This market will resolve according to the value reported by the Global Land-Ocean Temperature Index for November 2025 when it is released.

An anomaly within a named bracket for November 2025 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for November 2025 is later revised.

The primary resolution source for this market will be the figure found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Nov" in the row "2025" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt).

If NASA’s “Global Temperature Index” is rendered permanently unavailable, other information from NASA may be used.
If no information for November 2025 is provided by NASA by January 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.

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.

The object must be classified as a natural meteoroid; events involving artificial objects or reentry vehicles do not qualify.

The primary resolution source will be the NASA JPL Fireball and Bolide Data repository: https://cneos.jpl.nasa.gov/fireballs/. The relevant field for determining impact energy is the “Impact Energy (kt)” column. If this dataset has not been updated to include all relevant dates by February 28, 2026, or if the NASA JPL Fireball and Bolide Data repository becomes permanently unavailable, this market may resolve based on a consensus of credible sources including the European Space Agency (ESA), the International Asteroid Warning Network (IAWN), the U.S. Department of Defense, or credible reporting of a scientific consensus, such as a NASA press release.

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.

The object must be classified as a natural meteoroid; events involving artificial objects or reentry vehicles do not qualify.

The primary resolution source will be the NASA JPL Fireball and Bolide Data repository: https://cneos.jpl.nasa.gov/fireballs/. The relevant field for determining impact energy is the “Impact Energy (kt)” column.

Major meteor strike (10kt+) in 2025?

This market will resolve to “Yes” if 1 or more earthquakes with a magnitude of 10.0 or higher occur anywhere on Earth between December 8, 2025 12:00 PM ET, and December 31, 2026, 11:59PM ET. Otherwise, this market will resolve to “No”.

If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until January 31, 2027, 11:59 PM ET, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used.

The IPCA (t. Broad National Consumer Price Index) is the official inflation rate measure used by the Brazilian government, tracked by the Brazilian Institute of Geography and Statistics (IBGE). The IPCA reflects the cost of living for households across urban areas in Brazil, measuring changes in prices for a diverse set of goods and services.

This market will resolve to “Yes” if the 12-month IPCA for December 2025 is below 5.50%. Otherwise, this market will resolve to “No”.
