How to Read Implied Probability on Polymarket (US 2026)

Official Prices & Market Data: every contract is priced between $0 and $1, and that price is the market’s collective belief about how likely the outcome is. Their teaching table: $0.25 is roughly a 25% chance, $0.50 is a coin flip, $0.75 is a 75% chance. Official What is Polymarket US uses the same map — 62¢ means roughly a 62% chance the event occurs. A teaching Yes at 32¢ is that same read: about a 32% implied chance. We do not reprint a live 32¢ ticket.

Official Odds Display: from the home screen, tap the Odds control at the top right and switch between price (¢) and percent chance (%). Their teaching pair is the same market shown two ways — “only the way it’s shown changes.” A 32¢ Yes and a 32% Yes are one reading, not two different odds. If the live ticket prints that Odds control, follow it. If it does not, the action is the same: the cents and the percent are the same figure.

Official US pages we checked say “prices are probabilities,” “collective belief,” “roughly a 25% chance,” and “percent chance.” They do not reprint a retail column header literally labelled “implied probability” on the swipe we checked. We will not invent one. The action is the number on Yes or No, read as a percent. Public international help uses “Implied Probability” as a table header — that is the crypto product’s help, not a US stamp we paste onto the QCEX ticket.

Official Market Settlement and Official Prices & Market Data: a winning contract settles at $1.00 and a losing contract at $0.00. A teaching Yes at 32¢ that does not happen still goes to zero. The 32% figure is how the book was pricing the sentence when you looked — not a floor, not a promise the event occurs 32 times out of 100 on your ticket, and not a sportsbook “win probability” graphic. Official What is Polymarket US teaching fill is a different docs example (55¢ Yes, settle $1.00, +45¢ per contract). We will not mash that P&L onto a 32¢ teaching fill as a live quote.

Official How are Polymarket odds determined?: odds come entirely from user trades. Prices update whenever a buy or sell is matched, and those trades reflect what users believe right now. A 32¢ print you screenshot is history the moment the next match lands. Official What is Polymarket US: unlike a sportsbook, you can sell before the event resolves. That is why a displayed chance is not a locked hold.

Official Prices & Market Data says “roughly a 25% chance.” Official What is Polymarket US says “roughly a 62% chance.” We keep that hedge. We will not write a confidence interval, a calibration chart, or a “true odds” number those US pages do not print. Confirm the live ticket after KYC. We do not reprint it.

Sportsbook moneylines are a house price you take or leave, often written as +150 or −135. Converting those numbers into a percent is a sportsbook juice read. A Polymarket Yes at 0.32 is a traded event-contract price other users posted. Official How are Polymarket odds determined?: Polymarket US does not set prices or take the other side. Official What is Polymarket US: your order matches another user’s order on a central limit order book. Do not convert 32¢ into an American moneyline and treat that conversion as the ticket. We will not publish that table.

Official Odds Display’s menu is price (¢) or percent chance (%). Their teaching pair is WAS 17¢ / KC 86¢, or 17% / 86%. That page does not add an American-odds column. We will not invent a third format those US pages do not print. If you wanted a house moneyline written as plus juice, that is a different product — see prediction markets vs sportsbooks.

A sportsbook implied probability is usually reverse-engineered from a posted American (or decimal) line, and that line already includes house margin. Polymarket US’s published map is simpler: the cents are the chance. Official Prices & Market Data does not print a vig-removal formula. We will not invent one, and we will not “fair up” 32¢ as if it were a minus moneyline. The Yes/No how-to is the tile and the book. This page is only the percent read.

Official Browse Markets: each market shows the question, the Yes and No prices, and a resolution date. Official Place a Trade: tap Yes if you think the printed event happens, or No if you think it does not. The implied chance is the number on that side — not a second game, and not a sportsbook two-way. If the sports desk is hidden where you live, stop.

Official Odds Display names the control Odds, at the top right of the home screen, with two published formats: price (¢) and percent chance (%). If the live US app prints that control, use it. If the live ticket uses a different word — a percent sign on the tile, a ¢ after the number, or no toggle at all — follow that live label. We will not invent a third chip. The read is the same: 32¢ and 32% are one figure.

How to read Yes/No prices is the tile, last versus the book, and why two sides are not always a clean $1. How to read a moneyline is the winner sentence. How to buy your first NFL ticket is the first swipe. How Polymarket fees work is the published cost stack. We link those instead of cloning them. Event contracts can settle at zero. Trade only what you can afford to lose. Nothing here is investment advice.
