Understanding Odds & Spreads

Prediction markets price outcomes between 0 and 100 (representing probability). However, different platforms display this differently. Oraclyst normalizes everything.

The Normalized View:

• Price: Displayed in cents ($0.00 to $1.00).

• Probability: Displayed as a percentage (0% to 100%).

The Spread: The "Spread" in Oraclyst refers to the difference between the Buy Price of an outcome and the Sell Price of that same outcome, potentially across different venues.

• Venue Spread: The difference between the highest bid and lowest ask on a single platform.

• Cross-Venue Spread (Arbitrage): The difference between the price of "YES" on Venue A and the price of "NO" on Venue B.

  • Rule of Thumb: If Price(Venue A, YES) + Price(Venue B, NO) < $1.00, an arbitrage opportunity exists. Oraclyst highlights these in Gold.
