Built for headline-driven policy setups where pricing, probability, and execution friction matter more than narrative confidence alone.
About This Calculator: Prediction Market Policy-Risk (EV, Break-even Probability)
Why: Event contracts can look attractive while hiding poor expected value after friction.

How to Use This Calculator
Use this tool for scenario planning, not certainty. Policy outcomes and market structure can change quickly.
Formulas Used
expectedNet = [p(win) * payoutIfWin * contracts - capital] - friction
breakEvenProbability = (capital + friction) / (contracts * payoutIfWin)
What is this calculator for?
It models prediction-market style position outcomes when policy or regulatory headlines can change expected payoffs and holding windows.
Why include probability-adjusted payoff?
Event contracts are often binary-like. Expected value = win payoff x probability minus lose payoff x (1-probability), before fees.
How does regulation risk fit?
Legislative risk can reduce liquidity, widen spreads, and force exits. The fee/slippage field is a simple proxy for that friction.
What reporting informed context?
Public coverage around 2026 proposals to restrict prediction-market trading by senior officials informs the narrative context only.
Does this predict bill passage?
No. You enter your own probability assumptions and scenario prices.
Is this advice?
No. Educational only.
