Bankroll Management bei Prediction Markets: Nie alles verlieren
The primary culprit behind skilled forecasters failing at prediction markets isn't typically flawed analysis—it's inadequate fund allocation. Even an exceptionally precise probability assessment becomes worthless if a single losing streak decimates your account balance.
Das Kelly-Kriterium: Die mathematische Grundlage
The Kelly formula establishes the theoretically ideal fraction of your bankroll to allocate per wager: f = (bp - q) / b
- b = Decimal odds minus one (for example, YES priced at 0,40 yields b = 1,5)
- p = your estimated probability
- q = 1 - p
Practically speaking: employ fractional Kelly sizing. Given inherent estimation variance, utilising half Kelly delivers superior risk-adjusted performance outcomes.
Eiserne Regeln: Niemals brechen
- Never commit more than 5% of your bankroll to any single position—without exception
- Limit correlated exposures (such as all US electoral markets) to 25% maximum
- Implement stop-loss discipline: cease trading for the remainder of the month upon losing 25% of opening capital
- Avoid averaging down into losing positions unless you've fundamentally reassessed your thesis
Erholung nach Drawdown
Following a 20% drawdown, scale back your position sizing by half until your account recovers to its previous peak.
Häufig gestellte Fragen
- Wie viel Startkapital brauche ich für ernsthaftes Prediction Market Trading?
- Between $500–$1,000 provides sufficient capital to maintain proper diversification across 10–20 positions using half-Kelly methodology. Below $100, exchange-imposed minimums obstruct disciplined position management.
- Was tun nach einer Gewinnserie?
- Increase caution, not confidence. Winning streaks breed complacency. Adhere rigorously to your sizing framework irrespective of recent results.
