Researchers Find $600M in Suspicious Polymarket Election Trades
Analysis cited by Wired found that two Polymarket election markets, tied to Ethiopia and Romania, generated over $600 million in trading volume, much of it after the races had concluded. Researchers identified $284 million in questionable trades around Ethiopia's election and found that 99.6% of trading volume in a Romanian election market during certain periods was flagged as likely wash trading. Polymarket said it flagged and blocked the Ethiopia-related accounts but did not explain why the activity continued for months first.
