Polymarket Enlists Chainalysis to Combat Insider Trading Amid US Expansion Plans

Key Takeaways

• Polymarket has formed a strategic alliance with Chainalysis for insider trading detection and prevention
• Federal authorities arrested a US military member for allegedly using secret intelligence to place bets on the platform
• The Senate approved new regulations prohibiting lawmakers from participating in prediction market trading
• The platform aims to secure $400 million in funding at a $15 billion company valuation while pursuing CFTC authorization for US operations
• Prediction market trading activity reached $25.7 billion in monthly volume during March 2026

The decentralized prediction market platform Polymarket has formed a strategic collaboration with Chainalysis, a leading blockchain intelligence company, to strengthen its defenses against insider trading and fraudulent market activities. The partnership was officially revealed on Thursday.

Through this collaboration, Chainalysis will deliver advanced analytical capabilities to identify abnormal trading behaviors and generate blockchain-backed documentation for governmental and regulatory investigations.

This strategic move follows multiple incidents where traders allegedly leveraged confidential information related to real-world developments to generate profits.

Recently, federal prosecutors charged an on-duty US Army servicemember with exploiting classified military intelligence to make profitable wagers on Polymarket prior to the apprehension of Venezuela’s former leader Nicolás Maduro.

The partnership announcement coincides with Polymarket’s efforts to obtain $400 million in investment capital at a proposed $15 billion company valuation, as reported by The Information.

Intensifying Regulatory Environment

Simultaneously, the company is actively seeking regulatory clearance from the Commodity Futures Trading Commission to restore full operations within the United States. Polymarket reached a settlement agreement with the CFTC in 2022 over accusations of providing unauthorized binary options trading products.

Subsequently, the platform purchased QCEX, a derivatives trading venue with CFTC registration, and introduced an American version of its marketplace last year.

This Thursday, the US Senate approved a modification to its Standing Rules that establishes 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 activities under state legislation.

Trading Activity Continues Upward Trajectory

Despite mounting regulatory challenges, prediction market platforms have experienced explosive growth in user activity. Trading volumes climbed to $25.7 billion for the month of March 2026, according to joint research from Bitget Wallet and Polymarket.

Individual retail participants represent the primary force behind this expansion, with behavioral patterns shifting from sporadic wagering to sustained engagement.

A comprehensive academic investigation examining all Polymarket transactions spanning 2023 to 2025 revealed that merely 3.14% of user accounts demonstrated consistent profitability.

This elite segment, combined with professional market makers, accumulated over 30% of total platform profits despite representing less than 3.5% of all registered accounts.

Competing platform Kalshi has similarly implemented measures to prevent insider trading as both organizations compete for multi-billion dollar market valuations.
