Polymarket set a participation record with 477,850 active monthly traders in October

Startup Fortune reports Polymarket monthly active traders hit an all-time high of 477,850 in October, up 93.7 percent from September 246,610 and past the previous peak of 462,600 set in January, according to data reported by The Block. The report says Polymarket monthly volume rebounded to 3.02 billion dollars and the platform listed 38,270 new markets in October, nearly three times August count.

October sets a participation record

Polymarket recorded 477,850 monthly active traders in October, an all-time high, according to Startup Fortune, citing data reported by The Block.

The total rose 93.7 percent from September’s 246,610 and exceeded the previous record of 462,600, set in January. October therefore marked both a sharp monthly increase and a new participation peak.

Volume and market listings expand

Monthly volume rebounded to 3.02 billion dollars, Startup Fortune reported. The supplied summary does not include a September volume figure, so it does not establish how the pace of volume growth compared with the increase in active traders.

Polymarket also listed 38,270 new markets in October, nearly three times August’s count, according to the report. That expansion accompanied the record trader total, although the summary does not identify which markets attracted the most activity.

What it means for prediction markets

  • Participation reached a new high: October surpassed both September’s trader count and January’s previous record. The figures alone do not establish whether that participation will persist.
  • Platform volume is not market-level liquidity: The 3.02 billion dollars in monthly volume measures overall activity; the summary does not show how trading was distributed across individual markets.
  • The market roster grew substantially: October’s 38,270 new listings indicate a larger supply of markets, but the report does not establish how much trading each attracted.
