Odaily Planet Daily reports that a16z crypto posted on X that open interest in prediction markets reached $1.48 billion for the week ending June 15, marking two consecutive weeks of all-time highs. Unlike trading volume, which reflects daily activity, open interest tracks the amount of capital deployed by participants and still at risk. This data has grown approximately sixfold over the past year, indicating that users are maintaining longer-term financial positions and that prediction markets are evolving into enduring market infrastructure. Major events attract large numbers of users, and more traders are staying to participate in a broad range of markets covering politics, economics, culture, crypto, and more.
Previously, a16z crypto reported that the convergence of multiple events, including the World Cup, drove prediction market weekly trading volume to a record high of $10.8 billion.
