A few hours later, at 7pm, Polymarket created a new prediction market.<br>Epstein suicide note released by...? [May 8, May 31]<br>This market will resolve to “Yes” if any message or note written by Jeffrey Epstein, intended as a suicide note, is made publicly available by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”.<br>A qualifying note must be credibly reported to have been written by Jeffrey Epstein and have been intended to be a suicide note, final message, or equivalent communication.

The intent of this market is clear: the New York Times announced the existence of a purported suicide note and their efforts to have it released to the public, predict when (if ever) it will be released.<br>A week later, on May 6th, The New York Times announced the release of the note.<br>A federal judge has released a suicide note purportedly written by Jeffrey Epstein that was sealed for years as part of the criminal case of his cellmate.

Note released. May 6th is before May 8th. Prediction true. Congratulations to the winners, commiserations to the losers.<br>How does Polymarket decide the truth?

Polymarket lives on the Ethereum blockchain. The New York Times is not on the blockchain. The Federal District Court in White Plains, N.Y. is not on the blockchain. Polymarket bridges the real world and the blockchain with “a decentralized truth machine”, UMA.<br>UMA’ s optimistic oracle (OO) can record any verifiable truth or data onto a blockchain. […] The OO can validate natural-language statements and answer questions about real-world events. This includes arbitrary questions about weather, sports, elections, markets or anything universally verifiable. […] Tokenholders vote on disputes and earn rewards.<br>— UMA

On May 8th the UMA tokenholders were asked to vote on the question “Epstein suicide note released by May 8th?”. Voters read the rules. Votes rolled in. Yes. Yes. Yes. Yes. Yes. Yes. The overwhelming consensus of the decentralized truth machine is Yes, the Epstein suicide note was released by May 8th.<br>You Can’t Handle the Truth!

As a Polymarket bettor, you bet according to the rules. As an UMA voter, you vote according to the rules. But these rules aren’t the same. Voters receive the rules as the bettors did, plus unbounded additional information.<br>Updates made by the question creator via the bulletin board at […] as described by […] should be considered.

Following the decentralized truth machine’s determination that Yes, the Epstein suicide note was released by May 8th, Polymarket issued an update to the question:<br>Articles cited to prove the validity of the note within this market’s timeframe (Handwriting on newly released note matches one found after Epstein’s death, experts tell AP, Compare the Purported Epstein Suicide Note to His Writings) continue to stress that they have not directly authenticated the May 6 note.

The update introduced a new rule, “directly authenticated”. Prediction market bettors did not bet on a “directly authenticated” note. Millions of dollars of volume flowed through the market without any mention of a “directly authenticated” note.<br>On May 12th, Polymarket triggered another vote, the final vote. Unknown to market participants, voters are instructed that “they have not directly authenticated the May 6 note”. The votes roll in.<br>No...
