I'm not yet sure how to confirm or deny that, but my feeling is when something like this happens in Russia, conspiracy should not be ruled out.

Market resolves as YES if there is still only speculation by sources that Prigozhin is alive or has been killed in any a way other than a plane crash by the end of 2023, otherwise NO. If it becomes clear that that market was resolved incorrectly as YES after the end of 2023, it should be re-resolved.

Market close date will not be changed. If at the end of 2023 any of the reputable news sources will be openly disputing Prigozhin's death (or the cause of his death), this market will resolve YES. You may try to convince me that I shouldn't consider the source, for example if you will be able to undermine its credibility. If the market will be resolved NO and after some time Prigoshin is known to have lived before the end of 2023, this question should be re-resolved as NO.

I define reputable news source as any national media of the EU or EEA member state with an addition of the UK to include BBC.

Just to clarify: the question is, of course, about the leader of the Wagner Group, not some other person with the same name.
