Outcome Shares
Outcome shares are the tradeable Yes and No units of a prediction market whose prices sum to about one and pay a fixed value if correct.
What it means in practice
Outcome shares are the tradeable units of a prediction market, typically issued as paired Yes and No shares whose prices sum to roughly $1. A trader who buys a Yes share at $0.62 is paying a price that implies a 62% market probability of the event, and that share pays $1 if the event resolves Yes and 0 if it does not. The No share for the same event would trade near $0.38, so the pair covers both sides of the outcome.
Because the price of an outcome share maps directly to a probability, traders read it as a live implied probability rather than as decimal betting odds. The gap between the highest bid and the lowest ask is the bid/ask spread, which widens in thin markets and tightens as more participants quote. Each event contract is composed of these shares, so they are the smallest unit an operator and an affiliate can track.
On exchange venues the shares change hands through a central limit order book, matching buyers and sellers by price-time priority. The operator earns prediction-market trading fees on the volume of shares that trade rather than taking the other side of the position. Higher share turnover therefore raises both platform revenue and the prediction-market liquidity available to new traders.
For partner programs, outcome-share volume is the metric that drives revenue share, because affiliate revshare is calculated on the fees those traded shares generate. Clean per-share and per-contract reporting lets an operator attribute trading activity back to the referring partner over the full life of an account. This makes outcome shares the natural unit of measurement for prediction-market commission.
