What does a +9.1% edge mean?

A positive edge of +9.1% means the price (+2800) pays more than the fair price (+2558). Over many identical bets, that gap is your expected return per dollar staked.

Does a positive edge mean the bet is likely to win?

No. The market still implies about a 3.4% chance this hits at the offered odds. A +EV bet pays more than its true probability warrants — most +EV bets at long odds still lose individually.

How are fair odds calculated?

Sportsbook prices on the same market are de-vigged and averaged to estimate a true win probability. Using the available market price, we estimate 3.8%, which converts to fair odds of +2558.

Why does this grade differ from the sportsbook's advertised lift?

Books quote lifts vs their own original line, which already includes margin. We compare the price to a vig-free consensus, so an advertised lift can still grade poorly if the underlying line was inflated.

Should I bet every bet that grades well?

Grading is a price-quality signal, not a guarantee. Even a B-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This boost offers a notable edge, driven by favorable pricing compared to fair odds.

Market context: The boosted odds of +2800 significantly outpace the devigged an estimated fair price, offering a strong advantage over the original +2500.
Status: No notable injury signal.
Social: the matchup data to assess social sentiment.
Risk: This is a 4-leg parlay, inherently carrying high multi-leg parlay variance.

Smart insight: The value of this bet is highly sensitive to the true probabilities of each leg, with all four legs needing to hit for a payout. Similar profile: This is a 4-leg soccer SGP involving money line and various statistical superlatives, a profile that often resolves with significant variance. Counter-case: The longshot nature of a 4-leg parlay means a high probability of not hitting, regardless of the edge. Live context: the matchup lineups near tip-off.

Recommendation: Standard

How this bet was graded

Grade B · 67/100 · Lottery Ticket

Switzerland v Canada at +2800 on Bet365 (4 legs): we couldn't match this slip to enough comparable market prices to compute a trustworthy consensus fair value, so no edge % is shown — anything we'd print would just echo the book's own vig. The grade leans on price lift vs the original (+11.5%), leg count, and variance. Treat it as directional.

Frequently asked questions

Why isn't an edge % shown?

We couldn't match this slip to enough comparable market prices to compute a trustworthy fair value. Rather than show a number derived from the offered price itself (which would just echo the book's vig), we leave the edge unstated. The grade still reflects price lift vs the original, variance, and confidence.

Does the grade still mean something?

Yes. B (67/100) is built from the price lift, leg count, variance, and any verified context signals — it's directional. Treat it as a sanity check, not a precise EV figure.

Should I bet every A-grade ticket?

Grading is a price-quality signal, not a prediction. Even an B-grade ticket can lose. Size within your bankroll, account for correlation between legs, and use Inside Angles above to spot factors the price hasn't absorbed yet.
