Bitcoin Bettors Push Kalshi and Polymarket to a Record $2.7B Week

Kalshi and Polymarket recorded a combined $2.7 billion in weekly trading, a record, as activity in Bitcoin-related markets helped drive the surge. The volume signals growing use of prediction markets to trade on crypto prices and events, though it does not by itself indicate a directional view on Bitcoin. Bitcoin’s implication is greater visibility and engagement through these platforms, alongside the need to distinguish speculative market activity from spot demand.
