The open interest in prediction markets has reached a new all-time high for two consecutive weeks, hitting 1.48 billion dollars.

Odaily reports that a16z crypto posted on the X platform, stating that open interest in prediction markets reached $1.48 billion in the week ending June 15, marking a historic high for two consecutive weeks. Unlike trading volume, which reflects daily activity, open interest tracks capital deployed by participants that remains at risk. This figure has grown approximately sixfold over the past year, indicating that users are maintaining longer-term financial positions and that prediction markets are developing into lasting market infrastructure. Major events attract a large number of users, and more traders are staying to participate in a wide range of markets spanning politics, economics, culture, and crypto.

Previously, a16z crypto noted that the resonance of multiple events, such as the World Cup, drove prediction market weekly trading volume to a record high of $10.8 billion.
