Polymarket Examined After $600 Million Traded on Concluded Elections

Prediction market platform Polymarket recorded more than $600 million in trading volume on election contracts after the races were effectively over, according to an October 15, 2026, investigation by WIRED reporter Kate Knibbs. The post-race activity centered on elections in Ethiopia and Romania, where accounts repeatedly exchanged contracts in circular transactions that generated artificial turnover.

In Ethiopia's federal parliamentary elections, Prime Minister Abiy Ahmed's Prosperity Party secured a dominant majority with 438 seats. Despite the clear outcome, the contract on Polymarket remained open for 123 days following the vote, awaiting formal swearing-in proceedings scheduled for October. During that window, the Ethiopian market logged over $285 million in total volume.

Analysis conducted by MSR Decode showed that approximately $284 million of that sum came from paired accounts buying and selling with one another. Chris Park, head of MSR Decode, found that more than 98 percent of these circular loops produced zero net profit or loss for either participant. While the actual winner, Abiy, drew only $173,000 in volume, more than $41 million was wagered on his chief of staff, Shimelis Abdisa. Barnard College economics professor Rajiv Sethi characterized the pattern directly: "It's obviously some form of volume manipulation."

Resolution Delays and Airdrop Speculation

A similar pattern occurred in Romania's election contract, which stayed open after the original 2024 ballot was annulled over foreign interference concerns. An algorithm monitoring the Romanian contract flagged up to 99.6 percent of weekly volume as suspected wash trading.

Independent analysts attribute the circular trading to activity farming, where users generate synthetic volume to position their accounts for potential future token distributions. Speculation surrounding a token release accelerated after Polymarket CEO Shayne Coplan made public comments addressing the topic on October 14, 2026, though the company has not formally confirmed any token launch or airdrop schedule.

Polymarket global intelligence and investigations head Shana Bautista stated that the company "immediately flagged this activity, investigated, and blocked the accounts from trading." The platform did not explain why the automated paired trading continued over several months before the accounts were removed.
