Mark Zuckerberg has reportedly told a small group inside Meta to start building a prediction market app, and it sounds a lot like Polymarket with the engine swapped out.

The New York Times broke the story on Monday, reporting that Zuckerberg directed an internal team at Meta to develop a standalone smartphone app referred to internally as "Arena." It would let users weigh in on the outcome of sporting events, elections, market moves, pop culture moments, and anything else worth wagering an opinion on. For now, users would not be wagering money. Arena is being built around a points system the report compares to a video game, which is a meaningful departure from how Polymarket and Kalshi actually became billion-dollar businesses. Meta has not ruled out adding real-money trading later, which is the kind of phrasing that usually means it is going to add real-money trading later. The app would live outside of Facebook, Instagram, WhatsApp, and Messenger, in its own silo.

Why Now? Because the Sector Just Crossed $130 Billion

Prediction markets used to be a niche curiosity for the politics-and-poker crowd. That changed when Polymarket and Kalshi turned the 2024 US election into a referendum on whether on-chain odds were a better signal than traditional polling. Combined trading volume on the two platforms hit roughly $50 billion in 2025, and it has already cleared $130 billion so far in 2026. Bernstein analysts have floated an estimate that the category could push $1 trillion in annual volume by 2030, which is the kind of number that gets the CEO of a 3-billion-user social network to suddenly clear his afternoon. Zuckerberg's team has described the Arena push as "experimental" but also a "top priority," which in Silicon Valley translation usually means he has been pinging the project lead on weekends.

The BIG Difference - No Cash, No Crypto... For Now

This is where the story gets interesting for anyone who follows crypto. Polymarket runs on Polygon and settles markets in USDC. Kalshi is CFTC-regulated and uses cash. Both made it past the regulatory minefield in different ways, one by being a non-US protocol that lets users trade with stablecoins, the other by becoming a registered designated contract market. Meta's points approach skips both of those battles and lands the app in what is essentially a casual gaming bucket. That gets Arena to market faster, but it also means launch-day users will not be doing the thing that made Polymarket fascinating in the first place, which is putting real skin in the game on the question of who is going to win Iowa. The plan, according to the reporting, is to allow money trading eventually. Whether eventually means months or years is anyone's guess.

Meta's Crypto Track Record Is, How To Put This, Uneven

This is not Meta's first attempt to plant a flag in financial infrastructure. The Libra project, later rebranded Diem, was supposed to be a global stablecoin run by a Switzerland-based consortium. Regulators across half the world made it very clear they would rather chew glass than approve it, and the project was eventually sold off and quietly buried. The company is currently making another attempt at stablecoins, with a reported plan to enter the dollar-pegged token space later this year via a third-party integration, and a USDC creator-payout pilot already running in Colombia and the Philippines. Arena is launching alongside that effort, which means Meta will be juggling a points-based prediction market in one hand and a stablecoin payments rail in the other. If both ship, the integration question gets very interesting very quickly.

Polymarket and Kalshi Investors Did Not Take the News Well

The reaction to the NYT scoop was immediate. DraftKings ended the day off more than 2 percent, FanDuel parent Flutter Entertainment dipped nearly 2 percent before recovering slightly, and Robinhood (which offers prediction market contracts from Kalshi) fell on the same logic. The sell-off was driven by the very simple math that a Meta clone with 3 billion built-in users is the kind of competitor that turns a high-growth category into a brutal one. Polymarket itself remains private and just took a significant funding round at a multibillion-dollar valuation. Kalshi has been on a tear with sports event contracts and political markets. Neither of them needs an existential threat right now, and neither of them gets a vote.

How will this effect the broader market?

That depends on what Zuck's end game is. If Arena launches and becomes a platform using real-money, then all the companies mentioned above will have to deal with the strange scenario where the 'new competition' is starting off with 3 billion users.  But until then, existing markets won't be losing any users to a 'points-only' market - their users are there to play for cash.

For now, the only thing confirmed is that a small team inside Meta has been told to build it. The rest is going to play out one product leak at a time.
