# Kalshi Sets New Weekly Trading Volume Record

According to ChainCatcher, prediction market platform Kalshi achieved a new milestone in the week ending December 21, with trading volumes reaching $2.3 billion. This marks a 92% increase over its competitor Polymarket's $1.2 billion, and it is the first time Kalshi has surpassed the $2 billion mark in a single week. The surge in trading volume is attributed to Kalshi's integration with the TRON network, which now supports TRX and USDT deposits and withdrawals. As of December 23, the platform's cumulative trading volume has exceeded $23.7 billion. The sports market remains the largest trading category, with a single market predicting the American professional football champion reaching over $65.8 million in trading volume. The prediction market has experienced significant growth over the past year, driven by the U.S. presidential election. While Polymarket initially held the lead, Kalshi's activity began to increase in September, and both platforms set new monthly trading volume records in November.
