Washington —

The prediction site Polymarket referred dozens of accounts that showed signs of potential military insider trading to the Justice Department for investigation, a senior company official told CNN.

The referrals, which have not been previously disclosed, pertained to accounts flagged by a watchdog group in a report published Thursday, but the referrals predated the report.

That nonpartisan organization, the Anti-Corruption Data Collective, said it analyzed a massive trove of publicly available Polymarket data and found 152 accounts that profited about $8 million on war markets – including about the Iran war – and contained several hallmarks of insider activity.

The Justice Department did not respond to CNN’s request for comment Friday. Polymarket itself has not been accused of wrongdoing.
