Kalshi Dominates Prediction Market Volume as U.S. Trading Surges
Kalshi has surged ahead of Polymarket in the prediction market arena, capturing 62% of total trading volume from Sept. 11 to 17, according to Dune Analytics. Its weekly trading pace exceeded $500 million, dwarfing Polymarket's $430 million. The disparity highlights Kalshi's faster turnover, with an open interest-to-volume ratio of 0.29 compared to Polymarket's 0.38.
Polymarket, however, is making strategic moves to expand its U.S. presence. The platform recently acquired QCX, a regulated derivatives exchange, and partnered with Stocktwits to launch earnings-based markets. These efforts aim to attract stockholders and analysts seeking real-time sentiment gauges.
