Prediction market platform Polymarket said Thursday that it has teamed with analytics firm Chainalysis to deploy blockchain-based market surveillance tools designed to detect insider trading and enforce compliance rules on the platform.
The collaboration includes investigative tools for generating blockchain-verified evidence, on-chain threat prevention, and professional services covering training, detection development, and complex investigations. Central to the deal is a detection model built on Chainalysis Data Solutions that identifies patterns suggesting insider knowledge in prediction markets.
The compliance upgrade comes as Polymarket experiences explosive growth. The platform first gained mainstream recognition in 2024 around election bets, but has seen surging use so far in 2026, with weekly trading volume either approaching or exceeding $1 billion for most of the year.
"On Polymarket all trades and all settlements are recorded on a blockchain—a level of transparency that traditional markets simply cannot match,” said Chainalysis co-founder and CEO Jonathan Levin, in a statement. “Pairing that transparency with Chainalysis’ data and expertise sets a new standard for market integrity enforcement. With this collaboration, on-chain markets have the potential to be the most trustworthy markets for understanding world events."
