Polymarket, Kalshi cumulative trading volume tops $150 billion in April

The combined streak of record monthly trading volumes at Polymarket and Kalshi stalled in April, though their cumulative trading volume topped $150 billion, The Block Crypto reported. Prediction-market trading, which had surged since September, slowed for the first time, led by declines on Polymarket’s global platform. Polymarket’s U.S. unit and Kalshi continued to grow. Both companies kept their lead positions, while Kalshi expanded in sports betting amid rising pushback from state regulators.
