Resolution criteria

• The market resolves to YES if, while Yuri Oganessian is alive, the International Union of Pure and Applied Chemistry (IUPAC) or the IUPAC/IUPAP Joint Working Party (JWP) officially announces the validation and recognition of the discovery of any new chemical element with an atomic number of 119 or greater.

• The official IUPAC announcement of discovery validation (similar to the historical verifications for elements 113, 115, 117, and 118) will serve as the primary source of truth.

• The market resolves to NO if Yuri Oganessian passes away before such an official announcement of validation is publicly released by IUPAC.

• Informal or unverified claims of synthesis, papers published in peer-reviewed journals without joint IUPAC/IUPAP validation, or temporary placeholder systematic names do not suffice to trigger a "YES" resolution. Formal validation from IUPAC/IUPAP is required.

Background

Yuri Oganessian (born April 14, 1933) is a pioneering Armenian-Russian nuclear physicist and the scientific director of the Flerov Laboratory of Nuclear Reactions at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. He has led the discovery of several of the heaviest elements on the periodic table. In 2016, element 118 was formally named "oganesson" (symbol Og) in his honor, making him only the second person in history to have an element named after them during their lifetime.

As of 2026, the seventh row of the periodic table is complete, with oganesson as its heaviest element. Active efforts to synthesize the first elements of the hypothetical eighth period, ununennium (element 119) and unbinilium (element 120), are ongoing at facilities worldwide, including JINR and RIKEN in Japan.

Resolution criteria

This market resolves to YES if, while Yuri Oganessian is alive, the International Union of Pure and Applied Chemistry (IUPAC) or the IUPAC/IUPAP Joint Working Party (JWP) officially announces the validation and recognition of the discovery of any new chemical element with an atomic number of 119 or greater.

The primary source of truth will be official public announcements on the IUPAC website.

The market resolves to NO if Yuri Oganessian passes away before such an official announcement of validation is publicly released by IUPAC.

Notes and Edge Cases:

• Informal claims of synthesis, papers published in peer-reviewed journals without IUPAC/IUPAP validation, or the reservation of temporary placeholder systematic names will not trigger a "YES" resolution.

• Formal joint validation and recognition of the discovery are strictly required.

The seventh row of the periodic table is currently complete, with oganesson as its heaviest element. Active efforts to synthesize the first elements of the eighth period, ununennium (element 119) and unbinilium (element 120), are ongoing at major nuclear physics facilities worldwide. Notably, JINR in Dubna launched dedicated experimental runs targeting elements 119 and 120, while researchers at the RIKEN Nishina Center in Japan have been running long-term beam experiments to achieve the same milestone.
