CoinMeta data: According to CryptoRank data, it is predicted that the trading volume in the third quarter of 2026 will reach $188 billion, an increase of nearly 70% compared to the previous quarter. Among them, Kalshi as a major participant, contributed the majority of the trading volume, especially in sports event transactions, with transaction amounts exceeding $58 billion in June and July. Nevertheless, there is disagreement among U.S. courts regarding whether Kalshi's sports contracts constitute gambling, and rulings in Ohio and Tennessee have allowed these states to restrict the sale of Kalshi.
