Kalshi’s October 30 turnover outpaces Polymarket in CryptoStruct data

CryptoStruct's tick-by-tick capture for October 30 shows Kalshi turnover far ahead of Polymarket, with predict.fun adding 10.5 million dollars across 772,611 trades the same day.

Kalshi recorded 13.9 million trades and 512.4 million dollars in turnover on October 30, according to CryptoStruct. The figures put its turnover well above Polymarket’s 78.9 million dollars for the same day.

A one-day comparison across three platforms

CryptoStruct’s tick-by-tick capture also included predict.fun, which registered 10.5 million dollars in turnover across 772,611 trades on October 30.

Among the three platforms, Kalshi had the highest reported turnover, followed by Polymarket and predict.fun. The summary did not provide a trade count for Polymarket.

Scope of the figures

The figures appeared in an update published on Oct 31, 2026 at 6:45 PM ET. They describe activity for October 30 rather than a longer-term trend.

The supplied summary provides platform-level totals, but no breakdown by contract or market category. It therefore does not identify which events accounted for the differences in turnover.

What it means for prediction markets

  • Kalshi led on reported turnover: CryptoStruct’s figures show a substantial gap between Kalshi and the other two platforms on October 30.
  • Trade-count comparisons are incomplete: Counts were supplied for Kalshi and predict.fun, but not Polymarket.
  • The snapshot has limits: A single day’s platform totals do not establish a sustained trend or show how activity was distributed across individual markets.
