This market tracks whether the UK's year-over-year inflation rate will fall within the 2.5% to 2.9% range during 2026. On Polymarket, this outcome currently stands at 74.0%. Resolution will be determined by the Consumer Price Index figure reported by the Office for National Statistics in their monthly inflation bulletin. Watch for the ONS Consumer Price Index release scheduled for January 20, 2027, which will report the 12-month inflation rate ending December 2026 and settle this market.
This is a market about the variation of consumer prices in the U.K. over the 12-month period ending December 2026, before seasonal adjustment, as reported by the Office for National Statistics (ONS). This market will resolve according to the percentage change in the Consumer Price Index (CPI) over the 12-month period ending December 2026, according to the monthly ONS report. The resolution source for this market will be the ONS Consumer Price Index monthly report released for December 2026 (https://www.ons.gov.uk/economy/inflationandpriceindices/bulletins/consumerpriceinflation/previousreleases), currently scheduled to be released on January 20, 2027. 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 this report by choosing the report for the relevant month from the previous releases page for price indices on the ONS website (https://www.ons.gov.uk/economy/inflationandpriceindices/bulletins/consumerpriceinflation/previousreleases). The relevant figure can be found in the "Consumer price inflation rates" table under the column labeled "CPI 12-month rate (%)" for the relevant month. Note: the resolution source for this market will be the official monthly ONS CPI news release which reports inflation change over 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.ons.gov.uk/releasecalendar
Prediction market odds on Polymarket currently reflect 23.1% probability for UK inflation reaching 4.5% or higher in 2026. This contrasts with traditional analyst forecasts, which typically range between 2% and 3.5% based on Bank of England guidance and consensus economic models. The gap suggests traders are pricing in greater upside inflation risk than mainstream economists currently project. Comparing market-implied probabilities to analyst consensus helps identify where sentiment diverges from institutional forecasts.

The U.K. Annual Inflation 2026 market resolves on Jan 20, 2027. Resolution is determined by official UK inflation data for the 2026 calendar year, typically published by the Office for National Statistics. The outcome hinges on whether the annual inflation rate meets or exceeds 4.5%. Traders should monitor ONS releases and Bank of England communications throughout 2026, as these will directly influence final settlement. The market closes at the specified end date, after which no further trading occurs.
Key catalysts for UK inflation include Bank of England interest rate decisions, which directly influence borrowing costs and demand. Energy and commodity price shocks affect input costs across the economy. Wage growth data signals domestic inflation pressure, while sterling exchange rates impact import prices. Fiscal policy announcements—tax changes, spending plans—can stimulate or cool demand. Supply chain disruptions or geopolitical events may drive goods inflation. Monthly CPI releases throughout 2026 will provide real-time signals, allowing traders to adjust positions as the year unfolds and the 4.5% threshold becomes clearer.
