Public Opinion as an Option: Leveraging Prediction Markets to Hedge Exposure to Spot Crypto Volatility

Battle Count: 68

Highly relevant to quantitative trading as it presents a novel hedging framework using prediction markets as synthetic options. The dynamic signal-based rebalancing strategy, mispricing detection via Black-Scholes vs. market-implied probabilities, and risk metric evaluation (Sharpe, VaR, CVaR, drawdown) are directly applicable to crypto portfolio management. However, practical implementation is constrained by Kalshi's fee structure, limited liquidity, and regulatory uncertainty.

Moderate complexity. Requires understanding of Black-Scholes probability derivation, signal generation logic, portfolio rebalancing mechanics, and Kalshi API integration. The core algorithm (mispricing detection + five-level signal + periodic rebalancing) is conceptually straightforward, but production deployment requires handling real-time data feeds, order execution, fee optimization, and liquidity constraints. No code is provided.

Data sources are identified (Binance API for BTC OHLCV, Kalshi for event contract prices). Methodology is described with formulas and parameters. However, no code repository is provided, Kalshi historical data access may be limited, and specific implementation details (e.g., exact rebalancing logic, signal sampling code) are not fully specified. The three Kalshi markets tested are identified with URLs.
