What Meta's 'Arena' Means for Prediction Markets

Meta has begun building a standalone smartphone app called Arena to host prediction markets. Mark Zuckerberg has directed a small team to design the product, which will sit apart from Facebook and Instagram. The company has treated the project as a high internal priority while it tests user interest and product design.

At launch, users will play with points, a play money system that avoids real betting at first, although the company may consider real stakes later. Prediction markets allow participants to buy and sell simple contracts about events, and market prices move as traders act. Arena could compete with existing platforms such as Polymarket and Kalshi, which capture most of the current trading activity.

Polymarket and Kalshi are the two most visible platforms today, and regulators have been wrestling with their legal status in several countries. Kalshi is regulated in the United States while parts of Polymarket continue to operate outside U.S. oversight.
