This market resolves to YES if evidence emerges that points to the alleged UnitedHealthCare CEO assassin, Luigi Mangione, being the operator of the https://x.com/mister_shroom Twitter/X account. This market is about whether the mister_shroom account was operated by Luigi Mangione, and will resolve YES or NO on this regardless as to whether Mr. Mangione is convicted of the assassination.

I have left the criteria to this market purposefully vague because I am not sure what evidence might emerge that could link the two. Some examples of linkage that would cause me to resolve the market include:

  • A personal friend or family member of the alleged assassin linking him with the account

  • Messages from the mister_shroom account being leaked that demonstrate the operator of that account to share multiple identifying features of Mr. Mangione, including work or school history, location, personal history, or name

  • Luigi Mangione himself saying "I am mister shroom" in court

The alleged mister_shroom alt is starting to look sus.

They have not been able to post on the mister_shroom bluesky account.

But have made random other replies in the interim:

It's starting to look like this is an attempt by roon to take some of the heat off of tpot, possibly pointing to a larger conspiracy.

So far there is limited evidence linking mister_shrooms to the alleged UnitedHealthCare CEO assassin.

  • mister_shrooms identified his first name as "Luigi": https://x.com/BasedDaedalus/status/1866289118617194532

  • While active on X, mister_shrooms expressed interest in several of the same topics as the alleged UnitedHealthCare CEO assassin, such as psychedelics, AI, and a generally abrasive attitude similar to the other public writing.

  • Finally, most damning, in the leaked mugshot picture, a mouse cursor is overlaid onto the image in the same place as an earring, similar to a previous mister_shrooms pfp (see attached).

Looks like an easy NO, but the creator is taking YES positions and the market has vague resolution criteria.

Eff that, man.

@DanHomerick I'm not going to rug the market. I just think it's underpriced at present.

bought Ṁ100 NO

This market should resolve NO, the shooter’s Twitter account is https://x.com/PepMangione

@KimberlyWilberLIgt alts do exist lol

@raizel Now I’m very curious to learn what made this Twitter account, with 1 following, 0 followers, and 0 posts in the last seven years, stand out to the market creator

@KimberlyWilberLIgt I apologize, the correct account is https://x.com/mister_shroom.
