Resolution criteria

This market resolves to "YES" if a new fish species is formally described and accepted by the scientific community (e.g., published in a peer-reviewed taxonomic journal or indexed in the World Register of Marine Species) before the market's closing date. Otherwise, it resolves to "NO."

"New species" refers to a species that was previously unknown to science and is distinct from existing described species. Evidence of acceptance includes listing in authoritative databases such as the World Register of Marine Species (WoRMS) or FishBase.

Background

The discovery of new fish species is a continuous process, with hundreds of new species described annually by ichthyologists worldwide. Discoveries often occur in underexplored environments, such as the deep sea, remote river systems, or through the re-examination of existing museum specimens using modern genetic analysis. Because taxonomic classification requires formal peer-reviewed publication, there is often a time lag between the initial collection of a specimen and its official recognition as a new species.
