Coinbase app code appears to include early prediction market and stock-trading modules
Users of Coinbase, the United States' largest crypto exchange, may soon have access to prediction markets and tokenized stock trading directly inside the app.
Screenshots shared by independent researcher Jane Manchun Wong suggest Coinbase is testing interfaces for prediction markets and tokenized stock trading, months after the company publicly said such features were coming as part of its "everything exchange" initiative.
Wong told The Block that she surfaced the screens — which show tabs for "Stocks," "Predictions," and related disclosures — by reverse-engineering publicly available code from Coinbase's mobile app.
One of the screenshots also includes fine-print language stating that "Prediction markets are offered by Coinbase Financial Markets through KalshiEX LLC," pointing to a potential integration with Kalshi, currently the only federally regulated prediction-market operator in the United States.
The other top prediction-market player, Polymarket, has also been expanding aggressively. The platform quietly relaunched a U.S. beta version earlier this month after acquiring licensed derivatives venue QCX in July, laying the regulatory groundwork for a full domestic return.
Polymarket is already the largest prediction-market platform globally by volume and has recently added major partners such as PrizePicks and Yahoo Finance as it prepares for its wider U.S. rollout.
Coinbase previewed this "everything exchange" strategy in late July, telling CNBC it planned to add tokenized stocks, prediction markets, and early-stage token sales for U.S. customers. Max Branzburg, the company’s vice president of product, said at the time that Coinbase intended to bring "all assets onchain" in a unified interface.
When reached for comment about the newly surfaced screenshots, a Coinbase spokesperson did not confirm or deny the features, saying only: "Tune in to our showcase livestream on December 17th."
That event was first teased earlier this week in a company post announcing a "Coinbase System Update" with "exciting product announcements," "key business updates," and "lots of other cool stuff."
