Value betting vs arbitrage
Arbitrage locks a guaranteed-in-theory margin by covering all outcomes; value betting takes prices that beat fair odds and profits over the long run.
Arbitrage covers every outcome across books and the exchange so the result is irrelevant — a small, locked margin, but rare and short-lived. Value betting takes single prices that beat their fair odds and wins statistically over many bets, accepting variance on each one.
Both rely on wide, normalised coverage with a sharp reference. The difference is risk profile and frequency: arbitrage is rarer and lower-variance; value is more frequent and higher-variance.
Neither is guaranteed money — arbitrage is constrained by limits and price movement, value by variance and account restrictions.
