Resolution criteria
This market resolves to YES if, before January 1, 2028, there is a confirmed and widely accepted scientific discovery identifying the physical nature or specific constituent of dark matter.
For a "YES" resolution, the discovery must satisfy both of the following:
Scientific Publication: A peer-reviewed paper is published in a major scientific journal (such as Nature, Science, or Physical Review Letters) announcing the direct detection or identification of a specific dark matter candidate (e.g., WIMPs, axions, sterile neutrinos, or primordial black holes) with a statistical significance of at least 5 sigma (five standard deviations).
Official Endorsement: The discovery is officially acknowledged or formally endorsed as a confirmed detection of dark matter by a leading international scientific body or research institution (e.g., CERN, NASA, ESA, or the American Physical Society).
If there is no peer-reviewed, 5 sigma significant confirmation of the identity of dark matter officially endorsed by December 31, 2026, the market resolves to NO.
Ongoing scientific debates, unconfirmed candidate signals, or discoveries that only narrow down constraints without definitively identifying the dark matter source will resolve the market to NO.
Background
While the gravitational effects of dark matter have been observed for nearly a century, its exact nature remains one of physics' greatest mysteries. Researchers continue to search for direct evidence using deep underground detectors and advanced space observatories.
In September 2026, scientists operating the LUX-ZEPLIN (LZ) experiment in South Dakota announced a single unexplained particle interaction that matches some theoretical dark matter models. However, at approximately 2.6 sigma significance, the signal remains far below the 5 sigma threshold required to claim an official scientific discovery. This market asks whether a definitive, high-confidence discovery identifying what dark matter is will be achieved and verified before the end of 2026.
