October prediction-market activity rises 25.9 percent across four tracked venues

CryptoStruct, from its own tick-by-tick capture across Kalshi, Polymarket, predict.fun and OG.com, recorded 14.3 billion dollars of turnover in October 2026, up 25.9 percent on the month, on 390.9 million trades. On October 31 alone it captured 566.4 million dollars of Kalshi turnover against 100.8 million dollars on Polymarket.

CryptoStruct recorded 14.3 billion dollars in prediction-market turnover during October 2026, a 25.9 percent increase from the previous month. Its tally covered 390.9 million trades.

The figures come from CryptoStruct’s own tick-by-tick capture of activity across Kalshi, Polymarket, predict.fun and OG.com. They describe that four-venue dataset, rather than an explicitly industry-wide total.

Kalshi leads Polymarket in October 31 snapshot

On October 31, CryptoStruct captured 566.4 million dollars in turnover on Kalshi, compared with 100.8 million dollars on Polymarket. That puts Kalshi ahead of Polymarket for the day in the reported data.

The supplied summary does not break out October turnover by venue or give October 31 figures for predict.fun and OG.com. The daily comparison therefore does not establish how the four platforms ranked over the full month.

What it means for prediction markets

  • The 25.9 percent monthly increase indicates greater aggregate turnover across the tracked venues, but the summary does not identify which platforms or contracts drove that growth.
  • Kalshi’s October 31 turnover exceeded Polymarket’s in CryptoStruct’s capture; a single day is insufficient to establish their relative monthly performance.
  • Turnover and trade counts measure activity. These figures alone do not establish contract-level liquidity or forecasting accuracy.
