News linked to both this project and an event.
Odaily News The prediction market platform Polymarket issued a "resolution clarification" that overturned a market result that had already appeared to be settled. This led to a 20-year-old student's $35,000 bet being declared invalid, while a total of approximately $3.8 million in positions across 1,838 accounts on the platform were liquidated.This clarification clause was written into the platform's rulebook, allowing for retroactive interpretative corrections to market settlement results, thereby altering the final payout. The incident has sparked strong dissatisfaction among traders, who argue that this "post-hoc ruling" mechanism undermines the certainty of market rules, and has ignited widespread controversy within the Polymarket and Kalshi communities.According to user disclosures, the incident originates from a case made public on June 13, where a market result that had ostensibly been settled was later reversed due to a change in rule interpretation.Industry analysts believe that this type of mechanism introduces "settlement clarification risk" into prediction markets, which is a type of tail risk event that cannot be hedged. If such operations occur frequently, they could drive high-risk liquidity away from the current platform towards trading venues regulated by the CFTC or those with formal arbitration mechanisms.Furthermore, this event is seen as one in a recent series of controversies, including settlement disputes surrounding the UMA oracle and Strategy's Bitcoin-related markets, which continue to test market participants' trust in the "finality" of prediction markets.

According to The Block, Strategy disclosed in an SEC filing that it sold 32 BTC between May 26 and May 31, generating approximately $2.5 million in proceeds to pay dividends on its preferred stock. This marks the company’s first Bitcoin sale since December 2022. The disclosure sparked controversy in a Polymarket prediction market—valued at over $20 million in trading volume—that had asked whether Strategy would sell Bitcoin before May 31. The dispute centers on whether the sale qualifies: “Yes” proponents argue the sale occurred before the deadline; “No” proponents contend the information was not publicly disclosed before the market closed and therefore should not count. The market has now entered its final review phase. Polymarket added that “results confirmed outside the deadline will not be recognized,” leaning toward the “No” side. If the dispute escalates further, UMA token holders will vote to resolve it—but prior reports indicate UMA voting power is highly concentrated, with over 60% of active voters linked to Polymarket accounts, raising concerns about impartiality.
Polymarket staff member Shantikiran Chanal posted on platform X, stating that they have taken note of the security reports related to reward distribution, and that user funds and market settlements remain safe. The investigation indicates that a private key leak occurred in a wallet used for internal operations, and the issue is not related to contracts or core infrastructure. Further updates will be provided.Previous report: ZachXBT stated that the Polymarket UMA CTF Adapter contract allegedly came under attack on Polygon, with over $520,000 having been drained.
