Reading the odds: prices as probabilities
Cents, implied probability and the spread — the three numbers that tell you what a market really thinks.
Outcomer Team · Jun 20, 2026
Every market on Outcomer shows a price in cents. That single number carries more information than it looks like — once you can read it, the whole board becomes easier to scan.
Price is probability
A Yes share at 30¢ implies a 30% chance the event happens. The No side is simply the mirror — it trades near 70¢. If the two do not add up to roughly 100¢, that gap is the spread, the small cushion between the best buy and sell prices.
What moves the number
- News — a result, a poll, an announcement.
- Flow — a large buyer or seller pushing the price toward their view.
- Time — as an event nears, uncertainty collapses toward 0¢ or 100¢.
Watching how fast a price reacts tells you how confident the market is. A number that snaps back after a spike is a market that disagreed with the move.
