U.S.-Iran Preliminary Deal to End Gulf War Sends “Iranian Regime Fall Before 2027” Odds Lower on Polymarket

A reported preliminary U.S.-Iran agreement to end the war in the Gulf helped drive a broad risk-on move across global markets, easing immediate fears of regional escalation. On Polymarket, the contract “Will the Iranian regime fall before 2027?” was priced at 9.5% Yes on the latest update, down from 10.5%.

Key Takeaways

Polymarket prices a 90.5% chance the Iranian regime does not fall before 2027 (Yes 9.5%, No 90.5%).
The odds eased after reports of a preliminary U.S.-Iran deal to end the Gulf war, which pushed stocks and bonds higher while oil fell.
The market resolves on Dec. 31, 2026, and the contract has traded about $20.3 million in volume.

Global stocks and bond prices rallied while oil slid to a three-month low after U.S. President Donald Trump said a preliminary agreement to end the war in the Gulf had already been signed by the United States and Iran. The Dow and the STOXX 600 both hit record-high closes, as investors saw the deal as reducing inflation pressure and lowering the risk of higher interest rates. The agreement was expected to reopen the blockaded Strait of Hormuz and extend a 60-day ceasefire while negotiators address issues including the future of Iran’s nuclear program. Brent crude settled down $4.16, or 4.76%, at $83.17 a barrel, while U.S. WTI fell $4.13, or 4.87%, to $80.75. U.S. Treasury prices rose and the 10-year yield touched its lowest level since May 12 amid expectations that lower energy costs could cool inflation risks.

Polymarket Pricing: Yes 9.5% vs No 90.5% With $20.3M Volume on Iran Regime Change Contract

On Polymarket, “Will the Iranian regime fall before 2027?” traded at 9.5% Yes versus 90.5% No, with No the clear leading outcome.

Cumulative volume stood at $20,322,478, signaling deep interest despite the low implied probability.

Traders will watch for publication of the deal’s terms, any confirmation tied to the Strait of Hormuz reopening, and whether the ceasefire holds through the stated 60-day window as the contract approaches its 2026-12-31 resolution.
