Iran Peace Deadline in 72 Hours at 23% -- The Probability Ladder Tells a Different Story

Iran declared the Strait of Hormuz "completely open" Friday. Oil fell. But prediction markets are only pricing a 23% shot at a permanent US-Iran peace deal by Tuesday's April 22 deadline -- and the full probability ladder implies the real resolution runs through May or June, not next week.

Today's Prediction Market Odds


Top Contracts to Watch

1. US x Iran Permanent Peace Deal: 23% April 22 -> 43% April 30 -> 63% May 31 -> 70% June 30
( Polymarket April 22 | Full Ladder)

That 47-point gap between next Tuesday and June 30 is the market saying: deal will happen, just not fast. Gulf and European leaders cited a six-month nuclear deal timeline last week, and the curve reflects exactly that. For crude traders, the base case is continued US naval blockade of Iranian ports through May at minimum. The 77% probability April 22 passes without a deal is the consensus, not a tail risk.

2. Strait of Hormuz Traffic Returns to Normal by April 30 -- 31.5% ($17.9M total volume)
( Polymarket)

Hormuz being "open" and traffic "returning to normal" are not the same thing. Iran opened Hormuz for commercial transit Friday, but the US naval blockade of Iranian ports remains fully in place -- cutting off 90%+ of Iran's seaborne trade. "Normalization" requires the blockade to lift, not just the strait to be clear. At 31.5%, this is the leading indicator to watch: if it starts climbing, second-round talks are gaining real traction.

3. Iranian Regime Fall by April 30 -- 1.2% ($35.7M total volume)
( Polymarket)

At 1.2%, this is a 82-to-1 catastrophe hedge -- but $35.7M in total volume sits behind it, the largest single Iran contract in today's data. Kharg Island (Iran's main crude export terminal) at 4.15% "no longer under Iranian control" carries the same logic. Both are asymmetric tail risks: if either resolves YES, WTI enters uncharted territory. Sophisticated traders are paying for that insurance at scale.

What to Watch This Week

Three critical dates stack up: April 21 (ceasefire extension decision), April 22 (peace deal deadline at 23%), April 30 (Hormuz normalization at 31.5%). The base case has April 22 passing without a deal (77% probability), shifting the narrative to whether the ceasefire simply extends again. Watch intermediary signals from Oman and Qatar -- any indication second-round talks are accelerating will show up in the Hormuz normalization contract before the headlines.

UPDATE: US Navy Seizes Iranian Ship -- First Blockade Interception, Ceasefire Now 65pct With Wednesday Deadline

The situation escalated sharply over the weekend. On Sunday, USS Spruance intercepted and boarded the Iranian-flagged cargo ship Touska in the Gulf of Oman -- firing into the engine room after a six-hour standoff. It's the first US seizure under the Hormuz blockade, and Iran's military headquarters called it "armed maritime piracy," promising a "swift response."

Same Hormuz that briefly reopened Friday? Back at virtual standstill. A 24-hour window collapsed into a ship seizure and another Iranian closure. Brent is up 5-7% to $95-97 this morning, WTI near $91. US equity futures lower. Steep backwardation in the crude curve -- June contracts up ~5%, December 2028 far flatter -- market pricing this as acute disruption, not structural.

Polymarket Snapshot -- 7:00 AM EDT, April 20

Ceasefire (Deadline: Wednesday, April 22)
- Ceasefire extended by April 21: 65% (was 74% on April 14)
- Ceasefire ends by April 21: 20%
- US-Iran diplomatic meeting by April 30: 86-88%
- Next meeting location -> Pakistan: 92%
- Jared Kushner leads US delegation: 85%

Deal Structure
- Permanent peace deal by June 30: 66%
- Nuclear deal by April 30: 35%
- Iran surrenders enriched uranium by Dec 31: 66%
- Iran agrees to unrestricted Hormuz in April: 24%
- US blockade lifted by May 31: 80%

Military / Regime
- Trump ends military ops by June 30: 81%
- US invades Iran before 2027: 34%
- Conflict ends by Dec 31: 97%
- Regime fall by April 30: 1% -- Regime fall by June 30: 9%
- Kharg Island seized by May: 19-21%

Oil Supply Context
- Hormuz normal by end of April: 28%
- Pre-war Hormuz flows: ~20M bbl/d; current: ~3.8M bbl/d ( IEA)
- 2026 demand destruction estimate: -80K bbl/d year-over-year
- Iran's new "Larak Corridor" announced April 19 -- tolled route south of Hormuz Island. Non-starter for most Western operators under OFAC sanctions rules.

The Trading Setup:

The 65% ceasefire extension probability still holds, but the Touska seizure breaks whatever diplomatic momentum existed going into Pakistan talks today. The tail -- 20% chance the ceasefire ends Wednesday -- is where the crude volatility trade lives. If Iran retaliates before Wednesday's deadline, $100 becomes the floor conversation.

The backwardation structure tells the story: market believes the supply crunch is acute, not permanent. With Hormuz at under 20% of pre-war volume and Iran promising a response, the next 36-48 hours are the highest-risk window of this conflict for energy markets.

Both Sides Now Seizing Ships -- Trump "No Rush," Brent Hits $107

The standoff has escalated materially since the April 19 update. Both sides are now actively seizing commercial vessels, and Trump's posture has shifted decisively away from urgency on a deal.

The Ship Seizures (April 22-23)

Iran's Revolutionary Guard boarded and seized two container ships near the Strait of Hormuz on April 22:

• MSC Francesca (Panama-flagged): Seized after being fired upon ~6 nautical miles off Iran's coast while transiting south through the strait. MSC is the world's largest shipping company.
• Epaminondas (Greek-owned): IRGC gunboat opened fire, causing significant bridge damage, then forced the vessel toward Iranian waters.
• Euphoria: Struck in a third incident, later found stranded on the Iranian coast.

Iran released video of commandos in speedboats storming the MSC Francesca -- a deliberate provocation showing fast-boat capability is operational. Iran cited "operating without permits and tampering with navigation systems" as justification.

On the US side: Bloomberg reported the US Navy intercepted two Iranian oil supertankers attempting to circumvent the blockade in the Gulf of Oman.

Trump's Wednesday Posture Shift

This is the critical development, not the ship seizures. Trump told reporters Thursday:

• He does not want to "rush" a permanent deal -- "Don't rush me."
• The US military could "eliminate" Iran's remaining capability in a single day
• He ordered the Navy to "shoot and kill" any Iranian vessels attempting to mine the Strait
• He acknowledged Iran's fast-attack boats had "not been considered much of a threat" before this week (they now are)

He separately announced Israel-Lebanon ceasefire extended three weeks, but oil markets shrugged.

Energy Market Reaction

Brent crude closed up 3%+ on Thursday, highest weekly gain since early March:

• Brent: $106.88/barrel (+1.7% Friday morning)
• WTI: $97.21/barrel (+1.4% Friday morning)

IEA Director Fatih Birol: "We are facing the biggest energy security threat in history. As of today, we've lost 13 million barrels per day of oil."

The Fast-Boat Problem

The tactical picture changed this week. Before the ceasefire, Iran used missiles and drones. Now Iran has shifted to speedboat swarms -- estimated hundreds to thousands of small boats, many hidden in coastal tunnels. Maritime security firms describe a "layered system of threats: shore-based missiles, drones, mines, electronic interference, and fast-attack vessels" that a naval blockade at the strait's entrance cannot fully neutralize.

What's Priced In by May

Haitong Futures: "If US-Iran talks fail to make key progress by end of April and fighting resumes, oil prices could climb to new highs for the year."

Prolonged Hormuz disruptions could push global inventories below five-year seasonal lows by late May/early June, reintroducing a supply-risk premium into oil prices -- Reuters/China Futures Research.

The Fed meeting April 29 is priced at 99%+ hold. Any sign energy-driven inflation is re-accelerating before that meeting would be the next major catalyst.
