Polymarket has investigated 'dozens' of election-related cases

Polymarket says it has investigated dozens of bets connected to the 2026 midterm elections. The company’s election-monitoring operation is run by a 16-member investigations team.

The team uses a surveillance system that combines information from social media, Federal Election Commission records, cryptocurrency activity, banking data, statistical sources and other public information. Polymarket’s investigations chief said the system produces hundreds of alerts each day.

The company’s broader transparency materials describe rules that prohibit insider trading and market manipulation. They also bar wash trading, spoofing, self-dealing and front-running.

Polymarket says it reviews both trading behavior and wallet activity. Its stated tools include machine-learning systems, blockchain analysis, market-surveillance technology and open-source research.

When the company substantiates a violation, it says possible responses include restricting a wallet, pursuing legal action or referring the matter to law enforcement. Polymarket also says each international trade is permanently entered on a public blockchain.

The company’s election investigations and general market-supervision policies show the range of methods it says it uses to identify questionable activity. The available verified information does not establish additional details about any specific criminal or regulatory case.
