In a recent development, a prominent tech leaker shared screenshots suggesting a potential integration of prediction markets and stock trading features on the leading cryptocurrency exchange, Coinbase. These revelations, brought to light by Jane Manchun Wong—a known figure in the tech community for her ability to uncover new platform features—showed an upcoming prediction market that could be powered by Kalshi, a major player in the prediction market space, known for its robust trading volume.
Rather than denying these leaks, Coinbase has chosen to build anticipation for an upcoming livestream scheduled for December 17, hinting at new product announcements that mark a “new era” for the platform. A company representative directed inquiries about the leaked features to this livestream, where they promise to unveil exciting updates.
The leaked screenshots indicate that Coinbase’s prediction market may include diverse topics, such as predicting whether former President Donald Trump will release any files related to Jeffrey Epstein. Additionally, Wong’s findings suggest that Coinbase might also be exploring options to facilitate trading of common stocks and exchange-traded funds (ETFs) within its app, although specific stock offerings were not disclosed. Notably, following Wong’s social media share, public access to the prediction market integration appeared to have been withdrawn.
Wong elaborated to Decrypt that her discoveries were made by reverse-engineering the publicly available code of the Coinbase app. Her insights have previously shed light on various features across popular platforms, such as Facebook’s dating service and Airbnb’s integration of flight bookings.
Coinbase’s official stance remained optimistic, inviting users to join the livestream on December 17 to learn more about their upcoming offerings. Their associated post on social media reiterated the transformative changes expected for the platform, promising a plethora of updates.
Furthermore, earlier this month, Kalshi appointed Coinbase Custody to manage its USDC stablecoins. A full-fledged integration between Kalshi and Coinbase for prediction markets would significantly enhance their collaborative efforts, especially as the prediction market sector continues to gain traction, recording billions in trading volume across various platforms.
With a total trading volume of approximately $17 billion, Kalshi stands as the second-largest prediction market after Polymarket, which has seen around $34.39 billion in transactions. The notion of stock trading via cryptocurrency platforms isn’t entirely new; it has been a point of interest for several years. Recent trends show other platforms, such as Robinhood and Kraken, beginning to offer tokenized stocks, which further blurs the lines between traditional finance and the burgeoning crypto landscape.
As Coinbase prepares for their December 17 event, users and investors alike are eager to see how these innovations will reshape the trading experience on the platform and how seamlessly they will integrate with existing features aimed at diversifying user engagement within the crypto ecosystem.
