Polymarket Pledges to Police Trading For US Midterm Elections

The head of investigations at Polymarket is promising to enforce strict trading controls before the U.S. midterm elections, according to a Reuters interview. Shauna Bautista, an ex-FBI investigator and Coinbase analyst, said the company is prepared to identify suspicious activity during the midterms. Polymarket faces pressure from lawmakers concerned about potential threats to national security and election integrity in the rapidly expanding prediction market space.

The international platform settles trades on a blockchain, providing public transparency but ensuring trader anonymity. Critics argue this can lead to misconduct, but Bautista maintains that Polymarket's blockchain offers valuable insights into trader behavior. The company is enhancing its controls and plans to disclose more transparency about its market integrity efforts.

A new web page will detail how Polymarket uses machine learning, blockchain analytics, trade surveillance, open-source research, and third-party services to prevent malicious activity. In other prediction markets news, a federal appeals court ruled that Nevada can impose gambling laws on Kalshi's sports-event contracts, escalating the jurisdictional battle with the Commodity Futures Trading Commission.

The decision conflicts with a previous ruling by the Third Circuit, creating a circuit split that could lead to a Supreme Court resolution with significant implications for prediction markets and state gambling oversight.
