Meta is building a prediction markets app to rival Polymarket, Kalshi: report

Mark Zuckerberg has directed a small team at Meta to develop an experimental prediction markets app internally known as Arena. The project aims to rival platforms like Polymarket and Kalshi. Arena will function independently from Meta's existing social networking apps, including Facebook, Instagram, WhatsApp, and Messenger. While the app will likely utilize a video game-like points system instead of monetary wagers, the company has not yet ruled out the eventual implementation of real money betting.
