Polymarket Details Surveillance Infrastructure as U.S. Midterms Test Prediction Market Controls

Prediction market company Polymarket says it is fully prepared to police trading on its platform during the approaching U.S. midterm elections. Lawmakers have raised concerns that the rapid growth of these markets could open channels for insider trading, threaten national security, and undermine confidence in election outcomes. Several states are separately pursuing legal action to remove prediction markets from sports betting.

Shana Bautista, Polymarket’s global head of investigations and intelligence, told Reuters the company has built the infrastructure to catch irregular trading before and during the midterm cycle. The elections, scheduled in large part for November 3, will test these controls. Bautista said she is confident in the resources available and that systems exist to identify anomalous activity.

Blockchain Data as an Oversight Tool

Polymarket’s international platform settles trades on a blockchain. This structure makes wagers publicly visible while keeping individual traders anonymous, a setup critics argue creates conditions for misconduct. Bautista pushed back on that view, stating the public ledger supplies valuable data to track trading behavior and flag suspicious patterns.

Founded in 2020, the company has expanded its internal controls amid mounting political scrutiny. It plans to launch a webpage that details how it protects market integrity and cooperates with law enforcement. Bautista said the page will outline the use of machine learning, blockchain analytics, trade surveillance, open-source research, and third-party partnerships. The market integrity program itself is not new, but the webpage will provide considerably more detail about how it operates.

Referrals, Compliance, and the Road Ahead

To address lawmaker concerns, Polymarket points to more than 100 cases it has referred to law enforcement. Bautista cited a wallet linked to a U.S. soldier accused by prosecutors of using classified information to bet on the capture of Venezuela’s Nicolas Maduro, along with suspected insider bets tied to U.S. military action in Iran.

The company faces continued questions over compliance with a 2022 settlement with the Commodity Futures Trading Commission, which required it to bar U.S. users from its international platform. Some analysts suggest U.S. users continue to access the platform despite the restriction. Bautista said the systems block the large majority of U.S. users, noting it is difficult at scale to consistently evade all of the guardrails.

The regulatory environment has shifted under the Trump administration, which dropped an investigation into whether Polymarket violated the settlement terms. CEO Shayne Coplan said at the time that the company had been cleared of wrongdoing. Polymarket returned to the U.S. market last year through the acquisition of a U.S.-registered exchange. As reported by Yogonet International, these steps place compliance practices under renewed attention ahead of the elections. Operators will watch whether the surveillance measures hold under electoral pressure and whether referrals translate into sustained regulatory tolerance.
