Polymarket prediction markets for June 19th and 20th resolved with a "No" outcome.

This resolution occurred because no military action took place on those specific dates.

However, markets for June 21st, 22nd, and 23rd resolved "Yes" after a US strike.

The United States conducted military strikes against Iranian nuclear facilities on June 21, 2025.

These strikes happened between 18:40 and 19:05 ET, triggering the "Yes" resolutions.

Reasons

The US military strikes directly caused the "Yes" resolution for June 21st.
The absence of strikes on June 19th and 20th led to their "No" resolution.
The timing of the military action determined the market outcomes.
Prediction markets are sensitive to real-world events occurring within their timeframe.

The military strikes on June 21st did not cause the Polymarket resolution for June 19th and 20th to be a 'No' outcome; that's just backward. The market resolved to 'No' for those earlier days because nothing happened then, simple as that. Thinking the later event made the earlier event null is like saying your internet outage today broke your Wi-Fi from last week. We need to set the record straight: the lack of activity on the 19th and 20th itself decided the outcome.

Polymarket prediction markets for June 19th and 20th resolved with a "No" outcome.

This resolution occurred because no military action transpired on those specific dates.

However, markets for June 21st, 22nd, and 23rd resolved "Yes" after the US military strike.

The US conducted military strikes against Iranian nuclear facilities on June 21, 2025.

This event directly triggered the "Yes" resolutions for the later markets.

Reasons

The US military strike on June 21st directly caused the "Yes" outcomes for subsequent markets.
Without the strike, these markets would likely have resolved differently, perhaps as "No.
The timing of the strike was crucial for the resolution of the June 21-23 markets.

The resolution of Polymarket's June 19th and 20th markets to 'No' wasn't triggered by military strikes on the 21st; that misunderstands the operational mandate of prediction markets completely. A market resolution is determined by whether the specific conditions for a 'Yes' outcome were met within its defined timeframe. If nothing happened by the 20th for the 19th/20th market, then 'No' was the only permitted outcome, regardless of later events on June 21st, just like a building permit denied on Tuesday isn't because of a new application on Thursday.

A longshot bet involves a single investor buying at least $2,500 in contracts.

This purchase must occur within one hour at a weighted average price of 0.35 or less.

These bets target low-probability outcomes in prediction markets.

If successful, longshot bets can generate substantial returns.

They are analyzed for potential insider trading signals or market mispricings.

Examples

A bet on a political event with a 10% chance of happening.
A large wager on an unexpected outcome in a financial market.
A significant investment in a sports underdog with very low odds.
A bet on a company's stock to surge despite poor current performance.

Defining a longshot bet as exactly $2,500 or more with a price under 0.35 in an hour feels a bit too rigid for spotting actual market anomalies.
It's like saying a significant scam only starts at £1,000; you’d miss 90% of the daily phishing attempts that add up.
A 20% difference in value, like a £2,000 bet, or a 25% longer time frame, say 75 minutes, could still show the exact same risk-to-reward ratio for the bettor, a 1 in 3 chance of a 10x return.
Those thresholds might exclude a lot of equally insightful data points just outside the arbitrary limits.

It's a bit like saying the rain today caused the ground to be dry yesterday, isn't it? Historically, events are judged on their own timeline; the Polymarket resolution for June 19th and 20th resolved as 'No' simply because no military action happened on those days. A later event, like the strikes on June 21st, can't retroactively cause the outcome of something that already passed. We've always gone by the playbook that the past is fixed, so what actually occurred on the 19th and 20th is what matters for those dates.

Longshot bets in military and defense markets show an unusually high success rate.

Over half of these longshot bets resulted in winning outcomes, defying typical probability.

This suggests that some bettors have access to non-public information.

Such information asymmetry could lead to market manipulation.

This contrasts with the general growth in sports longshot betting volume.

Examples

Military and defense longshot bets win 51.8% of the time.
Expected win rate for longshot bets is typically 35% or less.
This indicates an information advantage for some participants.
The total wagered on these winning outcomes was $9.3 million.
This outlier behavior is not seen in other political topics.

I disagree with the author here. As a HR Recruiter, I would make this conditional rather than decisive: the mechanism only carries if the surrounding constraints actually permit it.

Prediction markets are becoming more specific, focusing on exact dates for events.

This increased precision lowers the initial probability of an outcome occurring.

However, it significantly boosts potential profits for successful predictions.

Access to non-public timing information becomes much more valuable.

This creates a greater advantage for those with insider knowledge.

Examples

High precision markets had an average profit of $9,000 per winning bet.
Medium precision markets yielded $3,000 in profit per winning bet.
Low precision markets resulted in $1,325 profit per winning bet.
A 42% decrease in average price occurred with each precision step.
This led to a 126% to 200% increase in profits on winning bets.

I disagree with the author here. As a Nutritionist-Chef, I would make this conditional rather than decisive: the mechanism only carries if the surrounding constraints actually permit it.

Polymarket prediction markets for June 19th and 20th resolved as "No" for military action.

This outcome was due to the US military strikes on Iranian facilities occurring on June 21st.

The timing of the actual strike confirmed that no military action happened on the earlier dates.

This resolution highlights how real-world events impact prediction market outcomes.

The markets for June 21st and later resolved as "Yes" following the strike.

Reasons

No military action occurred on June 19th.
No military action occurred on June 20th.
The US strikes happened on June 21st, not earlier.
The markets accurately reflected the absence of action.
The resolution was based on the actual event timing.

Military and defense prediction markets show unusually high success rates for longshot bets.

Over half of these low-probability bets in military markets ended up winning.

This contrasts sharply with other political topics like elections, which stay within expected ranges.

Such a pattern suggests information imbalances not reflected in market prices.

This phenomenon points to a potential systemic insider risk within these markets.

Reasons

Longshot bets in military markets win 51.8% of the time, far exceeding the expected 35%.
Other political markets, like elections, show longshot win rates around 23.5%.
This disparity suggests that some participants have privileged information.
The high success rate indicates potential information asymmetry in defense topics.

The Anti-Corruption Data Collective (ACDC) released a policy brief in April 2026.

It analyzed insider trading risks within Polymarket's political and military betting pools.

The report found systemic indicators of insider trading in these markets.

Political markets, though few, account for a large share of Polymarket's trading volume.

Between 2021 and early 2026, $54.4 billion was wagered across 435,672 markets.

Examples

Political markets comprise only 4% of all markets but 36% of total trading volume.
These markets attracted $19.7 billion in wagers, over one-third of the platform's total.
On average, political markets have seven times the wagering volume of other markets.
Military markets show a 52% longshot win rate, suggesting non-public information use.
Approximately $8 billion was traded in markets identified as high insider-risk.

The ACDC brief on Polymarket risks, published in April 2026, cannot directly inform the settlement of markets that largely concluded before then.
The majority of the $54.4 billion wagered and 435,672 markets settled occurred between January 2021 and March 2026.
This means the market settlements were already a closed fact, indifferent to the brief's later analysis.
It is like a report on past network issues; it describes what happened, but doesn't change past connectivity.
We must separate an analysis of events from the events themselves.

Polymarket prediction markets for June 19th and 20th resolved with a "No" outcome.

This resolution occurred because no military action transpired on those specific dates.

However, markets for June 21st, 22nd, and 23rd resolved "Yes" after the US military strike.

The US conducted military strikes against Iranian nuclear facilities on June 21, 2025.

This event directly triggered the "Yes" resolutions for the later markets.

Reasons

The US military strike on June 21st directly caused the "Yes" outcomes for subsequent markets.
Without the strike, these markets would likely have resolved differently, perhaps as "No.
The timing of the strike was crucial for the resolution of the June 21-23 markets.

It's true that the military strikes on June 21st confirmed no action on the 19th and 20th, but calling them the trigger for a 'No' resolution on those earlier dates is stretching it. Here, if the 6 PM bus doesn't show up, we don't need a later announcement to confirm it never ran; the absence of the bus is the resolution. In this market, the lack of action on the specific dates means 'No' anyway, regardless of what happens later. The resolution for the 19th and 20th was simply a function of time passing without incident, not an external event from days later. That’s like saying the new month confirms the old one ended.
