Keiko Fujimori is trading like a 67c favorite on Polymarket, but our fair value on the YES side is just 32c, which makes NO our top answer at 68%. That is the cleanest answer flip in today's slate, and it sits alongside two Iran contracts where the market still prices a formal U.S. climbdown more generously than the latest blockade and sanctions signals justify.
- Keiko's first-place finish in Peru looks real, but her roughly 17% first-round vote share still points to a runoff coalition problem, not a commanding general-election mandate.
- The Strait of Hormuz reopening story and the U.S. blockade story are no longer the same thing; shipping relief can happen without Trump formally announcing that the blockade is lifted.
- Frozen Iranian assets remain a bargaining demand from Tehran, but Washington's latest moves still point toward tighter financial pressure rather than a cash release.
- All three setups are answer flips, not just confidence disagreements: Polymarket leans YES in each case, while we lean NO in each case.
3 Mispricings at a Glance
Will Donald Trump announce that the United States blockade of the Strait of Hormuz has been lifted by April 30, 2026?
Why we disagree: Washington is still using the blockade as leverage, not signaling a formal rollback.
Will Trump agree to unfreeze Iranian assets in April?
Why we disagree: Recent U.S. actions are tightening sanctions and waivers, which is the opposite of an April cash release.
Why we disagree: First-round strength overstates runoff strength when anti-Fujimori voters still have room to consolidate.
How to read this: Polymarket Top Answer and Naly Top Answer show the final answer each side sees as most likely. Max Payout if Correct shows the gross upside from the current quote to the $1 settlement if the selected contract side wins. The horizontal graph still shows where that selected side sits on a 0c to $1 range for Polymarket versus Naly.
Will Donald Trump announce that the United States blockade of the Strait of Hormuz has been lifted by April 30, 2026?
As of April 17, 2026, Polymarket is quoting the YES side at 58c, which is both the current entry price and roughly the market-implied probability on a $1 binary contract. Our separate estimate on that same YES side is 24%, which maps to a 24c fair price. That makes this an answer flip: Polymarket's top answer is YES, while ours is NO. A 58c YES share can return at most 42c if it resolves true, but that max payout is not the same thing as the fair-value edge, which is negative 34c versus our fair price.
Causal Chain
Key Factors
| Factor | |
|---|---|
| The White House's April 14 release still described the naval blockade as a core show of strength, which argues against an imminent voluntary rollback. | |
| AP reported on April 16 that the U.S. military expanded enforcement to Iran-linked ships worldwide, raising the political and operational cost of reversing course immediately. | |
| AP reported on April 17 that commercial passage through Hormuz was described as open, but also said it was not yet clear what that meant for the U.S. blockade. | |
| The same April 17 AP report said mediators still face unresolved sticking points on Iran's nuclear program, the Strait of Hormuz, and wartime compensation. |
Bayesian Calculation
Alternative explanation: Trump could decide that a partially reopened shipping lane is good enough for a victory lap and simply relabel a tactical easing as a formal lift. That is the strongest case against our NO.

Will Trump agree to unfreeze Iranian assets in April?
As of April 17, 2026, the quoted side is YES at 52c, so the market is effectively saying there is about a 52% chance of an April agreement to unfreeze assets. Our estimate on that same YES side is 18%, which implies an 18c fair price. That is another answer flip: the market's top answer is YES, but ours is NO. A 52c YES share can return at most 48c if it resolves true; the fair-value edge is different and sits at negative 34c against our fair price.
Causal Chain
Key Factors
| Factor | |
|---|---|
| AP reported on April 15 that Treasury Secretary Scott Bessent said the administration wants to ramp up economic pain on Iran rather than ease it. | |
| AP reported on April 14 that the short-term waiver for stranded Iranian oil will expire on April 19 and will not be renewed. | |
| AP reported on April 11 that the first direct talks ended without agreement, leaving the core dispute unresolved. | |
| In that same April 11 AP report, releasing frozen assets was described as one of Iran's red lines, which matters because it framed the issue as an unmet demand, not an accepted U.S. concession. |
Bayesian Calculation
Alternative explanation: Trump could package a limited escrow release or a humanitarian carve-out as an asset unfreeze and claim a diplomatic breakthrough even without a full agreement.
Fresh Checks
Will Keiko Fujimori win the 2026 Peruvian presidential election?
As of April 17, 2026, Polymarket is quoting the YES side at 67c, which means buyers are paying 67 cents for a contract that pays $1 only if Keiko Fujimori wins. Our estimate on that same YES side is 32%, or a 32c fair price. This is the clearest answer flip in the group: the market's top answer is YES, while ours is NO. A 67c YES share can return at most 33c if it resolves true, while the fair-value edge is negative 35c against our estimate.
Causal Chain
Key Factors
| Factor | |
|---|---|
| AP reported on April 16 that Fujimori led with 17.06% of the vote with 93% of ballots tallied, which is a lead but not a broad mandate. | |
| AS/COA's April 16 roundup noted that this is her fourth presidential campaign and that she lost the last three runoffs. | |
| AS/COA's April 15 reaction piece described the likely runoff as polarizing, which is exactly the environment where anti-Fujimori consolidation matters most. | |
| Official ONPE results still point to a fragmented electorate rather than a coalition already assembled around Fujimori. |
Bayesian Calculation
Alternative explanation: If the runoff opponent is badly damaged, too ideologically extreme, or unable to unify the anti-Fujimori vote, her machine politics and familiarity could finally break through.

Conclusion
The watchpoints ahead are straightforward. On Iran, the key catalysts are whether the ceasefire gets extended, whether Washington trades leverage for a headline concession, and whether any formal memo changes the status of the blockade or frozen assets. In Peru, the market needs to focus less on who topped round one and more on who can survive the runoff coalition math once the field compresses.
Methodology
We start with the market price on one contract side, translate our own probability estimate into a fair cents price on that same side, and then ask whether the latest causal evidence supports a higher or lower number. We care more about mechanism than narrative: what changed, how that changes incentives, and whether the market has already priced it. You can review our calibration over time on the track record page.
