Kalshi's weekly trading volume reaches $2.3 billion, double that of Polymarket

ChainCatcher News reports that the prediction market platform Kalshi set a new record in the week ending December 21, with a trading volume of $2.3 billion, surpassing competitor Polymarket’s $1.2 billion by 92%, breaking the $2 billion mark for the first time in a single week. The surge in trading volume is related to Kalshi’s integration with the TRON network, supporting TRX and USDT deposits and withdrawals. As of December 23, the platform’s total trading volume has exceeded $23.7 billion. Currently, the sports market remains the largest trading category, with a single market for predicting the American football champion surpassing $65.8 million in trading volume. Prediction markets experienced explosive growth over the past year due to the U.S. presidential election. Polymarket initially maintained a leading position, but since September this year, Kalshi’s activity has begun to increase, and both platforms set new monthly trading volume records in November.
