About

OptionBridge

Features
Read full description

OptionBridge is a professional-grade tool for traders who operate across both options markets and prediction markets. By extracting implied volatility from vanilla SPX options and applying Black-Scholes digital pricing, the app calculates the true risk-neutral probability of any Polymarket event — then compares it directly to the Yes/No contract price to reveal mispricing, edge size, and the optimal trade direction. Whether you're arbitraging between IBKR and Polymarket or simply stress-testing your probability assumptions, OptionBridge gives you institutional-quality analysis in seconds, directly from your iPhone.Privacy Policy: https://sites.google.com/view/optionbridge/home/privacy-policy| Terms of Use: https://sites.google.com/view/optionbridge/home/terms-of-use
