Crypto Prediction Markets Hit $2.7B Weekly Record

The notional volume of crypto predictive markets reached 2.7 billion dollars in one week in mid-October. This amount adds up the value of all contracts traded on Kalshi and Polymarket, including when the same position changes ownership multiple times. Kalshi’s Bitcoin contracts alone have produced over 2 billion dollars.
