Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue. Ages are as of when this page was built.

About this market

Live prediction market odds for "ISM Services PMI - October 2026". 53.0 to 53.9 leads at 29.7%. Next is 54.0 to 54.9 at 26.1%. $19K has traded across 10 outcomes on Polymarket. The market is expected to resolve by Nov 4, 2026.

This is a market about the ISM Services Purchasing Managers' Index (PMI) for October 2026, as reported by the Institute for Supply Management (ISM). A reading above 50 indicates expansion in the services sector relative to the previous month; a reading below 50 indicates contraction. This market will resolve to the bracket containing the ISM Services PMI for October 2026 according to the monthly ISM Services PMI Report On Business. The resolution source for this market will be the ISM Services PMI Report On Business released for October 2026 (https://www.ismworld.org/supply-management-news-and-reports/reports/ism-report-on-business/), currently scheduled to be released on November 4, 2026, at 10:00 AM ET. Resolution of this market will take place upon release of the aforementioned data. Note: although ISM describes the PMI reading using the term "percent" in its official release (e.g., "The Services PMI registered 53.6 percent"), the PMI is a diffusion index, not a true percentage. For the purposes of this market, the PMI reading will be treated as a plain numerical value, consistent with how the index is universally quoted in financial markets. Note: The ISM Services PMI is reported to one decimal point. Thus, this is the level of precision that will be used when resolving this market. If ISM does not release the relevant figures on the scheduled date, this market may remain open until the scheduled release time of the next ISM Services PMI report (https://www.ismworld.org/supply-management-news-and-reports/reports/rob-report-calendar/). If the information is not released by that time, this market will resolve according to the figures of the most recent previous month with available data.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
