However, April marked the end of a seven-month streak of record monthly volumes, with a 7.4% decrease to $25 billion. Polymarket saw a 23.4% volume decline and a 12.3% drop in active users (to 643,000), while Kalshi experienced a 9.8% volume increase to $14.28 billion. Polymarket is expanding into the U.S. market with increased compliance measures.
AI Analysis: The slowdown suggests a market consolidation phase after rapid growth, highlighting the importance of regulatory compliance as Kalshi's regulated approach drives volume. While Polymarket faces user engagement challenges, its U.S. expansion aims to address these and capitalize on the largest potential user base.
