Kalshi and Polymarket US Set October Volume Records Ahead of Midterms

  • —Kalshi accounted for 83% of combined volume across the three platforms, Polymarket Global for about 17%
  • —Kalshi's October volume a year earlier was $4.4 billion, a 14.8x increase
  • —The two US-regulated venues generated 95.6% of activity across all three platforms
  • —Robinhood's prediction-market business posted $173 million in Q3 revenue versus $120 million from crypto
Why it matters: The November 3 midterms will test whether political contracts can become a second major driver of prediction-market volume beyond sports.
