Weekly notional volume in crypto-related contracts on Kalshi and Polymarket reached a record $2.7 billion last week, according to Bloomberg citing Dune Analytics data. The surge was driven primarily by short-term bets on Bitcoin price moves, with other crypto assets contributing to the broader push.
Why it matters
Crypto has now overtaken every category except sports on both platforms, a milestone that signals prediction markets are maturing into a serious venue for directional crypto exposure. The timing is notable: spot trading volumes across major exchanges have been declining, pushing platforms to hunt for new volume pools. Coinbase has already moved, launching a prediction market offering powered by Kalshi, and other exchanges are watching closely.
Market impact
The record volume is a bullish structural signal for the prediction market sector, but a legal overhang complicates the expansion story. Several U.S. states have filed or are pursuing legal challenges against sports prediction contracts on these platforms. If those challenges succeed, they could set precedents that make crypto exchanges more cautious about deepening their prediction market integrations, even if crypto contracts themselves face no direct legal threat today. The $2.7B weekly figure will be the benchmark the market watches to see whether this is a sustained trend or a one-week spike.
