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

      TL;DR: Mark Zuckerberg instructed a team at Meta to create a prediction market app called Arena, causing shares of DraftKings and Flutter to drop on Tuesday.

      According to a report from the New York Times, Zuckerberg has tasked a small team at Meta with developing a smartphone application designed to compete with existing prediction market platforms Polymarket and Kalshi. The app, known internally as Arena, will function separately from Facebook and Instagram, although Meta declined to comment on the development.

      Initially, Arena will implement a points-based system resembling video games instead of allowing users to bet real money. However, there is a possibility that real-money wagering could be introduced later. This distinction is important since real-money prediction markets are subject to federal regulation by the Commodity Futures Trading Commission, which has come to view them increasingly as gambling.

      The announcement led to declines in the stock prices of current betting and prediction market companies. DraftKings experienced a drop of over 2 percent, Flutter Entertainment fell about 2 percent, and Robinhood also saw a decrease. This market reaction illustrates the competitive threat Meta's extensive user base poses to smaller platforms.

      Meta has the potential to direct its nearly 3 billion monthly active users from Facebook and Instagram towards a prediction market service, a scale unmatched by existing platforms. While Polymarket and Kalshi have seen swift growth, they remain relatively niche. According to Pew Research, the combined monthly trading volume for both platforms surged from under $5 billion to $24 billion between September 2025 and April 2026, yet this increase is still minuscule compared to Meta’s audience.

      The timing is significant, as the CFTC proposed new regulations on June 10 that would prohibit contracts associated with war, assassinations, and terrorism, while possibly legitimizing bets on sports. The regulatory landscape for prediction markets in the United States is still being developed, and Meta’s entry could hasten this process, attracting mainstream consumer interest to a sector that has mainly operated in the background.

      Despite launching its own Predictions platform in December 2025, DraftKings has seen a 37 percent decline in its stock this year. The company's 2026 revenue forecast of around $6.5 to $7 billion fell short of analysts' expectations of $7.3 billion, suggesting that monetizing prediction markets might be more challenging than incumbents thought.

      Prediction markets have also faced issues with integrity. Both Kalshi and Polymarket established new measures against insider trading in March 2026 following several notable incidents. A Google engineer was indicted for leveraging internal search data to gain profits on Polymarket, and a US soldier was charged for betting on Venezuelan political events using confidential information.

      Arena is among several experimental apps Meta is exploring, as reported by the Times. Other projects include Meta Photos, a media creation tool. Under Zuckerberg’s leadership, the company has been branching out beyond its core social networking offerings, with new initiatives like the Meta Business Agent for customer service on WhatsApp, Messenger, and Instagram, along with paid subscription options for its applications.

      The decision on whether Meta will create a points-only platform or a real-money betting system will influence the future regulatory and competitive landscape. A points-based model would circumvent CFTC oversight entirely and could be launched quickly. Conversely, a real-money option would necessitate regulatory approval and compliance frameworks that Meta has not previously established, but it would enter a lucrative market capable of generating significant monthly volume.

      For Polymarket and Kalshi, the situation is critical in either case. A points-only prediction game from Meta could shift casual users away from platforms reliant on active engagement for accurate pricing. A real-money version would challenge them with a company that possesses more capital, engineers, and users than the entire prediction market sector combined.
