Kalshi became the largest crypto-related prediction market by trading volume in the second quarter, according to the source. Its market share increased by 42% from April and reached 79% by the end of June. The shift indicates that more trading activity is moving to Kalshi, even as Polymarket remains a well-established platform for crypto-native users. The source suggests competition between the two platforms will remain a key focus as trading volumes and market share continue to evolve.
