Next is Above 335.300 at 95%. The venues list this event, but none of their outcomes are matched yet, so prices are shown separately.

Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. 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 2 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "Core CPI YoY - October 2026". Above 0.0% leads at 96.5%. Next is Above 335.300 at 95%. $1.6M has traded across 56 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 11, 2026.

This is a market about core inflation (excluding food and energy) over the 12-month period ending October 2026, before seasonal adjustment, as reported by the Bureau of Labor Statistics. This market will resolve to the percentage change in the Consumer Price Index for All Urban Consumers excluding food and energy (Core CPI-U) over the 12-month period ending in October 2026 according to the monthly Bureau of Labor Statistics (BLS) report. The resolution source for this market will be the BLS Consumer Price Index report released for October 2026 (https://www.bls.gov/bls/news-release/cpi.htm), currently scheduled to be released on November 10, 2026, at 8:30 AM ET. Resolution of this market will take place upon release of the aforementioned data. Note: the resolution source for this market will be the official monthly BLS CPI news release, which reports core inflation (all items less food and energy) over 12-month periods to only one decimal point (e.g., 2.8%). Thus, this is the level of precision that will be used when resolving the market. For the avoidance of doubt, this market resolves on the core CPI figure (the all items index excluding food and energy), not the headline all items CPI figure. If the BLS does not release the relevant figures on the scheduled date, this market may remain open up until the scheduled release time of the next CPI report (https://www.bls.gov/schedule). 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.
