those mispriced opportunities the moment they appear. That difference, over hundreds of bets per day, compounds into consistent profit.

Arbitrage

What is Arbitrage?

Two different bookmakers price the same event differently. Sometimes the gap is wide enough that betting BOTH outcomes — one at each bookmaker — guarantees a profit regardless of who wins.

When bookmakers misprice odds or stack promos against each other, returns can climb dramatically higher. Our system has flagged opportunities exceeding 100% on single events when conditions align.

Why volume matters more than any single bet

Variance dominates small samples. A +EV bet at +5% can lose ten times in a row before the math asserts itself. That's why we post 1,000+ bets per day across both feeds. The Law of Large Numbers applies: with enough bets at positive expectation, realised returns converge to expected returns.

Practical implication for the member: staking flat per bet at a small fraction of bankroll is how the math compounds. Most members size at 1–2% of bankroll per +EV pick, scaled by edge size via Kelly fractioning.

How we price probabilities

Our pricing models combine:

The output is a fair probability per outcome. We compare every book we cover against the fair price, every second. The gaps that clear our threshold are posted.

What we don't do

The concepts here are well-established in quantitative finance and sports analytics. Open primers we recommend:

The bookmaker prices the vig. The model prices the probability. When they disagree, that's the bet.
