14.4 billion weekly trading volume, tenfold growth in one year, and a record high in open interest — this is no longer a niche toy, but the prototype of a serious financial infrastructure.

a16z crypto stated that last week, the weekly trading volume of prediction markets reached $14.4 billion for the first time, setting a new all-time high for the third consecutive week, more than doubling from the approximately $5 billion to $6 billion at the beginning of the year and increasing over tenfold compared to a year ago. Meanwhile, open interest rose to $1.6 billion, also hitting a record for the third straight week, growing about eightfold from last autumn. Last week, Kalshi and Polymarket's non-sports markets (politics, economy, geopolitics, etc.) saw trading volumes of $3.6 billion, already surpassing the entire scale of prediction market trading (including sports) last year.
