Edge is the difference between our model's fair probability and the implied probability from sportsbook odds. A +3% edge means we calculate 53% win probability where the book prices only 50%.
Reading the Value Finder
The Value Finder ranks bets by edge. Higher edge = more value. Use Kelly Criterion sizing to determine stake. Green = strong value, yellow = moderate.
Set Your Bankroll
Enter your bankroll above to get Kelly-sized bet recommendations. Start conservative — we suggest 25% Kelly (quarter Kelly) for new bettors.

Kelly stakes
The Kelly Criterion tells you what fraction of your bankroll to bet to maximise long-term growth.
Kelly % = (b × p − q) / b
b = decimal odds − 1 p = true win probability q = 1 − p
Half-Kelly used here
50% of full Kelly — reduces variance while preserving most of the edge. Most professional bettors use half-Kelly or quarter-Kelly.
