Polymarket’s combined share slips as Kalshi widens its lead

Polymarket’s international platform and Polymarket US accounted for a combined 17.2% market share, according to Gaming America, citing DeFi Rate’s prediction-market volume tracker.

The report, published Nov 3, 2026 at 3:24 AM ET, described Polymarket’s share as declining while Kalshi extended its lead.

What the available figures show

The 17.2% figure groups Polymarket’s international platform with Polymarket US. The supplied summary does not separate their contributions, limiting comparisons between the two operations.

The available material also provides no previous share figure, measurement period or corresponding percentage for Kalshi. It therefore indicates the direction of the competitive shift without establishing its size or pace.

What it means for prediction markets

  • Combined share is not a platform-level breakdown: The 17.2% figure does not show whether Polymarket’s international platform and Polymarket US experienced similar changes.
  • Relative share does not establish absolute volume: Without volume totals and a comparison period, the reported decline cannot establish whether Polymarket’s activity fell or simply grew more slowly than competitors.
  • Kalshi’s advantage remains unquantified here: The report describes a widening lead, but the supplied material does not give enough figures to calculate the gap.
