Prediction markets are supposed to crowd-source the wisdom of the masses, but sometimes those masses look a little too wise. A recent investigation by blockchain analytics platform Bubblemaps has raised serious eyebrows, uncovering a cluster of crypto wallets that managed a mind-boggling 98% win rate on Polymarket. The focus of their uncanny accuracy? Major U.S. military operations.
In total, this small group of accounts walked away with $2.4 million in profits, sparking intense debate over whether someone on the inside is using decentralized platforms to cash in on geopolitical conflict.
Inside the Uncanny 98% Win Rate on Military Contracts
According to Bubblemaps, a group of nine interconnected wallets collectively raked in millions by perfectly timing the market. These accounts systematically placed massive wagers just moments before critical geopolitical events unfolded.
The cluster focused its heavy betting on a few highly specific, volatile contracts:
-
The February 28 U.S. strike on Iran: Four of these wallets alone walked away with roughly $400,000 each in profit by betting correctly on this single event.
-
The rumored fate of Iranian Supreme Leader Ayatollah Ali Khamenei.
-
The U.S.-Iran ceasefire agreement.
While definitive proof of insider trading remains elusive, the on-chain data is incredibly loud. Bubblemaps CEO Nicolas Vaiman noted that the trail is highly “symptomatic of someone with an unfair informational advantage.”
The wallets were all funded through centralized cryptocurrency exchanges (CEXs) and third-party mixing services within a tightly coordinated timeframe. To make things even more suspicious, the accounts placed a series of small, losing bets on February 20. Analysts believe this was a deliberate attempt to mess with their win-rate metrics, blend into the crowd, and avoid drawing attention to their upcoming windfall.
Washington Steps In to Ban War and ‘Death Bets’
This uncanny streak of good luck hasn’t just caught the attention of crypto sleuths; it’s also ringing major alarm bells in Washington. The controversy has added fuel to a raging fire over how to police decentralized prediction markets like Polymarket and Kalshi. Because these platforms allow users to trade pseudo-anonymously, tracking down the actual individuals pulling the strings is notoriously difficult.
In direct response to these suspicious trades, U.S. Democratic Senator Adam Schiff introduced the DEATH BETS Act on March 10. The proposed legislation aims to legally bar federally regulated prediction markets from hosting contracts tied to war, terrorism, assassinations, or individual deaths.
“We cannot say with certainty that this was an attempt to hide, but it is suspicious that funds were routed through CEXs and third-party services before funding new Polymarket accounts, effectively covering their tracks.” — Nicolas Vaiman, CEO of Bubblemaps
The regulatory clampdown isn’t just happening at the federal level. California Governor Gavin Newsom also signed an executive order aimed at preventing public servants from leveraging non-public information to trade on political or economic events they might directly influence.
As prediction markets continue to boom—with politics and global conflicts representing a massive chunk of the trading volume on platforms like Polymarket—the line between “collective intelligence” and insider trading is getting razor-thin. Whether these platforms can successfully self-regulate or face heavy-handed government shutdowns remains to be seen, but the era of anonymous, highly lucrative “war betting” is officially under the microscope.
