Key Takeaways
- Polymarket has joined forces with Chainalysis to identify and prevent insider trading activities
- The DOJ charged a US Army soldier with leveraging classified intelligence for profitable Polymarket wagers
- US senators are now prohibited from participating in prediction market trading following a new amendment
- The platform is pursuing a $400 million funding round with a projected $15 billion company valuation while awaiting CFTC authorization for US operations
- Prediction market trading activity reached $25.7 billion in monthly volume during March 2026
The prediction market platform Polymarket has formed a strategic alliance with Chainalysis, a leading blockchain analytics company, to combat insider trading and fraudulent market activity. The collaboration was officially revealed on Thursday.
The partnership will leverage Chainalysis’s advanced monitoring capabilities to identify questionable trading behaviors and generate blockchain-based evidence suitable for regulatory authorities and law enforcement agencies.
“Polymarket has zero tolerance for insider trading and all forms of market manipulation and fraud. Those attempting such activities will be tracked down and exposed,” the platform stated.
This strategic move follows several high-profile incidents where traders allegedly exploited privileged information related to actual events to generate profits.
Recently, federal prosecutors arrested an on-duty US Army service member. Authorities claim the individual utilized classified military intelligence to execute profitable trades on Polymarket before the apprehension of Venezuela’s former leader Nicolás Maduro became public knowledge.
The partnership announcement coincides with Polymarket’s efforts to secure $400 million in new capital at a $15 billion company valuation, based on reporting from The Information.
Intensifying Regulatory Scrutiny
Simultaneously, the platform is working to obtain authorization from the Commodity Futures Trading Commission for its primary platform’s US operations. Polymarket reached a settlement with the CFTC in 2022 over accusations of providing unauthorized binary options contracts.
The company subsequently acquired QCEX, a derivatives exchange with CFTC registration, and introduced a US-focused version of its platform in the previous year.
On the same day, the US Senate approved modifications to its Standing Rules, implementing an immediate prohibition on senators engaging in prediction market transactions.
New York state authorities have initiated legal proceedings against cryptocurrency exchange operators Coinbase Financial Markets and Gemini Titan, alleging their prediction market offerings breach state gambling regulations.
Trading Activity Continues Upward Trajectory
Notwithstanding the ongoing controversies, prediction market trading activity has experienced remarkable growth. March 2026 saw monthly transaction volumes climb to $25.7 billion, per research from Bitget Wallet and Polymarket.
Retail participants account for a substantial portion of this growth, with behavioral patterns showing a transition toward consistent engagement rather than sporadic betting.
Research examining all Polymarket transactions spanning 2023 to 2025 revealed that merely 3.14% of user accounts demonstrated consistent profitability.
This elite segment, together with professional market makers, accumulated over 30% of total platform profits despite representing less than 3.5% of total accounts.
Shayne Coplan, CEO of Polymarket, emphasized that the Chainalysis collaboration enhances the platform’s existing blockchain transparency capabilities. “This alliance combines that inherent transparency with robust monitoring and enforcement systems,” he explained.
Competing platform Kalshi has similarly invested in anti-insider trading measures as both organizations compete for multi-billion dollar market valuations.
