Market Description
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 1 megaton (1000 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.

Reason
No override, sports marker, rule, or upstream hint matched. Market is unclassified — the keyword rules need an entry for this topic.
Categories come from a deterministic engine: manual overrides (highest priority) → sports hard markers → event-tag rules → keyword rules → Gamma category hint → default. The engine is versioned in category-overrides.ts; methodology lives at /methodology.
