Meta's latest prediction market application, Arena, has the potential to introduce betting to 3 billion users.

      Mark Zuckerberg has instructed a small team at Meta to develop a prediction market application named Arena, causing a decline in shares for DraftKings and Flutter on Tuesday, according to a report from the New York Times. The app, which will operate independently from Facebook and Instagram, is aimed at competing with existing platforms like Polymarket and Kalshi. Meta has chosen not to comment on this development.

      Initially, Arena will implement a points-based system akin to video games, rather than allowing users to bet real money. The company has not dismissed the possibility of allowing real-money wagering in the future. This distinction is significant due to federal oversight from the Commodity Futures Trading Commission on real-money prediction markets, which are often classified as gambling by regulators worldwide.

      The news led to a decrease in stock prices for established betting and prediction market companies, with DraftKings dropping over 2%, Flutter Entertainment falling approximately 2%, and Robinhood also experiencing a decline. The market's response highlights the competitive threat posed by Meta’s potential reach to its nearly 3 billion monthly active users across Facebook and Instagram, a scale unmatched by current platforms. Although Polymarket and Kalshi have seen rapid growth, their combined monthly trading volume increased from under $5 billion to $24 billion from September 2025 to April 2026, as per Pew Research, it still pales in comparison to Meta's user base.

      The timing of this development is particularly relevant, as the CFTC proposed new regulations on June 10 that would prohibit contracts related to war, assassinations, and terrorism while potentially permitting betting on sporting events. The regulatory landscape for prediction markets in the U.S. is still evolving, and Meta's entry could hasten this process by attracting mainstream consumer interest to a segment that has largely operated in the periphery.

      DraftKings introduced its own Predictions platform in December 2025, but its stock has plummeted 37% in the current year. Its revenue forecast for 2026, estimated at around $6.5 to $7 billion, fell short of the $7.3 billion anticipated by analysts. This discrepancy between its goals in prediction markets and financial results suggests that monetizing this category is more challenging than expected.

      Integrity issues have also plagued prediction markets. In March 2026, both Kalshi and Polymarket implemented new restrictions on insider trading following a series of high-profile cases. A Google engineer faced charges from the Department of Justice for profiting from internal search data on Polymarket, and a U.S. soldier was separately charged for betting on Venezuelan political events using non-public data.

      According to the Times, Arena is one of several new applications Meta is testing, alongside Meta Photos, a media generation tool. Under Zuckerberg's leadership, the company has been branching out beyond its primary social networking products, with recent initiatives like the Meta Business Agent for customer support across WhatsApp, Messenger, and Instagram, in addition to paid subscription features for its apps.

      The decision of whether Meta will create a points-only game or a real-money trading platform will significantly influence the regulatory landscape and competitive dynamics. A points-based option would entirely circumvent CFTC jurisdiction and could launch quickly, while a real-money model would require regulatory approval and compliance structures that Meta has not previously established, but would access a market that can generate billions in monthly trading volume.

      For Polymarket and Kalshi, the threat posed by Meta in either case is serious. A free, points-based prediction game could divert casual users from platforms that rely on active participant engagement to maintain accurate pricing. A real-money platform would directly compete with a company that has more financial resources, engineers, and users than the entire prediction market sector combined.
