The report was published in Nature on March 8th, 2023:

Dasenbrock-Gammon, N., Snider, E., McBride, R. 

 Evidence of near-ambient superconductivity in a N-doped lutetium hydride. 

https://doi.org/10.1038/s41586-023-05742-0

This will resolve to yes if an independent replication is published in a reputable scientific journal before 01/01/2025.

06/29/2023 - Clarification on the Meaning of Replication:

I will resolve this market yes if the publication demonstrates superconductivity up to similar standards as in Dasenbrock-Gammon et al., including the Meissner effect.

I will not require an independent synthesis.

The publication can use a sample obtained from the Dias Lab. However, the authors must verify that the sample composition is more or less consistent with what is reported in Dasenbrock-Gammon et al.

I apologize for the initial confusion on these issues. Lesson learned.
