[a16z crypto: Prediction market trading volume hits record highs for three consecutive weeks, weekly trading volume reaches $14.4 billion] a16z crypto published an article revealing data showing that prediction market trading volume has hit record highs for the third consecutive week. Last week, the 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 historical high of around $10 billion was surpassed just a week earlier. Additionally, open interest rose to $1.6 billion, marking a record high for the third consecutive week, indicating that the pace of new positions being opened continues to outstrip the pace of positions being closed, leading to an expanding risk exposure of funds. Among these, the growth in non-sports markets has been particularly notable, covering areas such as macroeconomics and unexpected events. Last week, combined trading volume on Kalshi and Polymarket reached $3.6 billion, already exceeding the total market size of all prediction markets last year.
