Please note: Kalshi's rules as stated do not require ambient pressure.
Resolves the same as https://kalshi.com/markets/supercon/roomtemp-superconductor
Copy of the summary and some relevant excerpts of the rules:
If an eligible peer-reviewed journal publishes research that reports that a material is room-temperature superconductive (it has a critical temperature greater than room temperature, exhibits 10^-10 ohm-cm electrical resistivity or less, and exhibits the Meissner effect), then the market resolves to Yes.
a peer-reviewed research on superconductivity (excluding research conducted by researchers at the institutions of the authors of the two July 2023 papers on LK-99) reports the discovery of a material that has both a critical temperature (Tc) which exceeds 296 kelvin (73.13 degrees Fahrenheit), electrical resistivity of 10^-10 ohm-centimeters or lower, and which demonstrates the Meissner effect. That material need not be LK-99.
Eligible journals include those in the first quartile ("Q1") of SJR's condensed matter physics journals or any journal above a 1.0 SJR ranking.

As noted elsewhere, this does not specify ambient pressure, so a high pressure SC coming out in time (probably not LK-99) will satisfy this.

@CamillePerrin Yeah, the chances by 2024 still seem pretty low despite that, but it seems like this should be far higher than room-temp ambient-pressure in the same timeframe.
