a16z crypto: Prediction market trading volume hits a new record for three consecutive weeks, with weekly volume rising to $14.4 billion

Odaily reports that data released by a16z crypto shows prediction market trading volume has set a new all-time high for the third consecutive week. Last week, total market trading volume reached $14.4 billion for the first time, a significant increase from approximately $5–6 billion at the beginning of the year. The previous peak of around $10 billion was set just a week prior. Additionally, open interest rose to $1.6 billion, hitting a new record for the third straight week, indicating that the pace of new position opening continues to outpace closing, resulting in ever-expanding capital exposure. Notably, growth in non-sports markets—covering areas such as macroeconomics and unexpected events—has been particularly pronounced. Last week, combined trading volume on Kalshi and Polymarket reached $3.6 billion, already surpassing the total volume of all prediction market categories last year.
