Note: this market is not referring to the material known as LK-99, claimed to be a room-temperature, ambient pressure superconductor, discovered by a South Korean group. This is an entirely separate claim.

Taj Quantum claim to have invented a room temperature, ambient pressure superconductor.

On July 25th, 2023, they were granted a patent 17/249,094 | 545074945NP:ABOVE ROOM TEMPERATURE TYPE II SUPERCONDUCTOR

The inventors are listed as John A. Wood, Bethlehem, PENNSYLVANIA (US) and

Paul J. Lilly, Howey In The Hills, FLORIDA (US)

They've tweeted about it here:

Wherein they clarify that they are indeed claiming it to be superconducting at ambient pressure as well as room temperature (the patent does not emphasise the ambient-pressure part).

Edit: and they have made a press release:

Did they invent such a superconductor?

This market resolves YES or NO on credible reports of convincing empirical tests establishing that the material as described in this patent either does or does not exhibit superconductivity at room temperature and ambient pressure.

Ideally this will take the form of peer-reviewed scientific publications that establish a consensus view, but other convincing evidence will suffice if it is to a high standard. I will not resolve immediately upon early evidence, but wait (possibly a substantial time) for a consensus view to emerge among superconductivity researchers, in case early attempts are flawed or controversial.

Alternately the market resolves NO immediately if the inventors retract their claim that the material is a superconductor.

The market resolves NO at the beginning of 2030 if there has been no evidence either way, or the close date will be extended if there is some evidence that is the subject ongoing debate at that time.

It does not matter whether other claims made about the material are true - for example whether it is specifically a type II superconductor (as claimed), or not. It only matters to this market whether the material exhibits superconductivity at room temperature and pressure.
