# How high will inflation get in 2026? The decisive word is greater. A reading exactly at a strike does not satisfy this CPI contract, even though a casual headline might say inflation reached that level.

A reading exactly at a strike does not satisfy this CPI contract, even though a casual headline might say inflation reached that level. At the October 4, 2026 market snapshot, Above 4.5% carried a 12.5% Yes price. Other open contracts included Above 5% at 8%; Above 6% at 3.85%.

The rate must exceed the listed threshold, rather than merely equal it. [1](https://polymarket.com/event/how-high-will-inflation-get-in-2026) No waits for the December 2026 CPI release; if absent January 31, 2027 at 11:59 p.m. ET, use available reports. Revisions after the December release do not count. [1](https://polymarket.com/event/how-high-will-inflation-get-in-2026) ## Evidence for and against the leading outcome A renewed increase in the twelve-month headline measure beyond the strike supports Yes. Cooling current prices or favorable base effects can prevent the annual rate crossing, even when the price level remains high. The next useful checks are headline CPI rather than core or PCE; strict greater-than boundary; december report and revision cutoff. The linked primary references make the process and named data source inspectable.

Their Yes prices should not be added into a single winner probability, and the highest Yes price is not automatically the most informative question. The event had approximately $1,480,299 in total traded volume at observation. That is a record of turnover across this event, not a count of distinct people, a search-volume estimate or proof that every child contract is easy to trade. The analytical quote is fixed to the timestamp shown here; later live prices can differ.

Source: [Polymarket — event, child contracts and resolution rules](https://polymarket.com/event/how-high-will-inflation-get-in-2026) ## Weighing the outcome ### Outcome in focus Above 4.5% — Yes ### Supporting case A renewed increase in the twelve-month headline measure beyond the strike supports Yes. ### Challenging case Cooling current prices or favorable base effects can prevent the annual rate crossing, even when the price level remains high. ### What to watch - Headline CPI rather than core or PCE - Strict greater-than boundary - December report and revision cutoff ### What may already be priced in The analysis starts from 12.5% for the Yes side of “Above 4.5%”. A view merely agreeing that this is plausible does not show that the price understates it. The probability, rule and remaining time all have to be compared.

No. 12.5% is the observed Yes price for “Above 4.5%”, not a verified probability from independent research. A useful assessment needs evidence that changes the expected chance under the exact rules, plus the actual price available at the time.
