Most prediction markets were built for questions that end in yes or no. Money questions end in a number, and that changes what the market has to do.
Scalar vs binary prediction markets
Binary markets ask which box a number landed in. Somebody drew those boxes, and it decides your whole payout.
How an order book works in a scalar market
Bids, asks, and the gap between them. What the spread costs you, and why one book beats several.
A prediction market example, from open to settlement
One trade followed all the way through. What you pay, what three different landings return, and what decides it.
Financial prediction markets
Money questions end in a number, not a yes or no. What that changes about how the market has to be built.
Prediction market resolution
Who decides what happened, and can they change their mind. The question to ask before you put money in.
