Probability pricing

Outcome shares trade between $0.00 and $1.00. The price is the market-implied probability.

  • $0.25 implies ~25%
  • $0.70 implies ~70%

Payout logic

  • Winning outcome share: $1.00
  • Losing outcome share: $0.00

Example: buying at $0.40 gives up to $0.60 upside per winning share.

Why prices change

  • New information enters the market.
  • Buy/sell pressure shifts bids and asks.
  • Liquidity depth changes execution quality.

Order-book signals to watch

  • Best bid/ask: nearest executable prices.
  • Spread: narrower spread usually means cleaner fills.
  • Midpoint: quick fair-value reference between bid and ask.
