The U.S.-Iran prediction markets are as volatile as Donald Trump's mood: one minute, the chance of a ceasefire is good, the next the POTUS is calling the Iranians "cuckoo". Your job is to sail the narrow strait and emerge the other side in profit.
In theory, there is a "memorandum of understanding" between the two sides. In reality, the plan looks dead in the water.
On Monday, the U.S. widened its sanctions on Iran, threatening any country with isolation who did deals with Iran.
That was a clear swipe at China, Iran's largest oil buyer, who attacked the "illegal sanctions".
Supposedly, some oil is quietly navigating the Strait of Hormuz, although Iran is keen to stop it. Now, Kalshi has introduced a new shipping lane for trade traffic: normalization before January 1, 2028. This long-term prospect is attracting the biggest money as traders go long.
But how will that impact things in real life, such as the all-important Strait of Hormuz traffic returning to normal? And what else are the prediction markets telling us about long-term prospects for peace?
Market: Strait of Hormuz Traffic
Traders on Kalshi are now attempting to quantify Donald Trump’s mix of ultimatums and dealmaker instincts in real-time. With a shaky plan and a resolute Iran in his way, we try to help you determine what the latest news really means for the Middle East.
Key Takeaways
- The Strait is the signal: the primary focus of global powers is ensuring the Strait of Hormuz stays open. The recent Oman deal hasn't stopped the U.S. blockade, and the Israelis are furious. Trump’s priority is transactional leverage and a stable oil market.
- Kalshi traders are going long on Strait traffic: Over $40 million has been traded on Strait of Hormuz traffic markets, but the new 'Before Jan 1, 2028' market is helping push the volume past the $40 million mark.
- Don't get locked into the nuclear deal market: Kalshi is clear about what satisfies the criterion of a "new Iran-U.S. nuclear deal". Thus far, the new Memorandum of Understanding won't be good enough it if you're waiting for a 'Yes'.
What Trump's Last Deal Looked Like
The prediction markets are lighting up with cinematic propositions: regime change, air strikes, and the recent "Memorandum of Understanding". Meanwhile, deadlines get missed, prediction markets resolve, and the war keeps on truckin'.
Let's take stock on what's was in the latest deal, and importantly, how its contents could impact these volatile prediction markets.
Trump and the Iranian leadership signed a deal at the G7 summit on June 17. These were the main points:
- An end to conflict: "Immediate and permanent" termination of military operations. That includes Lebanon, for which Israel may have a thing or two to say.
- Respect for sovereignty: In English, that means an end to removing regimes. Again, Israel will need persuading that this is a good move.
- 60-day countdown on agreement: Both sides have 60 days to cement the deal by mutual consent. That means more time to gauge the prediction markets as you weight up your options.
- An end to the U.S. naval blockade: Iranian ports will be freed up within 30 days.
- Strait of Hormuz traffic to resume: Iran will "make arrangements using its best efforts" to let commercial vessels pass through the strait. The prediction markets are so far unmoved, despite the summer deal with Oman to open new shipping lanes.
- Reconstruction: The U.S. and Gulf states will provide $300 billion to rebuild damaged infrastructure in Iran. That could effect the U.S. visit prediction markets.
- Nuclear disarmament: Iran must agree never to acquire or develop a nuclear weapon. Key here is that Kalshi does not class this point as a 'Yes' resolve on their "new Iran-US nuclear deal" market.
U.S.-Iran Prediction Markets: A Detailed Look
We highlight some of the most popular U.S.-Iran prediction markets to trade on right now. Make sure you read Kalshi's rules on how these markets resolve. The Memorandum of Understanding (MoU) may not be sufficient to resolve some markets.
Here is how to trade the noise and separate genuine diplomatic agreements from geopolitical hype.

Will the Strait of Hormuz Return to Normal? The Prediction Picks
'Before Jan 1, 2028' | 'Yes' 65¢
Kalshi introduced a new, long-term 'Before January 1, 2028' market this summer. The longer term has helped attract plenty of money.
You can now buy 'Yes' event contracts at Kalshi at 65¢ and give yourself two years to get there.
Cautious traders may see a positive outcome in over two years as the most likely scenario. And in any case, it provides plenty of time for you to swap your contracts if optimism reigns and the price goes up.
'Before Jan 1, 2027' | 'No' 79¢
You'd be sitting pretty had you bought 'No' contracts on any 2026 dates (see below). Who wants to play for more jeopardy and look ahead to 2027?
The probabilities of normalized traffic in the Strait of Hormuz increases as time goes on.
For example, 'Yes Before Jan 1, 2027' is 22%, 'Yes Before Apr 1, 2027' is 45%, and so on. Both prices are down, understandably. By factoring in time for diplomats to do their thing, the odds lengthen.
That's where you can swoop in and buy high-value 'No' contracts. At 45% for April next year, it's an assumption that the regime in Iran and the U.S. adminstration can hammer out a deal. Have you seen anything that suggests that?
❌RESOLVED: 'No' on 'Before September 1, 2026'
Let's start with the big U.S.-Iran market on Kalshi, now worth over $40 million in trade volume.
Anyone going "long" at normalization before September were left disappointed after Trump and Iran started hostilities again.
'Before September 1, 2026' was trading as a 'Yes' at 82¢ back in April. It steadily slalomed downhill as traders got out.
The next 'Yes' deadline is October 1 (3%). Not even the 7% for a November 1 normalization is looking hopeful.
❌RESOLVED: 'No' on 'Before August 15, 2026'
The 'Before Aug 2026' chance of Strait of Hormuz traffic normalizing was trading as high at 69¢ back in June. There was genuine optimism of a truce and a deal.
That was before Trump called the Iranians "mad".
Then, on 17 August, shipping traffic through the Strait of Hormuz ground to a halt. Talks between the U.S. and Iran have stalled, and the ceasefire is coming to an end.
Now, Trump has said that he will declare the Strait a "territory of the United States". No wonder the 'No' on 'Before August 1' was the only play.
❌RESOLVED: 'No' on 'Before July 15, 2026'
We tipped 'No' on 'Before July 1, 2026' at 85¢ last month. Alternatively, you could have moved quickly to get the 64¢ 'No' on 'Before July 15, 2026'.
That tanker has now sailed through the tight Strait, with both markets now out of reach of missiles. Plus, Iran has resumed hitting tankers in the Strait of Hormuz, the U.S. has resumed air strikes, and commercial shipping is in turmoil. Again.
The resumption of commercial traffic in the Strait of Hormuz is what most countries care about the most. It's paramount to the deal, as it both directly and indirectly affects oil prices and other world markets.
In truth, the Strait of Hormuz has been Iran's biggest weapon in this conflict. It's a lot cheaper to shut off shipping than spend money on drones (although Iran has used plenty of those). It's also surprised Trump that Iran has the will, and the geography, to affect world markets in a heartbeat.
However, even if any deal holds, the Strait of Hormuz is now full of mines, despite Trump claiming he's cleared them all. Removing them and making it safe for oil tankers could take months, or even years.
❌RESOLVED: 'No' on 'Before July 1, 2026' (22¢)
Paying 22¢ for the ‘No’ on the 'Before July 1, 2026' was a disciplined play on both the slow, grinding reality of maritime security and the volatility of this conflict. Those were the contracts that stood the best chance.
Yes, there was optimism in the MoU deal, and yes, China and others need that oil. But, as we've seen this month, it doesn't take much for the bombs to start falling again.
For the Strait of Hormuz market to resolve, IMF PortWatch must report a 7-day moving average of transit calls of above 60. It was down to single digits before the weekend's deal.
Let's also factor in new transit fees (Iran and Oman are discussing them, the U.S. opposes them), route diversions, and the "dark ship" phenomenon of vessels disabling ID signals.
All could bring those overall shipping figures down. And that's even if a deal holds long enough.
Market: US-Iran Nuclear Deals
The Pick: 'No' on 'Before Jan 1, 2027' (92¢)
The U.S. and Iran agreed a deal in principal on June 14 to end the war. That sent the prediction markets wild, with prices changing across a range of connected markets.
But we've since seen new strikes, more attrition, and more volatility on the markets.
Curiously, when the Memorandum of Understanding was in place, prediction markets on a nuclear deal fell. The 'Before Jan 1, 2027' 'Yes' price was 60¢ before slumping 13 points after the deal was signed. Market traders clearly didn't believe in Trump's negotiating tactics.
There's more chance of a 'No Before January 2027' trade than ever. The value has gone (it was around 82¢ recently for a 'No') but 79¢ represents a safe trade.
Market: Donald Trump Visiting Iran
The Pick: 'No' on 'Before Jan 1, 2027' (97¢)
Optimism over the MoU deal didn't have much of an impact on this U.S.-Iran prediction market.
While the prospects of a Trump visit to Tehran jumped a little to 8.8% last month, it slipped back down to around 7.5% following the MoU signing.
Then, Trump held that press conference in Turkey. He called talks with Iran a "waste of time," then ordered a wave of strikes on Iranian facilities. Iran countered with hits on U.S. bases in the Gulf.
Never mind the complete lack of trust between the two sides: the Secret Service would have a collective aneurysm before letting the President set foot in a hostile capital governed by the IRGC. This isn't a diplomatic moonshot; it's a security impossibility.
Market: Who Will Visit Iran Before July 2026?
✅RESOLVED: 'No' on 'J.D. Vance Before July' (98.2¢)
We tipped this thin-value play last month at 93%. High-level state visits require months of advance security sweeps, backchannel agreements, and host-nation guarantees.
Iran offers none of the above.
The market priced in some rogue, cinematic diplomatic mission that doesn’t exist in modern statecraft.
Market: Will the US Recognize Reza Pahlavi as Iranian Leader?
The Pick: 'No' (93¢)
Beltway hawks love the exiled Crown Prince, and regime-change chatter always spikes during Middle East escalations.
But formal recognition is a massive, legally binding diplomatic leap. Trump’s foreign policy is highly transactional; he wants leverage, not the headache of recognizing a government-in-exile that holds zero physical territory.
Plus, there are still painful memories of the Shah for many Iranians. His regime was no love-in, despite the brutality of the Ayatollahs since.
Acknowledging Pahlavi functionally severs any remaining backchannels with the actual ruling clerics, complicating every other regional objective, from energy markets to hostage negotiations.
We tipped this market at 11% last month, and it's continued its downward trajectory. At a 6% chance, you can still get in. Bettors are confusing DC think-tank wishcasting with actual State Department mechanics. Fade the fantasy.
Market: Will Reza Pahlavi Visit Iran This Year?
The Pick: 'No' (94.2¢)
If the exiled heir to the Iranian throne steps off a plane in Tehran tomorrow, he is immediately arrested. To bet 'Yes' here at 6.5% is to bet on the total, systemic collapse of the Islamic Republic before the calendar flips.
The Iranian regime is built better than that, something Trump adminsitration is finding out the hard way.
Autocracies with heavily armed, loyalist paramilitaries rarely disintegrate on a neat fiscal schedule.
The diaspora narrative constantly overestimates the speed of revolution. Pahlavi won't risk his life on a symbolic trip without absolute certainty that the IRGC is dismantled. That isn’t happening in the next eight months.
Market: Will the US Reopen its Embassy in Iran?
The Pick: 'No' 'Before 2027' (95.3¢)
The U.S.-Iran deal didn't include anything about full diplomatic relations. Baby steps...
There was a short post-deal spike on the U.S. reopening its embassy before 2027, up 2% from 7% to 9%. However, the continued bombings and renewed Trump threats to Iran keep the prices changing.
The 'No' is a no-brainer, if a long-term one. Reopening a shuttered embassy in a hostile nation isn't just about cutting a ribbon.
It requires a negotiated normalization of relations, massive security infrastructure upgrades, and guarantees from a host government that historically turns a blind eye when mobs scale the gates.
Trading US-Iran Prediction Markets on Kalshi
If you are looking to navigate the volatility of geopolitical events, trading the news has become as structured as trading equities. Navigating the US-Iran prediction market successfully starts with understanding the mechanics of the exchange.
Unlike traditional commodity futures where traders speculate on the price of oil, or traditional betting markets burdened by "juice," Kalshi operates as a regulated exchange for direct event contracts.
Prediction markets allow you to take a financial position on the outcome of specific US-Iran geopolitical events.
The Binary Proposition
In the market for US-Iran developments, the propositions are strictly binary.
You are trading on questions like: "Will the US and Iran sign a new diplomatic agreement by year-end?" or "Will specific military escalations occur before Q3?"
Price as Probability
In this ecosystem, the price is the percentage. Every contract is priced between 1¢ and 99¢, serving as the market’s collective probability estimate.
If a US-Iran event contract trades at 28¢, the collective "wisdom of the crowd" is signaling a 28% implied probability that the event will occur. Sharp traders look for discrepancies between this price and their own geopolitical intelligence.
The Mechanics of $1.00
At expiration, every contract pays out exactly $1.00 for the winning outcome and $0.00 for the losing outcome.
Your profit is determined by the difference between the $1.00 payout and the price you paid to enter the trade, whether you opted for ‘Yes’ or ‘No’. It is the most direct financial representation of "being right."
Dynamic Sentiment & Peer-to-Peer Structure
Kalshi uses a quote-driven order book on a peer-to-peer exchange, meaning liquidity is provided by other traders. The prices of U.S.-Iran markets move constantly as straits are opened, a tanker is bombed, or Trump explodes.
If a new report indicates a sudden blockade or a breakthrough in diplomatic talks, the contract prices will spike instantly. This ensures the market is determined by real-time supply and demand, allowing you to gauge the immediate effect of breaking news on public sentiment.
The Regulatory Landscape
Where you trade geopolitical odds is determined largely by your jurisdiction, split between the regulated U.S. environment and decentralized global exchanges.
Kalshi is the primary legal path. Regulated by the CFTC, it operates as a federal financial exchange. It is fully compliant in all 50 states and allows for seamless USD deposits via standard bank transfers to trade safely on international developments.
