Prediction markets sceptical of imminent resolution as Iran-U.S. tensions escalate in Hormuz

Markets reflect growing uncertainty over the Iran-U.S. stand-off in the Strait of Hormuz, with traders adjusting predictions amid escalating military tensions and lingering diplomatic doubts.

Prediction markets are now treating a prolonged stand-off in and around the Strait of Hormuz as less certain than they were only days ago, even as U.S. forces reinforce their presence and Iran continues to signal defiance. On Polymarket, the contract on whether Donald Trump will say the Hormuz blockade has been lifted by 31 May has slipped to 64.5% yes from 72% the previous day, and down sharply from about 90% a week earlier, suggesting traders think the disruption may last longer than first expected.

The shift comes amid a fast-moving military escalation. Reuters-style reporting in Axios said on 23 April that Iran’s Islamic Revolutionary Guard Corps navy had laid additional mines in the strait, while the USS George H.W. Bush carrier strike group arrived in the region and the U.S. Navy began deploying underwater drones for mine-clearing. That followed earlier reports that Iran had объявлено the strait closed on 18 April and fired on tankers transiting the waterway, after Washington’s blockade and repeated warnings to shipping.

The market for a diplomatic breakthrough is moving in the opposite direction. Traders now see only an 11% chance that the Islamabad talks will continue, while the peace-deal contract shows a clear separation between near-term and later-dated outcomes: odds for a deal by 30 April stand at 10.5%, compared with 35.5% for 31 May. That spread implies participants are still looking for a possible catalyst after this month, even if they are sceptical of an immediate agreement.

The price action has also underlined how sensitive the market is to new headlines. The biggest move in the Hormuz contract was a five-point jump at around 3.50pm, when the price rose from 57% to 62%, and the order book depth of about $8,975 means relatively modest trades can still move the market. Total volume on the contract has reached $95,253 in USDC.

For now, the balance of risk appears to rest on whether military pressure intensifies or diplomacy gains any traction. U.S. forces seized an Iranian-flagged vessel in the Gulf of Oman on 19 April after warnings failed, according to Axios, while Military.com reported that a blockade announced on 16 April was designed to force ships away from Iranian ports and reopen the strait. Against that backdrop, traders are pricing a conflict that can still worsen quickly, but may yet leave room for talks if the two sides step back.
