Polymarket Partners With Chainalysis to Tighten Oversight of Crypto Prediction Markets

Polymarket is a major decentralized prediction market that previously relied on UMA’s optimistic oracle and token-based governance to resolve disputes. Concentrated voting power can leave settlements vulnerable to influence by a small number of participants. The addition of Chainlink and Pyth is intended to let crypto-asset markets resolve automatically using external price data, reducing the risk of human manipulation.

Under the latest changes, Chainlink and Pyth will provide deterministic price data alongside UMA, creating a three-oracle architecture. The priority is to improve settlement accuracy for crypto-asset contracts. Polymarket has announced the adoption of both services, but reports did not disclose a formal launch date, the value of the partnerships or the number of markets included in the initial rollout.

Polymarket is a decentralized prediction market where event contracts let users trade on future outcomes. As its sports contracts expand rapidly, concerns about insider trading and manipulation are also mounting. Industry-wide trading volume quadrupled year on year to $60 billion in 2025, drawing greater scrutiny from U.S. regulators and law-enforcement agencies. Effective self-regulation has become crucial to the industry's pursuit of legitimacy.

Polymarket said on March 10, 2026, that it would work with Palantir Technologies and TWG AI to build a “Sports Integrity Platform.” Financial terms were not disclosed. The system will be powered by Vergence AI, which Palantir and TWG AI jointly developed in 2025, and will provide end-to-end trade surveillance, real-time anomaly detection, screening for prohibited traders and compliance reporting.
