Suspicious trading inflated election-market volumes after outcomes were effectively settled
Large volumes in Polymarket election markets continued after results were effectively decided, with analysis identifying rapid, mostly offsetting trades that generated little profit or loss. In one Ethiopian market, more than $285 million was traded largely on losing candidates, while an analysis found over 98% of more than 38,000 trade loops ended without either side gaining or losing. Experts say the activity resembles wash trading or volume farming, but trader identities are unknown and Polymarket says it blocked the accounts.
Editorial summary · Publisher article
What matters
- About $284 million of Ethiopian-market volume came from pairs of accounts repeatedly trading with each other.
- An analysis found 99.6% of volume in certain weeks of a Romanian market was suspected wash trading.
- Most Ethiopian trade loops lasted a median of nine seconds and produced no meaningful gain or loss.
- The suspected incentive may have been eligibility for a future cryptocurrency-token allocation, though that motive is unconfirmed.
Regulatory significance
Wash trading is prohibited on regulated US financial exchanges and under Polymarket’s terms. The CFTC declined to say whether it is examining the trades, while the report notes that the agency has investigated other suspected manipulation on the platform.
Context & caveats
- The analysis identifies patterns consistent with manipulation, but unknown trader identities mean wash trading has not been conclusively established.
- Polymarket says it investigated and blocked the accounts after flagging the activity.
