The prediction market platform Polymarket is currently embroiled in one of the largest contract disputes in its history. Following the announcement of an agreement between the US and Iran, whether the related bets exceeding 345 million dollars can be paid out remains controversial.

The US and Iran announced an agreement over the weekend, bringing a certain level of relief to the stock and bond markets. However, the bets on the US-Iran peace agreement on Polymarket have become stalled due to disagreements over the interpretation of terms.

On Sunday night, there was a proposal to determine the related contract as "yes," meaning that the peace agreement had been reached; this was quickly questioned by UMA token holders—UMA is the cryptocurrency used by Polymarket to address contract disputes.

Opponents argue that the contract terms have not been met: on one hand, there are currently no formal documents signed; on the other hand, it remains unclear whether the agreement between the two sides can constitute a "permanent" cessation of hostilities. The final voting on the dispute is expected to be completed within this week.

This dispute is the latest and largest contract controversy that Polymarket has faced recently, reflecting the structural challenges that prediction markets encounter in transforming complex real-world events into binary contract determinations.

The vagueness of the agreement content leads to disagreement on contract determination

On Monday, the US and Iran stated that they had reached a consensus on a temporary agreement to reopen the Strait of Hormuz for 60 days. Delegations from both sides will further discuss the details in Qatar this week, with a memorandum of understanding expected to be formally signed on Friday in Switzerland.

The terms of the contracts related to the Iran peace agreement on Polymarket explicitly state that any agreement must clearly indicate that the US-Iran military conflict "has ended or will cease permanently," while a temporary ceasefire is not within the scope of recognition. The temporary nature of the strait being open for only 60 days led many Polymarket users to believe that the agreement does not meet the "permanent" standard.

However, the other side cited Pakistani Prime Minister Shehbaz Sharif's description of the agreement—as a declaration of "immediate and permanent termination of military actions"—believing this is sufficient to support the determination of the agreement's establishment.

Among these, a contract tracking "whether the peace agreement was reached before Monday" attracted trading volume of up to 66 million dollars, with the dispute particularly concentrated.

The UMA governance mechanism is re-examined

This dispute once again brings Polymarket's reliance on UMA to handle disputed contracts to the center of controversy.

According to the current mechanism, UMA token holders debate online in chat rooms and then vote to decide the contract's direction. Since this process does not require holders to disclose their identities or potential conflicts of interest, some traders have held critical views for a long time.

According to previous analysis by Bloomberg, just nine wallet addresses hold more than half of the tokens used for such voting, and a few holders may have a decisive impact on the outcomes of contracts worth tens of billions of dollars.

It is worth noting that during the UMA dispute resolution period, the related contracts remain open for trading, which means that investors can actually bet on the direction of the dispute itself, rather than just the original event that attracted funding.
