Limits of the breakdown

Rothera, Novig, DraftKings Predictions and Underdog Exchange were included in the $474 million aggregate, but the supplied summary did not provide their individual volumes.

The reported increase establishes a day-over-day rise in trading activity. The available material does not identify which sports or events drove that growth, or how activity changed at each platform.

What it means for prediction markets

  • Kalshi’s $258 million total makes it the largest disclosed contributor to the reported sports-market volume.
  • Polymarket US and Polymarket have separate figures; readers comparing platforms should preserve that distinction.
  • The 17 percent increase describes trading volume, not a change in event probabilities. The supplied figures contain no contract-level pricing or liquidity data.
