Prediction market Polymarket flagged dozens of accounts displaying signs of insider trading on military operations to the Justice Department, a move that comes as the company faces scrutiny over traders profiting from bets tied to classified or tightly held U.S. military operations.

The referrals involved accounts later identified by watchdog group Anti-Corruption Data Collective, which analyzed publicly available Polymarket trading data, CNN reported. The referrals were made prior to the watchdog publishing its findings this week.
