- The DOJ recently charged a US Army soldier for allegedly leveraging classified intelligence to profit on Polymarket bets
- US senators are now prohibited from participating in prediction market trading following a new amendment

Blockchain-based prediction market leader Polymarket has entered into a strategic alliance with Chainalysis, a prominent blockchain intelligence company, to strengthen surveillance and enforcement against insider trading and fraudulent market activities. The collaboration was revealed on Thursday.
Through this partnership, Chainalysis will deploy sophisticated monitoring systems designed to flag irregular trading behaviors and generate blockchain-backed documentation suitable for regulatory authorities and law enforcement agencies.
“Polymarket has zero tolerance for insider trading and any form of market manipulation or fraudulent activity. Anyone attempting such behavior will be tracked down and held accountable,” the platform stated in its official announcement.
This strategic move follows multiple high-profile incidents where traders allegedly capitalized on privileged information connected to global political and security events.
Recently, federal prosecutors charged an enlisted member of the US Armed Forces who purportedly exploited classified military intelligence to generate profits on Polymarket by wagering on outcomes related to the apprehension of Venezuela’s former leader Nicolás Maduro.
This partnership announcement coincides with Polymarket’s efforts to secure $400 million in fresh capital at a $15 billion company valuation, as reported by The Information.
Mounting Regulatory Challenges
Simultaneously, the platform is working to obtain authorization from the Commodity Futures Trading Commission to restore full operations within the United States. The company reached a settlement with the CFTC back in 2022 over accusations of providing unauthorized binary options contracts.
Subsequently, Polymarket acquired QCEX, a CFTC-approved derivatives trading venue, and introduced a compliant US-focused service in the previous year.
This week, the US Senate approved a modification to its Standing Rules that creates an immediate prohibition on senators engaging in prediction market transactions.
Meanwhile, New York state authorities have initiated legal proceedings against Coinbase Financial Markets and Gemini Titan, alleging their prediction market offerings constitute illegal gambling under state legislation.
Trading Activity Continues Upward Trajectory
Despite increasing regulatory attention and controversy, transaction volumes across prediction market platforms have experienced remarkable growth. Monthly trading activity climbed to $25.7 billion in March 2026, based on data compiled by Bitget Wallet and Polymarket.
Retail participants represent the primary driver behind this expansion, with behavioral patterns showing a transition from sporadic betting to consistent market engagement.
Research conducted by academic analysts examining all Polymarket transactions spanning 2023 through 2025 revealed that merely 3.14% of user accounts demonstrated characteristics of “skilled winners.”
This limited cohort, combined with professional market makers, accumulated over 30% of total platform profits while representing less than 3.5% of all registered accounts.
According to Polymarket CEO Shayne Coplan, the Chainalysis collaboration enhances the platform’s inherent blockchain transparency. “This alliance combines our on-chain visibility with robust monitoring and enforcement capabilities to support it,” Coplan explained.
Competing platform Kalshi has similarly implemented measures to mitigate insider trading risks as both organizations compete for multi-billion dollar market valuations.
