Bubblemaps flags nine-wallet Polymarket cluster with $2.4M profit and 98% win rate
The wallets’ biggest positions were timed just ahead of major US military-related developments, reviving insider-trading scrutiny.
Bubblemaps says it identified a cluster of nine Polymarket wallets that earned $2.4 million with a 98% win rate on contracts tied to major US military operations. The firm says the wallets repeatedly placed large bets shortly before key developments, a pattern it describes as consistent with an unfair informational edge but not definitive proof of insider trading.
Key Takeaways
- A nine-wallet cluster on Polymarket generated $2.4 million in profit with a 98% win rate on US military-operation contracts, per Bubblemaps.
- Bubblemaps tied the wallets’ largest bets to pre-event timing around the Feb. 28 Iran strike and other military-related outcomes, including the killing of Iranian Supreme Leader Ayatollah Ali Khamenei and a US-Iran ceasefire agreement.
- The funding trail showed tight-timeframe deposits via centralized exchanges and additional routing through CEXs and third-party services before new Polymarket accounts were funded.
- Sen. Adam Schiff introduced the DEATH BETS Act on March 10 to restrict federally regulated prediction markets from listing war, terrorism, assassination, and death-related contracts.
Bubblemaps Spots a Nine-Wallet Polymarket Cluster With $2.4M in Profits
Bubblemaps published an investigation on May 19 describing what it says is a coordinated cluster of nine Polymarket wallets that collectively earned $2.4 million with a 98% win rate on contracts tied to major US military operations.
The dataset matters less for the raw PnL than for the repeatability of the pattern. A near-perfect hit rate on high-sensitivity geopolitical contracts is the kind of footprint that pulls prediction markets back into the insider-trading narrative, even before any identity attribution lands.
Bubblemaps said the wallets’ major bets were placed shortly before major military developments. The examples cited included the Feb. 28 attack on Iran, the killing of Iranian Supreme Leader Ayatollah Ali Khamenei, and a US-Iran ceasefire agreement.
The Trade Pattern Bubblemaps Flagged: Pre-Event Timing, CEX Funding, and Wallet Routing
The clearest single data point in the packet is the Feb. 28 Iran-strike market. Bubblemaps said four wallets each made around $400,000 in profit betting that the US would strike Iran on Feb. 28, putting that one outcome at roughly $1.6 million across four addresses.
Bubblemaps also pointed to behavior that looks like operational hygiene rather than directional conviction. It said the cluster made minor losing bets on Feb. 20 that likely served to “avoid attention.”
On the funding side, Bubblemaps said the accounts were funded through centralized cryptocurrency exchanges in a tight timeframe. CEO Nicolas Vaiman added that funds were routed through CEXs and third-party services before funding new Polymarket accounts, a template analysts can monitor for similar clusters because it is observable onchain even when the end actor is not.
What’s Known vs. Unproven in the Insider-Trading Allegation
Bubblemaps and Vaiman drew a hard line between suspicious structure and proven insider identity. “While the data platform doesn’t have definitive proof that the accounts belonged to insiders, the onchain trail is ‘symptomatic of someone with an unfair informational advantage,’” Vaiman said.
He also framed the routing as potentially track-covering, without claiming intent as fact. “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.”
That uncertainty is the point traders should keep in mind. The allegation is behavioral: repeated pre-event sizing plus a near-perfect win rate. The missing piece is attribution to a specific insider or organization.
How This Could Change Prediction-Market Risk Pricing
The immediate market impact is not a token repricing story. It is a risk-premium story around access, listings, and regulatory perimeter.
On March 10, Sen. Adam Schiff introduced the DEATH BETS Act to ban federally regulated prediction markets from listing contracts tied to war, terrorism, assassination, and individual deaths. The bill was introduced shortly after six Polymarket traders netted $1 million by betting on the US strike against Iran, linking a headline outcome to a specific policy response.
Regulatory sensitivity is not theoretical demand-side noise. Politics-related contracts are Polymarket’s third-largest category at 12% of notional trading volume, while they are the fifth-largest on Kalshi at 0.7% of weekly trading volume, according to Dune data. If war and death-adjacent contracts become the next policy battleground, platforms may preemptively adjust listings, or liquidity may migrate to venues perceived as less exposed.
The next catalysts are concrete: any committee action, co-sponsors, or hearings for the DEATH BETS Act, and whether its scope expands beyond “federally regulated prediction markets.” Traders also need to watch for new onchain attribution tying the nine-wallet cluster to identifiable entities, plus any changes in listing policies or market availability for war, assassination, and death-related contracts. Category mix and volume shifts in politics-related contracts on Polymarket and Kalshi are a clean proxy for whether demand is holding up under rising scrutiny.
The Real Trade Here Is Regulatory and Platform-Access Risk
I treat this as a market-structure signal, not a solved insider-trading case. A 98% win rate with repeated pre-event timing is enough to intensify scrutiny because it creates a narrative regulators can act on without needing to prove who sat behind the wallets.
The threshold that matters is whether this cluster becomes attributable to a real-world actor or triggers platform-level listing changes. If either happens, the setup starts to look structural rather than narrative-driven, and the practical consequence is tighter access and thinner liquidity in the most headline-sensitive event contracts.
