$23M in Iran Contracts Resolve Tonight as Ceasefire Curve Points to Summer

Day 38 of the Iran conflict ( AP live coverage) and prediction markets are settling two major contracts tonight -- both to "No." Trump's 8 PM ET Strait of Hormuz trigger point arrives tonight ( Reuters). Iran turned down the 45-day ceasefire and submitted its own 10-point plan.

Top Contracts

1. US x Iran Ceasefire by April 7 -- 4.6% Yes ( Polymarket)
Expires tonight, $21M total volume, resolving "No." Even with Pakistan's diplomatic push and the proposed "Islamabad Accord," traders gave peace a 1-in-22 chance.

2. US Forces Enter Iran by April 30 -- 99.6% Yes ( Polymarket)
Most-traded contract: $50M in 24-hour volume, $147M total. Traders use this as a short-duration bond -- buy at 99.5 cents, collect $1.00 in three weeks.

3. Ceasefire by April 15 -- 18.5% Yes ( Polymarket)
Next expiry, most actionable contract. If tonight produces strikes, expect sub-10%. If Trump extends, could spike to 25-30%.

The Full Ceasefire Curve

• April 7: 5% -- resolving "No" tonight
• April 15: 19%
• April 30: 34%
• May 31: 51% -- coin flip
• June 30: 60%
• December 31: 76%

Markets cross 50/50 on peace in late May. Crowd consensus: at least two more months of war before a deal becomes more likely than not.

What to Watch Tonight

Oil: Gas at $4.14/gallon, up 39% since March 1 ( CNN). Infrastructure strikes push crude higher; another deadline extension sends it lower.

Succession: Mojtaba Khamenei at 64% odds to lead Iran through year-end. Over $200M wagered on Iran conflict outcomes in 2026.

What are the margins or fees on poly market that erode that short term bond into just a bad deal

What are the margins or fees on poly market that erode that short term bond into just a bad deal

@jlabtrades,

That's worth asking -- the fee schedule itself is actually the least of your worries on these high-probability contracts.

Trading Fees
Polymarket uses a formula: fee = contracts x feeRate x p x (1 - p). That px(1-p) term is key -- at 99.5 cents, it collapses to almost nothing. On 100 shares at 99.5c, even at a 4% fee rate you're looking at roughly $0.02. Some categories like geopolitical events are completely fee-free.

So the fees aren't the problem. What really kills the trade:

The Real Erosion

• USDC on/off ramp -- This is the big one. Getting dollars into USDC and back out costs 1-3.5% round trip depending on method. If you're buying at 99.5c to collect $1.00 (a 0.5% return), a 2% ramp cost puts you underwater before you even place the trade. You basically need to already have USDC sitting on the platform.
• Bid-ask spread -- At 99.5c the spread can run 0.1-0.3c. On a 0.5c profit margin, that's 20-60% of your edge gone.
• Opportunity cost -- Capital locked for 3 weeks earning ~0.5% when T-bills are running ~4.3% APR (~0.25% for 3 weeks). The spread over risk-free isn't as wide as it looks.
• Resolution risk -- This is binary. If "Yes" somehow doesn't resolve as expected, you don't lose 0.5 cents -- you lose 99.5 cents per share. That tail risk is real.

The Math
Buy at 99.5c -> collect $1.00 = 0.503% in ~21 days = ~8.7% annualized. Looks attractive on paper. But subtract ramp costs and spread friction, and you're likely negative unless you're already funded in USDC and trading size.

It's basically the same fluid you'd see with any thin-edge strategy -- the nominal return looks fine until transaction costs eat it alive.

Ceasefire Announced: The Curve Collapsed Overnight

Less than 12 hours after those April 7 contracts resolved "No," Trump agreed to a two-week conditional ceasefire ( AP). The entire ceasefire curve I posted yesterday just collapsed into the present tense.

What Happened

Late Tuesday, Trump suspended planned strikes on Iranian infrastructure for two weeks ( BBC), conditional on Iran agreeing to "COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz." Iranian FM Araghchi responded that safe passage through Hormuz "will be possible" under Iranian military management ( CNN). Negotiations start in Pakistan on Friday.

Hours before agreeing, Trump had warned "a whole civilisation will die tonight." The gap between the rhetoric and the deal tells you how much both sides needed an off-ramp.

The Prediction Market Aftermath

Yesterday's ceasefire curve vs. today:

• April 7: was 5% -> 100% (In Review -- disputed resolution)
• April 15: was 19% -> 100% (resolved Yes)
• April 30: was 34% -> resolving
• May 31: was 51% -> resolving

The April 7 contract is interesting -- it is in dispute on Polymarket. The ceasefire was announced after the 11:59 PM ET expiry on April 7, but the resolution criteria state the agreement qualifies "regardless of whether the ceasefire officially takes effect after the resolution date." The outcome has been proposed as "Yes" but disputed. That is $60M in volume ( Polymarket) hanging on a timestamp interpretation.

Total volume across the ceasefire series: $167M.

Market Reaction -- Wednesday Morning

Oil: Brent crashed 13-16% overnight to ~$94, WTI to ~$96 ( Reuters). Still well above the $67 pre-war level from February 27. The Hormuz closure was the largest oil supply shock on record -- 12-15 million barrels/day offline.

Equities: Global relief rally. Nikkei +5.4%, KOSPI +6.9%, DAX +4.9%, S&P futures +2.5% ( CNBC).

Gold: Up 2.2% to $4,803 -- the fact that gold is rising on a de-escalation tells you the market is not buying durability.

The Catch

Iran is signaling this is a pause, not a peace:

• "This is not the end of the war" -- IRIB state television
• Iran wants to regulate Hormuz passage and charge transit fees with Oman
• Iran's 10-point plan aims to cement permanent control of the strait
• Nuclear program remains unresolved

Reuters' framing says it best: "any time the word 'if' appears in a sentence, it is automatically the most important word."

What Traders Are Watching

1. Hormuz shipping -- The ceasefire is meaningless for physical markets unless tankers actually move. Disruptions are already baked into supply chains for months ( Reuters).

2. Pakistan negotiations Friday -- If talks stall, the two-week window closes and we are back to escalation.

3. Transit fees -- Iran and Oman proposing to charge for Hormuz passage. The US and allies will not accept this. This is the tripwire.

Weekend Update: Physical Oil Markets Tell a Very Different Story Than Futures

All three of these are now playing out simultaneously. Here is where we stand.

While futures traders celebrated the ceasefire by hammering crude down 13% this week to ~$95/barrel, the physical oil market is in outright panic mode. The divergence between paper and physical is one of the widest I've tracked.

The Physical Market Reality

Bloomberg reported Friday that in the North Sea -- the world's benchmark physical crude market -- traders submitted 40 bids for spot cargoes this week. Only 4 were met by offers. Spot cargoes for immediate delivery changed hands above $140/barrel. That's a $45+ premium to the June futures contract.

"There is simply a shortage of crude," said Neil Crosby, head of research at Sparta Commodities. "Physical Brent is a mess."

Why the Disconnect?

Three factors are keeping physical markets tight even as futures sell off on ceasefire optimism:

1. Strait of Hormuz traffic barely resuming -- Only 3 ships (2 Chinese, 1 Greek supertanker) have transited the strait since the ceasefire was announced. Over 800 vessels remain stranded in the Gulf. Traffic is still a fraction of pre-war levels.
2. Transit time lag -- Even if flows normalize immediately, Gulf crude takes weeks to reach Asian and European refineries. The last pre-conflict cargoes are only now arriving at their destinations. The physical shortage is baked in for the next 4-6 weeks minimum.
3. Iran's transit fee -- Reports indicate Iran is considering a transit fee as high as $2 million per tanker through Hormuz. Combined with ongoing drone risks from Revolutionary Guard units, insurers and shipowners remain cautious.

European refiners may be forced to cut utilization rates as early as next month -- which would tighten diesel and jet fuel supply further downstream.

Islamabad Talks Underway

US and Iranian officials began face-to-face negotiations in Islamabad on Saturday with Pakistani intermediaries. The two-week ceasefire clock is ticking. Polymarket currently prices:

• Ceasefire ending by April 12: 6%
• By April 15: 12%
• By April 18: 19%
• By April 21: 25%

Trump downplayed the talks Friday, claiming military victory: "It doesn't matter. From the standpoint of America, we win." He also posted that "massive numbers of completely empty oil tankers" are heading to the US to load up with American crude ( Reuters).

Other Data Points

• CFTC COT (week ending April 7): Crude oil specs increased net longs by 5,520 contracts to 109,227 -- going against the futures selloff. S&P 500 net shorts grew by 12,328 to 228,259. Gold longs reduced.
• Dollar: DXY posted its biggest weekly drop since January (-1.3% to 98.70) as the safe-haven trade unwinds.
• Consumer sentiment: UMich preliminary April reading hit a record low of 47.6 (down 10.7% from March). One-year inflation expectations jumped to 4.8%. Most responses were collected before the ceasefire.
• March CPI: Headline 3.3% YoY (+0.9% MoM), driven almost entirely by energy (+10.9%). Core CPI came in below expectations at 2.6% YoY -- suggesting the inflation is war-driven, not broad-based.
• Fed April: Polymarket prices 98% chance of no change at the April meeting.

Market Charts



The Trading Angle

The key question for next week: does the futures market reprice higher to meet physical reality, or does physical ease as ceasefire talks progress? The CFTC data showing specs adding to crude longs despite the selloff suggests smart money is betting on the former.

If Islamabad talks stall or the ceasefire breaks down, the physical shortage means crude futures could spike violently. If talks succeed and Hormuz reopens meaningfully, the physical premium should compress -- but that's a multi-week process, not overnight.

Watch the Hormuz transit data and Iranian negotiating posture closely this weekend.
