Svmuu News: a16z crypto posted on X that open interest in prediction markets reached $1.48 billion in the week ending June 15, setting a new all-time high for the second consecutive week. Unlike trading volume, which reflects daily activity, open interest tracks the funds that participants have deployed and that 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 a sustainable market infrastructure. Major events attract large numbers of users, and more traders are staying to participate in a wide range of markets covering politics, economics, culture, and crypto. In a previous report, a16z crypto noted that the combined impact of multiple events, including the World Cup, drove weekly trading volume in prediction markets to a record high of $10.8 billion.
