What does a +12.7% edge mean?

A positive edge of +12.7% means the price (+130) pays more than the fair price (+104). 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 43.5% 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 49.0%, which converts to fair odds of +104.

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 A+-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This parlay offers a slight edge at the offered price.

Market context: DraftKings' offer at +130 is superior to the original price of +100, showing a 15.0% price improvement.
Status: No notable injury signal.
Social: the matchup public social data for analysis.
Risk: This is a four-leg parlay, inherently carrying multi-leg parlay variance.

Smart insight: Vinicius the matchup shot volume is a key driver for this bet's expected value. Similar profile: This is a 4-leg SGP combining a moneyline, total goals band, and two player props, a profile that can be prone to perceived value due to market inefficiencies. Counter-case: the matchup parlays, especially those incorporating specific player props, are highly susceptible to variance. Live context: the matchup lineups near tip-off.

Recommendation: Small

How this bet was graded

Grade A+ · 76/100 · Lottery Ticket

Same Game Parlay: Brazil Moneyline, 1-4 Total Goals Bands - Away Team, Vinicius Jr 1+ Shot in 1st Half, Vinicius Jr 1+ Shot On Target at +130 on DraftKings (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 (+15.0%), 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. A+ (76/100) 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 A+-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.
