How a sportsbook and a prediction market price the same position

Each pairing below walks through the two pricing models — fixed odds with the cost built in, versus peer-to-peer contract prices plus a stated fee — and shows a live sample quote from each platform on the same market. We maintain 6 pairings, each matching one sportsbook-style platform with one exchange-style platform. Neither side of a pairing is endorsed; the arithmetic is the content.
