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

The prediction market platform Kalshi set a new record with a trading volume of $2.3 billion in the week ending December 21, 92% higher than its competitor Polymarket's $1.2 billion, marking the first time it surpassed the $2 billion mark in a single week.

The surge in trading volume is related to Kalshi's integration with the TRON network, supporting TRX and USDT deposit and withdrawal services. As of December 23, the platform's cumulative trading volume has exceeded $23.7 billion. Currently, the sports market remains the largest trading category, with the single market predicting the American professional football championship exceeding $65.8 million in trading volume.

The prediction market has experienced explosive growth over the past year due to the U.S. presidential election. Polymarket initially maintained its lead, but since September of this year, Kalshi's activity has begun to increase, with both platforms setting monthly trading volume records in November.
