President Donald Trump has again predicted that a US-Iran nuclear deal is imminent, stating an agreement could be signed within two to three days. This marks at least the 38th time Trump has made such a prediction since March 23. The repeated assurances come despite the original ceasefire announced on April 7, which was intended to allow two weeks for finalization, having passed without an agreement.
Prediction markets indicate significant skepticism regarding the timeline. Traders on Polymarket place the probability of a US-Iran nuclear deal by June 30 at approximately 22%, while the likelihood of a deal by July 31 sits at roughly 36%. A separate market for a permanent peace deal by June 30 has drifted into the low 20s following reports that Iran suspended talks after Israeli operations in Lebanon.
The potential resolution of the conflict carries high stakes for global oil markets. The Strait of Hormuz, which facilitates the transport of about a fifth of seaborne oil, has been effectively closed since late February. Brent crude recently traded around $86 a barrel, a decline from above $110 in mid-May when ceasefire optimism was higher.
Market Impact
The uncertainty has created significant volatility in oil-linked assets. Executives at Exxon Mobil Corp and Chevron Corp have warned that global inventories may be running dangerously low. The United States Oil Fund LP has roughly doubled year-to-date, becoming one of 2026's most consequential commodity trades. A confirmed reopening of the Strait would likely pressure these positions, whereas a collapse in talks could provide relief.
Probability Metrics

| US-Iran Nuclear Deal | ~36% | By July 31 |
| Permanent Peace Deal | Low 20s | By June 30 |
Trump acknowledged the friction in the negotiations during an interview with Axios, blaming a "side scuffle" between Israel and Iran for jeopardizing the deal. Despite conceding on May 18 that past predictions had not materialized, he maintained that the current situation is different.
How will a potential reopening of the Strait of Hormuz impact global oil prices and inventories if a deal is reached?
What are the implications for oil-linked assets like the United States Oil Fund LP if negotiations collapse?
