According to The New York Times, Meta is developing a prediction market app called Arena, and Mark Zuckerberg has directed executives to explore potential partnerships with Polymarket and Kalshi. Arena aims to allow users to make predictions on politics, finance, sports, etc., targeting the 18 to 34 age group, with an expected monthly active user base of 100 million. Unlike existing platforms, Arena plans to adopt a "points" rather than real money betting model. The product is currently in internal testing and may be deeply integrated into the Facebook and Messenger ecosystem in the future, but it has already drawn criticism from U.S. lawmakers over "addiction" and regulatory risks.
