Parlay Bankroll & Sizing Tips
🛠️ Tools & FeaturesParlays are high-risk, high-reward. Smart sizing makes the difference between entertainment and reckless gambling.
The Golden Rule
Why so small? Because a 3-leg parlay at -110 each only hits ~12.5% of the time. You need to survive the 87.5% of the time it loses. [/example]
When Parlays Make Mathematical Sense
Parlays are NOT inherently bad. They make sense when:
- •Each leg has positive expected value (+EV)
- •Legs are positively correlated (one winning helps the others)
- •The parlay payout doesn't have excessive vig
The AI Parlay Builder only selects +EV legs, which makes the combined parlay much better than random parlays.
When to Avoid Parlays
⚠️ Avoid parlays when you're chasing losses, when legs are uncorrelated longshots, or when a sportsbook is offering "boosted" parlays that look too good (they usually have terrible alternate legs baked in).
Comparing Straight Bets vs Parlays
$100 on a 3-leg parlay of those same bets: Expected profit: ~$10 (but you either win ~$500 or lose $100) [/example]
Straight bets are mathematically slightly better because parlay payouts include extra vig. But if all legs are +EV, the parlay is still +EV overall.
Use the Kelly Calculator for straight bets and limit parlays to 0.5–1% of bankroll. Track your parlay results in the Bet Tracker to see your actual hit rate over time.
