Mark Zuckerberg wants Meta to build a prediction markets app. The project, internally called Arena, would let users bet on real-world events ranging from elections to sports.

What Arena actually looks like

Arena is being designed as a standalone app, separate from Facebook, Instagram, WhatsApp, and Messenger. The initial version will reportedly use a gamified points system rather than real money. Real-money betting hasn’t been ruled out, though. It’s described as a future possibility.

The project is classified internally as a high-priority experimental venture.
