Highest temperature in Toronto on December 17?

This is a market about the variation of consumer prices over the 12-month period ending December 2025 in Canada, before seasonal adjustment, as reported by Statistics Canada.

This market will resolve according to the number the Consumer Price Index (CPI) increased by over the 12-month period ending December 2025 (% change) according to the monthly Statistics Canada report.

The resolution source for this market will be the Statistics Canada Consumer Price Index monthly report released for December 2025 (https://www.statcan.gc.ca/en/start), currently scheduled to be released on January 19, 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 this report by clicking on the “Consumer Price Index” option under the "Key Indicators" heading on the home page of https://www.statcan.gc.ca/en/start and selecting "Table 1". The relevant figure can be found under the "% change" column for the relevant month and year compared to the same month of the previous year.

Thus, this is the level of precision that will be used when resolving the market. For the full release schedule, see: https://www150.statcan.gc.ca/n1/dai-quo/cal1-eng.htm?sk=3665

Will Canada's annual inflation increase by 2.3% in December?

If no information for 2026 is provided by NASA by March 1, 2027, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.

Will 2026 be the second-hottest year on record?

This market will resolve to “Yes”, if either of the following conditions are met:

1.  The C.D. Howe Institute’s Business Cycle Council publicly announces that a recession has occurred in Canada, at any point in 2025, with the announcement made by December 31, 2025, 11:59 PM ET.

2.  The seasonally adjusted annualized percent change in quarterly Canadian Real GDP (expenditure-based), chained (2017) dollars GDP from the previous quarter is less than 0.0 for two consecutive quarters between Q4 2024 and Q4 2025 (inclusive), as reported by Statistics Canada (StatCan).

Otherwise, this market will resolve to "No".

Note that any two consecutive, concurrent vintages indicating negative GDP growth will qualify, regardless of prior or later revisions. For example, if upon release, the initial estimate for Q2 2025 was negative, and Q1 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes". If on December 31, 2025 the latest estimate for quarterly GDP in Q3 2025 was negative, this market will stay open until Statistics Canada publishes the initial estimate for Q4 2025, at which point it will resolve to "Yes" if Q4 2025 was negative or if the C.D. Howe Institute’s Business Cycle Council declares a recession by then.

The resolution source will be the official announcements from the C.D. Howe Institute’s Business Cycle Council and Statistics Canada’s estimate of seasonally adjusted annualized percent change in quarterly Canadian real GDP from previous quarters as released by Statistics Canada (e.g., as reported in the line “Gross domestic product at market prices” in Table 3 of the quarterly GDP release: https://www150.statcan.gc.ca/n1/daily-quotidien/250829/t003a-eng.htm)

This market will resolve to “Yes” if the Consumer Price Index (CPI) increased by greater than the listed percent over the 12 month period ending with any month in 2026 according to the monthly Bureau of Labor Statistics (BLS) reports. Otherwise, this market will resolve to "No".

The resolution source for this market will be the BLS Consumer Price Index reports released for each month of 2026 (https://www.bls.gov/bls/news-release/cpi.htm). Resolution of this market will take place upon release of the aforementioned data.

This market may not resolve to "No" until the December 2026 report is issued. Once the December 2026 report is issued, any revisions to previously released CPI figures will not be counted toward this market's resolution. If the CPI report for December 2026 is not issued by January 31, 2027, 11:59 PM ET, this market will resolve based on CPI figures which have already been made available by the BLS.

Note: the resolution source for this market will be the official monthly BLS CPI news release which reports inflation over 12 month periods to only one decimal point (e.g. 2.9%). Thus, this is the level of precision that will be used when resolving the market.

Will inflation reach more than 3% in 2026?

This market will resolve to “Yes”, if either of the following conditions are met:

1.  The C.D. Howe Institute’s Business Cycle Council publicly announces that a recession has occurred in Canada, at any point before 2027, with the announcement made by December 31, 2026, 11:59 PM ET.

2.  The seasonally adjusted annualized percent change in quarterly Canadian Real GDP (expenditure-based), chained (2017) dollars GDP from the previous quarter is less than 0.0 for two consecutive quarters between Q4 2025 and Q4 2026 (inclusive), as reported by Statistics Canada (StatCan).

Otherwise, this market will resolve to "No".

Note that any two consecutive, concurrent vintages indicating negative GDP growth will qualify, regardless of prior or later revisions.
