Meta is building Arena, a standalone prediction market app greenlit by Mark Zuckerberg.
Arena is described internally as experimental but a top priority.
Strip away the branding and a prediction market is simple: users forecast whether a specific event will happen, and the platform tracks who was right.
Prediction markets are having a moment, and it is a loud one.
This is early reporting on an internal project, so the immediate moves are mostly about positioning rather than a public launch.
Read the complete breakdown, fixes and what happens next.
