Kalshi and Polymarket Hit Record $2.7 Billion in Weekly Crypto Volume
Crypto-related prediction market volume on Kalshi and Polymarket reached a record $2.7 billion in a single week, making crypto the second most traded category on both platforms. The record arrived in mid-October 2026, with Kalshi's Bitcoin contracts alone generating over $2 billion in a single week. The growth in prediction markets comes as spot trading volumes across crypto decline, with platforms like Coinbase expanding into prediction markets to attract engagement.
