How do prediction markets differ from options markets?
A prediction market contract pays a fixed amount if a specific event happens and nothing if it does not, while an option's value depends on where an underlying asset's price ends up, so the payoff is continuous rather than all-or-nothing.
Detailed Explanation
Discrete vs continuous payoff. A binary prediction contract resolves to a fixed value, usually one unit, on a yes outcome and zero on a no. An option's payoff scales with how far the underlying moves past the strike. That single difference drives most of the others.
Price as probability vs price as premium. A prediction market price reads directly as an implied probability. An option premium blends probability, time value, volatility, and the distance to the strike, so you cannot read it as a clean probability. See how to read a price as a probability.
What you are expressing. Prediction markets express a view on whether an event occurs. Options express a view on magnitude and timing of a price move, with leverage and convexity built in.
Resolution and settlement. Prediction contracts settle on a written rule tied to a real-world outcome. Options settle against the underlying's price at expiry. The resolution-rule discipline of prediction markets is its own topic. See how settlement works and why rules matter.
Common Scenarios
- Choosing a prediction contract when your view is "will this event happen," not "how far will the price move"
- Choosing options when you want exposure to magnitude, leverage, or volatility
- Using a prediction market to read the crowd's probability, then expressing the trade in options if you want convexity
Exceptions & Edge Cases
- Some event outcomes can be expressed in either venue, so compare cost, liquidity, and resolution clarity before choosing.
- Options give you greeks and hedging flexibility that binaries do not.
- Prediction markets often cover non-financial events that options simply do not address.
Practical Examples
Comparison task: "Express a view that a company clears a regulatory hurdle."
- A prediction contract pays fixed on approval, reading directly as approval odds
- An equity option pays based on where the stock trades after the decision, blending probability with the size of the move
- Pick the venue that matches whether you care about the event or the magnitude
Actionable Takeaways
- ✅ Use binaries for event yes or no questions
- ✅ Use options for magnitude, leverage, and volatility views
- ✅ Read a prediction price as probability, not premium
- ✅ Compare liquidity and resolution clarity before choosing a venue
