Thin on the left so far

Only 1 of the 10 outlets with a published leaning rating that ran this story are rated left.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

A study by the Anti-Corruption Data Collective found that 152 wallets on the Polymarket International platform traded on inside information about US military operations. The wallets achieved an average win rate of 97.2%, as reported by Devdiscourse. The research, published on 20 August 2026, raises concerns that foreign adversaries could exploit signals from these trades.

The wallets generated $8 million in profits, according to Moneycontrol. The study also noted that copycat trades by bots and wealthy investors may have amplified the signals, as reported by Devdiscourse. Polymarket’s public ledger makes it easier to detect unusual betting patterns, but experts argue that current monitoring measures are inadequate.

The Anti-Corruption Data Collective called for tighter regulation of prediction markets, including banning markets susceptible to insider trading. The study was partly driven by a case involving a US soldier accused of using classified information to bet on political events, as detailed in the full report by Devdiscourse.

What the coverage left out

None of the right-rated digests mentioned the 97.2% win rate reported by Devdiscourse. The left-rated digest from Al-Monitor did not include the $8 million profit figure reported by Moneycontrol. The centre-rated digests from Benzinga and WTVB did not detail the role of copycat trades or the calls for tighter regulation.
