5kt meteor strike in 2026?

Resolution Criteria

This market will resolve to "Yes" if a natural meteoroid (bolide) explodes in Earth's atmosphere with a total impact energy greater than or equal to 5 kilotons of TNT equivalent between January 1 and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. 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.

A 5-kiloton or greater meteor strike in 2026 is the subject of this prediction market, which tracks whether a natural bolide will detonate in Earth's atmosphere with that energy threshold during the calendar year. Market volume is concentrated on the 'No' outcome, making a qualifying event the minority position. Resolution is drawn from the NASA JPL Fireball and Bolide Data repository, with a deadline of 31 December 2026.

Market structure

This is a binary yes/no market with a single qualifying threshold: a natural meteoroid producing at least 5 kilotons of TNT-equivalent impact energy between 1 January and 31 December 2026. Volume is skewed toward 'No'. Resolution relies primarily on the NASA JPL Fireball and Bolide Data repository. If that source is unavailable or not updated by 28 February 2027, a consensus of ESA, IAWN, U.S. Department of Defense data, or credible scientific reporting may be used.

Background

Earth is struck by meteoroids of varying sizes continuously, but events reaching 5 kilotons of TNT-equivalent energy are relatively rare. The most prominent modern benchmark is the Chelyabinsk event of February 2013, which released an estimated 400–500 kilotons of energy and caused widespread damage across the Ural region of Russia. Smaller bolides in the 1–10 kiloton range occur roughly once every few years, though many detonate over oceans or remote areas and attract little public attention. The NASA JPL Fireball and Bolide Data repository maintains a continuous record of atmospheric impact events detected by U.S. government sensors, providing the authoritative dataset for markets of this type. Growing global sensor networks have improved detection rates, meaning qualifying events are less likely to go unrecorded than in previous decades.

Key factors

The primary variable is the stochastic nature of meteoroid impacts: no forecasting model can predict whether a qualifying event will occur in a given calendar year, as the distribution of such strikes follows historical frequency patterns rather than a predictable schedule. The 5-kiloton threshold is the key structural dependency — events just below it do not qualify regardless of other characteristics. Detection completeness is also relevant; an event over a remote ocean region or at high altitude may be captured by satellite or infrasound sensors but could face delays in appearing in the NASA JPL dataset, potentially affecting resolution timing. The fallback resolution mechanism — consensus from ESA, IAWN, and DoD sources — provides a contingency if data publication lags. Artificial reentry events, including spacecraft or rocket body deorbits, are explicitly excluded, so ambiguous cases may require classification by scientific authorities before resolution can be confirmed.
