Zuckerberg’s experimental “Arena” platform signals growing competition in the rapidly expanding prediction markets sector
Meta (META) is reportedly developing a new prediction markets platform called Arena, an experimental standalone app designed to let users forecast future events using a points-based system. According to reports, CEO Mark Zuckerberg has personally directed a small team to build the product, which will operate independently from Facebook, Instagram, WhatsApp, and Messenger.
The news immediately affected financial markets. Shares of sports betting operator DraftKings (DKNG) and trading platform Robinhood (HOOD) declined after reports surfaced, reflecting investor concerns about increased competition. Although Arena will not initially support real-money wagering, Meta’s massive global reach—more than 3.5 billion daily users across its platforms—could quickly make it a major player in the prediction market space.
Arena is not Meta’s first attempt in this category. In 2020, the company launched Forecast, a similar prediction app focused on current events, but discontinued it in 2022. Since then, the industry has grown dramatically. Prediction market platforms such as Kalshi and Polymarket have experienced explosive growth, with combined trading volumes surpassing $130 billion in 2026 alone.
The sector’s expansion has attracted both established betting companies and new entrants, including Trump Media & Technology Group. However, rapid growth has also brought increased regulatory scrutiny, with lawmakers and federal prosecutors investigating allegations of insider trading and market manipulation.
Meta’s latest move highlights the growing mainstream appeal of prediction markets and their potential to reshape digital forecasting and event-based trading.
