Prediction market open interest has hit a new all-time high for the second consecutive week, reaching $1.48 billion

Odaily reports that a16z crypto posted on the X platform, stating that prediction market open interest reached $1.48 billion in the week ending June 15, hitting a new all-time high for the second consecutive week. Unlike trading volume, which reflects daily activity, open interest tracks the funds participants have deployed and remain at risk. This metric has grown approximately sixfold over the past year, indicating that users are maintaining longer-term financial positions and that prediction markets are evolving into durable market infrastructure. Major events attract a large number of users, and more traders are staying to participate in a wide range of markets covering politics, economics, culture, crypto, and more.

Previously, a16z crypto stated that multiple events, including the World Cup, synergized to push prediction market weekly trading volume to a new all-time high of $10.8 billion.
