Event Contract Margin & Liquidation Lab
Kalshi's petition to the CFTC to permit margin on prediction markets introduces leverage to binary 0¢–100¢ event contracts. Simulate your equity requirements, maintenance margin call levels, interest carry decay, and automated liquidation boundaries.
Comparing outcomes between standard 100% cash-collateralized trading versus CFTC margin borrowing.

Key Mechanics of Prediction Market Leverage
⚖️ Binary Payout Boundary Discontinuity
Unlike equities or commodities which can trade smoothly, event contracts abruptly settle at exactly $1.00 (100¢) or $0.00 (0¢).
Because maximum contract value is strictly bounded at $1.00, high leverage near low prices creates severe asymmetric default risk for clearinghouses, requiring dynamic margin schedules.
📉 The Speed of Margin Liquidation
With 2.5x leverage (40% initial margin), a mere 15¢ drop in market probability on a 60¢ contract consumes over 60% of your initial equity. If the market approaches your maintenance margin threshold, the platform must auction your contracts immediately to protect the clearinghouse from taking bad debt.
⏱️ Financing Carry on Fixed-Yield Bets
If you buy 5,000 contracts at 62¢ on margin, you are borrowing cash against a maximum terminal upside of 38¢ per share. If the contract takes 90 days to resolve, margin interest reduces your net percentage return, meaning leverage is best suited for short-duration event convergence.
