Coinbase is reportedly testing new features in its app, including prediction-market and tokenized-stock interfaces. Independent researcher Jane Manchun Wong discovered these developments through reverse-engineering the app's publicly available code. The app now includes tabs labeled "Stocks" and "Predictions," with disclosures suggesting that prediction markets will be offered by Coinbase Financial Markets in collaboration with KalshiEX LLC. This testing aligns with Coinbase's upcoming "System Update" event on December 17, where the company is expected to announce new products and business updates.
