Small edges can create strong value in parlays.

Recreational parlay
High margin / poor pricing
→
Final EV
-28%

Bookmaker margin multiplies on every additional leg.

Small differences compound aggressively in parlays -- for better or worse.

4. REALITY CHECK
  • Parlays increase variance dramatically.
  • Margin compounds on every leg.
  • Most recreational parlays are negative EV.
  • Sharp parlays exist -- but require pricing discipline.
The payout alone means nothing.

Only the relationship between fair odds and book odds determines value.
