Key Highlights
- Polymarket has joined forces with Chainalysis to identify and prevent insider trading activities on its platform
- Federal authorities arrested a member of the US Army for allegedly leveraging classified intelligence to place profitable wagers on Polymarket
- The United States Senate approved new rules prohibiting senators from engaging in prediction market trading
- Polymarket aims to secure $400 million in funding at a $15 billion company valuation while pursuing CFTC authorization for US market reentry
- Prediction market platforms recorded $25.7 billion in monthly transaction volume during March 2026
Leading prediction market operator Polymarket has announced a strategic collaboration with blockchain intelligence provider Chainalysis to address insider trading and manipulative trading practices. The platform made the partnership public on Thursday.
The collaboration will equip Polymarket with sophisticated monitoring capabilities to flag questionable trading activity and generate blockchain-based evidence for regulatory bodies and law enforcement agencies.
“Insider trading, in addition to all types of fraud and market manipulation, is not welcome on Polymarket, and those who attempt it will be identified,” the company said in a statement.
This development follows multiple incidents where participants allegedly capitalized on privileged information related to actual events.
Recently, the Department of Justice took into custody an on-duty US Army service member. Authorities claim he exploited classified data to make successful predictions on Polymarket before the apprehension of Venezuela’s former leader Nicolás Maduro.
The timing coincides with Polymarket’s efforts to obtain $400 million in investment capital at a $15 billion company valuation, as reported by The Information.
Increasing Regulatory Oversight
Simultaneously, the platform is working to secure Commodity Futures Trading Commission authorization to resume full operations in the United States. Polymarket reached a settlement with the CFTC in 2022 regarding accusations of providing unauthorized binary options contracts.
Subsequently, the company purchased QCEX, a derivatives marketplace with CFTC registration, and introduced an American version of its platform in the previous year.
Thursday saw the US Senate approve changes to its Standing Rules that establish an immediate prohibition on senators participating in prediction market activities.
New York state authorities have initiated legal proceedings against exchange platforms Coinbase Financial Markets and Gemini Titan, arguing their prediction market offerings breach state gaming regulations.
Transaction Activity Continues Climbing Amid Controversy
Notwithstanding the negative attention, prediction market transaction volume has experienced significant growth. March 2026 saw monthly volume reach $25.7 billion, per analysis from Bitget Wallet and Polymarket.
Individual traders account for a substantial portion of this expansion, with behavioral patterns shifting toward consistent engagement rather than sporadic wagering.
Research from academics 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 liquidity providers, accumulated over 30% of total profits despite representing less than 3.5% of total accounts.
Polymarket CEO Shayne Coplan said the Chainalysis partnership builds on the platform’s on-chain transparency. “This partnership pairs that transparency with the monitoring and enforcement infrastructure to back it up,” he said.
Competing platform Kalshi has similarly been implementing measures to prevent insider trading as both entities pursue valuations in the billions of dollars.
