This market will resolve based on the data for the Global Land-Ocean Temperature Index for December 2025 versus the data points available for all other Decembers on record.

Note: If December 2025 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with.

The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Dec" (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 December 2025 is provided by NASA by January 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this 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. If this dataset has not been updated to include all relevant dates by February 28, 2027, 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.

1 megaton meteor strike in 2026?

This market will resolve to “Yes” if 1 or more earthquakes with a magnitude of 9.0 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”.

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?

For the purposes of this market, a Category 5 hurricane is a hurricane with maximum sustained winds of 157 mph or higher, as described at https://www.nhc.noaa.gov/aboutsshws.php, and a hurricane landfall is said to occur when the hurricane's surface center intersects with the coastline, as described at https://www.nhc.noaa.gov/aboutgloss.shtml#LANDFALL.

Any prior updates will not be considered finalized.

If this dataset has not been updated to include all relevant events by March 31, 2027, or if the Smithsonian GVP becomes permanently unavailable, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.

Note: Smithsonian Institution Global Volcanism Program databases, which include eruptions that reached the relevant threshold prior to this market’s timeframe (e.g., https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2025), will not be considered.

Major volcano eruption (VEI ≥6) in 2026?

This market will resolve according to the number of natural volcanic eruptions with a Volcanic Explosivity Index (VEI) of 4 or higher between January 1 and December 31, 2026, 11:59 PM ET.

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%).
