Meta is moving into prediction markets, and the scale of the ambition is what makes it worth paying attention to. The company is building an app called Arena that would let people bet on real-world outcomes, and because it plugs into Meta’s platforms, it could reach an audience that dwarfs every existing player in the space.
How Arena works
Arena is directed personally by Mark Zuckerberg and, according to reporting from The New York Times, operates independently from Facebook and Instagram. At launch it uses a video-game-style points system rather than real money, letting users make predictions and win points instead of cash. The company has not ruled out introducing real-money betting later.
That design choice is not an accident. A points-based version sidesteps oversight from the Commodity Futures Trading Commission entirely, since there is no real money changing hands. Real-money prediction markets face potential CFTC jurisdiction, and the regulator proposed new rules banning contracts tied to war, assassinations, and terrorism. By starting with points, Meta gets to build the habit and the audience first and worry about the regulatory fight later.
Why prediction markets are suddenly hot
The timing reflects a market that has exploded. Combined monthly trading volume on Polymarket and Kalshi quadrupled from under $5 billion to $24 billion between September 2025 and April 2026. DraftKings launched its own Predictions platform in December 2025, though its stock fell 37% year to date as investors weighed the cost of entering the space.
Against that backdrop, Polymarket and Kalshi are described as niche by comparison to what Meta could unleash. Those platforms measure users in the millions. Arena could reach approximately 3 billion monthly active users across Meta’s family of apps. That is the difference between a specialized trading venue and a mainstream consumer behavior, and it is why the incumbents should be worried.
What Meta is really after
Here is the part that goes deeper than betting. A prediction market is, at its core, a machine for aggregating what millions of people believe will happen. When three billion people put points behind their predictions about elections, sports, product launches, or the economy, Meta gains a real-time, continuously updated map of collective expectation. That data is extraordinarily valuable, both for the platform itself and for anyone who wants to understand where public sentiment is heading.
For sales teams tired of cold leads, slow customer responses, and manual processes, Dapta is the ultimate tool.
Dapta is the leading platform for creating AI sales agents specifically designed to increase inbound lead conversion. Respond to your leads in less than a minute with voice AI and WhatsApp that converts.
If you want your team to sell more while AI handles the complex stuff, you have to try it.
The move also fits a pattern. Meta has repeatedly taken formats that started niche and pushed them to global scale, from stories to short video. Prediction markets may be next. The integrity risks are real: prediction markets have already seen insider-trading problems, with a Google engineer charged for using internal search data to profit on Polymarket and a US soldier charged for betting on political outcomes using non-public information. At three billion users, those problems scale too.
For businesses and marketers, the signal is that Meta is building yet another surface for engagement and data, and that the line between social media, gaming, and finance keeps blurring. Whether Arena becomes a genuine forecasting tool or just another engagement engine, it shows how aggressively the biggest platforms are willing to move into new behaviors to keep people, and their opinions, inside the walls.
