- US senators are now prohibited from participating in prediction market trading following a new amendment

The prediction market operator Polymarket has formed a strategic alliance with Chainalysis, a leading blockchain analytics company, to address concerns about insider trading and fraudulent market activity. The collaboration was revealed by the company on Thursday.
The partnership will equip Polymarket with sophisticated detection capabilities to identify questionable trading behavior and generate blockchain-backed evidence suitable for regulatory authorities and law enforcement agencies.
“Polymarket has zero tolerance for insider trading and any form of market manipulation or fraudulent activity. Bad actors will be caught and held accountable,” the platform stated in its official announcement.
This strategic move follows several high-profile incidents where market participants seemingly leveraged confidential information to gain unfair advantages on event outcomes.
Recently, federal prosecutors charged a serving member of the US Armed Forces who purportedly exploited classified intelligence to make profitable wagers on Polymarket before the apprehension of Venezuela’s former leader Nicolás Maduro.
The timing of this partnership coincides with Polymarket’s efforts to secure $400 million in fresh capital at a projected valuation of $15 billion, based on reporting from The Information.
Intensifying Regulatory Environment
Simultaneously, the company is working to obtain clearance from the Commodity Futures Trading Commission to resume full operations within the United States. Polymarket reached a settlement with the CFTC back in 2022 over accusations of providing unauthorized binary options contracts.
Subsequently, the platform acquired QCEX, a derivatives exchange operating under CFTC regulation, and introduced a US-compliant version of its service in the previous year.
On Thursday, the US Senate approved modifications to its Standing Rules that establish 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 breach state gaming regulations.
Trading Activity Continues Explosive Growth
Notwithstanding mounting scrutiny, prediction market platforms have witnessed remarkable growth in trading activity. Volume totals hit $25.7 billion for the month of March 2026, as documented in a joint analysis by Bitget Wallet and Polymarket.
Everyday traders comprise the majority of this expansion, with participation patterns evolving from sporadic engagement to sustained regular activity.
Research conducted by academic investigators examining all Polymarket transactions spanning 2023 through 2025 revealed that merely 3.14% of user accounts demonstrated “skilled winner” characteristics.
This elite minority, combined with professional market makers, collected over 30% of total platform profits despite representing less than 3.5% of total accounts.
Shayne Coplan, CEO of Polymarket, emphasized how the Chainalysis collaboration enhances the platform’s existing blockchain transparency features. “This alliance combines our transparent on-chain infrastructure with comprehensive monitoring and enforcement capabilities,” he explained.
Competing platform Kalshi has similarly implemented measures to combat insider trading risks as both companies compete for billion-dollar market valuations.
