For years, the pitch for prediction markets like Polymarket has been simple: the “wisdom of the crowds” is a more accurate barometer of truth than traditional polling or punditry. The theory is that when people put their own money on the line, they are incentivized to find the most accurate information available. It turns out, however, that some people aren’t just finding information—they may already possess it.
New data suggests that the “wisdom” driving some of the platform’s most improbable wins isn’t a result of superior analysis, but rather privileged access. An analysis by the Anti-Corruption Data Collective (ACDC), a non-profit research and advocacy group, indicates a startling disparity in win rates for “long-shot” bets, particularly those involving military and defense actions.
The findings point to a systemic advantage for a small group of high-stakes bettors. While the average bettor struggles to predict the volatility of global conflict, a subset of users wagering significant sums on unlikely outcomes is winning at rates that defy statistical probability.
The Anatomy of a ‘Long-Shot’ Win
To identify potential insider trading, the ACDC focused on “long-shot” wagers—defined as bets of $2,500 or more placed on outcomes with odds of 35 percent or less. In a fair market, these bets should fail the vast majority of the time. Instead, in markets centered on military and defense actions, these high-stakes long shots had an average win rate of approximately 52 percent.
The discrepancy becomes more glaring when compared to other sectors of the platform. In politics-focused markets, the win rate for similar long shots drops to 25 percent. Across the entirety of the platform, the win rate for these bets is a mere 14 percent. This suggests that while political outcomes remain somewhat unpredictable, military actions are being anticipated with an accuracy that suggests the bettors are not guessing.
| Market Category | Average Win Rate |
|---|---|
| Military and Defense | ~52% |
| Politics-Focused | 25% |
| All Platform Markets | 14% |
A Regulatory Vacuum in Prediction Markets
The ability to profit from this information gap highlights a significant legal loophole. In the traditional stock market, trading on non-public, material information is a federal crime. In sports betting, “inside information” can lead to lifetime bans and criminal prosecution. But prediction markets occupy a murky regulatory middle ground.
Polymarket, which operates as a decentralized platform on the Polygon blockchain, has already faced scrutiny from the Commodity Futures Trading Commission (CFTC). In 2026, the platform reached a settlement with the agency regarding its accessibility to U.S. Users, but the settlement focused largely on registration and jurisdictional issues rather than the ethics of the information being traded.
Unlike a corporate board room or a professional sports league, there is no centralized governing body that can easily monitor who possesses “insider” knowledge of a military strike or a defense contract shift. When the “insider” is a government official, a defense contractor, or a military strategist, the potential for market warping—and personal profit—is immense.
The On-Chain Paper Trail
From a technical perspective, the particularly nature of Polymarket is what makes this analysis possible. Because the platform is built on a public blockchain, every transaction, bet, and payout is recorded in an immutable ledger. While users may remain pseudonymous, their behavior is entirely transparent.
As a former software engineer, I find the irony palpable: the transparency of the blockchain, designed to prevent the kind of opaque manipulation found in traditional finance, is now providing the evidence of that same manipulation. Researchers can track a specific wallet address, see a $10,000 bet placed on a low-probability military event hours before it occurs, and watch the payout hit the wallet shortly after.
This transparency creates a “cat-and-mouse” game. Sophisticated insiders may attempt to hide their tracks by splitting bets across multiple wallets or using “mixers” to obscure the origin of their funds, but the aggregate data analyzed by groups like the ACDC still reveals the overarching pattern of anomalous success.
Why Military Insider Betting Matters
The implications of this trend extend far beyond the wallets of a few lucky bettors. When military actions become tradable assets, the incentive structure for decision-makers shifts.
- Market Manipulation: Large bets can move the odds, potentially signaling to other actors (including foreign adversaries) that a specific action is imminent.
- Conflict of Interest: If policymakers or those with access to intelligence can profit from the timing of a military operation, the neutrality of that operation is called into question.
- Erosion of Trust: Prediction markets are increasingly used by journalists and analysts as “real-time” data. If these markets are skewed by insiders, they become tools of misinformation rather than instruments of truth.

The next critical development will be the upcoming quarterly review by the CFTC regarding the compliance of decentralized prediction markets with existing commodities laws. This review is expected to address whether “insider trading” in non-financial markets falls under their enforcement umbrella.
