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, the oldest 1 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "October Inflation China - Annual". 0.9% to 1.0% leads at 42.5%. Next is 0.7% to 0.8% at 40.9%. $21K has traded across 5 outcomes on Polymarket. The market is expected to resolve by Nov 9, 2026.

This is a market about the variation of consumer prices in China over a 12-month period ending October 2026 as reported by the National Bureau of Statistics (NBS) of China. This market will resolve according to the number the Consumer Price Index (CPI) increased by during the 12-month period ending October 2026 (% change from the same month in the previous year) according to the monthly NBS report. The resolution source for this market will be the NBS Consumer Price Index monthly report released for October 2026 (https://www.stats.gov.cn/english/PressRelease/), currently scheduled to be released in November 2026. Resolution of this market will take place upon release of the aforementioned data. If no data for the specified month is released by the date the next month's data is scheduled to be released, this market will resolve based on data from the last available month. You can find the relevant figure by locating the report for October 2026 on the Press Releases page (see: https://www.stats.gov.cn/english/PressRelease/), locating the table named "Consumer Price Index in October 2026", and finding the consumer price index figure in the column labeled "Growth Rate Y/Y (%)". Note: the resolution source for this market will be the official monthly NBS CPI news release which reports inflation during 12-month periods to only one decimal point (e.g. 1.9%). Thus, this is the level of precision that will be used when resolving the market. For the full release schedule, see: https://www.stats.gov.cn/english/PressRelease/ReleaseCalendar/

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.
