Daily Market Mispricings: 2 Events Where We Disagree With Polymarket — May 2, 2026

TL;DROn May 2, 2026, Naly's sharpest Polymarket disagreement is Iran's Hormuz pledge market: 16c YES looks closer to 55c YES, not 84c NO. We also think a U.S.-Iran diplomatic meeting by May 15 is too cheap at 33c YES versus 63c fair value. The core reason is that fresh proposals are still moving through Pakistani mediators, so the process looks stalled on terms, not broken on contact.

Key Takeaways

Naly's biggest answer flip is Hormuz: the market prices YES at 16c, but fresh mediation and economic pressure push our fair value to 55c YES.

We also disagree with the market's NO lean on a U.S.-Iran diplomatic meeting by May 15, 2026 because active Pakistani mediation keeps a second session plausible.

In both markets, the key distinction is between a frozen final deal and a still-open contact channel; Polymarket appears to be pricing the first as if it guarantees the second.

The main risks are wording and trust: a vague Hormuz pledge may not satisfy resolution, and another canceled trip could kill the meeting setup.

Why we disagree: A fresh proposal, ongoing phone contact, and an already-tested Pakistan channel make another meeting likelier than the market implies.

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.

This is an answer flip, not just a confidence tweak. The quoted market price is 16c on YES, meaning a trader pays $0.16 now for a $1 binary contract if Iran publicly agrees to unrestricted commercial shipping through Hormuz by May 31, 2026; that 16c is also roughly the market-implied 16% YES probability. Our separate 55% YES estimate implies a 55c fair price on that same side. The 84c max payout if correct is distinct from the +39c fair-value edge between entry price and our fair value.

Causal Chain

Cause Cause: Iran keeps using Hormuz reopening as a bargaining chip in fresh proposals delivered through Pakistani mediators.

↓

Effect Effect: Because this contract resolves on an explicit agreement, not on fully normalized traffic, even an incomplete wider peace process can still produce a YES outcome.

↓

Projection Projection: If diplomacy stays alive for another two weeks, the odds of a public navigation pledge should rise faster than the market's current 16c YES price.

Key Factors

| Factor
▲ | Axios on April 27 reported that Iran's draft focused first on reopening the Strait of Hormuz and only later on nuclear talks, which matters because this market does not require a full grand bargain.
▲ | Axios on May 1 reported that Iran delivered a new response via Pakistani mediators, showing the specific Hormuz track is still active even after public setbacks.
▲ | Reuters on April 27 via Investing.com said traffic was still only a fraction of prewar norms, which raises economic pressure on all sides to produce a face-saving navigation statement.
▲ | Reuters on May 1 via Investing.com said Trump was dissatisfied and no second meeting was set, but it also said phone negotiations continued, which keeps the path to a public pledge open.
▼ | The biggest residual risk is wording: a statement that preserves tolls, conditions passage on sanctions relief, or falls short of "unrestricted" could still resolve NO.

Bayesian Calculation

Base rate: 16% from the market's current YES price on the binary contract.

Positive update: Fresh reporting shows Hormuz reopening remains one of the few concrete items Iran is actively putting on the table, which is exactly the kind of public commitment this market needs.

Negative update: U.S. distrust, UAE skepticism, and resolution wording risk all materially lower the odds that any statement will be both public and broad enough to count.

Naly estimate: 55% YES, implying a 55c fair price.

Alternative explanation: The market may be correctly assuming that Iran wants to keep some coercive leverage over the waterway, so even if talks advance it may offer a partial or heavily conditioned shipping formula that sounds conciliatory but still resolves NO.

What Would Make Us Wrong

We are wrong if Washington shifts toward a unilateral maritime coalition or renewed strikes instead of bargaining, or if Tehran publicly limits passage, keeps tolling authority, or refuses the word "unrestricted" in any formal statement before May 31, 2026.

This is also an answer flip. The quoted market price is 33c on YES, so a trader pays $0.33 now for a $1 binary contract if a U.S.-Iran diplomatic meeting occurs by May 15, 2026; that 33c doubles as the market-implied 33% YES probability. Our separate 63% YES estimate implies a 63c fair price on the same side. The 67c max payout if correct is different from the +30c fair-value edge between the market entry price and our fair value.

Causal Chain

Cause Cause: Pakistan is still carrying fresh proposals between Washington and Tehran, and both sides have already used Islamabad as a live negotiating channel.

↓

Effect Effect: Because the infrastructure, mediator, and agenda already exist, a second meeting requires less setup than the market's 33c YES price suggests.

↓

Projection Projection: If phone contact continues through the current ceasefire window, an in-person or formally recognized diplomatic session before May 15, 2026 remains more likely than not.

Key Factors

| Factor
▲ | AP on April 25 said the second round stumbled before it began, but it also showed Pakistan still hosted the channel and that Iran presented what it called a workable framework.
▲ | Axios on May 1 reported that a new Iranian response reached the U.S. via Pakistani mediators on Thursday, which means the negotiating channel is active in the immediate run-up to the deadline.
▲ | Reuters on May 1 via KSL.com said Trump praised Pakistan's mediation and that negotiations by phone were continuing, a sign the bottleneck is terms, not a complete communications breakdown.
▼ | Reuters on April 14 via The Business Standard reported both sides had previously kept a Friday-to-Sunday return window open, which lowers the friction to scheduling another session.
▲ | The main reason this can still fail is calendar compression: no date is set, and Trump has already shown he will cancel travel if he thinks the other side is stalling.

Bayesian Calculation

Base rate: 33% from the market's current YES price on the meeting contract.

Positive update: An active mediator channel, a fresh written proposal, and continuing phone negotiations all make another diplomatic meeting materially more plausible than a one-third chance.

Negative update: The absence of a scheduled date, plus public dissatisfaction from Trump, means the path can still break on optics or timing rather than substance.

Naly estimate: 63% YES, implying a 63c fair price.

Alternative explanation: The market may be right if both governments decide indirect calls and mediator shuttling are sufficient for now, avoiding the political risk of another face-to-face session even while negotiations technically continue.

What Would Make Us Wrong

We are wrong if the ceasefire deteriorates, Pakistan cannot lock in a venue and time, or either side demands preconditions that the other rejects before a meeting can be formally announced or held by May 15, 2026.

Fresh Checks

AP, May 1: Trump rejects Iran's latest proposal but negotiations continue by phone

Conclusion

The next catalysts are straightforward: whether Pakistan pins down another session, whether the White House keeps negotiations on the phone or names a venue, and whether any Iranian statement uses resolution-clean language around unrestricted Hormuz shipping. If those watchpoints break positively, both YES contracts should reprice quickly; if they fail, these answer-flip edges will disappear just as fast.

FAQ

Why is the Hormuz market still a YES flip if shipping remains disrupted?

Because the contract is about a public agreement on unrestricted shipping, not about traffic already returning to prewar levels on May 2, 2026.

Why does a 16c or 33c quote matter so much?

On a $1 binary contract, 16c YES or 33c YES is both the trader's entry price and a rough market-implied probability for that same contract side.

Why can Naly be above 60% on a diplomatic meeting with no date set?

Because the mediator, venue path, and communication channel already exist, so the remaining uncertainty is mostly political timing rather than full process creation.

What is the difference between max payout and fair-value edge?

Max payout is the profit if the contract resolves on your side, while fair-value edge is the gap between the current market price and Naly's estimate of what that side should trade for.

Methodology

We start from market-implied priors, convert those prices into explicit contract-side probabilities, then update them with fresh reporting, contract wording, and timeline risk. For roundup inclusion, we prioritize answer flips rather than same-side confidence tweaks, and we track how those calls perform on our track record.
