Kalshi accounts for the largest share

Kalshi contributed 304 million dollars to the total, putting it ahead of Polymarket US, which recorded 104 million dollars, according to DeFi Rate. Kalshi’s volume represented more than half of the reported activity across the seven platforms.

Arizona vs Texas Tech was the most actively traded sports market, with 2.8 million dollars in volume, according to DeFi Rate.

What it means for prediction markets

  • The 17 percent increase shows higher aggregate trading activity over the measured period, but a single daily comparison does not establish a sustained trend.
  • Kalshi’s majority share of reported volume highlights its weight in this cross-platform snapshot.
  • Arizona vs Texas Tech led by trading volume; that ranking alone does not indicate the market’s implied probability for either side.
