Settled-market counts show the scale gap: Kalshi settled 32,835 markets in September 2026, Polymarket 12,392

Kalshi's settled count has surged from 564 in January 2025, while Polymarket's slipped from an April 2026 peak of 21,686 — a volume/metrics snapshot not featured in any…

September settlements show a scale gap

Kalshi settled 32,835 markets in September 2026, compared with 12,392 for Polymarket, according to Blockonomi. The figures put Kalshi ahead on settled-market count, a measure of how many markets reached completion rather than how much money traded.

The snapshot, published on Oct 15, 2026 at 11:54 AM ET, highlights different trajectories for the two platforms. Kalshi’s count has risen sharply from its earlier baseline, while Polymarket’s September total was below its recent peak.

Different paths to September

According to Blockonomi, Kalshi settled 564 markets in January 2025. Its September 2026 total of 32,835 marks a substantial expansion in the number of markets settling on the platform.

Polymarket’s settled-market count peaked at 21,686 in April 2026, according to Blockonomi. By September 2026, that figure had fallen to 12,392.

These figures establish a gap in settlement activity, but the supplied material does not include trading volume, liquidity or user counts. They therefore do not establish which platform led on those measures.

What it means for prediction markets

  • The metric matters: Kalshi led on September 2026 settled-market count; that is not the same as a lead in trading volume.
  • The comparison period matters: Kalshi’s growth is measured against January 2025, while Polymarket’s decline is measured against its April 2026 peak.
  • Scale needs context: Settlement counts alone do not show how much trading interest or liquidity each completed market attracted.
