Systemic insider risk occurs when low-probability bets consistently succeed across related markets.

This pattern suggests underlying information advantages not reflected in market prices.

It points to a systemic issue rather than isolated incidents of luck or mispricing.

Such risks are particularly evident in markets susceptible to insider knowledge.

Recent legal actions against athletes highlight the practical dangers of these markets.

Exemples

A rise in individual player betting markets increases insider risk.
Sports betting longshots have seen a significant increase in success rates.
Federal indictments of athletes confirm the real-world threat of manipulation.
Military and defense markets also show signs of unreflected information asymmetries.
High success rates on longshot bets can signal systemic insider activity.

Saying insider manipulation in specific betting markets is just an "item of" systemic insider risk feels like we're still chasing a losing idea. If we hadn't already put so much sunk time into connecting them, would we still think they're directly linked like that? What if the manipulation in a sports bet was just one bad apple exploiting a unique loophole, like a referee fixing a single game, not some wider market problem? It’s not automatically systemic everywhere just because one person got caught.

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.

Raisons

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.

Raisons

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.

Polymarket allows users to trade blockchain-based contracts on real-world event outcomes.

These contracts are priced between $0 and $1, reflecting implied probabilities.

Winners receive $1 per contract when the market settles, enabling profit from mispriced outcomes.

The Anti-Corruption Data Collective found insider trading indicators in political and military markets.

This high-risk trading volume represents 36% of Polymarket's total activity.

Raisons

Polymarket's design allows users to capitalize on information advantages.
The platform's structure makes it possible to detect unusual trading patterns.
The ability to profit from mispriced outcomes incentivizes insider activity.
High trading volumes in political markets attract more sophisticated traders.
The $0-$1 contract pricing model simplifies profit calculation for insiders.

Is the Polymarket trading system really the cause of insider trading, or just a place where it happens?
It seems the platform's ability to trade outcomes between 0 and 1 is simply a venue for action.
If someone has non-public information on a political event, they could use any system; the system itself doesn't create the information.
For example, if a government official knows about an upcoming policy change, that knowledge is the driver, not the mechanism for placing a bet.

Eight crypto wallets profited significantly from Polymarket's Iran strike markets.

These wallets secured winning longshot positions after the June 21, 2025 strike.

Together, they realized $1.8 million in profits from these bets.

One single wallet alone made nearly $500,000.

This occurred due to pre-strike longshot bet placements.

Raisons

The precise timing of the strike was difficult to anticipate.
The operation used deception, including decoy bombers.
Long-range stealth aircraft required no visible regional buildup.
Rising tensions and prior Israeli strikes indicated heightened risk.

It's easy to say those US military strikes on Iranian nuclear facilities "enabled" crypto wallet profits, but that feels like missing the real story, the human element behind the numbers. Eight crypto wallets made a killing on Polymarket after the strikes, almost like someone knew the ending to the film before it screened. That kind of longshot payout, with one wallet grabbing nearly half a million dollars, implies more than just good luck; it suggests a whisper in the dark from someone with inside information about the upcoming scene.

Wallets with extremely high win rates and minimal selling activity are flagged as potential insider traders.

These traders hold winning contracts until market settlement, showing strong confidence in the outcome.

This behavior distinguishes them from other successful traders who sell early to lock in profits.

Such patterns are a key indicator for identifying insider risk in prediction markets.

Exemples

They consistently pick winning outcomes.
They rarely sell their positions before the market closes.
They hold contracts until the final settlement.
They demonstrate high conviction in their trades.

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.

It's easy to point to specific player betting manipulations and say the whole system is broken. But calling it "systemic insider risk" overstates the case without showing how one bad apple actually poisons the entire barrel.
If the problem only shows up here and there, like a few players getting caught, it’s not really a systemic issue; it's just individual misconduct. You must show the clear mechanism that connects these specific incidents across various markets for it to be truly systemic.

The volume of winning bets on Polymarket political markets increased nearly four-fold.

This surge occurred between late 2025 and early 2026.

A significant rise in sports longshot betting contributed to this overall increase.

Sports longshot bets grew from $103 million to $124 million in this period.

This growth suggests a potential for insider risk in these markets.

Raisons

Sports longshot bets increased by over 20% in early 2026.
The success rate of sports longshot bets nearly doubled.
Individual player markets are more vulnerable to manipulation.
Federal indictments show real-world risks of sports betting conspiracies.

A mere $21 million increase in sports longshot bets, while an uptick, won't unilaterally drive a nearly four-fold surge in Polymarket political market winnings. That's like expecting a slightly bigger puddle to cause a flash flood; the scale of the cause just doesn't match the peak effect claimed. You need a much larger asymmetry in capital or a major event, such as a presidential election with huge public interest, to really unlock that kind of full expression in market volume. This modest change isn't the upper bound of what's possible.

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.

Exemples

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.

Ouvrir le document source à ce paragraphe· Insider_Risks_in_Polymarket_Political_Markets_ACDC.pdf

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.

Exemples

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.

A military strike occurred in June 2025 against Iran, using stealth aircraft and decoy bombers.

This event was the target outcome for several day-specific prediction markets on Polymarket.

Anomalous trading behavior, specifically sharp price accelerations, preceded the strike.

These price spikes were observed across multiple day-specific market contracts.

This suggests traders prioritized speed over price efficiency due to time-sensitive information.

Raisons

Traders rapidly submitted wagers, exhausting willing counterparties at low prices.
They then offered increasingly aggressive prices to find new counterparties.
This caused abrupt price accelerations, unlike typical gradual trading movements.
Sudden price acceleration indicates traders valued speed over price efficiency.
This behavior is consistent with trading on time-sensitive, insider information.

Assuming a military strike in June 2025 would be a uniform resolution event for prediction markets seems like a big gamble; real-world scenarios often introduce too many unpredictable variables for such clean outcomes. What if the strike is called off last minute, or if the initial intelligence on stealth aircraft turns out to be misdirection? Even with sophisticated prediction markets, the actual impact or even the timing of a major geopolitical event can have a lot of downside risks for market clarity, like when an expected central bank announcement gets pushed back.

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.

Exemples

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.

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.

Raisons

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.

Longshot bets are defined as purchasing positions priced at or below 0.35 with trade sizes of at least $2,500.

The win rate measures the proportion of these wagers that successfully resolve to winning outcomes.

Among political prediction markets, Military and Defense topics have the highest longshot win rate at 51.8%.

Conversely, Central Bank Decisions and Politician Attendance show the lowest longshot win rates, below ten percent.

Exemples

Military and Defense topics have a 51.8% longshot win rate.
Politician Speech and Election topics show win rates around 23%.
Central Bank Decisions have a 9.1% longshot win rate.
Politician Attendance has the lowest longshot win rate at 8.3%.

A 51.8% win rate for longshot bets on Military and Defense topics seems high, but I'd be looking at the conditions that could cause a complete drawdown if things shift.
If an unexpected global event like a major conflict occurs, the downside for those bets could be absolute, making any previous win rate irrelevant.
It's like thinking your pension pot is safe because the market was up last year; one big crash can wipe out decades of careful planning, leaving you with little to exit with.

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.

Exemples

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.

Ouvrir le document source à ce paragraphe· Insider_Risks_in_Polymarket_Political_Markets_ACDC.pdf

It's a bit much to say a single report on insider trading risks from the Anti-Corruption Data Collective automatically explains why $54.4 billion got wagered on Polymarket.
They've got an incentive to highlight problems, which is fine, but that doesn't mean their findings are the sole motive for everyone else's betting habits.
Plenty of things draw people to bet big, not just the potential for shady dealings; often it's just the thrill or a perceived opportunity, like when I tried to make a quick buck on a stock tip back in '98 and lost my shirt.
We should always ask who stands to benefit from making such a strong connection.

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.

Raisons

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.

Before the strike, trading activity showed typical market behavior.

Most participants were retail traders or large investors, with no perfect win rates.

However, after the strike, several wallets emerged with extremely high success rates.

These wallets held their positions until settlement, suggesting confidence in the outcome.

This shift indicates a change in trading patterns following the strike event.

Exemples

Pre-strike markets had typical retail and whale trading patterns.
No wallets achieved a 100% win rate before the strike.
Post-strike markets showed wallets with extremely high win rates.
These high-win wallets held positions until market resolution.
This behavior contrasts with typical profit-taking by whales.

A sudden shift to high-win wallets might seem like a new market nature, but we need to consider the full picture to avoid a misinterpretation. What if the market size or liquidity dropped significantly post-strike? A smaller pool of participants or fewer available contracts could easily skew those win rates without any underlying change in market integrity, which means it could be an anomaly not a new problem.

The human desire to see an underdog win, whether in sports or in bigger, graver scenarios, often drives those long-shot bets, not necessarily some grand secret. I see it when my students try to guess which team will win the local navétane football match, picking the team everyone else dismisses because they want to see a surprise victory. It's the story of the unexpected hero, the big payoff against all odds, that holds the real sway, rather than some hidden intel no one else possesses. This narrative of hope and chance, a real beat in our lives, often feels more compelling than dry data about information asymmetry.
