Polymarket volume concentrated in 1 percent of accounts, analysis finds

The concentration figure comes from Anti-Corruption Data Collective analysis cited in coverage of the platforms' midterm election performance. Trading activity on Polymarket remains heavily concentrated among a small share of accounts.

One percent of Polymarket accounts account for 75 percent of the platform’s trading volume, according to World Today Journal, citing analysis by the Anti-Corruption Data Collective.

The finding points to a substantial concentration of trading activity among a small share of accounts, rather than volume being distributed broadly across the platform.

Concentration in the midterm spotlight

World Today Journal cited the analysis in coverage of prediction-market platforms’ midterm election performance. The coverage was published on Nov 6, 2026, at 7:15 AM ET.

The figure describes the distribution of trading volume across accounts. The supplied summary does not establish how many distinct traders those accounts represent or how their activity affected election-market prices.

What it means for prediction markets

  • Trading volume and breadth of participation are different measures: 75 percent of Polymarket volume came from just 1 percent of accounts.
  • The concentration finding alone does not establish whether the platform’s midterm forecasts were accurate or whether particular accounts influenced outcomes.
  • For readers assessing election-market performance, the analysis adds context about participation, but the supplied material does not explain its methodology or measurement period.
