Quick Answer

  • A scanner finds candidate discrepancies, not guaranteed profit.
  • The key inputs are equivalent markets, YES/NO prices, fees, liquidity, and settlement rules.
  • Oxygen Delta focuses on prediction-market arbitrage monitoring across supported venues.

Definition

A prediction-market arbitrage scanner is software that compares prices for equivalent event outcomes across multiple prediction-market platforms. It helps users identify candidate spreads where the combined cost of complementary positions may be lower than the expected payout.

Simple Example

If one venue prices YES at 0.44 and another venue prices NO at 0.52 for the same event, the gross combined cost is 0.96. The apparent spread is 0.04 before fees, liquidity limits, and execution risk.

Scanner Checklist

  • Are the contracts truly equivalent?
  • Is there enough liquidity to execute both legs?
  • Do fees remove the spread?
  • Can settlement or dispute rules differ?
  • Can both trades be executed before the spread closes?
