“54 cents.” “$0.54.” “54 percent.” On a Yes/No share they are one price. They are not three markets, and they are not a poll.
We lead with cents because that’s what you pay. The percent is a translation. Useful — and how people start treating a price like a forecast.
Three spellings, one share
54¢ is how we write it on the state and platform pages. $0.54 is the same share in dollars. 54% is the translation people make when they ignore the spread and the fee. Useful. Also how a price starts pretending to be a forecast.
Sportsbook juice is a different language. We won’t write “54¢ = −117.” Come back to cents before you compare venues.
Why we refuse the percent-as-forecast move
An implied probability assumes a mid-market price, a tight spread, and a contract that will actually pay $1.00 or $0.00 on a clear rule. Retail books are not always tight. Fees come out of the difference between your entry and $1.00. Resolution text can surprise you. None of that belongs in a clean “the market says 54%” sentence from an editorial site.
We also do not know your fill. A screenshot of 54¢ is not a promise you can buy there. Polymarket’s crypto-collateral book, Kalshi’s USD exchange, and a sports-branded prediction vertical can price similar cents on differently worded questions.
How to read a sample quote on this site
When a market guide shows 42¢ on a Fed-threshold example, read it as $0.42 per illustrative share. The 42% in your head is allowed. The claim “PredictionMarketsUSA.com forecasts 42%” is not. Sample contracts are teaching props. They are not live, not sized, and not a recommendation.
