Polymarket Iran Peace Contract in Dispute: $345 Million in Bets Awaiting Ruling

```

The prediction market platform Polymarket is caught in one of the largest contract disputes in its history. After the US and Iran announced an agreement, more than $345 million in related bets remain controversial as to whether they can be settled.

The US and Iran announced an agreement over the weekend, bringing some relief to stock and bond markets. But on Polymarket, contracts betting on a US-Iran peace agreement are deadlocked due to disagreements over the contract’s wording.

On Sunday night, a proposal was made to settle the related contract as "yes", i.e., that a peace agreement had been reached. This move was quickly questioned by UMA token holders—UMA is the cryptocurrency Polymarket uses to handle contract disputes.

Opponents believe the contract terms have not yet been satisfied: on the one hand, no formal document has been signed; on the other hand, whether the agreement constitutes a "permanent" cessation of hostilities remains unclear. The final vote on the dispute is expected to be completed this week.

This dispute is the latest and also one of the largest contract controversies Polymarket has recently faced, reflecting the structural challenges prediction markets encounter when converting complex real-world events into binary contract decisions.

Unclear Agreement Content, Contract Settlement Divisions

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

The terms of the Polymarket contract related to an Iran peace agreement explicitly require any agreement to state that US-Iran military conflict "has ended or will permanently cease," and temporary ceasefires are not within scope. The temporary nature of the 60-day reopening of the Strait has led several users to believe the agreement does not meet the "permanent" criteria.

However, the other side cites Pakistani Prime Minister Shehbaz Sharif’s description of the agreement—as an "immediate and permanent end to military action"—as sufficient justification for settlement.

Among the contracts, one tracking whether a "peace agreement is reached by Monday" attracted as much as $66 million in trading volume, with disputes especially concentrated here.

UMA Governance Mechanism Scrutinized Again

This dispute once again puts Polymarket’s reliance on UMA to resolve contract controversies under the spotlight.

Under the current mechanism, UMA token holders discuss in online chat rooms and then vote to decide the contract outcome. As this process does not require holders to reveal their identities or potential conflicts of interest, some traders have long criticized it.

According to previous Bloomberg analysis, just nine wallet addresses control more than half the tokens used for such votes, meaning a few holders may decisively affect the outcome of contracts worth billions.

Notably, during UMA dispute resolution, the relevant contracts remain open for trading, meaning investors can actually bet on the direction of the dispute itself, rather than just the original event that attracted funds.
