Mark Zuckerberg has reportedly directed a small Meta team to build a standalone prediction markets app called Arena, moving the Facebook and Instagram parent toward one of the fastest-growing categories in online trading.
The app is expected to operate separately from Facebook, Instagram, WhatsApp and Messenger. Its initial design would use a video-game-style points system that lets users make predictions on real-world outcomes without immediately turning the product into a cash betting platform.
The real-money question has not been ruled out. That part makes Arena more sensitive than a simple social game because prediction markets already sit between finance, gambling, politics, sports and consumer protection. If Meta later adds cash markets, the company would be entering a sector already dominated by Kalshi, Polymarket and a growing group of brokerages and crypto-native platforms.
Meta has not issued a public confirmation of the project. The reported build still matters because a Meta prediction app would push event markets from crypto and trading circles into a mass-market consumer interface backed by one of the world’s largest social platforms.
Prediction Markets Are Moving Mainstream
Arena would arrive during a breakout year for prediction markets. Event-contract platforms have drawn new traders through elections, sports, economic data, corporate milestones and crypto-linked outcomes, with Polymarket and Kalshi becoming the best-known names in the category.
That growth has already pulled traditional finance deeper into the market. Charles Schwab recently joined the prediction-market race with Cboe-linked S&P 500 contracts, while Robinhood and Interactive Brokers have also expanded event-contract access. The category is moving beyond crypto-native speculation toward mainstream brokerage and consumer-finance distribution.
Crypto has been central to that shift because Polymarket turned event trading into a global onchain product. The broader sector recently hit a record $10.8 billion weekly volume surge, helped by sports markets, political contracts and speculative markets tied to major public companies.
A Meta entry would change the distribution map. Kalshi has the regulated U.S. exchange structure. Polymarket has the crypto-native liquidity and global brand. Meta would bring social graphs, recommendation engines, mobile habits and consumer-scale onboarding, even if Arena begins with points rather than money.
Regulation Will Decide How Far Arena Can Go
The legal path is the hardest part of the story. Prediction markets can be framed as forecasting tools, financial event contracts or gambling products depending on the market, payout structure and jurisdiction. That split has already produced lawsuits, blocked access and political pressure.
Kentucky recently sued Kalshi and Polymarket over alleged unlicensed sportsbook activity, while other regulators have challenged sports and political event markets under gambling and consumer-protection rules. India also blocked Polymarket as Kalshi faced prediction-market ban risk, showing how quickly access can change when local authorities treat event markets as online betting.
Meta’s first reported design avoids that immediate fight by using a points system. But the company’s scale would still make moderation, market selection and settlement rules important from day one. A prediction app tied to politics, elections, sports, entertainment or corporate events could attract traders, fans and manipulators at the same time.
Arena is currently a reported internal Meta project, not a launched app. The known details are limited to a standalone mobile product, a small internal team, a points-based prediction design and no confirmed real-money launch plan. Meta’s next public move would need to show whether Arena stays as a social forecasting game or moves toward regulated event contracts that compete directly with Kalshi, Polymarket and brokerage-linked prediction markets.
