Mark Zuckerberg Wants Meta in Prediction Markets: Is This His Path to Trillionaire Status?

Mark Zuckerberg has directed a small team at Meta to build a standalone prediction markets app called Arena, which will rival Polymarket and Kalshi, according to a New York Times report.

The news arrives days after Elon Musk became the world’s first trillionaire, and as Kalshi traders rank Zuckerberg among the most likely people to reach $1 trillion next.

Inside Meta’s Arena Prediction Markets App

Meta’s app, known internally as Arena, would run separately from Facebook, Instagram, and WhatsApp, the NYT reported.

The project fits a familiar Zuckerberg pattern of copying rivals, from Instagram Stories against Snapchat to Reels against TikTok and Threads against X (Twitter).

Users would not wager cash at first. Instead, the app would rely on a video-game-style points system, which sidesteps immediate gambling rules but also generates no direct revenue.

However, the company has not ruled out real-money betting later.

The prize is large. Interest in prediction markets climbed after the 2024 US election, and a 2026 funding round valued Kalshi at $22 billion, double its level months earlier, as annualized volume neared $178 billion.

Kalshi raised $1B at a $22B valuation led by Coatue, with participation from Morgan Stanley, Sequoia, a16z, and others.

These fast-growing prediction markets let people trade on elections, sports, and economic data, with Kalshi under US regulators and Polymarket on blockchain rails.

Scrutiny is rising too. Regulators are circling the sector, and one analysis found that most Polymarket users lose money.

What the Trillionaire Math Says

Musk reached first trillionaire status on June 12, after SpaceX’s Nasdaq debut. The title is volatile, though. A 16% slide in SpaceX shares has since erased about $240 billion from his fortune, bringing his fortune to roughly $1.08 trillion, Bloomberg‘s index shows.

Unlike Musk, whose wealth spans SpaceX and Tesla, Zuckerberg depends almost entirely on one stock.

On Kalshi, traders gave Zuckerberg about 24% odds of joining the trillionaire club next on June 23, after Nvidia’s Jensen Huang at 50% and Jeff Bezos at 30%.

That market is thin, however, with only about $7,500 traded, so the figure is soft.

Forbes puts Zuckerberg at $222 billion, fifth in the world. His fortune would need to roughly quintuple to reach $1 trillion.

Almost all of it sits in Meta stock, where he owns about 13%, so the company’s $1.45 trillion value would have to swell past $7 trillion.

Zuckerberg’s costly bets do not always land. Meta’s Reality Labs has lost more than $70 billion since 2020.

A points-based Arena would earn nothing at launch, leaving Meta’s AI and advertising engine to drive any real move toward $1 trillion.

Kalshi’s trillionaire contracts run through 2033 on thin volume. Oxfam projected in 2025 that five people could cross $1 trillion within a decade, naming Zuckerberg among them.

Whether Arena becomes a real business or a quiet experiment, Zuckerberg’s road to that mark still runs through Meta’s core engine.
